spring cloud gateway modify response headersspring cloud gateway modify response headers

The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. Standard policies to change default 3scale APIcast behavior 3scale provides built-in, standard policies that are units of functionality that modify how APIcast processes requests and responses. .filters(f -> f.addRequestHeader("header1", "header-value-1")) The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. The following example configures a MapRequestHeader: This adds the X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. Spring Cloud Gateway Response Modification Raw README.md Overview As of this writing, there's a somewhat limited/restrictive means of applying HTTP response transformations/modifications via Spring Cloud Gateway, probably because it needs to accommodate both the Mono and Flux (aka "reactive") models. The XForwarded Remote Addr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). A steady rate is accomplished by setting the same value in replenishRate and burstCapacity. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. This interface and its usage are subject to change in future milestone releases. It offers a simple way to manipulate the request path by allowing templated segments of the path. Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. To disable it, set the following property: This will default to true in a future release. Each item defines the name and the arguments of a given predicate. This predicates matches the Host header that matches the pattern. The PreserveHostHeader GatewayFilter factory has no parameters. spring.cloud.gateway.filter.local-response-cache.size: Sets the maximum size of the cache to evict entries for this route (in KB, MB and GB). The following example configures a SaveSession GatewayFilter: If you integrate Spring Security with Spring Session and want to ensure security details have been forwarded to the remote process, this is critical. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. Post global filters are usually used in spring cloud gateway to perform operations on response like adding some headers or modifying response body or response status etc. connect-timeout must be specified in milliseconds. This is the number of tokens taken from the bucket for each request and defaults to 1. Tripping The Circuit Breaker On Status Codes, 12.4.1. While a Gateway is running you can use kubectl scale to modify the number of replicas. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 This route matches if the request has a Host header with a value of www.somehost.org or beta.somehost.org or www.anotherhost.org. You can customize the way that the remote address is resolved by setting a custom RemoteAddressResolver. return routeBuilder.routes() Code Revisions 1 Stars 14 Forks 3. It must be a Java System Property, not a Spring Boot property. @ryanjbaxter thanks, the core code is a filter https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt ,but it can't modify header in a post filter,is it a right way writing like this? to the exchange attributes. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. 4.1. exceptions: A list of thrown exceptions that should be retried. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. In some cases you might want to trip a circuit breaker based on the status code To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. This uses the URI templates from Spring Framework. Those values are then available for use by GatewayFilter factories. Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. The url parameter should be a valid URL. This is of particular use when using something like Spring Session with a lazy data store, and you need to ensure the session state has been saved before making the forwarded call. The filter takes a host parameter. How does it work? For example, given a Gateway that has 1 replica, the following will . The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. The circuit breaker config object takes a list of The SetRequestHeader GatewayFilter factory takes name and value parameters. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. The Host route predicate factory takes one parameter: a list of host name patterns. This filter also automatically calculates the. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. cloudflare tunnel home assistant 19 3407 . This is the value of the Location header. The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. Generally, it will put the identity information into the request header and will not modify the content of the request and response. This section covers common problems that may arise when you use Spring Cloud Gateway. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. To clear the routes cache, make a POST request to /actuator/gateway/refresh. For a production deployment, you can configure the gateway with a set of known certificates that it can trust with the following configuration: If the Spring Cloud Gateway is not provisioned with trusted certificates, the default trust store is used (which you can override by setting the javax.net.ssl.trustStore system property). SpringCloud Gateway After Before Between Cookie Header Host Method Path Query RemoteAddr Weight 5.1 Path spring: application: name: gateway-server cloud: gateway: routes: - id: aaa uri: http://localhost:8001 predicates: - Path=/product/** - id: bbb uri: http://localhost:8002 predicates: - Path=/order/** 5.2 Query I too was experiencing the UnsupportedOperationException when I added a post filter to an existing global filter which had an order that caused the post filter to action to occur after the response had been sent. You can configure additional parameters for each route by using metadata, as follows: You could acquire all metadata properties from an exchange, as follows: Http timeouts (response and connect) can be configured for all routes and overridden for each specific route. There is an abstract class called AbstractRoutePredicateFactory which you can extend. This predicate matches requests that happen after datetime1 and before datetime2. By clicking Sign up for GitHub, you agree to our terms of service and You signed in with another tab or window. Want to remove the "warning cannot modify header information" error from your WordPress website? There are many caching cases on the network, but there are various Bug problems in the testing process. . This is useful when you try to support CORS preflight requests and your route predicate does not evaluate to true because the HTTP method is options. Most examples below use the shortcut way. The following two examples are equivalent: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. Those values are then available for use by GatewayFilter factories. Then the proxy request is made. Modifying the headers is simple because we can obtain a reference to the HttpHeaders map object: exchange.getRequest () .mutate () .headers (h -> h.setAcceptLanguageAsLocales ( Collections.singletonList (requestLocale))) Copy But, on the other hand, modifying the URI is not a trivial task. Spring cloud gateway response body modification. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. forwards the incoming token to outgoing resource requests. Appending multiple headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-append, spring.cloud.gateway.x-forwarded.host-append, spring.cloud.gateway.x-forwarded.port-append, spring.cloud.gateway.x-forwarded.proto-append, spring.cloud.gateway.x-forwarded.prefix-append. Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. The HTTP Cache-Control header allows caching (that means it does not have any of the following values: no-store present in the request and no-store or private present in the response). The RemoveResponseHeader GatewayFilter factory takes a name parameter. Creating and Deleting a Particular Route, 15.8. By default, it creates a NettyChannel by using the default TrustManagerFactory. to your account, I am trying to modify a header of response in a post filter of gateway,the filter handle a cors problem which would filt websockt service ,the websockt service is a micro-service which must been decorated with cors configurationso a websockt request will get a response with multiple header like Access-Control-Allow-Origin, to solve this questioni must modify the response header of the key Access-Control-Allow-OriginHowever ,when i do this, a error occured, java.lang.UnsupportedOperationException: null at org.springframework.http.ReadOnlyHttpHeaders.set(ReadOnlyHttpHeaders.java:99) ~[spring-web-5.1.6.RELEASE.jar:5.1.6.RELEASE] at com.apigw.filter.CORSFilter.lambda$filter$0(CORSFilter.java:84) ~[classes/:na] at reactor.core.publisher.MonoRunnable.call(MonoRunnable.java:73) ~[reactor-core-3.2.8.RELEASE.jar:3.2.8.RELEASE]. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. For a full working sample see this project. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. The following example configures a SetPath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. privacy statement. In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. You can overwrite the names of the headers in the configuration by setting the values of the following arguments (shown with their default values): executionExceptionTypeHeaderName ("Execution-Exception-Type"), executionExceptionMessageHeaderName ("Execution-Exception-Message"), rootCauseExceptionTypeHeaderName ("Root-Cause-Exception-Type"), rootCauseExceptionMessageHeaderName ("Root-Cause-Exception-Message"). method: Method name in the service that handles the request. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. The collection of filters applied to the route. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. If basedOnPreviousValue is true, the backoff is calculated by using prevBackoff * factor. For example, to reference a filter named Something in configuration files, the filter Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services You can use the CacheRequestBody filter to cache the request body before sending it downstream and getting the body from exchange attribute. keyResolver is a bean that implements the KeyResolver interface. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. To enable this, set spring.cloud.gateway.discovery.locator.enabled=true and make sure a DiscoveryClient implementation (such as Netflix Eureka, Consul, or Zookeeper) is on the classpath and enabled. You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. This filter works only with HTTP (including HTTPS) requests. A utility method (called get) is available to make access to these variables easier. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. The RemoveHopByHop Headers Filter removes headers from forwarded requests. *) and the replacement /${remaining}. backoff: The configured exponential backoff for the retries. If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. Route: The basic building block of the gateway. Let's simplify this scenario. The lowercase full name of the secure header needs to be used to disable it.. The RemoveRequestParameter GatewayFilter factory takes a name parameter. it is proxying. The request returns a 200 without a response body. The following example configures a between route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver) and before Jan 21, 2017 17:42 Mountain Time (Denver). The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). A route is matched if the aggregate predicate is true. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? Both offer the same possibilities. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. It uses the Netty HttpClient to make the downstream proxy request. If you would like us to look at this issue, please provide the requested information. URI variables may be used in the value and are expanded at runtime. GatewaySampleApplication.java. Naming Custom Filters And References In Configuration, 18. For relative redirects, you should use uri: no://op as the uri of your route definition. This predicate matches requests that happen before the specified datetime. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. aws api gateway parameter mapping. If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. /resource). If the information is not provided within the next 7 days this issue will be closed. It uses the Host header, scheme, port and path of the current request to create the various headers. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. }, 4. That is not a complete working sample, it is just some code. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. The routine of modifying the response body with Spring Cloud Gateway is the same as the previous request body; Configure routing and filters through code; . Download ZIP. Route filters are scoped to a particular route. You can extend an abstract class called AbstractGatewayFilterFactory. We do this already The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. Modifying the request body is a common requirement. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. The headers with the exception type, message and (if available) root cause exception type and message are added to that request by the FallbackHeaders filter. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} To write a GatewayFilter, you must implement GatewayFilterFactory as a bean. The args key is a map of key value pairs to configure the predicate or filter. You must use $\ to mean $ because of the YAML specification. name can contain a space-separated list of header names. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. Configuring Predicates and Filters For, 15.4. The status parameter should be a 300 series redirect HTTP code, such as 301. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. The RemoveRequestHeader GatewayFilter factory takes a name parameter. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. The following listing shows how it works: This style also allows for more custom predicate assertions. Here, you can modify requests and responses before or after sending the downstream request. So, if the downstream server responded with X-Response-Red:1234, it will be replaced with X-Response-Red:Blue, which is what the gateway client would receive. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled API gateway provides a unified access for services in microservices architecture. Usually it's a common requirement that applications can . It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. Gunzenhausen (German pronunciation: [ntsnhazn] (); Bavarian: Gunzenhausn) is a town in the Weienburg-Gunzenhausen district, in Bavaria, Germany.It is situated on the river Altmhl, 19 kilometres (12 mi) northwest of Weienburg in Bayern, and 45 kilometres (28 mi) southwest of Nuremberg.Gunzenhausen is a nationally recognized recreation area. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. You can also define a rate limiter as a bean that implements the RateLimiter interface. The default request size is set to five MB if not provided as a filter argument in the route definition. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The following example configures a header route predicate: This route matches if the request has a header named X-Request-Id whose value matches the \d+ regular expression (that is, it has a value of one or more digits). spring.cloud.gateway.filter.local-response-cache.timeToLive Sets the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours). Sign in 2016-10-05: 4.3: CVE-2016-6426 CISCO The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. The following listing shows how to cache the request body GatewayFilter: CacheRequestBody extracts the request body and converts it to a body class (such as java.lang.String, defined in the preceding example). Fork 3. Writing Custom GatewayFilter Factories, 17.2.1. In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. Passing headers with Spring Cloud Feign. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). extracts an access token from the currently authenticated user, }) However, you can customize this TrustManager by creating a bean of type GrpcSslConfigurer: This filter allows caching the response body and headers to follow these rules: It caches the response only for one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. If the fallback is called, the request is forwarded to the controller matched by the URI. In future milestone releases, there will be some KeyResolver implementations. return r.host("*.somehost.org").and().path("/somepath") For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. Spring Cloud supports Resilience4J out of the box. Spring cloud gateway response body modification. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). Closing due to lack of requested feedback. For the external controller/handler scenario, headers can be added with exception details. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. The default is http|https|ftp|ftps. If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. When a request is made through the gateway to /json/hello, the request is transformed by using the definition provided in hello.proto, sent to com.example.grpcserver.hello.HelloService/hello, and the response back is transformed to JSON. Am I doing it wrong? The Reactor Netty HttpClient and HttpServer can have wiretap enabled. I think i have to go for a blocking call here. After the proxy request is made, the post filter logic is run. The predicates defined by RouteDefinitionLocator beans are combined using logical and. as the separator. Since 4.0.0, Spring Cloud Gateway supports Spring AOT transformations and native images. How to modify spring cloud gateway response headers, https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt, https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java. This applies the filter to all requests. However, there is one in another application, registered under localhost:9994. The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. if. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter that uses the optional last parameter: This removes attributes "id" and "color" from the JSON content body at any level. consumer can be a pure Client (like an SSO application) or a Resource It seems the response header cannot be modifed in post filter,the following is my code,please tell me a way to solve this problem. response-timeout must be specified in milliseconds. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. NOTE: This is not recommended for production. This handler runs the request through a filter chain that is specific to the request. This vulnerability is known as HTTP Response Splitting. let's see. httpMethod: The HTTP method used for the request. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). So, if the downstream server responded with X-Request-Red:1234, it will be replaced with X-Request-Red:Blue, which is what the downstream service would receive. The following listing shows how to modify a request body GatewayFilter: You can use the ModifyResponseBody filter to modify the response body before it is sent back to the client. I got the root cause. . During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. AddRequestHeader is aware of the URI variables used to match a path or host. The gateway can listen for requests on HTTPS by following the usual Spring server configuration. It is the name of the header to be removed. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency.
