1. 获取go-zero库

go get -u github.com/zeromicro/go-zero

2. 安装goctl

brew install goctl

goctl -v
#goctl version 1.5.4 darwin/amd64

3. 创建.api文件， greet.api

goctl api -o greet.api

syntax = "v1"

info (
	title: // TODO: add title
	desc: // TODO: add description
	author: "peng.chen"
	email: "chen_peng7@163.com"
)

type request {
	// TODO: add members here and delete this comment
}

type response {
	// TODO: add members here and delete this comment
}

service greet-api {
	@handler GetUser // TODO: set handler name and delete this comment
	get /users/id/:userId(request) returns(response)

	@handler CreateUser // TODO: set handler name and delete this comment
	post /users/create(request)
}

4. 生成服务端代码

goctl api go -api greet.api -dir greet

结构如下 

 

5.启动服务并运行

go run greet.go -f etc/greet-api.yaml
curl -i http://localhost:8888/users/id/111
