客户端库

我们的客户端库提供了 Google Ads API 功能的高级视图和基本构建块，以便您更轻松地快速开发应用。如果您刚开始接触该 API，我们建议您先从一个开始。

支持的 API 版本

下表显示了哪些客户端库适用于哪些 API 版本。

配置

每个 Ads API 客户端库都提供不同的配置设置 这些加载方法可用于自定义其行为。

以下是适用于所有客户端库的环境变量，可加载以设置配置设置：

• 客户端库
  • GOOGLE_ADS_CONFIGURATION_FILE_PATH：配置文件的路径。
• OAuth2
  • 应用模式
    • GOOGLE_ADS_CLIENT_ID：将此值设置为您的 OAuth2 客户端 ID。
    • GOOGLE_ADS_CLIENT_SECRET：将此值设置为您的 OAuth2 客户端密钥。
    • GOOGLE_ADS_REFRESH_TOKEN：如果您想重复使用 OAuth2 令牌，请将此值设置为预生成的 OAuth2 刷新令牌。此设置是可选的。
  • 服务账号模式
    • GOOGLE_ADS_JSON_KEY_FILE_PATH：将此值设置为 OAuth2 JSON 配置文件路径。
    • GOOGLE_ADS_IMPERSONATED_EMAIL：将此值设置为您要模拟的账号的电子邮件地址。
• Google Ads API
  • GOOGLE_ADS_DEVELOPER_TOKEN：将此值设置为您的开发者令牌。
  • GOOGLE_ADS_LOGIN_CUSTOMER_ID：这是在请求中使用的授权客户的客户 ID，它不带连字符 (-)。
  • GOOGLE_ADS_LINKED_CUSTOMER_ID：只有更新 实体资源（通过 Google Ads 界面（Google Ads API 中的 AccountLink 资源）。将此值设置为更新指定客户 ID 的资源的数据提供商的客户 ID。设置时应不带连字符 (-)。如需详细了解关联的账号，请访问帮助中心。

环境变量通常在 bash 配置文件（例如位于 $HOME 目录中的 .bashrc 或 .bash_profile 文件）中定义。他们 也可以使用命令行进行定义

以下是使用终端通过 .bashrc 文件定义环境变量的几个基本步骤：

# Append the line "export GOOGLE_ADS_CLIENT_ID=1234567890" to
# the bottom of your .bashrc file.
echo "export GOOGLE_ADS_CLIENT_ID=1234567890" >> ~/.bashrc

# Update your bash environment to use the most recently updated
# version of your .bashrc file.
src ~/.bashrc

您也可以直接通过以下命令在终端实例中设置环境变量： 请在命令行中运行以下命令：

export GOOGLE_ADS_CLIENT_ID=1234567890

另一种方法是在调用使用环境变量的命令时设置环境变量：

GOOGLE_ADS_CLIENT_ID=1234567890 php /path/to/script/that/uses/envvar.php

搜索分页

GoogleAdsService.Search 通常用于显示结果页面的交互式应用。页面大小固定为每页 1 万条结果。

我们的客户端库会自动实现 分页，以便您可以 依序下载和一次性处理所有请求，例如：

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
      

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}");
