Go的Gin框架学习-CFANZ编程社区

框架安装

1、设置代理
在下载gin框架之前，我们还需要配置go公共代理镜像，目的是解决github无法访问或者访问速度慢的问题，在cmd窗口中执行命令：

# 这里我设置成自动模式，on的模式我开启后莫名的无法执行gin代码下载
go env -w GO111MODULE=auto
# 设置代理
go env -w GOPROXY=https://goproxy.io,direct

2、下载gin框架

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

3、创建demo项目，运行gin框架

package main

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

func main() {
	router := gin.Default()

	router.GET("/", func(context *gin.Context) {
		context.String(http.StatusOK, "HelloWorld")
	})

	router.Run(":3333")
}

4、缺少包报错问题处理
由于网络原因，此处与google相关的包无法访问，需要单独下载

Compilation finished with exit code 1

1）在GOPATH目录的src目录下，新建文件夹google.golang.org，然后cmd窗口中，切换到该目录下，执行命令：
D:\go_work\src\github.com\google.golang.org

git clone https://github.com/protocolbuffers/protobuf-go.git

下载完成后，将protobuf-go目录重命名为protobuf

2）由于网络原因，此处与golang.org相关的包也无法下载
在GOPATH目录的src目录下，新建文件夹golang.org，然后cmd窗口中，切换到该目录下，执行命令：
D:\go_work\src\github.com\golang.org

git clone https://github.com/golang/tools.git

下载完成后，将tools目录重命名为x
在这里插入图片描述
3）进入x目录，继续执行命令：
D:\go_work\src\github.com\golang.org\x

git clone https://github.com/golang/crypto.git
