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並發服務端的穩定性，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 文件一鍵生成 Go, iOS, Android,
Kotlin, Dart, TypeScript, JavaScript 代碼，並可直接運行。

這麼牛，怎麼不想去試一下？！

go語言環境搭建

配置GO語言環境

新增go的代理

GOPROXY=//goproxy.io,direct,//mirrors.aliyun.com/goproxy/,//goproxy.cn,//athens.azurefd.net,//gonexus.dev
image

設置環境變量

環境變量path中添加 %GOROOT%\bin;%GOPATH%\bin
image

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

環境變量也配置了，最後發現，所有網上博客都沒有說，把 $GOPATH/bin，加入系統環境path變量。加入以後，重啟電腦，就可以正常使用goctl工具。

接下來，就是體驗goctl工具。

再另外開一個cmd窗口

D:\>cd D:\go-learn\greet

D:\go-learn\greet>goctl api java -api greet.api -dir greet

總結

除了goctl神器，go-zero還有很多的小工具。

  1. 流數據處理利器：fx。如java8的lambda,，go-zero也有了！fx.Filter().Sort().Head() ，讓數組的複雜處理變得簡單。
  2. List itemmapReduce降低服務相應時間：mr.Finish(), mr.Map().Reduce(), 跟並發處理waitGroup說拜拜。
  3. etcd服務發現的集成：p2c的算法發現服務，避免開發人員點對點或nginx的轉發服務，安裝一個etcd就完事了。
  4. jwt集成api：輕鬆擁有一個jwt的後台服務。
  5. 集成Prometheus：輕鬆擁有一個帶監控的golang後台服務。

Go語言主要用作服務器端開發，其定位是用來開發「大型軟件」的，適合於很多程序員一起開發大型軟件，並且開發周期長，支持雲計算的網絡服務。Go語言能夠讓程序員快速開發，並且在軟件不斷的增長過程中，它能讓程序員更容易地進行維護和修改。它融合了傳統編譯型語言的高效性和腳本語言的易用性和富於表達性。

Go語言作為服務器編程語言，很適合處理日誌、數據打包、虛擬機處理、文件系統、分佈式系統、數據庫代理等；網絡編程方面，Go語言廣泛應用於Web應用、API應用、下載應用等；除此之外，Go語言還可用於內存數據庫和雲平台領域，目前國外很多雲平台都是採用Go開發。
