goctl quickstart

概述

goctl quickstart 用于快速生成 api、rpc 服务并启动，可以帮助初入 go-zero 的开发者快速上手，开发者在 demo 启动并访问成功后，可以阅读源码简单的了解服务目录结构，go-zero 工程结构，以此来对 go-zero 有个大致的了解。

goctl quickstart 指令

  1. $ goctl quickstart --help
  2. quickly start a project
  4. Usage:
  5.   goctl quickstart [flags]
  7. Flags:
  8.   -h, --help                  help for quickstart
  9.   -t, --service-type string   specify the service type, supported values: [mono, micro] (default "mono")

service-typestringNOmono生成 demo 服务类型，mono：单体服务，micro：微服务

使用示例

  • 生成单体服务
  • 生成微服务

如果选择 mono 类型，goctl 会生成一个最小化的 HTTP 服务，然后启动 HTTP 服务。

  1. 快速生成服务
  1. # 进入用户 Home 目录
  2. $ cd ~
  4. # 创建目录
  5. $ mkdir quickstart && cd quickstart
  7. # 生成单体服务
  8. $ goctl quickstart --service-type mono
  9. go: creating new go.mod: module greet
  10. >> Generating quickstart api project...
  11. Done.
  12. >> go mod tidy

如果选择 micro 类型，goctl 会生成一个 gRPC 服务和一个 HTTP 服务，然后启动 gRPC 服务来和 HTTP 服务进行通讯。

  1. 快速生成服务
  1. # 进入用户 Home 目录
  2. $ cd ~
  4. # 创建目录
  5. $ mkdir quickstart && cd quickstart
  7. # 生成单体服务
  8. $ goctl quickstart --service-type micro
