Prepare Dubbo Service

Start zookeeper, ensure docker and compose are prepared in advance. If available locally, this can be ignored.

docker-compose.yml

  1. docker-compose -f {CURRENT_PATH}/dubbo-go-pixiu-samples/dubbohttpproxy/docker/docker-compose.yml && docker-compose up -d

Start Dubbo Server

Run

  1. export DUBBO_GO_CONFIG_PATH={CURRENT_PATH}/dubbo-go-pixiu-samples/dubbohttpproxy/server/dubbo/profiles/dev/server.yml
  2. go run .

Start Pixiu

  1. ./dubbo-go-pixiu gateway start --config {CURRENT_PATH}pixiu/conf.yaml

Use curl for querying and updating

Run the following curl command:

Query

  1. curl http://localhost:8888/UserService/com.dubbogo.pixiu.UserService/GetUserByName -X POST \
  2.   -H 'Content-Type: application/json' \
  3.   -H 'x-dubbo-http1.1-dubbo-version: 1.0.0' \
  4.   -H 'x-dubbo-service-protocol: dubbo' \
  5.   -H 'x-dubbo-service-version: 1.0.0' \
  6.   -H 'x-dubbo-service-group: test' \
  7.   -d '{"types":"string","values":"tc"}'

Update

  1. curl http://localhost:8888/UserService/com.dubbogo.pixiu.UserService/UpdateUserByName -X POST \
  2.   -H 'Content-Type: application/json' \
  3.   -H 'x-dubbo-http1.1-dubbo-version: 1.0.0' \
  4.   -H 'x-dubbo-service-protocol: dubbo' \
  5.   -H 'x-dubbo-service-version: 1.0.0' \
  6.   -H 'x-dubbo-service-group: test' \
  7.   -d '{"types":"string,object","values":["tc",{"id":"0001","code":1,"name":"tc","age":15}]}'
