gin golang Invalid validation tag on field ‘AId‘

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"
  
}
