golang go get命令无响应问题

操作

现象

go get github.com/golang/net: module github.com/golang/net: 
Get https://proxy.golang.org/github.com/golang/net/@v/list: 
dial tcp 216.58.220.209:443: 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.

原因

所下载的库依赖有官方库，而官方被封禁网导致。

方法

法一：设置代理

法二：git clone 依赖包直接到GOPATH/src/下

go get 指令没有反应/出错/超时

使用GitHub上的eclipse/paho.mqtt.golang包时，长时间无响应后，弹出以下错误提示

package golang.org/x/net/proxy: unrecognized import path “golang.org/x/net/proxy” (https fetch: Get https://golang.org/x/net/proxy?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.)

出现这个问题的原因主要还是我们所使用网络的特殊性，导致go get无法拉取我们所需包的源码，从goproxy的官网上的使用分布图就能很明显的看出来：

此时修改一下环境变量启动GOPROXY，再用go get -v即可，-v参数能够显示go get执行的进度
