使用错误的验证码进行身份验证时出现异常 [英] Exception when authenticating with wrong verification code

问题描述

我正在使用 Firebase 电话身份验证来验证用户帐户.当我尝试使用错误的验证码进行身份验证时，我收到 IllegalArgumentException.有没有办法在不使用 try catch 块的情况下解决这个问题?

I'm using Firebase Phone Authentification to verify users accounts. When I try to authenticate with a wrong verification code, I get an IllegalArgumentException. Is there any way to fix that without using try catch blocks?

这是异常消息:

java.lang.IllegalArgumentException: Cannot create PhoneAuthCredential without either verificationProof, sessionInfo, or temporaryProof.
                                                                 at com.google.android.gms.common.internal.zzbq.checkArgument(Unknown Source)

                                                                 at android.app.ActivityThread.main(ActivityThread.java:5951)
                                                                 at java.lang.reflect.Method.invoke(Native Method)
                                                                 at java.lang.reflect.Method.invoke(Method.java:372)
                                                                 at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1400)
                                                                 at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1195)

这是我得到错误的那一行:

And here is the line where I get the error :

PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationCode, inputCode);

我故意在 inputCode 中使用了错误的验证码，并希望得到错误消息而不是异常.

I'm intentionally using wrong verification code in inputCode and hoping to get an error message instead of the exception.

推荐答案

调用 PhoneAuthProvider.getCredential(...) 返回一个 PhoneAuthCredential 对象，定义为:

包装电话号码和验证信息以进行身份​​验证.

Wraps phone number and verification information for authentication purposes.

所以 getCredential() 不能返回错误信息.相反，如果您提供的验证/凭据信息有问题，它会引发异常.

So getCredential() cannot return an error message. Instead it throws an exception if there is a problem with the verification/credential information you provided.
