با رویه قبلی افزودن ورود به سیستم ، برنامه شما فقط در سمت کلاینت کاربر را احراز هویت می کند. در این صورت، فقط زمانی که کاربر به طور فعال از برنامه شما استفاده می کند، می توانید به API های Google دسترسی داشته باشید. اگر میخواهید سرورهای شما قادر به برقراری تماسهای Google API از طرف کاربران باشند - احتمالاً در زمانی که آنها آفلاین هستند - سرور شما به یک نشانه دسترسی نیاز دارد.
یک شناسه سرویس گیرنده برنامه وب OAuth 2.0 برای سرور باطن خود ایجاد کنید. این شناسه مشتری با شناسه مشتری برنامه شما متفاوت است. میتوانید یک شناسه کلاینت برای سرور خود در Google API Console پیدا کنید یا ایجاد کنید.
شناسه مشتری سرور خود را به روش requestServerAuthCode ارسال کنید.
// Configure sign-in to request offline access to the user's ID, basic// profile, and Google Drive. The first time you request a code you will// be able to exchange it for an access token and refresh token, which// you should store. In subsequent calls, the code will only result in// an access token. By asking for profile access (through// DEFAULT_SIGN_IN) you will also get an ID Token as a result of the// code exchange.StringserverClientId=getString(R.string.server_client_id);GoogleSignInOptionsgso=newGoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestScopes(newScope(Scopes.DRIVE_APPFOLDER)).requestServerAuthCode(serverClientId).requestEmail().build();
در سرور پشتیبان برنامه خود، کد احراز هویت را برای دسترسی و بازخوانی نشانه ها مبادله کنید. از نشانه دسترسی برای فراخوانی APIهای Google از طرف کاربر استفاده کنید و به صورت اختیاری، رمز بازخوانی را ذخیره کنید تا زمانی که نشانه دسترسی منقضی شود، یک نشانه دسترسی جدید به دست آورید.
اگر درخواست دسترسی به نمایه را داشته باشید، یک رمز شناسایی نیز دریافت میکنید که حاوی اطلاعات اولیه نمایه کاربر است.

Credential Manager\n| supports passkey, password, and federated identity authentication (such as\n| Sign-in with Google), stronger security, and a more consistent user\n| experience.\n|\n| **For Wear developers:** Credential Manager will be supported in Wear OS\n| 5.1 and later on selected watches. Developers actively supporting Wear OS 3, 4\n| and 5.0 devices with Sign in with Google should continue using Google Sign-in\n| for Android for your Wear applications. Sign in with Google support will be\n| available on Credential Manager APIs for these versions of WearOS at a later\n| date.\n\nWith the earlier [Add Sign-In](/identity/legacy/gsi/legacy-sign-in#add_the_google_sign-in_button_to_your_app)\nprocedure, your app authenticates the user on the client side only; in that case,\nyou can access the Google APIs only while the user is actively using your app.\nIf you want your servers to be able to make Google API calls on behalf of\nusers---possibly while they are offline---your server requires an access\ntoken.\n\nBefore you begin\n----------------\n\n- Configure a project in Android Studio\n- [Add a Google Sign-In button to your app](/identity/legacy/gsi/legacy-sign-in)\n- Create an OAuth 2.0 web application client ID for your backend server. This client ID is different from your app's client ID. You can find or create a client ID for your server in the [Google API Console](https://console.cloud.google.com/apis/credentials).\n\nEnable server-side API access for your app\n------------------------------------------\n\n1. When you [configure Google Sign-In](/identity/legacy/gsi/legacy-sign-in#configure_google_sign-in_and_the_googlesigninclient_object),\n build the `GoogleSignInOptions` object with the [`requestServerAuthCode`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInOptions.Builder.html#requestServerAuthCode(java.lang.String))\n method and specify the scopes that your app's backend needs to access with\n the \\[`requestScopes`\\]\\[55\\]\n method.\n\n Pass your server's client ID to the `requestServerAuthCode` method. \n\n ```scilab\n // Configure sign-in to request offline access to the user's ID, basic\n // profile, and Google Drive. The first time you request a code you will\n // be able to exchange it for an access token and refresh token, which\n // you should store. In subsequent calls, the code will only result in\n // an access token. By asking for profile access (through\n // DEFAULT_SIGN_IN) you will also get an ID Token as a result of the\n // code exchange.\n String serverClientId = getString(R.string.server_client_id);\n GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)\n .requestScopes(new Scope(Scopes.DRIVE_APPFOLDER))\n .requestServerAuthCode(serverClientId)\n .requestEmail()\n .build();\n ```\n2. After the user [successfully signs in](/identity/legacy/gsi/legacy-sign-in#start_the_sign-in_flow),\n get an auth code for the user with [`getServerAuthCode`](https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInAccount.html#getServerAuthCode()):\n\n ```text\n Task\u003cGoogleSignInAccount\u003e task = GoogleSignIn.getSignedInAccountFromIntent(data);\n try {\n GoogleSignInAccount account = task.getResult(ApiException.class);\n String authCode = account.getServerAuthCode();\n\n // Show signed-un UI\n updateUI(account);\n\n // TODO(developer): send code to server and exchange for access/refresh/ID tokens\n } catch (ApiException e) {\n Log.w(TAG, \"Sign-in failed\", e);\n updateUI(null);\n }\n ```\n3. Send the auth code to your app's backend using HTTPS POST:\n\n HttpPost httpPost = new HttpPost(\"https://yourbackend.example.com/authcode\");\n\n try {\n List\u003cNameValuePair\u003e nameValuePairs = new ArrayList\u003cNameValuePair\u003e(1);\n nameValuePairs.add(new BasicNameValuePair(\"authCode\", authCode));\n httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));\n\n HttpResponse response = httpClient.execute(httpPost);\n int statusCode = response.getStatusLine().getStatusCode();\n final String responseBody = EntityUtils.toString(response.getEntity());\n } catch (ClientProtocolException e) {\n Log.e(TAG, \"Error sending auth code to backend.\", e);\n } catch (IOException e) {\n Log.e(TAG, \"Error sending auth code to backend.\", e);\n }\n\n4. On your app's backend server, exchange the auth code for access and refresh\n tokens. Use the access token to call Google APIs on behalf of the user and,\n optionally, store the refresh token to acquire a new access token when the\n access token expires.\n\n If you requested profile access, you also get an ID token that contains\n basic profile information for the user.\n\n For example: \n\n ##### Java\n\n ```java\n // (Receive authCode via HTTPS POST)\n\n if (request.getHeader(\"X-Requested-With\") == null) {\n // Without the `X-Requested-With` header, this request could be forged. Aborts.\n }\n\n // Set path to the Web application client_secret_*.json file you downloaded from the\n // Google API Console: https://console.cloud.google.com/apis/credentials\n // You can also find your Web application client ID and client secret from the\n // console and specify them directly when you create the GoogleAuthorizationCodeTokenRequest\n // object.\n String CLIENT_SECRET_FILE = \"/path/to/client_secret.json\";\n\n // Exchange auth code for access token\n GoogleClientSecrets clientSecrets =\n GoogleClientSecrets.load(\n JacksonFactory.getDefaultInstance(), new FileReader(CLIENT_SECRET_FILE));\n GoogleTokenResponse tokenResponse =\n new GoogleAuthorizationCodeTokenRequest(\n new NetHttpTransport(),\n JacksonFactory.getDefaultInstance(),\n \"https://oauth2.googleapis.com/token\",\n clientSecrets.getDetails().getClientId(),\n clientSecrets.getDetails().getClientSecret(),\n authCode,\n REDIRECT_URI) // Specify the same redirect URI that you use with your web\n // app. If you don't have a web version of your app, you can\n // specify an empty string.\n .execute();\n\n String accessToken = tokenResponse.getAccessToken();\n\n // Use access token to call API\n GoogleCredential credential = new GoogleCredential().setAccessToken(accessToken);\n Drive drive =\n new Drive.Builder(new NetHttpTransport(), JacksonFactory.getDefaultInstance(), credential)\n .setApplicationName(\"Auth Code Exchange Demo\")\n .build();\n File file = drive.files().get(\"appfolder\").execute();\n\n // Get profile info from ID token\n GoogleIdToken idToken = tokenResponse.parseIdToken();\n GoogleIdToken.Payload payload = idToken.getPayload();\n String userId = payload.getSubject(); // Use this value as a key to identify a user.\n String email = payload.getEmail();\n boolean emailVerified = Boolean.valueOf(payload.getEmailVerified());\n String name = (String) payload.get(\"name\");\n String pictureUrl = (String) payload.get(\"picture\");\n String locale = (String) payload.get(\"locale\");\n String familyName = (String) payload.get(\"family_name\");\n String givenName = (String) payload.get(\"given_name\");\n ```\n\n ##### Python\n\n ```python\n from apiclient import discovery\n import httplib2\n from oauth2client import client\n\n # (Receive auth_code by HTTPS POST)\n\n # If this request does not have `X-Requested-With` header, this could be a CSRF\n if not request.headers.get('X-Requested-With'):\n abort(403)\n\n # Set path to the Web application client_secret_*.json file you downloaded from the\n # Google API Console: https://console.cloud.google.com/apis/credentials\n CLIENT_SECRET_FILE = '/path/to/client_secret.json'\n\n # Exchange auth code for access token, refresh token, and ID token\n credentials = client.credentials_from_clientsecrets_and_code(\n CLIENT_SECRET_FILE,\n ['https://www.googleapis.com/auth/drive.appdata', 'profile', 'email'],\n auth_code)\n\n # Call Google API\n http_auth = credentials.authorize(httplib2.Http())\n drive_service = discovery.build('drive', 'v3', http=http_auth)\n appfolder = drive_service.files().get(fileId='appfolder').execute()\n\n # Get profile info from ID token\n userid = credentials.id_token['sub']\n email = credentials.id_token['email']\n ```\n\n\\[55\\]: https://developers.google.com/android/reference/com/google/android/gms/auth/api/signin/GoogleSignInOptions.Builder.html#requestScopes(com.google.android.gms.common.api.Scope, com.google.android.gms.common.api.Scope...)"]]
