Envoy 代理不输出 http

问题描述

我有一个 gRPC 网络客户端，可在浏览器中运行。使用wireshark我没有看到来自envoy的输出Http包，但是看到来自浏览器的Http包

这里是 envoy.yaml

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

static_resources:
  listeners:
  - name: client
    address:
      socket_address: { address: 0.0.0.0,port_value: 8080 }
    filter_chains:
    - filters:
      - name: envoy.filters.network.http_connection_manager

              domains: ["*"]
              routes:
              - match: { prefix: "/" }
                route:
                  cluster: echo_service
                  max_stream_duration:
                    grpc_timeout_header_max: 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

          - name: envoy.filters.http.cors
          - name: envoy.filters.http.router
  clusters:
  - name: echo_service
    connect_timeout: 10s
    type: logical_dns
    http2_protocol_options: {}
    lb_policy: round_robin
    load_assignment:
      cluster_name: cluster_0
      endpoints:
        - lb_endpoints:
            - endpoint:
                address:
                  socket_address:
                    address: 192.168.7.20
                    port_value: 50005

我唯一看到的是保持活动包。可能是什么问题，那个特使没有路由我的包裹？我收到 504 错误
