	v1.GET("hello", func(c *gin.Context) {
		fmt.Println("helloword")
	})

	v1.POST("post", func(c *gin.Context) {
		request := requests.Params{}//获取结构体里的参数实例
		requestResult := requests.Validator(&request, c)//验证
		if requestResult != nil {
			c.JSON(http.StatusOK, gin.H{
				"msg": requestResult.Error(),
			})
			return
		}
		c.JSON(http.StatusOK, "succes")
	})
}
