golang初学者，在项目开发过程中造了一个简单的验证器轮子，欢迎大大们提宝贵建议和指导
go get github.com/smokezl/govalidators
import "github.com/smokezl/govalidators"为 struct 指定验证器
package main
import "github.com/smokezl/govalidators"
type Class struct {
Cid int64 `validate:"required||integer=1,1000000"`
Cname string `validate:"required||string=1,5||unique"`
BeginTime string `validate:"required||datetime=H:i"`
}
type Student struct {
Uid int64 `validate:"required||integer=1,1000000"`
Name string `validate:"required||string=1,5"`
Age int64 `validate:"required||integer=10,30"`
Sex string `validate:"required||in=male,female"`
Email string `validate:"email"`
PersonalPage string `validate:"url"`
Hobby []string `validate:"array=_,2||unique||in=swimming,running,drawing"`
CreateTime string `validate:"datetime"`
Class []Class `validate:"array=1,3"`
}验证
validator := govalidators.New()
if err := validator.Validate(student); err != nil {
fmt.Println(err)
}type ValidatorF func(params map[string]interface{}, val reflect.Value, args ...string) (bool, error)自定义函数

fmt.Println("validationMethod")
...
return true, nil
}type Validator interface {
Validate(params map[string]interface{}, val reflect.Value, args ...string) (bool, error)
}自定义struct
type UserValidator struct {

/**
