使用验证V2 Golang软件包的正则表达式电话号码不起作用

I am having some trouble when using github.com/go-validator/validator to validate regex some phone numbers with this prefix +62, 62, 0, for instance number e.g. +628112blabla, 0822blablabla, 628796blablabla.

I have try my regex on online regex tester and no issue with the regex on that. Here the regex is :

(0|\+62|062|62)[0-9]+$

But when I try with my go implement with it, the regex not working. This is my code for implement the purpose :

type ParamRequest struct {
    PhoneNumber string `validate:"nonzero,regexp=(0|\+62|062|62)[0-9]+$"`
    ItemCode    string `validate:"nonzero"`
    CallbackUrl string `validate:"nonzero"`
}

func (c *TopupAlloperatorApiController) Post() {
    var v models.TopupAlloperatorApi

    interf := make(map[string]interface{})

    json.Unmarshal(c.Ctx.Input.RequestBody, &interf)

    logs.Debug(" Json Input Request ", interf)
    var phone, item, callback string

    if _, a := interf["PhoneNumber"].(string); a {
        phone = interf["PhoneNumber"].(string)
    }
    if _, b := interf["ItemCode"].(string); b {
        item = interf["ItemCode"].(string)
    }

    if _, c := interf["CallbackUrl"].(string); c {
        callback = interf["CallbackUrl"].(string)
    }

    ve := ParamRequest{
        PhoneNumber: phone,
        ItemCode:    item,
        CallbackUrl: callback,
    }

    logs.Debug(" Param Request ", ve)



    err := validator.Validate(ve)
    if err == nil {
       //success
    }else{
      // not success
    }

Many thanks for anything help. Thank you.

    Because you are using regexp to check PhoneNumber that won't be matching if the value is empty it is better to remove nonzero from the validation.
    I have checked out documentation and haven't found examples where you can use both: nonzero and regexp.
    Also you need to make your regex symbol-escaped, otherwise it won't be detected by reflection. It means you should use (0|\\+62|062|62)[0-9]+$ in your code. Here is example where problem is: symbol escaping in struct tags
    And also, please try to use this regexp: ^\\+{0,1}0{0,1}62[0-9]+$
