1.安装完之后，会自动添加一个GOROOT环境变量，指向的就是go的安装目录，这样就能在各个路径执行go命令
2.安装完之后需要自己添加GOPATH环境变量，指向自己的项目目录，这样就能执行这个位置的代码，还有下载的包也会默认导入到这个目录下。
3.go get github.....从github上拉去包 如：go get -v github.com/spf13/cobra/cobra
4.设置环境变量 set GOPATH=E:/go_test查看当前环境变量：echo %GOPATH%
5.sublime 调试 go, 把编译系统选项设置为go， ctrl+shift+p 安装golang，Preferences->按键绑定-用户，加入{ "keys": ["f5"], "command": "build", "args": {"variant": "Run"} }（可参照按键绑定默认）然后就可以f5调试了。
6.git bash模拟post请求，curl -d "a=1" "http://localhost:8080"，不加-d是get请求
7.go语言部署到不同服务器方式：
64位系统：
linux
GOOS=linux GOARCH=amd64 go build -ldflags "-w -s" -o web；
windows
GOOS=windows GOARCH=amd64 go build -ldflags "-w -s" -o web；
mac
GOOS=darwin GOARCH=amd64 go build -ldflags "-w -s" -o web
8.如果报权限不够，那么先对文件执行chmod -R 777：比如：
vscode 先装一个vscode的go插件然后在gopath/bin内安装一堆github的东西配置go：
