vscode 配置 golang开发环境

如果你使用golang，那么强烈建议你采用vscode作为IDE。

1. 首先在vscode 当中安装go插件，如上图

2. 配置 %AppData%\Code\User\settings.json 当中的参数

go.goroot; go.toolsGopath 这两个参数一定要配置上

vscode配置有两种user,workspace

user是全局生效，针对所有项目

workspace仅针对当前项目，如果与user当中的配置不一样，在当前项目中使用workspace的配置

"go.formatTool": "goformat",
"go.goroot": "D:\\sdk\\go",
"go.toolsGopath": "D:\\sdk\\gotools",
"go.inferGopath": true,
"go.gotoSymbol.includeGoroot": true,
"go.gotoSymbol.includeImports": true, 
"go.useLanguageServer": true,
"go.autocompleteUnimportedPackages": true,
"go.coverOnTestPackage": false,

将上面的配置增加到 settings.json 当中，然后重启vscode

3. ctrl+shift+p 调出go的命令窗口，然后选择 Go: Install/Update tools

为什么一定要安装这些工具呢？

没有这些工具，代码导航、格式化等这些常用功能都不能用，开发的效率和体验会非常不好

4. 选中所有的工具后，点击OK按钮

5. 等待下载安装完成即可

国内特殊环境引起的，需要自行解决！
不过，在golang的最新版本中支持使用代理，使用方法如下

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

如果全部成功将显示下面的提示：
