BindQuery does not work for binding:required fields

[mdnight]

• gin version: 1.3.0
• operating system: arch linux

Description

For some reason it's impossible to use binding:"required" for query params

type LimitOffset struct {
	Offset int `form:"offset" binding:"required"`
	Limit  int `form:"limit" binding:"required"`
}

func CategoryBooks(conn *mgo.Collection, c *gin.Context) {
	var query_params LimitOffset
	if err := c.BindQuery(&query_params); err != nil {
		badRequestResponse(c, err)
		return
	}
        ...
}

response:
{"description":"Key: 'LimitOffset.Offset' Error:Field validation for 'Offset' failed on the 'required' tag","status":"error"}

url with query params:

http://localhost:8000/categories/Python?offset=0&limit=2

@mdnight Can you provide mini codes to help reproduce this issue？

@mdnight I use the follow code it's ok.

package main

import (
	"fmt"

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

type LimitOffset struct {
	Offset int `form:"offset" binding:"required"`
	Limit int `form:"limit" binding:"required"`
}

func main() {
	r := gin.Default()
	r.GET("/t", func(c *gin.Context) {
		var query_params LimitOffset
		if err := c.BindQuery(&query_params); err != nil {
			fmt.Println(err)
			return
		}
		fmt.Println("ok")
	})
	r.Run()
}
