ERROR TypeError: a.getCountryCodeOrDefault is not a function

Question

我正在尝试在 Angular 项目中使用 google-libphonenumber 包来验证 phone 数字

import { PhoneNumberUtil } from 'google-libphonenumber';

  public phoneUtil = PhoneNumberUtil.getInstance();

  phoneUtil.isValidNumber('+919421013328');

但它给了我

TypeError: a.getCountryCodeOrDefault is not a function.

有人可以帮我解决这个问题吗？

Answer 1

来自the google-libphonenumber package readme：

Most libphonenumber functions expect to receive an instance of libphonenumber.PhoneNumber which can be obtained by calling phoneUtil.parse or phoneUtil.parseAndKeepRawInput on a raw (string) number, otherwise it will throw errors like TypeError: a.getCountryCodeOrDefault is not a function.

phoneUtil.isValidNumberForRegion(phoneUtil.parse('202-456-1414', 'US'), 'US');

或者如果您有多个国家代码：

phoneUtil.parseAndKeepRawInput('+919421013329');
