Firebase 身份驗證 UI 的電子郵件驗證

Question

我在一個 android 應用程序中使用firebase auth UI ( FirebaseUI-Android )，用戶可以在其中注冊個人email 、 Facebook 、 number和Gmail帳戶。 我的問題是當用戶使用他的個人電子郵件 ID 注冊時，我需要進行電子郵件驗證。

    List<AuthUI.IdpConfig> providers = Arrays.asList(
        new AuthUI.IdpConfig.Builder(AuthUI.EMAIL_PROVIDER).build(),
        new AuthUI.IdpConfig.Builder(AuthUI.PHONE_VERIFICATION_PROVIDER).build(),
        new AuthUI.IdpConfig.Builder(AuthUI.FACEBOOK_PROVIDER).build(),
        new AuthUI.IdpConfig.Builder(AuthUI.GOOGLE_PROVIDER).build());

    startActivityForResult(
        AuthUI.getInstance()
                .createSignInIntentBuilder()
                .setIsSmartLockEnabled(true)
                .setTheme(R.style.GreenTheme)
                .setTosUrl("https://termsfeed.com/blog/terms-conditions-mobile-apps/")
                .setPrivacyPolicyUrl("https://superapp.example.com/privacy-policy.html")
                .setAvailableProviders(providers)
                .build(),
        RC_SIGN_IN);
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    // RC_SIGN_IN is the request code you passed into startActivityForResult(...) when starting the sign in flow.
    if (requestCode == RC_SIGN_IN) {
        IdpResponse response = IdpResponse.fromResultIntent(data);
        // Successfully signed in
        if (resultCode == RESULT_OK) {
            startActivity(new Intent(Login.this,MainActivity.class));
            finish();
            return;
        } else {
            // Sign in failed
            if (response == null) {
                Toasty.error(getApplicationContext(),"Sign in cancelled",Toast.LENGTH_SHORT, true).show();
                return;
            }

            if (response.getErrorCode() == ErrorCodes.NO_NETWORK) {
                Toasty.error(getApplicationContext(),"No internet connection",Toast.LENGTH_SHORT, true).show();
                return;
            }

            if (response.getErrorCode() == ErrorCodes.UNKNOWN_ERROR) {
                Toasty.error(getApplicationContext(),"Unkown Error",Toast.LENGTH_SHORT, true).show();
                return;
            }
        }
        Toasty.error(getApplicationContext(),"Unknown sign in response",Toast.LENGTH_SHORT, true).show();
    }
}  

這是我對注冊選項的意圖。

Answer 1

你可以簡單地做如下，

1. 獲取當前 Firebase 用戶實例，

    final FirebaseUser currentUser = mAuth.getCurrentUser();

2. 檢查提供者是否是password表明使用的登錄方法是Email Auth ，

    if(null != currentUser) { if("password".equals(currentUser.getProviderData().get(0).getProviderId())) { /* Handle Verification */ } }

   參考鏈接： https : //firebase.google.com/docs/reference/android/com/google/firebase/auth/EmailAuthProvider#PROVIDER_ID

3. 檢查用戶是否已通過驗證，

    currentUser.isEmailVerified();

4. 如果用戶未通過驗證，則可以使用以下代碼發送驗證電子郵件，

    if (!currentUser.isEmailVerified()) { /* Do Something */ } /* Send Verification Email */ currentUser.sendEmailVerification() .addOnCompleteListener(this, new OnCompleteListener() { @Override public void onComplete(@NonNull Task task) { /* Check Success */ if (task.isSuccessful()) { Toast.makeText(getApplicationContext(), "Verification Email Sent To: " + currentUser.getEmail(), Toast.LENGTH_SHORT).show(); } else { Log.e(TAG, "sendEmailVerification", task.getException()); Toast.makeText(getApplicationContext(), "Failed To Send Verification Email!", Toast.LENGTH_SHORT).show(); } } });

完成所有部分后，最終的代碼片段應如下所示：

最終代碼片段：

if (requestCode == RC_SIGN_IN) {
    IdpResponse response = IdpResponse.fromResultIntent(data);

    /* Success */
    if (resultCode == RESULT_OK) {
        final FirebaseUser currentUser = mAuth.getCurrentUser();

        if(null != currentUser) {
            if("password".equals(currentUser.getProviderData().get(0).getProviderId())) {
                if(!currentUser.isEmailVerified()) {
                    /* Send Verification Email */
                    currentUser.sendEmailVerification()
                        .addOnCompleteListener(this, new OnCompleteListener() {
                            @Override
                            public void onComplete(@NonNull Task task) {
                                /* Check Success */
                                if (task.isSuccessful()) {
                                    Toast.makeText(getApplicationContext(),
                                            "Verification Email Sent To: " + currentUser.getEmail(),
                                            Toast.LENGTH_SHORT).show();
                                } else {
                                    Log.e(TAG, "sendEmailVerification", task.getException());
                                    Toast.makeText(getApplicationContext(),
                                            "Failed To Send Verification Email!",
                                            Toast.LENGTH_SHORT).show();
                                }
                            }
                        });

                    /* Handle Case When Email Not Verified */
                }
            }

            /* Login Success */
            startActivity(new Intent(Login.this, MainActivity.class));
            finish();
            return;
        }
    } else {
        /* Handle Failure */
    }
}

Answer 2

@user2004685 上面的回答給出了很好的提示。 但它至少對最新的 firebase-ui 不起作用，因為currentUser.getProviderData().get(0).getProviderId()返回“ currentUser.getProviderData().get(0).getProviderId() ”。

所以更新的解決方案是

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

  if (requestCode == RC_SIGN_IN) {
    IdpResponse response = IdpResponse.fromResultIntent(data);

    /* Success */
    if (resultCode == RESULT_OK) {
        final FirebaseUser currentUser = mAuth.getCurrentUser();

        if(null != currentUser) {
            if(currentUser.getEmail()!=null) {
                if(!currentUser.isEmailVerified()) {
                    /* Send Verification Email */
                    currentUser.sendEmailVerification()
                        .addOnCompleteListener(this, new OnCompleteListener() {
                            @Override
                            public void onComplete(@NonNull Task task) {
                                /* Check Success */
                                if (task.isSuccessful()) {
                                    Toast.makeText(getApplicationContext(),
                                            "Verification Email Sent To: " + currentUser.getEmail(),
                                            Toast.LENGTH_SHORT).show();
                                } else {
                                    Log.e(TAG, "sendEmailVerification", task.getException());
                                    Toast.makeText(getApplicationContext(),
                                            "Failed To Send Verification Email!",
                                            Toast.LENGTH_SHORT).show();
                                }
                            }
                        });

                    /* Handle Case When Email Not Verified */
                }
            }

            /* Login Success */
            startActivity(new Intent(Login.this, MainActivity.class));
            finish();
            return;
        }
    } else {
        /* Handle Failure */
    }
  }
}

只需將if("password".equals(currentUser.getProviderData().get(0).getProviderId()))替換為if(currentUser.getEmail()!=null)
