go下载地址有需要的童鞋请自行下载
执行一下命令建立新项目，生成go.mod文件

go mod init learnGo

修改go.mod增加依赖包

module learnGo

go 1.13

PS 不懂科学上网的同学可以把需要的依赖加到 replace（）里面。require 里面引入你需要的依赖库

require (
    github.com/dgrijalva/jwt-go v3.2.0+incompatible
    github.com/gin-gonic/gin v1.4.0
    github.com/go-playground/locales v0.12.1 // indirect
    github.com/go-playground/universal-translator v0.16.0 // indirect
    github.com/go-sql-driver/mysql v1.4.1
    github.com/jinzhu/gorm v1.9.11
    github.com/kr/pretty v0.1.0 // indirect
    github.com/leodido/go-urn v1.1.0 // indirect
    gopkg.in/go-playground/validator.v9 v9.30.0
)

下载依赖文件

go mod  download

执行命令将依赖的文件拷贝到项目相面

go mod  vendor

新建main.go

package main

import (
    "github.com/gin-gonic/gin"
)

func main() {
    router := gin.Default()
    router.GET("/", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "ping",
        })
    })

    _ = router.Run(":8089")
}

最终项目结构如下

执行命令，启动服务

go run main.go

访问http://127.0.0.1:8089/，输出{"message":"ping"}说明我们的gin框架成功运行起来
