spring cloud gateway modify response headersspring cloud gateway modify response headers

The filter takes a host parameter. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter: This listing adds 2 headers X-Request-Color-1:blue and X-Request-Color-2:green to the downstream requests headers for all matching requests. If the fallback is called, the request is forwarded to the controller matched by the URI. status codes that if returned will cause the circuit breaker to be tripped. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. Creating of individual headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-enabled, spring.cloud.gateway.x-forwarded.host-enabled, spring.cloud.gateway.x-forwarded.port-enabled, spring.cloud.gateway.x-forwarded.proto-enabled, spring.cloud.gateway.x-forwarded.prefix-enabled. The resulting response is similar to the following: The response contains the details of the global filters that are in place. backoff: The configured exponential backoff for the retries. If basedOnPreviousValue is true, the backoff is calculated by using prevBackoff * factor. Sign in URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). value or the String representation of the HttpStatus enumeration. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. 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. The following listing configures a RemoveResponseHeader GatewayFilter: This will remove the X-Response-Foo header from the response before it is returned to the gateway client. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. To write a GatewayFilter, you must implement GatewayFilterFactory as a bean. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. 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). Otherwise, the original value in the client request is sent. The RemoveRequestParameter GatewayFilter factory takes a name parameter. or check if an exchange has already been routed. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; If max-age is present on the original response, the value is rewritten with the number of seconds set in the timeToLive configuration parameter. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. .filters(f -> f.addRequestHeader("header1", "header-value-1")) Called the mutate methods as below: ServerHttpRequest request = exchange.getRequest () .mutate () .header ("headerkey", jwt) .build (); exchange.mutate ().request (request).build (); return chain.filter (exchange); However, the header is not injected to the backend api. If you would like us to look at this issue, please provide the requested information. The following listing configures a RequestSize GatewayFilter: The RequestSize GatewayFilter factory sets the response status as 413 Payload Too Large with an additional header errorMessage when the request is rejected due to size. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. The ServerHttpResponse instance is used to . For each global filter, there is a string representation of the filter object (for example, org.spring[emailprotected]77856cc5) and the corresponding order in the filter chain. It uses the Host header, scheme, port and path of the current request to create the various headers. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. That is not a complete working sample, it is just some code. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. Easy to extend and/or customize using standard Spring patterns pass the authentication token downstream to the services (in this case 25Modify Response Body GatewayFilter Factory; reverse proxies. 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 Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. You can use it inside a regular Spring web handler as a method parameter. The following listing shows how it works: This style also allows for more custom predicate assertions. While a Gateway is running you can use kubectl scale to modify the number of replicas. URI variables may be used in the value and are expanded at runtime. You can combine multiple route predicate factories with logical and statements. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. Configuring Predicates and Filters For, 15.4. The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. You must use $\ to mean $ because of the YAML specification. However, you can also reroute the request to a controller or handler in an external application, as follows: In this example, there is no fallback endpoint or handler in the gateway application. As Spring Cloud Gateway distinguishes between pre and post phases for filter logic execution (see How it Works), the filter with the highest precedence is the first in the pre-phase and the last in the post-phase. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. The default filter is a rewrite path filter with the regex /serviceId/?(?. This interface and its usage are subject to change in future milestone releases. connect-timeout must be specified in milliseconds. In configuration, you can reference the bean by name using SpEL. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. We do this already For a full working sample see this project. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. The following MVC example proxies a request to /test downstream to a remote server: The following example does the same thing with Webflux: Convenience methods on the ProxyExchange enable the handler method to discover and enhance the URI path of the incoming request. 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). CircuitBreaker also supports URI variables in the fallbackUri. Predicate: This is a Java 8 Function Predicate. We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. Like in the case of global configuration, the properties belong to Spring Framework CorsConfiguration. .metadata(CONNECT_TIMEOUT_ATTR, 200); The RemoteAddr Route Predicate Factory, 5.10.1. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. 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. The following example configures /actuator/gateway/routes: This feature is enabled by default. Spring cloud gateway response body modification. Additionally, to set a multi-valued header, use the header name multiple times like AddRequestHeadersIfNotPresent=X-Request-Color-1:blue,X-Request-Color-1:green. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. It is the name of the header to be removed. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. keyResolver is a bean that implements the KeyResolver interface. The pattern is an Ant-style pattern with . .application.yml. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. and puts it in a request header for the downstream requests. The LocalResponseCache runs if its associated property is enabled (spring.cloud.gateway.filter.local-response-cache.enabled) and activates a local cache using Caffeine for all responses that meet the following criteria: The response has one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). If you would like us to look at this issue, please provide the requested information and we will re-open the issue. 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"). Those values are then available for use by GatewayFilter factories. Policy to specify how to modify the response code, body and headers. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). Some situations necessitate reading the request body. responseCode; responseHeaderTransformations; responseMessage; type; . 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. In addition, through the spring.cloud.gateway.metrics.tags.path.enabled property (by default, false), you can activate an extra metric with the path tag: These metrics are then available to be scraped from /actuator/metrics/spring.cloud.gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. 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). 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, @ryanjbaxter it seems a route filter,can i modify a response header in a global post filter,thanks. If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). The name and argument names are listed as code in the first sentence or two of each section. This handler runs the request through a filter chain that is specific to the request. You can add headers to the downstream response by using the header() methods on ProxyExchange. Download ZIP. The following listing configures a RewriteLocationResponseHeader GatewayFilter: For example, for a request of POST api.example.com/some/object/name, the Location response header value of object-service.prod.example.net/v2/some/object/id is rewritten as api.example.com/some/object/id. The AddRequestHeader GatewayFilter factory takes a name and value parameter. Route: The basic building block of the gateway. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. Raw. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. The default request size is set to five MB if not provided as a filter argument in the route definition. status: The HTTP status of the request returned to the client. 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. Note that the null value is due to an incomplete implementation of the endpoint controller, because it tries to set the order of the object in the filter chain, which does not apply to a GatewayFilter factory object. The datetime2 parameter must be after datetime1. .uri("http://someuri") To configure Global http timeouts: None of the prior documentation applies to what follows. extracts an access token from the currently authenticated user, If it is not provided, the value of the Host request header is used. It adds the Host header, scheme and port of the current request to any existing Forwarded header. To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. 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). The pile of explanations in front of Xinchen still don . Acompanhe-nos: can gabapentin help with bell's palsy Facebook 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 following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. AddResponseHeader is aware of URI variables used to match a path or host. 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. If You Appreciate This, You Can Consider: We are thankful for your never ending support. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. application.yml. . 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 Forwarded Headers Filter creates a Forwarded header to send to the downstream service. If none of these parameters are configured but the global filter is enabled, by default, it configures 5 minutes of time to live for the cached response. It offers a simple way to manipulate the request path by allowing templated segments of the path. 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. httpMethod: The HTTP method used for the request. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. aws api gateway parameter mapping. This is the rate at which the token bucket is filled. You can configure the logging system to have a separate access log file. A burst of 20 is allowed, but, in the next second, only 10 requests are available. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. /resource). GitHub spring-cloud / spring-cloud-gateway Public Notifications Fork 2.9k Star 3.9k Code Issues 337 Pull requests 39 Actions Projects Security Insights New issue How to modify spring cloud gateway response headers #1092 Closed The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. Spring Cloud supports Resilience4J out of the box. Server. This filter works only with HTTP (including HTTPS) requests. The DedupeResponseHeader filter also accepts an optional strategy parameter. 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. The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int). This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. application.yml. 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]. name can contain a space-separated list of header names. It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. 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. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. - thaneesh shanand Apr 16, 2018 at 1:05 The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a . All pre filter logic is executed. This vulnerability is known as HTTP Response Splitting. the request should only be allowed if it comes from a trusted list of IP addresses used by those Both offer the same possibilities. The reason the filters are divided by the dotted line is that filters can run logic both before and after the proxy request is sent. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. In future milestone releases, there will be some KeyResolver implementations. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. This uses Java regular expressions for a flexible way to rewrite the request path. 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. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. This filter also automatically calculates the. Here, you can modify requests and responses before or after sending the downstream request. It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). The following listing configures a RemoveRequestHeader GatewayFilter: This removes the X-Request-Foo header before it is sent downstream. The By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. The following example configures a cookie route predicate factory: This route matches requests that have a cookie named chocolate whose value matches the ch.p regular expression. It runs after all other filters have completed and writes the proxy response back to the gateway client response. The input type is a Spring Framework ServerWebExchange. The maxSize parameter is the maximum data size allowed by the request header (including key and value). The collection of filters applied to the route. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). Created 6 years ago. Route filters are scoped to a particular route. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. Each item defines the name and the arguments of a given predicate. This is the value of the Location header. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. Cleanliness 4.4. This is the number of tokens taken from the bucket for each request and defaults to 1. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. This section covers common problems that may arise when you use Spring Cloud Gateway. consumer can be a pure Client (like an SSO application) or a Resource The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. The algorithm used is the Token Bucket Algorithm. 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. The Host route predicate factory takes one parameter: a list of host name patterns. Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. A Token Relay is where an OAuth2 consumer acts as a Client and The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. If it is not matched, the filter does nothing. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. The Between route predicate factory takes two parameters, datetime1 and datetime2 The KeyResolver is a simple one that gets the user request parameter The errorHeaderName parameter sets the name of the response header containing an error message, by default it is "errorMessage". The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). status codes you want to trip the circuit breaker you can either use an integer with the status code 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. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. If the information is not provided within the next 7 days this issue will be closed. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. SetResponseHeader is aware of URI variables used to match a path or host. 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.
