go moudle模块加载被墙解决方法
作者：互联网
go moudle 为golang的一种包管理方式；而对于在国内使用，很多外网的包可能会无法使用，遂做一个记录；
报错信息：
go: golang.org/x/crypto@v0.0.0-20190701094942-4def268fd1a4: unrecognized import path "golang.org/x/crypto" (https fetch: Get https://golang.org/x/crypto?go-get=1: dial tcp 216.239.37.1:443: 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.)

对于golang.org/x/**下的包，由于墙的原因，无法更新；解决方案如下：
方法1：
根据需要的版本号，如果不清楚，可以使用 v0.0.0 ，执行命令, 可以用github上的镜像地址替换：
go mod edit -require=golang.org/x/***@v0.0.0
go mod edit -replace=golang.org/x/***@v0.0.0=github.com/golang/***@latest
方法1设置后，go.mod文件中显示如下：
go 1.12
require golang.org/x/*** v0.0.0
replace golang.org/x/*** v0.0.0 => github.com/golang/*** latest
方法2：
配置代理地址：https://goproxy.io，在idea中可以直接配置go moudle的代理地址为这个url；
如果你使用的 Go 版本>=1.13, 你可以通过设置 GOPRIVATE 环境变量来控制哪些私有仓库和依赖(公司内部仓库)不通过 proxy 来拉取，直接走本地，设置如下：
go env -w GOPROXY=https://goproxy.io,direct
# 设置不走 proxy 的私有仓库，多个用逗号相隔
go env -w GOPRIVATE=*.corp.example.com
