`RewritePath` `GatewayFilter` Factory

“RewritePath” “GatewayFilter” 工厂采用路径 “regexp” 参数和 “replacement” 参数。这使用 Java 正则表达式对请求路径进行灵活改写。以下列表配置了一个 “RewritePath” “GatewayFilter”：

The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. This uses Java regular expressions for a flexible way to rewrite the request path. The following listing configures a RewritePath GatewayFilter:

application.yml

spring:
  cloud:
    gateway:
      routes:
      - id: rewritepath_route
        uri: https://example.org
        predicates:
        - Path=/red/**
        filters:
        - RewritePath=/red/?(?<segment>.*), /$\{segment}

对于请求路径 “/red/blue”，这在发出向下请求之前将路径设置到 “/blue”。请注意，“$” 应替换为 “$\” ，这是由于 YAML 规范。

For a request path of /red/blue, this sets the path to /blue before making the downstream request. Note that the $ should be replaced with $\ because of the YAML specification.
