结构体如下
type CreateParams struct {AId uint `json:"a_id" binding:"required,"BId uint `json:"b_id" binding:"required,"}
运行时报错:Invalid validation tag on field 'AId'
原因:在binding中,如果只有一个要求,不要加逗号,否则会逗号被当作一个词验证
修改:
type CreateParams struct {AId uint `json:"a_id" binding:"required"BId uint `json:"b_id" binding:"required"}
