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. Easy to extend and/or customize using standard Spring patterns status: The HTTP status of the request returned to the client. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. You can combine multiple route predicate factories with logical and statements. If the fallback is called, the request is forwarded to the controller matched by the URI. The Host route predicate factory takes one parameter: a list of host name patterns. 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 default is http|https|ftp|ftps. 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. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. In future milestone releases, there will be some KeyResolver implementations. This uses Java regular expressions for a flexible way to rewrite the request path. The default list of headers that is removed comes from the IETF. 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 RequestHeaderSize GatewayFilter factory takes maxSize and errorHeaderName parameters. A Token Relay is where an OAuth2 consumer acts as a Client and Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. 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. It must be a valid Spring HttpStatus. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. Both offer the same possibilities. 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. In 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. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. The RemoteAddr Route Predicate Factory, 5.10.1. return routeBuilder.routes() The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The circuit breaker config object takes a list of The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. You can configure Spring Cloud Gateway for Kubernetes to run multiple instances in High Availability as you would do with a normal Kubernetes resource. Server. backoff: The configured exponential backoff for the retries. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. 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. 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 example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. For relative redirects, you should use uri: no://op as the uri of your route definition. Otherwise, the original value in the client request is sent. Because Spring-Cloud-Gateway is a responsive architecture design based on WebFlux, traditional programming ideas are not suitable for the development of Reactor Stream in the process of migrating from Zuul. 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. XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. 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. 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. As a result, you can inject request headers and query parameters, for instance, and you can constrain the incoming requests with declarations in the mapping annotation. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. You must use $\ to mean $ because of the YAML specification. 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. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. essentially skipping the filter. The following describes an alternative style gateway. 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 This is the number of tokens taken from the bucket for each request and defaults to 1. Since the request can be read only once, we need to cache the request body. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. 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. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. Tripping The Circuit Breaker On Status Codes, 12.4.1. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. 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. Naming Custom Filters And References In Configuration, 18. SetResponseHeader is aware of URI variables used to match a path or host. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. Creating and Deleting a Particular Route, 15.8. 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. 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 shows such an errorMessage: There are certain situation when the host header may need to be overridden. Like in the case of global configuration, the properties belong to Spring Framework CorsConfiguration. Cleanliness 4.4. Spring Cloud Zuul is one of the core components of Spring Cloud Netflix subproject. First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. 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 accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. 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. Retrieving the Routes Defined in the Gateway, 15.5. It is possible to create a gateway filter named without the. The input type is a Spring Framework ServerWebExchange. Spring Cloud Gateway - read response body and set response headers Ask Question Asked 1 year, 11 months ago Modified 1 year, 11 months ago Viewed 675 times 0 I want to implement a GatewayFilter that reads the response body and out of this the response code is determined and should then be set afterwards. Predicate: This is a Java 8 Function Predicate. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). 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. This vulnerability is known as HTTP Response Splitting. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. Policy to specify how to modify the response code, body and headers. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The PreserveHostHeader GatewayFilter factory has no parameters. .uri("http://someuri") The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. GatewaySampleApplication.java. 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). The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). 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. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. Generally, it will put the identity information into the request header and will not modify the content of the request and response. 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. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. 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). It runs after all other filters have completed and writes the proxy response back to the gateway client response. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. Spring Cloud Gateway Encryption/Decryption of Request/Response | by Sumant Rana | Level Up Coding Write Sign up Sign In 500 Apologies, but something went wrong on our end. value or the String representation of the HttpStatus enumeration. 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 The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). This interface and its usage are subject to change in future milestone releases. Code Revisions 1 Stars 14 Forks 3. application.yml. 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. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. 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). Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. *) and the replacement /${remaining}. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Spring Cloud Gateway 4.0.3 This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. 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. This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. Am I doing it wrong? It is the name of the query parameter to be removed. The maxSize parameter is the maximum data size allowed by the request header (including key and value). The name and argument names are listed as code in the first sentence or two of each section. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. 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. }) You can enable, disable, or configure policies to control how they modify APIcast. status codes that if returned will cause the circuit breaker to be tripped. 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. If You Appreciate This, You Can Consider: We are thankful for your never ending support. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. . If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). The AddRequestHeader GatewayFilter factory takes a name and value parameter. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. It uses the Host header, scheme, port and path of the current request to create the various headers. . 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. .metadata(RESPONSE_TIMEOUT_ATTR, 200) It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. 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_IN_REQUEST: The version is stripped only if the original request path contains no version. The collection of filters applied to the route. 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). The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. The lowercase full name of the secure header needs to be used to disable it.. To configure per-route timeouts: Configuring Predicates and Filters For, 15.4. Already on GitHub? The XForwarded Remote Addr Route Predicate Factory, 6.5.1. Note that the $ should be replaced with $\ because of the YAML specification. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. 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. .metadata(CONNECT_TIMEOUT_ATTR, 200); @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? None of the prior documentation applies to what follows. I think i have to go for a blocking call here. There is an abstract class called AbstractRoutePredicateFactory which you can extend. 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). This section covers common problems that may arise when you use Spring Cloud Gateway. Star 14. This predicate matches requests that happen before the specified datetime. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. 2016-10-05: 4.3: CVE-2016-6426 CISCO If youre using load-balanced routes, you need to explicitly define your. All of these predicates match on different attributes of the HTTP request. connect-timeout must be specified in milliseconds. Then the proxy request is made. It must be a Java System Property, not a Spring Boot property. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. /resource). spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} This can be used with reverse proxies such as load balancers or web application firewalls where 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. 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. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. Zuul profile. When setting the 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. A per-route response-timeout with a negative value will disable the global response-timeout value. 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. Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. Easy to extend and/or customize using standard Spring patterns 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) This metric will be available from /actuator/metrics/spring.cloud.gateway.routes.count. }, 4. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. AddResponseHeader is aware of URI variables used to match a path or host. It is the name of the header to be removed. 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. Spring cloud gateway response body modification. Displays information about a particular route. 1050. This predicate extracts the URI template variables (such as segment, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. . The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). 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). The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. Add a response header named X-Request-Foo with a value of Bar to the original response. 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. Spring Cloud Gateway includes many built-in GatewayFilter Factories. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). Well occasionally send you account related emails. For more detailed examples of how to use any of the following filters, take a look at the. 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 following listing configures a redis-rate-limiter: Rate limits below 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds, and burstCapacity to the product of replenishRate and requestedTokens. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73.
