前言

go-zero 是一個集成了各種工程實踐的 web 和 rpc 框架，通過彈性設計保障了大并發服務端的穩定性，經受了充分的實戰檢驗，

go-zero 包含極簡的 API 定義和生成工具 goctl，可以根據定義的 api 檔案一鍵生成 Go, iOS, Android, Kotlin, Dart, TypeScript, JavaScript 代碼，并可直接運行，

這么牛，怎么不想去試一下？！

go語言環境搭建

配置GO語言環境

新增go的代理 GOPROXY=https://goproxy.io,direct,https://mirrors.aliyun.com/goproxy/,https://goproxy.cn,https://athens.azurefd.net,https://gonexus.dev

設定環境變數

環境變數path中添加%GOROOT%\bin;%GOPATH%\bin

在vscode的配置

安裝插件

關鍵是go語言環境在vscode的配置，如下：

玩goctl工具

goctl是go-zero微服務框架下的代碼生成工具，其可以快速提升開發效率，讓開發人員將時間重點放在業務coding上……

查詢很多資料都不說的，不清晰，總是報command not found: goctl錯誤，

我也是將goctl工具安裝到$GOPATH/bin目錄下

環境變數也配置了，最后發現，所有網上博客都沒有說，把$GOPATH/bin，加入系統環境path變數，加入以后，重啟電腦，就可以正常使用goctl工具，

接下來，就是體驗goctl工具，
