StripPrefix
Filter
StripPrefix
过滤器使用一个参数 parts
。parts
参数指示在将请求发送到下游之前从请求中剥离路径中的部分数。以下列表配置了一个 StripPrefix
过滤器:
application.yml
spring:
cloud:
gateway:
mvc:
routes:
- id: nameRoot
uri: https://nameservice
predicates:
- Path=/name/**
filters:
- StripPrefix=2
GatewaySampleApplication.java
import static org.springframework.cloud.gateway.server.mvc.filter.BeforeFilterFunctions.stripPrefix;
import static org.springframework.cloud.gateway.server.mvc.handler.GatewayRouterFunctions.route;
import static org.springframework.cloud.gateway.server.mvc.handler.HandlerFunctions.http;
@Configuration
class RouteConfiguration {
@Bean
public RouterFunction<ServerResponse> gatewayRouterFunctionsStripPrefix() {
return route("nameRoot")
.GET("/name/**", http("https://example.org"))
.before(stripPrefix(2))
.build();
}
}
当通过网关向 /name/blue/red
发出请求时,向 nameService
发出的请求看上去就像 https://nameservice/red
。
