Gin路由组

Gin路由组

接收任意请求的路由

• 区别于以往的GET()函数只能处理一种请求,Any()函数可以处理各种函数

• 语法: func (group *RouterGroup) Any(relativePath string, handlers ...HandlerFunc){}

• 案例:

  //可以接收任意请求的函数r.Any("/index", func(c *gin.Context) {switch c.Request.Method { case http.MethodGet:c.JSON(http.StatusOK, gin.H{"status": "Get",})case http.MethodPost:c.JSON(http.StatusOK, gin.H{"status": "Post",})}})

接收没有被定义的路由

• 用于处理各种没有被定义的路由

• 语法: func (engine *Engine) NoRoute(handlers ...HandlerFunc) {}

• 案例:

  //用于处理各种没有定义的路由被用户访问后显示的内容r.NoRoute(func(c *gin.Context) {c.HTML(http.StatusOK, "Not.html", gin.H{"email": "[e-mail]",})})

路由组

• 顾名思义,所谓路由组指的就是路由的组,也就是可以对路由进行分组管理的用法

• 语法: func (group *RouterGroup) Group(relativePath string, handlers ...HandlerFunc) *RouterGroup {}

• 案例:

  	//路由组(方便管理同一组的各种请求indexGroup := r.Group("/index"){//  index/nameindexGroup.GET("/name", func(c *gin.Context) {c.JSON(http.StatusOK, gin.H{"status": "name ok",})})// index/ageindexGroup.POST("/age", func(c *gin.Context) {c.JSON(http.StatusOK, gin.H{"status": "age ok",})})}
  

• 路由组嵌套(也就是在路由组中在添加一个路由组)

• 案例:

  //路由组(方便管理同一组的各种请求indexGroup := r.Group("/index"){//  index/nameindexGroup.GET("/name", func(c *gin.Context) {c.JSON(http.StatusOK, gin.H{"status": "name ok",})})// index/ageindexGroup.POST("/age", func(c *gin.Context) {c.JSON(http.StatusOK, gin.H{"status": "age ok",})})//嵌套路由组ageGroup := indexGroup.Group("/age"){// /index/age/dogageGroup.GET("/dog", func(c *gin.Context) {c.JSON(http.StatusOK, gin.H{"status": "dog ok",})})}}
