前言

在开发go项目时经常会用到 golang.org/x下的包，但这个通常无法下载，例如：

go get golang.org/x/net: unrecognized import path "golang.org/x/net" (https fetch: Get https://golang.org/x/net?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.)

下载失败了！！
好不容易golang出了个go module可以不再依赖Gopath,现在包又下不了！！有没有说明解决办法呢？？？
有！！使用代理！
