Anda dapat mengizinkan pengguna melakukan autentikasi dengan Firebase menggunakan penyedia OAuth, seperti
Yahoo dengan mengintegrasikan Login OAuth umum berbasis web ke aplikasi Anda menggunakan
Firebase SDK untuk menjalankan alur login secara menyeluruh. Alur ini memerlukan penggunaan Firebase SDK berbasis ponsel, sehingga hanya didukung di platform Android dan Apple.
Mendaftarkan project Unity Anda dan mengonfigurasikannya agar dapat menggunakan Firebase.
Jika project Unity Anda telah menggunakan Firebase, berarti project tersebut telah terdaftar dan dikonfigurasi untuk Firebase.
Jika belum memiliki project Unity, Anda dapat mendownload aplikasi contoh.
Tambahkan FirebaseUnity SDK (khususnya, FirebaseAuth.unitypackage) ke
project Unity Anda.
Perlu diperhatikan bahwa penambahan Firebase ke project Unity Anda memerlukan tindakan baik di
Firebase console maupun di project Unity yang terbuka
(misalnya, Anda mendownload file konfigurasi Firebase dari konsol, lalu memindahkannya
ke project Unity).
Mengakses class Firebase.Auth.FirebaseAuth
Class FirebaseAuth adalah gateway untuk semua panggilan API.
Class ini dapat diakses melalui FirebaseAuth.DefaultInstance.
Opsional: Tentukan parameter OAuth kustom tambahan yang ingin dikirim dengan permintaan OAuth.
providerData.CustomParameters=newDictionary<string,string>;// Prompt user to re-authenticate to Yahoo.providerData.CustomParameters.Add("prompt","login");// Localize to French.providerData.CustomParameters.Add("language","fr");
Untuk parameter yang didukung Yahoo, lihat dokumentasi OAuth Yahoo.
Perlu diperhatikan bahwa Anda tidak dapat meneruskan parameter yang diperlukan Firebase dengan
custom_parameters(). Parameter tersebut adalah client_id, redirect_uri, response_type, scope, dan state.
Opsional: Tentukan cakupan OAuth 2.0 tambahan selain profile dan email yang ingin diminta dari penyedia autentikasi. Jika aplikasi Anda memerlukan akses ke data pengguna pribadi dari Yahoo API, Anda harus meminta izin ke Yahoo API di bagian API Permissions di konsol developer Yahoo. Cakupan OAuth yang diminta harus sama persis dengan yang sudah dikonfigurasi sebelumnya dalam izin API aplikasi. Misalnya jika permintaan akses baca/tulis diajukan ke kontak pengguna dan telah dikonfigurasi sebelumnya dalam izin API aplikasi, sdct-w harus diteruskan sebagai ganti dari cakupan OAuth hanya baca sdct-r. Jika tidak, alur akan gagal dan error akan ditampilkan kepada pengguna akhir.
providerData.Scopes=newList<string>();// Request access to Yahoo Mail API.providerData.Scopes.Add("mail-r");// This must be preconfigured in the app's API permissions.providerData.Scopes.Add("sdct-w");
Setelah data penyedia Anda dikonfigurasi, gunakan data tersebut untuk membuat FederatedOAuthProvider.
// Construct a FederatedOAuthProvider for use in Auth methods.Firebase.Auth.FederatedOAuthProviderprovider=newFirebase.Auth.FederatedOAuthProvider();provider.SetProviderData(providerData);
Lakukan autentikasi dengan Firebase menggunakan objek penyedia Auth. Perlu diperhatikan bahwa tidak seperti operasi FirebaseAuth lainnya, tindakan ini akan mengendalikan UI Anda dengan memunculkan tampilan web, tempat pengguna dapat memasukkan kredensial mereka.
Untuk memulai alur login, panggil SignInAndRetrieveDataWithCredentialAsync:
<<../_includes/_sign_in_with_provider_unity.md>>>
Meskipun contoh di atas berfokus pada alur login, Anda juga dapat menautkan penyedia Yahoo ke pengguna yang ada menggunakan LinkWithProviderAsync. Misalnya, Anda dapat menautkan beberapa
penyedia ke pengguna yang sama agar bisa login dengan salah satu penyedia tersebut.
user.LinkWithProviderAsync(provider).ContinueOnMainThread(task=>{if(task.IsCanceled){Debug.LogError("LinkWithProviderAsync was canceled.");return;}if(task.IsFaulted){Debug.LogError("LinkWithProviderAsync encountered an error: "+task.Exception);return;}Firebase.Auth.AuthResultauthResult=task.Result;Firebase.Auth.FirebaseUseruser=authResult.User;Debug.LogFormat("User linked successfully: {0} ({1})",user.DisplayName,user.UserId);});
Pola yang sama dapat digunakan dengan ReauthenticateWithProviderAsync, yang dapat digunakan untuk mengambil kredensial baru untuk operasi sensitif yang memerlukan login terbaru.
user.ReauthenticateWithProviderAsync(provider).ContinueOnMainThread(task=>{if(task.IsCanceled){Debug.LogError("ReauthenticateWithProviderAsync was canceled.");return;}if(task.IsFaulted){Debug.LogError("ReauthenticateWithProviderAsync encountered an error: "+task.Exception);return;}Firebase.Auth.AuthResultauthResult=task.Result;Firebase.Auth.FirebaseUseruser=authResult.User;Debug.LogFormat("User reauthenticated successfully: {0} ({1})",user.DisplayName,user.UserId);});
Lanjutan: Memproses alur login secara manual
Tidak seperti penyedia OAuth lain yang didukung oleh Firebase, seperti Google, Facebook, dan Twitter, yang proses loginnya dapat langsung dilakukan dengan kredensial berbasis token akses OAuth, Firebase Auth tidak mendukung kemampuan yang sama untuk penyedia seperti Yahoo, karena server Firebase Auth tidak dapat memverifikasi audience token akses OAuth Yahoo.
Ini adalah persyaratan keamanan yang penting serta dapat membuat situs dan aplikasi rentan terkena serangan replay, yaitu ketika token akses OAuth Yahoo yang diperoleh untuk satu project (penyerang) dapat digunakan untuk login ke project lain (korban).
Sebagai gantinya, Firebase Auth menyediakan kemampuan untuk menangani seluruh alur OAuth dan pertukaran kode otorisasi menggunakan client ID dan rahasia klien OAuth yang dikonfigurasi dalam Firebase Console. Karena kode otorisasi hanya dapat digunakan bersama dengan client ID atau secret klien tertentu, kode otorisasi yang diperoleh untuk satu project tidak dapat digunakan dengan project lain.
Jika penyedia ini harus digunakan di lingkungan yang tidak didukung, library OAuth pihak ketiga dan autentikasi kustom Firebase perlu digunakan. Library OAuth pihak ketiga diperlukan untuk mengautentikasi penyedia, sedangkan autentikasi kustom Firebase diperlukan untuk menukar kredensial penyedia dengan token kustom.
Langkah berikutnya
Setelah pengguna login untuk pertama kalinya, akun pengguna baru akan dibuat dan ditautkan ke kredensial, yaitu nama pengguna dan sandi, nomor telepon, atau informasi penyedia autentikasi, yang digunakan pengguna tersebut untuk login. Akun baru ini disimpan sebagai bagian dari project Firebase Anda, dan dapat digunakan untuk mengidentifikasi pengguna di setiap aplikasi dalam project, terlepas dari cara pengguna login.
Di aplikasi, Anda bisa mendapatkan informasi profil dasar pengguna dari objek
Firebase.Auth.FirebaseUser:
Firebase.Auth.FirebaseUseruser=auth.CurrentUser;if(user!=null){stringname=user.DisplayName;stringemail=user.Email;System.Uriphoto_url=user.PhotoUrl;// 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 User.TokenAsync() instead.stringuid=user.UserId;}
Di Aturan KeamananFirebase Realtime Database dan Cloud Storage, Anda bisa
mendapatkan ID pengguna unik milik pengguna yang login dari variabel auth,
dan menggunakannya untuk mengontrol data yang dapat diakses oleh pengguna.

Since this flow requires\nthe use of the phone-based Firebase SDKs, it is only supported on Android and\nApple platforms.\n\nBefore you begin\n\nBefore you can use\n[Firebase Authentication](/docs/reference/unity/namespace/firebase/auth),\nyou need to:\n\n- Register your Unity project and configure it to use Firebase.\n\n - If your Unity project already uses Firebase, then it's already\n registered and configured for Firebase.\n\n - If you don't have a Unity project, you can download a\n [sample app](//github.com/google/mechahamster).\n\n- Add the [Firebase Unity SDK](/download/unity) (specifically, `FirebaseAuth.unitypackage`) to\n your Unity project.\n\n| **Find detailed instructions for these initial\n| setup tasks in\n| [Add Firebase to your Unity project](/docs/unity/setup#prerequisites).**\n\nNote that adding Firebase to your Unity project involves tasks both in the\n[Firebase console](//console.firebase.google.com/) and in your open Unity project\n(for example, you download Firebase config files from the console, then move\nthem into your Unity project).\n\nAccess the `Firebase.Auth.FirebaseAuth` class The `FirebaseAuth` class is the gateway for all API calls. It is accessible through [FirebaseAuth.DefaultInstance](/docs/reference/unity/class/firebase/auth/firebase-auth#defaultinstance). \n\n```c#\nFirebase.Auth.FirebaseAuth auth = Firebase.Auth.FirebaseAuth.DefaultInstance;\n```\n\nHandle the sign-in flow with the Firebase SDK\n\nTo handle the sign-in flow with the Firebase SDK, follow these steps:\n\n1. Construct an instance of a `FederatedOAuthProviderData` configured with\n the provider ID appropriate for Yahoo.\n\n Firebase.Auth.FederatedOAuthProviderData providerData =\n new Firebase.Auth.FederatedOAuthProviderData();\n providerData.ProviderId = Firebase.Auth.YahooAuthProvider.ProviderId;\n\n2. **Optional**: Specify additional custom OAuth parameters that you want to\n send with the OAuth request.\n\n providerData.CustomParameters = new Dictionary\u003cstring,string\u003e;\n\n // Prompt user to re-authenticate to Yahoo.\n providerData.CustomParameters.Add(\"prompt\", \"login\");\n\n // Localize to French.\n providerData.CustomParameters.Add(\"language\", \"fr\");\n\n For the parameters Yahoo supports, see the\n [Yahoo OAuth documentation](https://developer.yahoo.com/oauth2/guide/openid_connect/getting_started.html).\n Note that you can't pass Firebase-required parameters with\n `custom_parameters()`. These parameters are **client_id** ,\n **redirect_uri** , **response_type** , **scope** and **state**.\n3. **Optional** : Specify additional OAuth 2.0 scopes beyond `profile` and\n `email` that you want to request from the authentication provider. If your\n application requires access to private user data from Yahoo APIs, you'll\n need to request permissions to Yahoo APIs under **API Permissions** in the\n Yahoo developer console. Requested OAuth scopes must be exact matches to the\n preconfigured ones in the app's API permissions. For example if, read/write\n access is requested to user contacts and preconfigured in the app's API\n permissions, `sdct-w` has to be passed instead of the readonly OAuth scope\n `sdct-r`. Otherwise,the flow will fail and an error would be shown to the\n end user.\n\n providerData.Scopes = new List\u003cstring\u003e();\n\n // Request access to Yahoo Mail API.\n providerData.Scopes.Add(\"mail-r\");\n // This must be preconfigured in the app's API permissions.\n providerData.Scopes.Add(\"sdct-w\");\n\n To learn more, refer to the\n [Yahoo scopes documentation](https://developer.yahoo.com/oauth2/guide/yahoo_scopes/).\n4. Once your provider data has been configured, use it to create a\n FederatedOAuthProvider.\n\n // Construct a FederatedOAuthProvider for use in Auth methods.\n Firebase.Auth.FederatedOAuthProvider provider =\n new Firebase.Auth.FederatedOAuthProvider();\n provider.SetProviderData(providerData);\n\n5. Authenticate with Firebase using the Auth provider object. Note that unlike\n other FirebaseAuth operations, this will take control of your UI by popping\n up a web view in which the user can enter their credentials.\n\n To start the sign in flow, call `SignInAndRetrieveDataWithCredentialAsync`:\n\n\\\u003c\\\u003c../_includes/_sign_in_with_provider_unity.md\\\u003e\\\u003e\\\u003e\n\n1. While the above examples focus on sign-in flows, you also have the\n ability to link a Yahoo provider to an existing user using\n `LinkWithProviderAsync`. For example, you can link multiple\n providers to the same user allowing them to sign in with either.\n\n user.LinkWithProviderAsync(provider).ContinueOnMainThread(task =\u003e {\n if (task.IsCanceled) {\n Debug.LogError(\"LinkWithProviderAsync was canceled.\");\n return;\n }\n if (task.IsFaulted) {\n Debug.LogError(\"LinkWithProviderAsync encountered an error: \"\n + task.Exception);\n return;\n }\n\n Firebase.Auth.AuthResult authResult = task.Result;\n Firebase.Auth.FirebaseUser user = authResult.User;\n Debug.LogFormat(\"User linked successfully: {0} ({1})\",\n user.DisplayName, user.UserId);\n });\n\n2. The same pattern can be used with `ReauthenticateWithProviderAsync` which\n can be used to retrieve fresh credentials for sensitive operations that\n require recent login.\n\n user.ReauthenticateWithProviderAsync(provider).ContinueOnMainThread(task =\u003e {\n if (task.IsCanceled) {\n Debug.LogError(\"ReauthenticateWithProviderAsync was canceled.\");\n return;\n }\n if (task.IsFaulted) {\n Debug.LogError(\n \"ReauthenticateWithProviderAsync encountered an error: \" +\n task.Exception);\n return;\n }\n\n Firebase.Auth.AuthResult authResult = task.Result;\n Firebase.Auth.FirebaseUser user = authResult.User;\n Debug.LogFormat(\"User reauthenticated successfully: {0} ({1})\",\n user.DisplayName, user.UserId);\n });\n\nAdvanced: Handle the sign-in flow manually\n\nUnlike other OAuth providers supported by Firebase such as Google, Facebook,\nand Twitter, where sign-in can directly be achieved with OAuth access token\nbased credentials, Firebase Auth does not support the same capability for\nproviders such as Yahoo due to the inability of the Firebase\nAuth server to verify the audience of Yahoo OAuth access tokens.\nThis is a critical security requirement and could expose applications and\nwebsites to replay attacks where a Yahoo OAuth access token obtained for\none project (attacker) can be used to sign in to another project (victim).\nInstead, Firebase Auth offers the ability to handle the entire OAuth flow and\nthe authorization code exchange using the OAuth client ID and secret\nconfigured in the Firebase Console. As the authorization code can only be used\nin conjunction with a specific client ID/secret, an authorization code\nobtained for one project cannot be used with another.\n\nIf these providers are required to be used in unsupported environments, a\nthird party OAuth library and\n[Firebase custom authentication](../admin/create-custom-tokens)\nwould need to be used. The former is needed to authenticate with the provider\nand the latter to exchange the provider's credential for a custom token.\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.FirebaseUser`](/docs/reference/unity/class/firebase/auth/firebase-user) object:\n\n ```c#\n Firebase.Auth.FirebaseUser user = auth.CurrentUser;\n if (user != null) {\n string name = user.DisplayName;\n string email = user.Email;\n System.Uri photo_url = user.PhotoUrl;\n // The user's Id, unique to the Firebase project.\n // Do NOT use this value to authenticate with your backend server, if you\n // have one; use User.TokenAsync() instead.\n string uid = user.UserId;\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/unity/account-linking)\n\nTo sign out a user, call [`SignOut()`](/docs/reference/unity/class/firebase/auth/firebase-auth#signout): \n\n```c#\nauth.SignOut();\n```"]]
