使用验证V2 Golang软件包的正则表达式电话号码不起作用

Question

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.
