作者: adm 分类: go 发布时间: 2021-09-27 16:00

1.Install go
2.Generate go mod

go mod init

3.Add go chassis

go get github.com/go-chassis/go-chassis/v2@v2.0.2

4.Use go mod

GO111MODULE=on go mod download
#optional
GO111MODULE=on go mod vendor

if you are facing network issue
export GOPROXY=https://goproxy.io
5.Install service-center

案例代码

type RestFulHello struct {}

func (r *RestFulHello) SayHello(b *restful.Context) {

	b.Write([]byte("get user id: " + b.ReadPathParameter("userid")))
}
func (r *RestFulHello) SayHello1(b *restful.Context) {

	b.Write([]byte("get user id1: " + b.ReadPathParameter("userid")))
}
func (r *RestFulHello) URLPatterns() []restful.Route {
	return []restful.Route{
		{Method: http.MethodGet, Path: "/sayhello/{userid}", ResourceFunc: r.SayHello},
		{Method: http.MethodGet, Path: "/sayhello1/{userid}", ResourceFunc: r.SayHello1},
	}
}
func main() {
	// register struct
	chassis.RegisterSchema("rest", &RestFulHello{})
	//start all server you register in server/schemas.
	if err := chassis.Init(); err != nil {
		openlog.Error("Init failed. "+err.Error())
		return
	}
	chassis.Run()
}

chassis.yaml

servicecomb:
registry:
address: http://127.0.0.1:30100
protocols: # what kind of server you want to launch
rest: #launch a http server
listenAddress: 127.0.0.1:5001

microservice.yaml

servicecomb:
service:
name: RESTServer # name your provider
