go导入“github.com/go-sql-driver/mysql“连接失败错误解决

在使用golang连接mysql数据库时需要用到go的数据库连接驱动

github.com/go-sql-driver/mysql

• 首先需要在golang的终端输入

go get -u github.com/go-sql-driver/mysql

可能会出现如下错误

PS E:\Go\practice\PRO1> go get -u github.com/go-sql-driver/mysql
go: module github.com/go-sql-driver/mysql: Get "https://proxy.golang.org/github.com/go-sql-driver/mysql/@v/list": dial tcp 142.251.42.241:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

• 这是因为无法对外网进行访问（开了VPN也不行），可以通过输入一下命令进入代理网站进行访问

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

• 该结果无返回，然后再输入上述命令

go get -u github.com/go-sql-driver/mysql

• 可以看到已经安装的版本号了

PS E:\Go\practice\PRO1> go get -u github.com/go-sql-driver/mysql   
go: downloading github.com/go-sql-driver/mysql v1.6.0
go: added github.com/go-sql-driver/mysql v1.6.0
