英文:
Go doesn't recognize regexp
问题
我需要将特殊字符（@＃$％^＆amp; .？）添加到oneof或使用regexp，但是regexp在执行时出现错误是未定义的。我目前正在使用oneof=大写&小写&数字。此验证器将检查密码是否至少包含1个大写字母、1个小写字母、1个数字和1个特殊字符。
示例代码：
package main
import (
"fmt"
"github.com/go-playground/validator/v10"
)
type UserReg struct {
Username string `validate:"required,min=4,max=15"`
Email string `validate:"required,email"`
Password string `validate:"required,min=8,max=20,eqfield=ConfirmPassword,oneof=uppercase&lowercase&numeric"`
ConfirmPassword string `validate:"required,min=8,max=20,oneof=uppercase&lowercase&numeric"`
}
type UserReg2 struct {
Username string `validate:"required,min=4,max=15"`
Email string `validate:"required,email"`
Password string `validate:"required,min=8,max=20,eqfield=ConfirmPassword,regexp=^(?=.*[a-zA-Z0-9!@#$%^&.?/]).$"`
ConfirmPassword string `validate:"required,min=8,max=20,regexp=^(?=.*[a-zA-Z0-9!@#$%^&.?/]).$"`
}
func main() {
fmt.Println("开始工作测试，不检查特殊字符")
ut := UserReg{
Username: "Joe23",
Email: "Joe@joe.com",
Password: "Pa55w0rd",
ConfirmPassword: "Pa55w0rd",
}
validate := validator.New()
err := validate.Struct(ut)
fmt.Println(err)
fmt.Println("结束工作测试，不检查特殊字符")
fmt.Println("开始失败测试，检查特殊字符")
ut2 := UserReg2{
Username: "Joe23",
Email: "Joe@joe.com",
Password: "Pa$$w0rd",
ConfirmPassword: "Pa$$w0rd",
}
err2 := validate.Struct(ut2)
fmt.Println(err2)
fmt.Println("结束失败测试，检查特殊字符")
}
英文:
I need to add special characters (@#$%^&.?) to the oneof or use regexp, but regexp errors on execution is undefined. I am currently using, oneof=uppercase&lowercase&numeric. this validator would be checking if the passwords contain at least 1 uppercase letter, 1 lowercase letter, 1 number and 1 special character.
Sample Code ==>
package main
import (
"fmt"
"github.com/go-playground/validator/v10"
)
type UserReg struct {
Username string `validate:"required,min=4,max=15"`
Email string `validate:"required,email"`
Password string `validate:"required,min=8,max=20,eqfield=ConfirmPassword,oneof=uppercase&lowercase&numeric"`
ConfirmPassword string `validate:"required,min=8,max=20,oneof=uppercase&lowercase&numeric"`
}
type UserReg2 struct {
Username string `validate:"required,min=4,max=15"`
Email string `validate:"required,email"`
Password string `validate:"required,min=8,max=20,eqfield=ConfirmPassword,regexp=^(?=.*[a-zA-Z0-9!@#$%^&.?/]).$"`
ConfirmPassword string `validate:"required,min=8,max=20,regexp=^(?=.*[a-zA-Z0-9!@#$%^&.?/]).$"`
}
func main() {
fmt.Println("Start of working test w/o check for special characters")
ut := UserReg{
Username: "Joe23",
Email: "Joe@joe.com",
Password: "Pa55w0rd",
ConfirmPassword: "Pa55w0rd",
}
validate := validator.New()
err := validate.Struct(ut)
fmt.Println(err)
fmt.Println("End of working test w/o check for special characters")
fmt.Println("Start of failing test w/ check for special characters")
ut2 := UserReg2{
Username: "Joe23",
Email: "Joe@joe.com",
Password: "Pa$$w0rd",
ConfirmPassword: "Pa$$w0rd",
}
err2 := validate.Struct(ut2)
fmt.Println(err2)
fmt.Println("End of failing test w/ check for special characters")
}

在玩弄了一番之后，我通过更改UserReg中的代码行得出了以下结果：
Password string `validate:"required,min=8,max=20,eqfield=ConfirmPassword,oneof=uppercase&lowercase&numeric&@ # $ % ^ & . ? /"`
ConfirmPassword string `validate:"required,min=8,max=20,oneof=uppercase&lowercase&numeric&@ # $ % ^ & . ? /"`
英文:
After playing around I came up with by changing the line in UserReg to:
Password string `validate:"required,min=8,max=20,eqfield=ConfirmPassword,oneof=uppercase&lowercase&numeric&@ # $ % ^ \& . ? \/"`
ConfirmPassword string `validate:"required,min=8,max=20,oneof=uppercase&lowercase&numeric&@ # $ % ^ \& . ? \/"`
