安装gin框架(使用mod,makefile方式)

1 新建一个项目目录

 mkdir wages_service

2 新建Makefile文件

touch Makefile

文件内容如下

all: clean deps

clean:
    @rm -rf go.mod
    @rm -rf go.sum
    @rm -rf vendor

deps:
    @echo "初始化模块"
    go mod init wages_service
    @echo "下载依赖"
    export GOPROXY=http://goproxy.io
    go mod tidy -v
    @echo "检查依赖是否全部下载"
    go mod verify
    @echo "创建vendor"
    go mod vendor

3 新建main.go文件

package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
    "time"
)

func main() {
    r := gin.Default()
    r.GET("/test", func(c *gin.Context) {
        data := map[string]interface{}{
            "lang": "golang",
        }
        c.AsciiJSON(http.StatusOK, data)
    })

    s := &http.Server{
        Addr:           ":9000",
        Handler:        r,
        ReadTimeout:    30 * time.Second,
        WriteTimeout:   30 * time.Second,
        MaxHeaderBytes: 1 << 20,
    }
    s.ListenAndServe()
}

4 执行命令

安装依赖包

make all

初始化模块
go mod init wages_service
go: creating new go.mod: module wages_service
初始化模块结束
下载依赖
export GOPROXY=http://goproxy.io
go mod tidy
go mod vendor
下载依赖结束

5 启动服务

go run main.go 

[GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached.

[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
 - using env:   export GIN_MODE=release
 - using code:  gin.SetMode(gin.ReleaseMode)
