进行 API 调用

本指南需要在前面的步骤中配置的几个前提条件设置。如果您尚未阅读简介，请先阅读。

进行 API 调用

选择您偏好的客户端，了解如何发出 API 调用：

Java

客户端库工件会发布到 Maven 中央制品库。将客户端库作为依赖项添加到您的项目中，如下所示：

Maven 依赖项为：

<dependency>
  <groupId>com.google.api-ads</groupId>
  <artifactId>google-ads</artifactId>
  <version>35.0.0</version>
</dependency>

Gradle 依赖项为：

implementation 'com.google.api-ads:google-ads:35.0.0'

api.googleads.serviceAccountSecretsPath=JSON_KEY_FILE_PATH
api.googleads.developerToken=INSERT_DEVELOPER_TOKEN_HERE
api.googleads.loginCustomerId=INSERT_LOGIN_CUSTOMER_ID_HERE

按照如下所示创建一个 GoogleAdsClient 对象：

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 方法生成广告系列报告，以检索您账号中的广告系列。本指南不介绍报告的详细信息。

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，将 nuget 引用添加到 Google.Ads.GoogleAds 软件包。

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

使用相关设置创建 GoogleAdsConfig 对象，并使用该对象创建 GoogleAdsClient 对象。

GoogleAdsConfig config = new GoogleAdsConfig()
{
    DeveloperToken = "******",
    OAuth2Mode = OAuth2Flow.SERVICE_ACCOUNT,
    OAuth2SecretsJsonPath = "PATH_TO_CREDENTIALS_JSON",
    LoginCustomerId = ******
};
GoogleAdsClient client = new GoogleAdsClient(config);

接下来，使用 GoogleAdsService.SearchStream 方法生成广告系列报告，以检索您账号中的广告系列。本指南不介绍报告的详细信息。

public void Run(GoogleAdsClient client, long customerId)
{
    // Get the GoogleAdsService.
    GoogleAdsServiceClient googleAdsService = client.GetService(
        Services.V18.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。切换到项目的根目录，然后运行以下命令，将该库及其所有依赖项安装到项目根目录的 vendor/ 目录中。

composer require googleads/google-ads-php:25.0.0

复制 GitHub 代码库中的 google_ads_php.ini 文件，并将其修改为包含您的凭据。

[GOOGLE_ADS]
developerToken = "INSERT_DEVELOPER_TOKEN_HERE"
loginCustomerId = "INSERT_LOGIN_CUSTOMER_ID_HERE"

[OAUTH2]
jsonKeyFilePath = "INSERT_ABSOLUTE_PATH_TO_OAUTH2_JSON_KEY_FILE_HERE"
scopes = "https://www.googleapis.com/auth/adwords"

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 方法生成广告系列报告，以检索您账号中的广告系列。本指南不介绍报告的详细信息。

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

该客户端库分发在 PyPI 上，可使用 pip 命令安装，如下所示：

python -m pip install google-ads==21.3.0

复制 GitHub 代码库中的 google-ads.yaml 文件，并对其进行修改以添加您的凭据。

developer_token: INSERT_DEVELOPER_TOKEN_HERE
login_customer_id: INSERT_LOGIN_CUSTOMER_ID_HERE
json_key_file_path: JSON_KEY_FILE_PATH_HERE

通过调用 GoogleAdsClient.load_from_storage 方法创建 GoogleAdsClient 实例。调用该方法时，将 google-ads.yaml 的路径作为字符串传递给该方法：

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

接下来，使用 GoogleAdsService.SearchStream 方法生成广告系列报告，以检索您账号中的广告系列。本指南不介绍报告的详细信息。

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。建议使用 Bundler 进行安装。将以下代码行添加到 Gemfile 中：

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

然后运行以下命令：

bundle install

复制 GitHub 代码库中的 google_ads_config.rb 文件，并将其修改为包含您的凭据。

Google::Ads::GoogleAds::Config.new do |c|
  c.developer_token = 'INSERT_DEVELOPER_TOKEN_HERE'
  c.login_customer_id = 'INSERT_LOGIN_CUSTOMER_ID_HERE'
  c.keyfile = 'JSON_KEY_FILE_PATH'
end

通过传递此文件的存储路径来创建 GoogleAdsClient 实例。

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

接下来，使用 GoogleAdsService.SearchStream 方法生成广告系列报告，以检索您账号中的广告系列。本指南不介绍报告的详细信息。

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

该库在 CPAN 上分发。首先，在您选择的目录中克隆 google-ads-perl 代码库。

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

切换到 google-ads-perl 目录，然后在命令提示符中运行以下命令，以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 GitHub 代码库中的 googleads.properties 文件，并对其进行修改以添加您的凭据。

jsonKeyFilePath=JSON_KEY_FILE_PATH
developerToken=INSERT_DEVELOPER_TOKEN_HERE
loginCustomerId=INSERT_LOGIN_CUSTOMER_ID_HERE

通过传递此文件的存储路径来创建 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 方法生成广告系列报告，以检索您账号中的广告系列。本指南不介绍报告的详细信息。

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::V18::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。

gcloud auth \
  print-access-token \
  --scopes='https://www.googleapis.com/auth/adwords'

接下来，使用 GoogleAdsService.SearchStream 方法生成广告系列报告，以检索您账号中的广告系列。本指南不介绍报告的详细信息。

curl -i -X POST https://googleads.googleapis.com/v18/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"
}
