Gin自定义控制器

自定义控制器

　　当我们的项目比较大的时候有必要对我们的控制器进行分组,我们采用MVC架构，自定义C层controller，控制器

　　目录结构

 　　main.go

package main

import (
	"gin_test/routers"
	"github.com/gin-gonic/gin"
)

func main() {
	r := gin.Default()
	routers.LoadGoodsRouters(r)
	routers.LoadOrderRouters(r)
	routers.LoadUserRouters(r)
	r.Run()
}

　　routers/goods.go

package routers

import (
	"gin_test/controllers/good"
	"github.com/gin-gonic/gin"

)

func LoadGoodsRouters(r *gin.Engine) {
	r1 := r.Group("/good")
	{
		r1.GET("/", good.GoodController{}.GoodHandler)
		r1.GET("/goodlist", good.GoodController{}.GoodlistHandler)
		r1.GET("/updategood",good.GoodController{}.UpdategoodHandler)
	}
}

　　routers/order.go

package routers

import (
   "gin_test/controllers/order"
   "github.com/gin-gonic/gin"
)

func LoadOrderRouters(r *gin.Engine)  {
   r1 := r.Group("/oOder")
   {
      r1.GET("/", order.OrderController{}.OrderHandler)
      r1.GET("/orderlist", order.OrderController{}.OrderlistHandler)
      r1.GET("/updateorder", order.OrderController{}.OpdateorderHandler)
   }
}

　　routers/user.go

package routers

import (
   "gin_test/controllers/user"
   "github.com/gin-gonic/gin"
)

func LoadUserRouters(r *gin.Engine) {
   r1 := r.Group("/user")
   {
      r1.GET("/", user.UserController{}.UserHandler)
      r1.GET("/userlist", user.UserController{}.UserlistHandler)
      r1.GET("/updateuser", user.UserController{}.UpdateuserHandler)
   }
}

　　controllers/good/good_controller

package good

import (
	"github.com/gin-gonic/gin"
	"net/http"
)
// 定义一个GoodController结构体
type GoodController struct {
}


// 把如下方法绑定给GoodController结构体
func (g GoodController)GoodHandler(c *gin.Context) {
	c.JSON(http.StatusOK, gin.H{
		"msg": "www.liuqingzheng.top",
	})
}

func (g GoodController)GoodlistHandler(c *gin.Context) {
	c.String(http.StatusOK, "goodlistHandler")
}
func (g GoodController)UpdategoodHandler(c *gin.Context) {
	c.String(http.StatusOK, "updategoodHandler")
}

　　controllers/order/order_controller

package order

import (
	"github.com/gin-gonic/gin"
	"net/http"
)
// 定义一个OrderController结构体
type OrderController struct {
}


// 把如下方法绑定给OrderController结构体
func (o OrderController)OrderHandler(c *gin.Context) {
	c.JSON(http.StatusOK, gin.H{
		"msg": "www.liuqingzheng.top",
	})
}

func (o OrderController)OrderlistHandler(c *gin.Context) {
	c.String(http.StatusOK, "orderlistHandler")
}
func (o OrderController)OpdateorderHandler(c *gin.Context) {
	c.String(http.StatusOK, "updateorderHandler")
}

　　controllers/user/user_controller

package user

import (
	"github.com/gin-gonic/gin"
	"net/http"
)
// 定义一个UserController结构体
type UserController struct {
}


// 把如下方法绑定给UserController结构体

func (u UserController)UserHandler(c *gin.Context) {
	c.JSON(http.StatusOK, gin.H{
		"msg": "www.liuqingzheng.top",
	})
}

func (u UserController)UserlistHandler(c *gin.Context) {
	c.String(http.StatusOK, "userlistHandler")
}
func (u UserController)UpdateuserHandler(c *gin.Context) {
	c.String(http.StatusOK, "updateuserHandler")
}

控制器继承

　　目录结构

 　　controllers/good/base_controller

package good

import "github.com/gin-gonic/gin"

type BaseController struct {

}

func (b BaseController)Success(c *gin.Context)  {
	c.String(200,"商品成功")
}
func (b BaseController)Error(c *gin.Context)  {
	c.String(200,"商品失败")
}

　　controllers/good/good_controller

package good

import (
	"github.com/gin-gonic/gin"
	"net/http"
)
// 定义一个GoodController结构体
type GoodController struct {
	BaseController  // 继承BaseController
}


// 把如下方法绑定给GoodController结构体
func (g GoodController)GoodHandler(c *gin.Context) {
	c.JSON(http.StatusOK, gin.H{
		"msg": "www.liuqingzheng.top",
	})
}

func (g GoodController)GoodlistHandler(c *gin.Context) {
	g.Success(c) // 使用继承的方法
}
func (g GoodController)UpdategoodHandler(c *gin.Context) {
	c.String(http.StatusOK, "updategoodHandler")
}
