二 :gin web框架学习常用路由参数解析

获取"/user/:name"的name参数

 router.GET("/user/:name", func(c *gin.Context) {
 name := c.Param("name")
 c.JSON(http.StatusOK,gin.H{"name":name})
 })

• curl http://127.0.0.1:9000/user/lcd
• 返回结果: {"name":lcd}

/params?firstname=lcd&lastname=dong

 router.GET("/params", func(context *gin.Context) {
 firstname := context.DefaultQuery("firstname","defaultName")
 lastname := context.Query("lastname")
 context.JSON(http.StatusOK,gin.H{
 "firstName":firstname,
 "lastName":lastname,
 })
 })
 

• /params?firstname=lcd&lastname=dong
• 返回结果: {"lastName",lin,"lastName":dong}
• 对于context.DefaultQuery(key,defaultValue): 如果没有指定字段,则给定key设置一个默认值,在分页

Multipart/Urlencoded Form

 router.POST("/form_post", func(c *gin.Context) {
 name := c.PostForm("name")
 nick := c.DefaultPostForm("age", "90")
 
 c.JSON(200, gin.H{
 "name": name,
 "age": nick,
 })
 })

Passwd string `form:"passwd" json:"passwd" bdinding:"required"`
Age int `form:"age" json:"age"`

}

router.POST("/json", func(context *gin.Context) {

 context.JSON(200,gin.H{"data":user})
 })
