File Binding Not Working!

[bnuby]

type UpdateUserOperatorReq struct {
	File     *multipart.FileHeader `form:"file"`
	UID      *string                        `form:"uid" json:"uid"`
}

...

req := &UpdateUserOperatorReq{}
if err := c.ShouldBind(req); err != nil {
	c.JSON(status, "")
	return
}
logger(req.File)
// <nil>

I follow the example, but still getting nil. Please help fix this bug
