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?
