Configure the go locale

First of all, you need to configure the Go language environment. Read this article for details: Go language installation and its environment configuration

install git

You can visit https://git-scm.com/ to download related software.
Once downloaded, you can simply double-click to install it.
If you need to execute the go get command in the cmd window, you must first install the git environment.

set go agent

In order to solve the problem that github may not be accessible or the access speed may be slow when downloading the gin framework, we need to configure the public proxy image of go in the cmd window. Please execute the following command:

go env -w GOPROXY=https://goproxy.io,direct

as shown in the picture

With this set up, our go command will quickly pull code from the public proxy mirror.

Download the gin framework

Execute the command in the cmd window:

go get -u github.com/gin-gonic/gin

But it should be noted that the latest version of Gin must be downloaded from the terminal with the go.mod file.

After the download is complete, the downloaded related files can appear in the library directory of the previous GOPATH.

It should be noted that in the go language, it is not possible to name the project as go, otherwise an error will be reported in this go.mod.

So just need to recreate it

After running the command again, it was found that no error was reported.

Test code:

package main

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

func main() {
    
    
	router := gin.Default()
	router.GET("/", func(c *gin.Context) {
    
    
		c.String(http.StatusOK, "Hello！欢迎来到GO世界！")
	})
	// 默认端口是8080,也可以指定端口 r.Run(":80")
	router.Run()
}

run successfully
