用于验证字符串、数组、切片、结构体的包；Package for verifying strings, arrays, slices, structures
安装前请确认你的电脑上go环境已安装好，可以使用以下命令
go get -u github.com/vcqr/validator引用包到你的项目中
import "github.com/vcqr/validator"struct验证使用的是struct tag，则必须以“validate”关键字开头，验证使用的方法区分大小写
// 定义struct
type User struct {
Id int `valid:"required|min:0"`
Name string `valid:"required|range:6,20"`
Age int `valid:"required|range:1,120"`
Sex int `valid:"required|in:0,1"`
IpAddr string `valid:"isIP"`
BlogUrl string `valid:"isURL"`
IdCard string `valid:"cn_IdCard"`
Mobile string `valid:"cn_Mobile"`
Tel string `valid:"cn_Tel"`
}验证struct
u := User{1, "dzhang", 26, 1, "127.0.0.1", "https://a.com", "32112319000101100x", "19956785678", "021-60123456"}
// 初始化验证器
validator := validator.New()
// 开始验证
validator.Struct(u).Validate()validator := validator.New()
// 自定义验证器
// arg参数如下说明：
// 假设验证规则为exp:xxx,xxx
// args[0] 验证规则具体内容 xxx,xxx
// args[1] 验证数据类型 string, int, []string, [1]int, map[string]interface{}等
// args[2] 待验证数据
validator.TagMap["exp"] = func(args ...reflect.Value) bool {
//TODO 你的处理逻辑
return false
}
// 你可以这样使用
validator.AddRule("demo", "int", "sometimes|exp:xx,xxx", target).Validate()// 使用map规则，非struct定义方式
// 字段格式为：[]string{"数据类型", "验证规则"}
ruleMap := map[string][]string{
"Id": []string{"int", "required|min:100"},
"Name": []string{"string", "required|min:10"},
"Email": []string{"string", "required|Email"},
"From": []string{"string", "sometimes|in:cn,us,uk,tk,tw"},
"Age": []string{"int", "range:1,150"},
}
dataMap := map[string]interface{}{
"Id": 1,
"Name": "zhangsan-123",
"Email": "www@www.com",
"Age": 100,
}
// 执行验证
validator.AddMapRule(ruleMap, dataMap).Validate()package main
