validate

regular

type UserBasic struct {
	Phone         string `json:"phone" form:"phone" valid:"matches(^1[3-9]{1}\\d{9}$)"` // 正則
}

example

    "github.com/smokezl/govalidators"
)
type Class struct {
    Cid       int64  `validate:"required||integer=10000,_"`

}

• required 判斷欄位對應的值是否是對應型別的零值
• integer、array、string 表示欄位型別是否是整數型別，如果integer後邊不接=?,?，那麼表示只判斷是否是整數型別，如果後邊接=?,?，那麼有四種寫法
  • (1). integer=10 表示欄位值 = 10
  • (2). integer=_ ,10 表示欄位值 <= 10，欄位值最小值為欄位對應型別的最小值(比如欄位對應型別為int8，那麼最小為−128)，最大值為10
  • (3). integer=10, _ 表示欄位值 >= 10，欄位值最小值為10，最大值為欄位對應型別的最大值(比如欄位對應型別為int8，那麼最大為127)
  • (4). integer=1,20 表示欄位值 >=1 並且 <= 20
• mail 表示欄位值是否是合法的email地址
• url 表示欄位值是否是合法的url地址
• in 表示欄位值在in指定的值中，比如 Hobby 欄位中,in=swimming,running,drawing，表示 Hobby 欄位的值，只能swimming,running,drawing中的一個或多個
• datetime 表示欄位值符合日期型別，如果datetime後邊不接=?，那麼預設為Y-m-d H:i:s，否則驗證器會按照指定格式判斷，比如 datetime=Y-m、datetime=Y/m/d H:i:s等，可以是Y m d H i s 的隨意拼接
• unique 表示欄位值唯一，比如 Hobby 欄位的 unique，表示 Hobby 欄位值唯一，Class 中，Cname 欄位的 unique，表示 Cname 欄位值唯一
• valid:"matches(^1[3-9]{1}\\d{9}$)" 正則匹配
