1、控制器分组

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 新建 controller/admin/NewsController.go

package admin

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

type NewsController struct {
}

func (c NewsController) Index(ctx *gin.Context) {
    ctx.String(http.StatusOK, "新闻首页")
}

新建 controller/admin/UserController.go

package admin

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

type UserController struct {
}

func (u UserController) Index(ctx *gin.Context) {
    ctx.String(http.StatusOK, "这是用户首页")
}

func (u UserController) Add(ctx *gin.Context) {
    ctx.String(http.StatusOK, "增加用户")
}

......

配置对应的路由 -- adminRoutes.go

其他路由的配置方法类似

package routes

import (
    "github.com/gin-gonic/gin"
    "test4/controller/admin"
)

func AdminRoutesInit(router *gin.Engine) {
    adminRouter := router.Group("/admin")
    {
       adminRouter.GET("/user", admin.UserController{}.Index)
       adminRouter.GET("/user/add", admin.UserController{}.Add)
       adminRouter.GET("/news", admin.NewsController{}.Index)
    }
}

效果：

2、控制器的继承

1、新建 controller/admin/BaseController.go

package admin

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

type BaseController struct {
}

func (c BaseController) Success(ctx *gin.Context) {
    ctx.String(http.StatusOK, "成功")
}

func (c BaseController) Error(ctx *gin.Context) {
    ctx.String(http.StatusOK, "失败")
}

2、NewsController 继承 BaseController，继承后就可以调用控制器里面的公共方法了

package admin

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

type NewsController struct {
    BaseController
}

func (c NewsController) Index(ctx *gin.Context) {
    c.Success(ctx)
}
