配置客户端

创建 OAuth 2.0 凭据并安装客户端库后，您便可以开始使用 Display & Video 360 API 了。按照以下快速入门，了解如何授权、配置客户端并发出第一个请求。

Java

导入必要的库。

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;

加载客户端密钥文件并生成授权凭据。

首次执行此步骤时，系统会要求您接受浏览器中的授权提示。接受之前，请务必使用可访问 Display & Video 360 的 Google 账号登录。您的应用将获得授权，能够代表当前登录的帐号访问数据。如需详细了解 Display & Video 360 用户权限，请参阅我们的授权请求指南。

// 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");

创建已获授权的 API 客户端。

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

执行操作。

// 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

导入必要的库。

from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient import discovery

加载客户端密钥文件并生成授权凭据。

首次执行此步骤时，系统会要求您接受浏览器中的授权提示。接受之前，请务必使用可访问 Display & Video 360 的 Google 账号登录。您的应用将获得授权，能够代表当前登录的帐号访问数据。如需详细了解 Display & Video 360 用户权限，请参阅我们的授权请求指南。
```
# 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()
```

创建已获授权的 API 客户端。

# 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)

执行操作。

# 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

此示例假定您使用内置 Web 服务器运行 PHP，并且已将凭据配置为重定向到相关网页。例如，在 index.php 文件中，可使用以下命令以及配置为在身份验证后重定向到 http://localhost:8000 的凭据运行此代码：

php -S localhost:8000 -t ./

下载并安装 Google API PHP 客户端。

首选方法是使用 Composer：

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

安装后，请务必添加自动加载器：

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

创建一个 Google_Client 对象。
```
$client = new Google_Client();
```

设置客户端，根据需要重定向到身份验证网址，并检索访问令牌。

// 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);

为 Display & Video 360 API 服务构建客户端。

$service = new Google_Service_DisplayVideo($client);

执行操作。

// 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>';
}
