我正在尝试通过 grpc 从 vue 应用程序调用 go 应用程序,如下所示:

在此处输入图像描述

在它们之间,它是一个特使代理并且是必要的,如此处所述https://github.com/grpc/grpc-web#2-run-the-server-and-proxy。envoy 代理在 docker 容器、本地主机上的 vue 和 go 应用程序中运行。问题是,vue 应用程序无法访问 go 应用程序,因为我认为 envoy 运行在与 go 应用程序不同的网络上。Envoy 配置如下:

admin:
  access_log_path: /tmp/admin_access.log
  address:
    socket_address: { address: 0.0.0.0, port_value: 9901 }

static_resources:
  listeners:
  - name: listener_0
    address:
      socket_address: { address: 0.0.0.0, port_value: 9000 }
    filter_chains:
    - filters:
      - name: envoy.http_connection_manager
        config:
          codec_type: auto
          stat_prefix: ingress_http
          route_config:
            name: local_route
            virtual_hosts:
            - name: local_service
              domains: ["*"]
              routes:
              - match: { prefix: "/" }
                route:
                  cluster: identity_service
                  max_grpc_timeout: 0s
              cors:
                allow_origin_string_match:
                - prefix: "*"
                allow_methods: GET, PUT, DELETE, POST, OPTIONS
                allow_headers: keep-alive,user-agent,cache-control,content-type,content-transfer-encoding,custom-header-1,x-accept-content-transfer-encoding,x-accept-response-streaming,x-user-agent,x-grpc-web,grpc-timeout
                max_age: "1728000"
                expose_headers: custom-header-1,grpc-status,grpc-message
          http_filters:
          - name: envoy.grpc_web
          - name: envoy.cors
          - name: envoy.router
  clusters:
  - name: identity_service
    connect_timeout: 0.25s
    type: logical_dns
    http2_protocol_options: {}
    lb_policy: round_robin
    hosts: [{ socket_address: { address: 0.0.0.0, port_value: 9090 }}]   

envoy 配置有什么问题?
