وإجراء المصادقة مع Firebase باستخدام بيانات اعتماد Firebase:
إذا كان برنامجك يحتوي على حلقة تحديث تعمل بانتظام (مثلاً عند معدل 30 أو 60 ثانية)
مرة في الثانية)، يمكنك الاطلاع على النتائج مرة واحدة لكل تحديث باستخدام
Auth::SignInAndRetrieveDataWithCredentialLastResult:
firebase::Future<firebase::auth::AuthResult>result=auth->SignInAndRetrieveDataWithCredentialLastResult();if(result.status()==firebase::kFutureStatusComplete){if(result.error()==firebase::auth::kAuthErrorNone){firebase::auth::AuthResultauth_result=*result.result();printf("Sign in succeeded for `%s`\n",auth_result.user.display_name().c_str());}else{printf("Sign in failed with error '%s'\n",result.error_message());}}
تحتوي بعض البرامج على دوال Update اسمها 30 أو 60 مرة في الثانية الواحدة.
على سبيل المثال، تتبع العديد من الألعاب هذا النموذج. بإمكان هذه البرامج استدعاء LastResult
لاستطلاع المكالمات غير المتزامنة.
ومع ذلك، إذا كان برنامجك يستند إلى الأحداث، قد تفضِّل تسجيل دوال معاودة الاتصال.
يتم استدعاء دالة الاستدعاء عند اكتمال المستقبل.

الخطوات التالية
بعد تسجيل المستخدم الدخول لأول مرة، يتم إنشاء حساب مستخدم جديد
المرتبطة ببيانات الاعتماد - أي اسم المستخدم وكلمة المرور،
أو الرقم أو معلومات مقدم المصادقة - المستخدم الذي سجّل الدخول باستخدامه. هذا الجديد
كجزء من مشروع Firebase، ويمكن استخدامه لتحديد
مستخدم في كل تطبيق في مشروعك، بغض النظر عن كيفية تسجيل دخوله.
firebase::auth::Useruser=auth->current_user();if(user.is_valid()){std::stringname=user.display_name();std::stringemail=user.email();std::stringphoto_url=user.photo_url();// The user's ID, unique to the Firebase project.// Do NOT use this value to authenticate with your backend server,// if you have one. Use firebase::auth::User::Token() instead.std::stringuid=user.uid();}
في Firebase Realtime Database وCloud Storageقواعد الأمان، تتيح لك
الحصول على معرّف المستخدم الفريد للمستخدم الذي سجّل الدخول من المتغير auth،
واستخدامها للتحكم في البيانات التي يمكن للمستخدم الوصول إليها

[Add Firebase to your C++ project](/docs/cpp/setup#note_select_platform).\n2. Enable Google as a sign-in method in the Firebase console:\n 1. In the [Firebase console](//console.firebase.google.com/), open the **Auth** section.\n 2. On the **Sign in method** tab, enable the **Google** sign-in method and click **Save**.\n3. When prompted in the console, download the updated Firebase config file (`google-services.json`), which now contains the OAuth client information required for Google sign-in.\n4. Move this updated config file into your Android Studio project, *replacing* the now-outdated corresponding config file. (See [Add Firebase to your Android project](/docs/android/setup#add-config-file).)\n\nAccess the `firebase::auth::Auth` class The `Auth` class is the gateway for all API calls.\n\n1. Add the Auth and App header files: \n\n ```c++\n #include \"firebase/app.h\"\n #include \"firebase/auth.h\"\n ```\n2. In your initialization code, create a [`firebase::App`](/docs/reference/cpp/class/firebase/app) class. \n\n ```c++\n #if defined(__ANDROID__)\n firebase::App* app =\n firebase::App::Create(firebase::AppOptions(), my_jni_env, my_activity);\n #else\n firebase::App* app = firebase::App::Create(firebase::AppOptions());\n #endif // defined(__ANDROID__)\n ```\n3. Acquire the `firebase::auth::Auth` class for your `firebase::App`. There is a one-to-one mapping between `App` and `Auth`. \n\n ```c++\n firebase::auth::Auth* auth = firebase::auth::Auth::GetAuth(app);\n ```\n\nAuthenticate with Firebase\n\n1. Follow instructions for [Android](/docs/auth/android/google-signin#authenticate_with_firebase) and [iOS+](/docs/auth/ios/google-signin#2_implement_google_sign-in) to get an ID token for the Google sign in.\n2. After a user successfully signs in, exchange the ID token for a Firebase credential, and authenticate with Firebase using the Firebase credential: \n\n ```c++\n firebase::auth::Credential credential =\n firebase::auth::GoogleAuthProvider::GetCredential(google_id_token,\n nullptr);\n firebase::Future\u003cfirebase::auth::AuthResult\u003e result =\n auth-\u003eSignInAndRetrieveDataWithCredential(credential);\n ```\n3. If your program has an update loop that runs regularly (say at 30 or 60 times per second), you can check the results once per update with `Auth::SignInAndRetrieveDataWithCredentialLastResult`: \n\n ```c++\n firebase::Future\u003cfirebase::auth::AuthResult\u003e result =\n auth-\u003eSignInAndRetrieveDataWithCredentialLastResult();\n if (result.status() == firebase::kFutureStatusComplete) {\n if (result.error() == firebase::auth::kAuthErrorNone) {\n firebase::auth::AuthResult auth_result = *result.result();\n printf(\"Sign in succeeded for `%s`\\n\",\n auth_result.user.display_name().c_str());\n } else {\n printf(\"Sign in failed with error '%s'\\n\", result.error_message());\n }\n }\n ```\n Or, if your program is event driven, you may prefer to [register a callback on the\n Future](#register_callback_on_future).\n\nRegister a callback on a Future Some programs have `Update` functions that are called 30 or 60 times per second. For example, many games follow this model. These programs can call the `LastResult` functions to poll asynchronous calls. However, if your program is event driven, you may prefer to register callback functions. A callback function is called upon completion of the Future. \n\n```c++\nvoid OnCreateCallback(const firebase::Future\u003cfirebase::auth::User*\u003e& result,\n void* user_data) {\n // The callback is called when the Future enters the `complete` state.\n assert(result.status() == firebase::kFutureStatusComplete);\n\n // Use `user_data` to pass-in program context, if you like.\n MyProgramContext* program_context = static_cast\u003cMyProgramContext*\u003e(user_data);\n\n // Important to handle both success and failure situations.\n if (result.error() == firebase::auth::kAuthErrorNone) {\n firebase::auth::User* user = *result.result();\n printf(\"Create user succeeded for email %s\\n\", user-\u003eemail().c_str());\n\n // Perform other actions on User, if you like.\n firebase::auth::User::UserProfile profile;\n profile.display_name = program_context-\u003edisplay_name;\n user-\u003eUpdateUserProfile(profile);\n\n } else {\n printf(\"Created user failed with error '%s'\\n\", result.error_message());\n }\n}\n\nvoid CreateUser(firebase::auth::Auth* auth) {\n // Callbacks work the same for any firebase::Future.\n firebase::Future\u003cfirebase::auth::AuthResult\u003e result =\n auth-\u003eCreateUserWithEmailAndPasswordLastResult();\n\n // `&my_program_context` is passed verbatim to OnCreateCallback().\n result.OnCompletion(OnCreateCallback, &my_program_context);\n}\n```\nThe callback function can also be a lambda, if you prefer. \n\n```c++\nvoid CreateUserUsingLambda(firebase::auth::Auth* auth) {\n // Callbacks work the same for any firebase::Future.\n firebase::Future\u003cfirebase::auth::AuthResult\u003e result =\n auth-\u003eCreateUserWithEmailAndPasswordLastResult();\n\n // The lambda has the same signature as the callback function.\n result.OnCompletion(\n [](const firebase::Future\u003cfirebase::auth::User*\u003e& result,\n void* user_data) {\n // `user_data` is the same as &my_program_context, below.\n // Note that we can't capture this value in the [] because std::function\n // is not supported by our minimum compiler spec (which is pre C++11).\n MyProgramContext* program_context =\n static_cast\u003cMyProgramContext*\u003e(user_data);\n\n // Process create user result...\n (void)program_context;\n },\n &my_program_context);\n}\n```\n\nNext steps\n\nAfter a user signs in for the first time, a new user account is created and\nlinked to the credentials---that is, the user name and password, phone\nnumber, or auth provider information---the user signed in with. This new\naccount is stored as part of your Firebase project, and can be used to identify\na user across every app in your project, regardless of how the user signs in.\n\n- In your apps, you can get the user's basic profile information from the\n [`firebase::auth::User`](/docs/reference/cpp/class/firebase/auth/user) object:\n\n ```c++\n firebase::auth::User user = auth-\u003ecurrent_user();\n if (user.is_valid()) {\n std::string name = user.display_name();\n std::string email = user.email();\n std::string photo_url = user.photo_url();\n // The user's ID, unique to the Firebase project.\n // Do NOT use this value to authenticate with your backend server,\n // if you have one. Use firebase::auth::User::Token() instead.\n std::string uid = user.uid();\n }\n ```\n- In your Firebase Realtime Database and Cloud Storage\n [Security Rules](/docs/database/security/user-security), you can\n get the signed-in user's unique user ID from the `auth` variable,\n and use it to control what data a user can access.\n\nYou can allow users to sign in to your app using multiple authentication\nproviders by [linking auth provider credentials to an\nexisting user account.](/docs/auth/cpp/account-linking)\n\nTo sign out a user, call [`SignOut()`](/docs/reference/cpp/class/firebase/auth/auth#signout): \n\n```c++\nauth-\u003eSignOut();\n```"]]
