Firebase 短信验证/身份验证

Question

对于一个客户项目，我正在创建一个简单的混合应用程序，它提供的功能非常简单，但流量很高。该应用程序通常不需要后端，因为它非常非常简单，而且 firebase 似乎是该项目的完美解决方案。

唯一让我卡住的部分是使用 Firebase 进行短信验证/身份验证。然而，经过一些密集的谷歌搜索和文档阅读，我开始意识到没有简单的方法可以做到这一点。到目前为止，这是我调查过的内容：

Fabric.io Digits has a great JS API, however for some reason firebase and digits won't play nicely together : https://groups.google.com/forum/#!topic/firebase-talk/sB7lPuyCVBQ
Facebook Account Kit - 就在一周前，Facebook 发布了一个新的短信验证和身份验证工具包，尽管它仍然感觉它与 fabric.io 数字有同样的问题，至少在证明不是这样之前.
通过 NodeJS 的 Twilio / Nexmo - 这些都是具有出色 JS API 的史诗服务，但据我所知，这将需要一个单独的后端服务器来处理 JWT 令牌交换。而且它本身是另一台服务器，在高流量期间会成为瓶颈，并且是另一个安全漏洞点，客户端团队必须单独管理。不是最愉快的。
Twilio / Nexmo 和 Auth0 - 到目前为止，这似乎是最好的选择，其中身份验证和用户管理由 Auth0 处理，但是考虑到 twilio 或 nexmo 和 auth0 都是付费解决方案，此解决方案很快就会变得昂贵。并不是说我是个吝啬鬼，希望事情能免费运行——但感觉这是一个非常昂贵的额外步骤，因为它只是转发令牌。 [参见：clients-from-hell]
我记得在某处读过，建议使用 phone 数字作为 firebase 上的电子邮件，例如：123-456-7890@example.com 并使用通过短信发送的安全代码作为密码，这听起来由于许多不同的原因，非常粗略。

通常对于混合移动应用程序，non-native 它们或 JS API 的性质是罪魁祸首，但第一次（至少对我而言）感觉并非如此。我认为此时 Firebase 不是一个有效的选择，但想在开始研究 AWS 并为客户设置整个后端之前最后一次询问社区中充满爱心和关怀的成员。

除了 middle-service / 没有后端服务器，还有其他方法可以处理这种类型的身份验证吗？任何人都有使用这些解决方案的经验吗？

Phone Verification & Authentication is now natively available in Firebase. 请参阅下面我的 self-posted 回答。

更新：2017 年 4 月

Firebase 现在原生支持 Cloud Functions。您现在可以使用 Cloud Functions 完成此操作以及更多操作，而无需设置任何服务器。

更新：2017 年 10 月

Fabric.io 和 Firebase 合作并集成了 Digits in Firebase phone authentication 并为 Fabric 推出了更多功能。

我无法对你提到的每一个集成进行说明，但你可能想尝试另一个 Twilio 的服务，Authy。

我们最近通过教程发布了生产就绪代码示例，以帮助人们解决此类问题。

一个这样的例子将引导您完成：

向移动 Authy 应用程序发送 OneTouch 推送通知或
通过移动 Authy 应用发送令牌或
在通过 Authy 发送的短信中发送一次性令牌 Twilio.

就是2FA with Authy tutorial。以下 Node.js 片段显示端点等待用户状态被批准或拒绝。如果用户批准了 OneTouch 请求，我们会将他们的会话保存为 confirmed，这将让他们正式登录。

如果请求被拒绝，我们将呈现 /verify 页面并要求用户使用令牌登录。

// Internal endpoint for checking the status of OneTouch
exports.authyStatus = function(request, response) {
    var status = (request.user) ? request.user.authyStatus : 'unverified';
    if (status == 'approved') {
        request.session.confirmed = true;
        request.session.save(function(err) {
            if (err) return error(response, 500, 
                'There was an error validating your session.');
        });
    }
    if (!request.session) {
        return error(response, 404, 'No valid session found for this user.');
    } else {
        response.send({ status: status });
    }   
};

所以，这确实需要你有一个服务器。但是如果试一试示例，这应该可以帮助您确定最适合您的应用程序的内容。

截至 2017 年 5 月 17 日，Firebase 的优秀人员已将 Digits 的 phone 身份验证融入 Firebase。 This is now incredibly easy to achieve natively within Firebase, more or less with the flip of a switch and without the need of an external service or anything alike. You can read more about it in the docs:)

现在 phone 身份验证可用 firebase.Here 是 Phone 使用 Firebase 进行身份验证的代码：

EditText phoneNum,Code;// two edit text one for enter phone number other for enter OTP code
Button sent_,Verify;// sent button to request for verification and verify is for to verify code
private PhoneAuthProvider.ForceResendingToken mResendToken;

            FirebaseUser user = firebaseAuth.getCurrentUser();
            if (user != null) {
                Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
            } else {
                Log.d(TAG, "onAuthStateChanged:signed_out");
            }
            // ...
        }
    };


    //init all auth process
    phoneAutenticationService = new PhoneAutenticationService(this,mAuth);

 @Override
public void onStart() {
    super.onStart();
    mAuth.addAuthStateListener(mAuthListener);
    getActivity().registerReceiver(smsBroadcastReceiver, filter);// define e broadcast receiver to intercept a sms verification code
}

@Override
public void onStop() {
    super.onStop();
    if (mAuthListener != null) {
        mAuth.removeAuthStateListener(mAuthListener);sms code
    }
    getActivity().unregisterReceiver(smsBroadcastReceiver);

}

最后调用firebase方法进行认证

public void startAuthenticationByPhone(){
    if (!validatePhoneNumber(phoneInput)) {
        return;
    }
    startPhoneNumberVerification(phoneInput.getText().toString());

}......
