spring cloud gateway modify response headers

This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. Typically, there will be a name key and an args key. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. 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 youre using load-balanced routes, you need to explicitly define your. The following example configures an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. connect-timeout must be specified in milliseconds. To add this functionality to the gateway, you need to add the TokenRelayGatewayFilterFactory like this: and it will (in addition to logging the user in and grabbing a token) For a full working sample see this project. .filters(f -> f.addRequestHeader("header1", "header-value-1")) SetResponseHeader is aware of URI variables used to match a path or host. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. Oracle Cloud Infrastructure SDK for TypeScript and JavaScript API Reference - 2.53.1. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. I got the root cause. The first one is the import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean The following example shows how to use the get method: The Query route predicate factory takes two parameters: a required param and an optional regexp (which is a Java regular expression). The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. To provide the same CORS configuration to requests that are not handled by some gateway route predicate, set the spring.cloud.gateway.globalcors.add-to-simple-url-handler-mapping property to true. Response data is not cached if Cache-Control header does not allow it (no-store present in the request or no-store or private present in the response). import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. A per-route response-timeout with a negative value will disable the global response-timeout value. If the input header does not exist, the filter has no impact. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] A Token Relay is where an OAuth2 consumer acts as a Client and URI variables may be used in the value and are expanded at runtime. AddResponseHeader is aware of URI variables used to match a path or host. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. 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. The route configuration allows applying CORS directly to a route as metadata with key cors. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. 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 listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. Properties. 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. In configuration, you can reference the bean by name using SpEL. See the documentation for @RequestMapping in Spring MVC for more details of those features. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. Spring Cloud Gateway. Those values are then available for use by GatewayFilter factories. There are many caching cases on the network, but there are various Bug problems in the testing process. With MVC, it also supports forwarding to a local handler through the forward() method. Spring cloud gateway response body modification. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). /resource). Fully expanded arguments appear more like standard yaml configuration with name/value pairs. Easy to extend and/or customize using standard Spring patterns If the response is already cached and a new request is performed with no-cache value in Cache-Control header, it returns a bodiless response with 304 (Not Modified). Then the proxy request is made. Modifying the request body is a common requirement. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. The weights are calculated per group. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. Passing headers with Spring Cloud Feign. Modify request body. You can extend an abstract class called AbstractGatewayFilterFactory. This predicate matches cookies that have the given name and whose values match the regular expression. a circuit breaker. You can configure the logging system to have a separate access log file. Removes an existing route from the gateway. 2016-10-05: 4.3: CVE-2016-6426 CISCO The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). For relative redirects, you should use uri: no://op as the uri of your route definition. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. 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. Want to remove the "warning cannot modify header information" error from your WordPress website? application.yml. Each item defines the name and the arguments of a given predicate. httpStatusCode: The HTTP Status of the request returned to the client. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. If it is not matched, the filter does nothing. The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. However, there is one in another application, registered under localhost:9994. The following listing shows how it works: This style also allows for more custom predicate assertions. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. must be in a class named SomethingGatewayFilterFactory. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. 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. 3,AddResponseHeader GatewayFilter Factory. There are convenience methods that you can use to mark an exchange as routed it is proxying. keyResolver is a bean that implements the KeyResolver interface. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. The RemoteAddr Route Predicate Factory, 5.10.1. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. The Host route predicate factory takes one parameter: a list of host name patterns. You can also manipulate response headers (and anything else you like in the response) by adding a mapper to the get() method (and other methods). 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. Well occasionally send you account related emails. Configure for High Availability. I think i have to go for a blocking call here. APIcast standard policies return routeBuilder.routes() }) The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. Creating and Deleting a Particular Route, 15.8. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. 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 algorithm used is the Token Bucket Algorithm. Embed. This filter also automatically calculates the. 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 RemoveRequestParameter GatewayFilter factory takes a name parameter. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. 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). 4.1. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). The URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. 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]. It must be a Java System Property, not a Spring Boot property. The default request size is set to five MB if not provided as a filter argument in the route definition. It can be used as API gateway in microservice architecture and supports dynamic routing and filtering functions. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. 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. response-timeout must be specified as a java.time.Duration. It does not work in a traditional Servlet Container or when built as a WAR. By default, it creates a NettyChannel by using the default TrustManagerFactory. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. This strips the service ID from the path before the request is sent downstream. This filter works only with HTTP (including HTTPS) requests. This section covers common problems that may arise when you use Spring Cloud Gateway. Feign is a great way to communicate between services and send data like a JSON request body, single header or multiple headers and much more. The following listing configures a SetRequestHostHeader GatewayFilter: The SetRequestHostHeader GatewayFilter factory replaces the value of the host header with example.org. The FallbackHeaders factory lets you add Spring Cloud CircuitBreaker execution exception details in the headers of a request forwarded to a fallbackUri in an external application, as in the following scenario: In this example, after an execution exception occurs while running the circuit breaker, the request is forwarded to the fallback endpoint or handler in an application running on localhost:9994. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. For example, you might want to extract the trailing elements of a path to pass them downstream: All the features of Spring MVC and Webflux are available to gateway handler methods. For the external controller/handler scenario, headers can be added with exception details. 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. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. exceptions: A list of thrown exceptions that should be retried. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. The following example below is invalid: The Redis implementation is based on work done at Stripe. method: Method name in the service that handles the request. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. It uses the Netty HttpClient to make the downstream proxy request. name can contain a space-separated list of header names. Both offer the same possibilities. This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. You can combine multiple route predicate factories with logical and statements. For example, setting replenishRate=1, requestedTokens=60, and burstCapacity=60 results in a limit of 1 request/min. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. outcome: The outcome, as classified by HttpStatus.Series. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. You must use $\ to mean $ because of the YAML specification. Have a question about this project? 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. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. It accepts the first parameter to override the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours) and a second parameter to set the maximum size of the cache to evict entries for this route (KB, MB, or GB). The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. Displays the list of routes defined in the gateway. 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. The ServerHttpResponse instance is used to . Acompanhe-nos: can gabapentin help with bell's palsy Facebook the request should only be allowed if it comes from a trusted list of IP addresses used by those value or the String representation of the HttpStatus enumeration. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. For example, when we use Spring Cloud Gateway to implement the gateway, we need to implement a function: parse the JWT stored in the request header, extract the user ID in it, and then write it to the request body. It offers a simple way to manipulate the request path by allowing templated segments of the path. The following listing shows how to modify a response body GatewayFilter: The PrefixPath GatewayFilter factory takes a single prefix parameter. This lets you match on anything from the HTTP request, such as headers or parameters. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. 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. It uses Java regular expressions for a flexible way to rewrite the response header value. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. The circuit breaker config object takes a list of How does it work? To write a GatewayFilter, you must implement GatewayFilterFactory as a bean. Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . You can enable, disable, or configure policies to control how they modify APIcast. Once a request has been marked as routed, other routing filters will not route the request again, Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. Star 14. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. Modifying the Way Remote Addresses Are Resolved, 5.12. Generally, it will put the identity information into the request header and will not modify the content of the request and response. - thaneesh shanand Apr 16, 2018 at 1:05 So a request to /hello is sent to /mypath/hello. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. There should be no reason why a filter cannot modify a response header. The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. A route is matched if the aggregate predicate is true. The RemoveRequestHeader GatewayFilter factory takes a name parameter. To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute.
