設定用戶端

Java

1. 匯入必要的程式庫。

   import static java.nio.charset.StandardCharsets.UTF_8; import com.google.api.client.auth.oauth2.Credential; import com.google.api.client.extensions.java6.auth.oauth2.AuthorizationCodeInstalledApp; import com.google.api.client.extensions.jetty.auth.oauth2.LocalServerReceiver; import com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow; import com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets; import com.google.api.client.googleapis.util.Utils; import com.google.api.services.displayvideo.v4.DisplayVideo; import com.google.api.services.displayvideo.v4.DisplayVideo.Advertisers; import com.google.api.services.displayvideo.v4.model.Advertiser; import com.google.api.services.displayvideo.v4.model.ListAdvertisersResponse; import java.io.Reader; import java.nio.file.Files; import java.nio.file.Paths; 

2. 載入用戶端密鑰檔案並產生授權憑證。

   首次執行這個步驟時，系統會要求您在瀏覽器中接受授權提示。接受前，請確認您已登入具有 Display & Video 360 存取權的 Google 帳戶。您的應用程式將獲准代表目前登入的任何帳戶存取資料。如要進一步瞭解 Display & Video 360 使用者權限，請參閱「授權要求」指南。

   // Read client secrets file. GoogleClientSecrets clientSecrets; try (Reader reader = Files.newBufferedReader(Paths.get(path-to-client-secrets-file), UTF_8)) {   clientSecrets = GoogleClientSecrets.load(Utils.getDefaultJsonFactory(), reader); }  // Generate authorization credentials. // Set up the authorization code flow. GoogleAuthorizationCodeFlow flow =     new GoogleAuthorizationCodeFlow.Builder(         Utils.getDefaultTransport(),         Utils.getDefaultJsonFactory(),         clientSecrets,         oauth-scopes)     .build();  Credential credential =     new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user"); 

3. 建立授權的 API 用戶端。

   // Create authorized API client. DisplayVideo service =     new DisplayVideo.Builder(credential.getTransport(), credential.getJsonFactory(), credential)         .setApplicationName("displayvideo-java-installed-app-sample")         .build(); 

4. 執行作業。

   // Perform an operation. // Retrieve and print the first ten advertisers under a partner. ListAdvertisersResponse response =     service         .advertisers()         .list()         .setPartnerId(partner-id)         .setPageSize(10)         .execute(); if (response.getAdvertisers().size() > 0) {   for (int i = 0; i < response.getAdvertisers().size(); i++) {     System.out.printf(         "ID: %s Display Name: %s%n",         response.getAdvertisers().get(i).getAdvertiserId(),         response.getAdvertisers().get(i).getDisplayName());   } } else {   System.out.print("No advertisers found."); } 

Python

1. 匯入必要的程式庫。

   from google_auth_oauthlib.flow import InstalledAppFlow from googleapiclient import discovery 

2. 載入用戶端密鑰檔案並產生授權憑證。

   首次執行這個步驟時，系統會要求您在瀏覽器中接受授權提示。接受前，請確認您已登入具有 Display & Video 360 存取權的 Google 帳戶。您的應用程式將獲准代表目前登入的任何帳戶存取資料。如要進一步瞭解 Display & Video 360 使用者權限，請參閱「授權要求」指南。

   # Set up a flow object to create the credentials using the # client secrets file and OAuth scopes. credentials = InstalledAppFlow.from_client_secrets_file(     path-to-client-secrets-file, oauth-scopes).run_local_server() 

3. 建立授權的 API 用戶端。

   # Build the discovery document URL. discovery_url = f'https://displayvideo.googleapis.com/$discovery/rest?version=v4'  # Build the API service. service = discovery.build(     'displayvideo',     'v4',     discoveryServiceUrl=discovery_url,     credentials=credentials) 

4. 執行作業。

   # Build advertisers.list request. request = service.advertisers().list(     partnerId=partner-id, pageSize='10')  # Execute request. response = request.execute()  # Print response. if len(response['advertisers']) > 0:   for advertiser in response['advertisers']:     print(f'ID: {advertiser["advertiserId"]} Display Name: {advertiser["displayName"]}') else:   print('No advertisers found.') 

PHP

這個範例假設您會使用內建的網路伺服器執行 PHP，並已將憑證設為重新導向至相關網頁。舉例來說，您可以使用下列指令和憑證，在 index.php 檔案中執行這段程式碼，並在驗證後將其重新導向至 http://localhost:8000：

php -S localhost:8000 -t ./

1. 下載並安裝 Google API PHP 用戶端程式庫。

   建議使用 Composer：

   composer require google/apiclient:^2.18.2 google/apiclient-services:=0.396.0

   安裝完成後，請務必加入自動載入器：

   require_once '/path/to/your-project/vendor/autoload.php'; 

2. 建立 Google_Client 物件。

   $client = new Google_Client(); 

3. 設定用戶端、重新導向至驗證網址 (如有必要)，然後擷取存取權杖。

   首次執行這個步驟時，系統會要求您在瀏覽器中接受授權提示。接受前，請確認您已登入具有 Display & Video 360 存取權的 Google 帳戶。您的應用程式將獲准代表目前登入的任何帳戶存取資料。如要進一步瞭解 Display & Video 360 使用者權限，請參閱「授權要求」指南。

   // Set up the client. $client->setApplicationName('DV360 API PHP Samples'); $client->addScope(oauth-scope); $client->setAccessType('offline'); $client->setAuthConfigFile(path-to-client-secrets-file);  // If the code is passed, authenticate. If not, redirect to authentication page. if (isset($_GET['code'])) {   $client->authenticate($_GET['code']); } else {   $authUrl = $client->createAuthUrl();   header('Location: ' . $authUrl); }  // Exchange authorization code for an access token. $accessToken = $client->getAccessToken(); $client->setAccessToken($accessToken); 

4. 為 Display & Video 360 API 服務建構用戶端。

   $service = new Google_Service_DisplayVideo($client); 

5. 執行作業。

   // Configure params for the advertisers.list request. $optParams = array('pageSize' => 10, 'partnerId' => partner-id);  // Execute the request. $result = $service->advertisers->listAdvertisers($optParams);  // Print the retrieved advertisers. if (!empty($result->getAdvertisers())) {   print('<pre>');   foreach ($result->getAdvertisers() as $advertiser) {     printf('<p>ID: %s, Display Name: %s</p>', $advertiser->advertiserId, $advertiser->displayName);   }   print('</pre>'); } else {   print '<p>No advertisers found.</p>'; }
