設定用戶端

建立 OAuth 2.0 憑證安裝用戶端程式庫後,您就可以開始使用 Display & Video 360 API。請參閱下列快速入門導覽課程,瞭解如何授權、設定用戶端及提出您的第一個要求。

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.v3.DisplayVideo;
    import com.google.api.services.displayvideo.v3.DisplayVideo.Advertisers;
    import com.google.api.services.displayvideo.v3.model.Advertiser;
    import com.google.api.services.displayvideo.v3.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。

    第一次執行這個步驟時,系統會要求您接受瀏覽器的授權提示。接受之前,請確認您已登入可存取 Display & Video 360 的 Google 帳戶。您的應用程式將有權代表目前登入的帳戶存取資料。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。

    第一次執行這個步驟時,系統會要求您接受瀏覽器的授權提示。接受之前,請確認您已登入可存取 Display & Video 360 的 Google 帳戶。您的應用程式將有權代表目前登入的帳戶存取資料。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=v3'
    
    # Build the API service.
    service = discovery.build(
        'displayvideo',
        'v3',
        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

本範例假設您使用內建網路伺服器執行 PHP,並將憑證設定為重新導向至相關網頁。舉例來說,index.php 檔案中的這段程式碼和設定憑證可在驗證後重新導向至 http://localhost:8000

php -S localhost:8000 -t ./

  1. 下載並安裝 Google API PHP 用戶端。

    建議使用 Composer

    composer require google/apiclient:^2.15.1 google/apiclient-services:=0.332.0
    

    安裝後,請務必加入自動載入程式:

    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、視需要重新導向至驗證網址,以及擷取存取權杖。

    第一次執行這個步驟時,系統會要求您接受瀏覽器的授權提示。接受之前,請確認您已登入可存取 Display & Video 360 的 Google 帳戶。您的應用程式將有權代表目前登入的帳戶存取資料。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>';
    }
