进行 API 调用

本指南需要在 之前的步骤。如果您符合以下条件，请从简介开始

本指南还使用了刷新令牌， 对 Google Ads 账号的访问权限，让您的应用通过一次性设置完成以下操作： 对账号进行离线 API 调用，而无需任何进一步的用户干预。 您可以使用刷新令牌构建这两种离线工作流，例如 Cron 作业 或数据流水线以及交互式工作流，例如 Web 应用或移动应用。

提取刷新令牌

Google Ads API 使用 OAuth 2.0 作为授权机制。默认情况下 2.0 身份验证会颁发访问令牌，该令牌会在限定的 。要自动续订访问令牌，您应该发出刷新 令牌。

  1. 通过运行 oauth2l 工具：

    oauth2l fetch --credentials credentials.json --scope adwords \
    --output_format refresh_token

    credentials.json 文件来自之前的 步骤。

  2. oauth2l 命令会在新的浏览器中打开 Google 账号登录窗口 窗口，并引导您完成 OAuth 2.0 身份验证步骤。

    确保使用您在步骤中的电子邮件地址登录 识别了您的登录客户 ID。

    如果您的应用未经验证，您可能会看到警告屏幕。在这种情况下， 您可以放心点击显示高级信息链接，然后点击 前往 PROJECT_NAME（未验证）选项。

  3. 验证作用域后，请点击 继续按钮。

    浏览器中会显示包含以下文本的提示：

    Authorization code granted. Please close this tab.

    oauth2l 命令会输出以下 JSON 代码段：

    {
  "client_id": "******.apps.googleusercontent.com",
  "client_secret": "******",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "refresh_token": "******",
  "type": "authorized_user"
}

进行 API 调用

选择您选择的客户端，了解如何进行 API 调用：

Java

客户端库工件会发布到 Maven central 代码库。将 将客户端库作为依赖项添加到项目中，如下所示：

Maven 依赖项为：

<dependency>
  <groupId>com.google.api-ads</groupId>
  <artifactId>google-ads</artifactId>
  <version>33.0.0</version>
</dependency>

Gradle 依赖项为：

implementation 'com.google.api-ads:google-ads:33.0.0'

创建一个包含以下内容的 ~/ads.properties 文件。

api.googleads.clientId=INSERT_CLIENT_ID_HERE
api.googleads.clientSecret=INSERT_CLIENT_SECRET_HERE
api.googleads.refreshToken=INSERT_REFRESH_TOKEN_HERE
api.googleads.developerToken=INSERT_DEVELOPER_TOKEN_HERE
api.googleads.loginCustomerId=INSERT_LOGIN_CUSTOMER_ID_HERE

创建一个 GoogleAdsClient 对象，如下所示：

GoogleAdsClient googleAdsClient = null;
try {
  googleAdsClient = GoogleAdsClient.newBuilder().fromPropertiesFile().build();
} catch (FileNotFoundException fnfe) {
  System.err.printf(
      "Failed to load GoogleAdsClient configuration from file. Exception: %s%n",
      fnfe);
  System.exit(1);
} catch (IOException ioe) {
  System.err.printf("Failed to create GoogleAdsClient. Exception: %s%n", ioe);
  System.exit(1);
}

接下来，使用 GoogleAdsService.SearchStream 方法来获取您账号中的广告系列。本指南不涵盖 报告的详细信息。

  private void runExample(GoogleAdsClient googleAdsClient, long customerId) {
  try (GoogleAdsServiceClient googleAdsServiceClient =
      googleAdsClient.getLatestVersion().createGoogleAdsServiceClient()) {
    String query = "SELECT campaign.id, campaign.name FROM campaign ORDER BY campaign.id";
    // Constructs the SearchGoogleAdsStreamRequest.
    SearchGoogleAdsStreamRequest request =
        SearchGoogleAdsStreamRequest.newBuilder()
            .setCustomerId(Long.toString(customerId))
            .setQuery(query)
            .build();

    // Creates and issues a search Google Ads stream request that will retrieve all campaigns.
    ServerStream<SearchGoogleAdsStreamResponse> stream =
        googleAdsServiceClient.searchStreamCallable().call(request);

    // Iterates through and prints all of the results in the stream response.
    for (SearchGoogleAdsStreamResponse response : stream) {
      for (GoogleAdsRow googleAdsRow : response.getResultsList()) {
        System.out.printf(
            "Campaign with ID %d and name '%s' was found.%n",
            googleAdsRow.getCampaign().getId(), googleAdsRow.getCampaign().getName());
      }
    }
  }
}
GetCampaigns.java

C#

客户端库软件包会发布到 Nuget.org 代码库。首先添加一个 对 Google.Ads.GoogleAds 软件包的 nuget 引用。

dotnet add package Google.Ads.GoogleAds --version 18.1.0

创建具有相关设置的 GoogleAdsConfig 对象，并将其用于 创建一个 GoogleAdsClient 对象。

GoogleAdsConfig config = new GoogleAdsConfig()
{
    DeveloperToken = "******",
    OAuth2Mode = "APPLICATION",
    OAuth2ClientId = "******.apps.googleusercontent.com",
    OAuth2ClientSecret = "******",
    OAuth2RefreshToken = "******",
    LoginCustomerId = ******
};
GoogleAdsClient client = new GoogleAdsClient(config);

接下来，使用 GoogleAdsService.SearchStream 方法获取您账号中的广告系列。本指南不涵盖 报告的详细信息。

  public void Run(GoogleAdsClient client, long customerId)
{
    // Get the GoogleAdsService.
    GoogleAdsServiceClient googleAdsService = client.GetService(
        Services.V17.GoogleAdsService);

    // Create a query that will retrieve all campaigns.
    string query = @"SELECT
                    campaign.id,
                    campaign.name,
                    campaign.network_settings.target_content_network
                FROM campaign
                ORDER BY campaign.id";

    try
    {
        // Issue a search request.
        googleAdsService.SearchStream(customerId.ToString(), query,
            delegate (SearchGoogleAdsStreamResponse resp)
            {
                foreach (GoogleAdsRow googleAdsRow in resp.Results)
                {
                    Console.WriteLine("Campaign with ID {0} and name '{1}' was found.",
                        googleAdsRow.Campaign.Id, googleAdsRow.Campaign.Name);
                }
            }
        );
    }
    catch (GoogleAdsException e)
    {
        Console.WriteLine("Failure:");
        Console.WriteLine($"Message: {e.Message}");
        Console.WriteLine($"Failure: {e.Failure}");
        Console.WriteLine($"Request ID: {e.RequestId}");
        throw;
    }
}
GetCampaigns.cs

PHP

客户端库软件包会发布到Packagist 代码库。更改为 项目的根目录，然后运行以下命令以安装 您的库的vendor/目录中 项目的根目录下。

[OAUTH2]
clientId = "INSERT_OAUTH2_CLIENT_ID_HERE"
clientSecret = "INSERT_OAUTH2_CLIENT_SECRET_HERE"
refreshToken = "INSERT_OAUTH2_REFRESH_TOKEN_HERE"

创建 GoogleAdsClient 对象的实例。

$oAuth2Credential = (new OAuth2TokenBuilder())
    ->fromFile('/path/to/google_ads_php.ini')
    ->build();

$googleAdsClient = (new GoogleAdsClientBuilder())
    ->fromFile('/path/to/google_ads_php.ini')
    ->withOAuth2Credential($oAuth2Credential)
    ->build();

接下来，使用 GoogleAdsService.SearchStream 方法获取您账号中的广告系列。本指南不涵盖 报告的详细信息。

  public static function runExample(GoogleAdsClient $googleAdsClient, int $customerId)
{
    $googleAdsServiceClient = $googleAdsClient->getGoogleAdsServiceClient();
    // Creates a query that retrieves all campaigns.
    $query = 'SELECT campaign.id, campaign.name FROM campaign ORDER BY campaign.id';
    // Issues a search stream request.
    /** @var GoogleAdsServerStreamDecorator $stream */
    $stream = $googleAdsServiceClient->searchStream(
        SearchGoogleAdsStreamRequest::build($customerId, $query)
    );

    // Iterates over all rows in all messages and prints the requested field values for
    // the campaign in each row.
    foreach ($stream->iterateAllElements() as $googleAdsRow) {
        /** @var GoogleAdsRow $googleAdsRow */
        printf(
            "Campaign with ID %d and name '%s' was found.%s",
            $googleAdsRow->getCampaign()->getId(),
            $googleAdsRow->getCampaign()->getName(),
            PHP_EOL
        );
    }
}
GetCampaigns.php

Python

客户端库在 PyPI 上分发 可使用 pip 命令安装 如下所示：

python -m pip install google-ads==21.3.0

复制google-ads.yaml 文件，并修改该文件以包含您的凭据。

client_id: INSERT_OAUTH2_CLIENT_ID_HERE
client_secret: INSERT_OAUTH2_CLIENT_SECRET_HERE
refresh_token: INSERT_REFRESH_TOKEN_HERE
developer_token: INSERT_DEVELOPER_TOKEN_HERE
login_customer_id: INSERT_LOGIN_CUSTOMER_ID_HERE

通过调用GoogleAdsClient GoogleAdsClient.load_from_storage 方法。将路径传递到 在调用该方法时，将 google-ads.yaml 以字符串形式添加到该方法：

from google.ads.googleads.client import GoogleAdsClient
client = GoogleAdsClient.load_from_storage("path/to/google-ads.yaml")

接下来，使用 GoogleAdsService.SearchStream 方法获取您账号中的广告系列。本指南不涵盖 报告的详细信息。

def main(client, customer_id):
    ga_service = client.get_service("GoogleAdsService")

    query = """
        SELECT
          campaign.id,
          campaign.name
        FROM campaign
        ORDER BY campaign.id"""

    # Issues a search request using streaming.
    stream = ga_service.search_stream(customer_id=customer_id, query=query)

    for batch in stream:
        for row in batch.results:
            print(
                f"Campaign with ID {row.campaign.id} and name "
                f'"{row.campaign.name}" was found.'
            )
get_campaigns.py

Ruby

客户端库的 Ruby gem 会发布到 Rubygems gem 托管网站。推荐方法 使用 Bundler在 Gemfile 中添加一行代码：

gem 'google-ads-googleads', '~> 30.0.0'

然后运行以下命令：

bundle install

复制 google_ads_config.rb 文件，并修改该文件以包含您的凭据。

Google::Ads::GoogleAds::Config.new do |c|
  c.client_id = 'INSERT_CLIENT_ID_HERE'
  c.client_secret = 'INSERT_CLIENT_SECRET_HERE'
  c.refresh_token = 'INSERT_REFRESH_TOKEN_HERE'
  c.developer_token = 'INSERT_DEVELOPER_TOKEN_HERE'
  c.login_customer_id = 'INSERT_LOGIN_CUSTOMER_ID_HERE'
end

创建一个 GoogleAdsClient 实例，方法是将路径传递给您存放它的位置 文件。

client = Google::Ads::GoogleAds::GoogleAdsClient.new('path/to/google_ads_config.rb')

接下来，使用 GoogleAdsService.SearchStream 方法获取您账号中的广告系列。本指南不涵盖 报告的详细信息。

  def get_campaigns(customer_id)
  # GoogleAdsClient will read a config file from
  # ENV['HOME']/google_ads_config.rb when called without parameters
  client = Google::Ads::GoogleAds::GoogleAdsClient.new

  responses = client.service.google_ads.search_stream(
    customer_id: customer_id,
    query: 'SELECT campaign.id, campaign.name FROM campaign ORDER BY campaign.id',
  )

  responses.each do |response|
    response.results.each do |row|
      puts "Campaign with ID #{row.campaign.id} and name '#{row.campaign.name}' was found."
    end
  end
end
get_campaigns.rb

Perl

该库的发行版本 CPAN。首先克隆 google-ads-perl 代码库中。

git clone https://github.com/googleads/google-ads-perl.git

切换到 google-ads-perl 目录，然后在以下位置运行以下命令： 命令提示符安装使用该库所需的所有依赖项。

cd google-ads-perl
cpan install Module::Build
perl Build.PL
perl Build installdeps

复制 googleads.properties 文件，并修改该文件以包含您的凭据。

clientId=INSERT_OAUTH2_CLIENT_ID_HERE
clientSecret=INSERT_OAUTH2_CLIENT_SECRET_HERE
refreshToken=INSERT_OAUTH2_REFRESH_TOKEN_HERE
developerToken=INSERT_DEVELOPER_TOKEN_HERE
loginCustomerId=INSERT_LOGIN_CUSTOMER_ID_HERE

通过传递保存此文件的路径来创建 Client 实例。

my $properties_file = "/path/to/googleads.properties";

my $api_client = Google::Ads::GoogleAds::Client->new({
  properties_file => $properties_file
});

接下来，使用 GoogleAdsService.SearchStream 方法获取您账号中的广告系列。本指南不涵盖 报告的详细信息。

  sub get_campaigns {
  my ($api_client, $customer_id) = @_;

  # Create a search Google Ads stream request that will retrieve all campaigns.
  my $search_stream_request =
    Google::Ads::GoogleAds::V17::Services::GoogleAdsService::SearchGoogleAdsStreamRequest
    ->new({
      customerId => $customer_id,
      query      =>
        "SELECT campaign.id, campaign.name FROM campaign ORDER BY campaign.id"
    });

  # Get the GoogleAdsService.
  my $google_ads_service = $api_client->GoogleAdsService();

  my $search_stream_handler =
    Google::Ads::GoogleAds::Utils::SearchStreamHandler->new({
      service => $google_ads_service,
      request => $search_stream_request
    });

  # Issue a search request and process the stream response to print the requested
  # field values for the campaign in each row.
  $search_stream_handler->process_contents(
    sub {
      my $google_ads_row = shift;
      printf "Campaign with ID %d and name '%s' was found.\n",
        $google_ads_row->{campaign}{id}, $google_ads_row->{campaign}{name};
    });

  return 1;
}
get_campaigns.pl

REST

首先使用 HTTP 客户端提取 OAuth 2.0 访问令牌。本指南 使用 curl 命令。

curl \
  --data "grant_type=refresh_token" \
  --data "client_id=CLIENT_ID" \
  --data "client_secret=CLIENT_SECRET" \
  --data "refresh_token=REFRESH_TOKEN" \
  https://www.googleapis.com/oauth2/v3/token

接下来，使用 GoogleAdsService.SearchStream 方法来获取您账号中的广告系列。本指南不涵盖 报告的详细信息。

curl -i -X POST https://googleads.googleapis.com/v17/customers/CUSTOMER_ID/googleAds:searchStream \
   -H "Content-Type: application/json" \
   -H "Authorization: Bearer ACCESS_TOKEN" \
   -H "developer-token: DEVELOPER_TOKEN" \
   -H "login-customer-id: LOGIN_CUSTOMER_ID" \
   --data-binary "@query.json"

query.json 的内容如下所示：

{
  "query": "SELECT campaign.id, campaign.name, campaign.network_settings.target_content_network FROM campaign ORDER BY campaign.id"
}
