beego框架简介

路由配置

• 普通路由

  $ vi ./myproj/routers/router.go

  package routers
  
  import (
      "myproj/controllers"
      "github.com/astaxie/beego"
  )
  
  func init() {
      beego.Router("/", &controllers.MainController{})
      beego.Router("/hello", &controllers.MainController{}) // 新增一条路由 /hello
  }

  $ curl http://127.0.0.1:8080/hello       
  
  
  
  
    
    
    ........

• namespace 路由

  // ./myproj/routers/router.go
  package routers
  
  import (
      "myproj/controllers"
      "github.com/astaxie/beego"
  )
  
  func init() {
      beego.Router("/", &controllers.MainController{})
      // 普通路由
      beego.Router("/hello", &controllers.MainController{})
      
      // namespace路由  
      ns := beego.NewNamespace("/api",
          beego.NSRouter("/hello1", &controllers.MainController{}),
          beego.NSRouter("/hello2", &controllers.MainController{}),
      )
      beego.AddNamespace(ns)
  }

  $ curl http://127.0.0.1:8080/api/hello1
  
  
  
  
    
    
    ........
    
  $ curl http://127.0.0.1:8080/api/hello2
  
  
  
  
    
    
    ........

控制器函数

• 重写MainController的Get方法

  // ./myproj/controllers/default.go
  package controllers
  
  import (
      "github.com/astaxie/beego"
  )
  
  type MainController struct {
      beego.Controller
  }
  
  func (c *MainController) Get() {
      // c.Data["Website"] = "beego.me"
      // c.Data["Email"] = "[email protected]"
      // c.TplName = "index.tpl"
  
      ret := map[string]string{
          "data": "hello golang!",
      }
      c.Data["json"] = ret
      c.ServeJSON()
  }

  $ curl http://127.0.0.1:8080/hello
  {
    "data": "hello golang!"
  }

ORM

• 基本流程

  建立 Model 相关的 struct
  使用 orm.RegisterModel 注册定义的 Model
  使用 orm.RefisterDriver 函数注册数据库驱动
  使用 orm.RegisterDataBase 函数绑定相关的数据库
  使用 orm.Debug 开启 ORM 调试模式（开发过程可以打开，release 需要关闭）

• 建立Model

  $ touch ./models/models.go

  // models.go
