Express网关无法获取

Question

I am trying to setup multiple (nodejs) services in express gateway, but, for some reason, the second service is not picked up. Please find below my gateway.config.yml

http:
  port: 8080
admin:
  port: 9876
  hostname: localhost
apiEndpoints:
  config:
    host: localhost
  actions:
    host: localhost
serviceEndpoints:
  configService:
    url: "http://localhost:3002"
  actionService:
    url: "http://localhost:3006"
policies:
- basic-auth
- cors
- expression
- key-auth
- log
- oauth2
- proxy
- rate-limit
pipelines:
  - name: basic
    apiEndpoints:
    - config
    policies:
    - proxy:
      - action:
          serviceEndpoint: configService
          changeOrigin: true
  - name: basic2
    apiEndpoints:
    - actions
    policies:
    - proxy:
      - action:
          serviceEndpoint: actionService
          changeOrigin: true

Answer 1

That is expected, because apiEndpoints config part uses the same host and path to build routing

apiEndpoints:
  config:
    host: localhost
  actions:
    host: localhost

what you can do is to somehow separate it by path

apiEndpoints:
  config:
    path: /configs
  actions:
    path: /actions

in that way localhost/configs/db will go to config service ..:3002/configs/db and localhost/actions/magic will go to actions ..:3006/actions/magic

you may also want to install Rewrite plugin https://www.express-gateway.io/docs/policies/rewrite/

in case target services have different URL patterns
