Web 应用程序的 Firebase 多因素身份验证返回“auth/code-expired”错误

Question

我正在尝试对使用 Angular 构建的 Web 应用程序实施多因素身份验证，这会引发以下错误："auth/code-expired", "SMS 代码已过期。请重新发送验证码再试一次。”即使我在一分钟内输入代码。

我已经手动将我的电话号码（iPhone）注册到 ID 平台，并且能够接收到我的手机的验证码。 另外，如果我将手机号和验证码输入ID平台进行开发，我可以毫无问题地登录。

我已阅读此问题，但似乎不适用于我的情况，因为当我收到验证码时身份验证状态不会改变。 The sms code has expired. Please re-send the verification code to try again

谁能告诉我怎么了？下面是我的代码。

    <section>
      <h4>Sign in with MFA</h4>
      <div class="flex">
        <input placeholder="Email" [(ngModel)]="email">
        <input placeholder="Password" [(ngModel)]="pass">
        <button (click)="onAuth()">Submit</button>
      </div>
    </section>

          } else {

            console.log('Unsupported second factor.');

          }
        } else {
          alert('Sign in Failed');
        }
      });

  }

}

提前谢谢你。

我已经解决了这个问题，但会留下记录。 以下代码不正确：

// Incorrect

          if (this.resolver.hints[selectedIndex].factorId === firebase.default.auth.PhoneMultiFactorGenerator.FACTOR_ID) {
            const phoneNumber = prompt('Enter your phone number with a country code (e.g. +18881231234).');
            const phoneInfoOptions = {
              multiFactorHint: this.resolver.hints[selectedIndex],
              session: this.resolver.session,
              phoneNumber
            };
            const phoneAuthProvider = new firebase.default.auth.PhoneAuthProvider();
            // Send SMS verification code
   
            return phoneAuthProvider.verifyPhoneNumber(phoneInfoOptions.phoneNumber, this.windowRef.recaptchaVerifier)
              .then((verificationId) => {...

一旦我从 phoneInfoOptions 中取出 phoneNumber 并提供 phoneInfoOptions 来验证PhoneNumber()，MFA 就会成功通过。

// Correct

          if (this.resolver.hints[selectedIndex].factorId === firebase.default.auth.PhoneMultiFactorGenerator.FACTOR_ID) {
            prompt('Enter your phone number with a country code (e.g. +18881231234).');
            const phoneInfoOptions = {
              multiFactorHint: this.resolver.hints[selectedIndex],
              session: this.resolver.session,
            };
            const phoneAuthProvider = new firebase.default.auth.PhoneAuthProvider();
            // Send SMS verification code
   
            return phoneAuthProvider.verifyPhoneNumber(phoneInfoOptions, this.windowRef.recaptchaVerifier)
              .then((verificationId) => {...
