如何在spring-cloud-gateway中为netty客户设置代理？

Question

（这样，从spring-cloud-gateway到下游服务的所有请求都将通过代理）

我指的是https://github.com/spring-cloud/spring-cloud-gateway/issues/176。

按照

为netty客户配置代理

spring:
  cloud:
    gateway:
      httpclient:
        connectTimeout: 5000
        proxy:
          host: test.proxy.local
          port: 8080

当呼叫spring-cloud-gateway时，希望该呼叫通过代理进行并进入配置的实际下游URL中。

当代理尝试连接时，出现以下错误

 i.n.handler.proxy.ProxyConnectException: http, none, test.proxy.local/172.18.199.200:8080 => api.cicd.ps.money:80, status: 403 Proxy denies fulfilling the request
