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>';
   }
