## 一、Put ##

修改 goods.go：

package controllers
    
    import (
    	"github.com/astaxie/beego"
    )
    
    type GoodsController struct {   // 首字母要大写
    	beego.Controller
    }
    
    func (c *GoodsController) Get() {   // get
    	c.Data["title"] = "你好beego"
    	c.TplName = "goods.tpl"
    }
    
    func (c *GoodsController) DoAdd() {   // post
    	c.Ctx.WriteString("执行增加操作")
    }
    
    func (c *GoodsController) DoEdit() {   // put
    	c.Ctx.WriteString("执行修改操作")
    }
    
    func (c *GoodsController) DoDelete() {   // delete
    	c.Ctx.WriteString("执行删除操作")
    }

在 router.go 中添加路由：

package routers
    
    import (
    	"beegodemo/controllers"
    	"github.com/astaxie/beego"
    )
    
    func init() { 
        beego.Router("/", &controllers.MainController{ })
    
    	beego.Router("/article", &controllers.ArticleController{ })  // 访问 Get 方法
    	beego.Router("/article/add", &controllers.ArticleController{ }, "get:AddArticle")  // 访问自定义方法
    	beego.Router("/article/edit", &controllers.ArticleController{ }, "get:EditArticle")  // 结构体地址
    
    	beego.Router("/user", &controllers.UserController{ })
    	beego.Router("/user/add", &controllers.UserController{ }, "get:AddUser")  // 结构体地址
    	beego.Router("/user/doAdd", &controllers.UserController{ }, "post:DoAddUser")
    	beego.Router("/user/edit", &controllers.UserController{ }, "get:EditUser")  // 结构体地址
    	beego.Router("/user/doEdit", &controllers.UserController{ }, "post:DoEditUser")
    	beego.Router("/user/getUser", &controllers.UserController{ }, "get:GetUser")  // 首字母大写
    
    	beego.Router("/goods", &controllers.GoodsController{ })
    	beego.Router("/goods/add", &controllers.GoodsController{ }, "post:DoAdd")
    	beego.Router("/goods/edit", &controllers.GoodsController{ }, "put:DoEdit")
    	beego.Router("/goods/delete", &controllers.GoodsController{ }, "delete:DoDelete")
    
    }

使用 Postman 来测试接口：

## 二、Delete ##

goods.go：

package controllers
    
    import (
    	"github.com/astaxie/beego"
    	"strconv"
    )
    
    type GoodsController struct {   // 首字母要大写
    	beego.Controller
    }
    
    func (c *GoodsController) Get() {   // get
    	c.Data["title"] = "你好beego"
    	c.TplName = "goods.tpl"
    }
    
    func (c *GoodsController) DoAdd() {   // post
    	c.Ctx.WriteString("执行增加操作")
    }
    
    func (c *GoodsController) DoEdit() {   // put
    	title := c.GetString("title")
    	c.Ctx.WriteString("执行修改操作--" + title)
    }
    
    func (c *GoodsController) DoDelete() {   // delete
    	id, err := c.GetInt("id")
    	if err != nil { 
    		c.Ctx.WriteString("参数错误")
    	}
    	c.Ctx.WriteString("执行删除操作--" + strconv.Itoa(id))
    }

router.go：

在 Postman 中在 Body 中输入 Key 和 Value，点击 Send，可以看到：

同样的，edit 也是：
