用戶端程式庫

我們的用戶端程式庫提供 Google Ads API 功能的高階檢視畫面和基本構成元素，方便您快速開發應用程式。如果您剛開始使用 API，建議您從這個版本著手。

支援的 API 版本

下表列出哪些用戶端程式庫可與哪些 API 版本搭配使用。

設定

每個 Ads API 用戶端程式庫都提供不同的配置設定和載入方法，可讓您用來自訂行為。

以下是所有用戶端程式庫通用的環境變數，您可以載入這些變數以調整設定：

• 用戶端程式庫
  • GOOGLE_ADS_CONFIGURATION_FILE_PATH：設定檔路徑。
• OAuth2
  • 應用程式模式
    • GOOGLE_ADS_CLIENT_ID：將這個值設為 OAuth2 用戶端 ID。
    • GOOGLE_ADS_CLIENT_SECRET：將這個值設為 OAuth2 用戶端密鑰。
    • GOOGLE_ADS_REFRESH_TOKEN：如果想重複使用 OAuth2 權杖，請將這個值設為預先產生的 OAuth2 更新權杖。這是選用設定。
  • 服務帳戶模式
    • GOOGLE_ADS_JSON_KEY_FILE_PATH：將這個值設為 OAuth2 JSON 設定檔路徑。
    • GOOGLE_ADS_IMPERSONATED_EMAIL：將這個值設為要模擬的帳戶電子郵件地址。
• Google Ads API
  • GOOGLE_ADS_DEVELOPER_TOKEN：將此設為開發人員權杖。
  • GOOGLE_ADS_LOGIN_CUSTOMER_ID：這是在要求中使用的授權客戶 ID，不含連字號 (-)。
  • GOOGLE_ADS_LINKED_CUSTOMER_ID：只有在 Google Ads UI 的「已連結帳戶」透過「已連結帳戶」授予權限時 (Google Ads API 中的 AccountLink 資源)，才需要此標頭。將這個值設為資料供應商的客戶 ID，該資料供應商會更新指定客戶 ID 的資源。應設定不含連字號 (-)。如要進一步瞭解已連結帳戶，請前往說明中心。

環境變數通常會在 bash 設定檔中定義，例如位於 $HOME 目錄的 .bashrc 或 .bash_profile 檔案。您也可以使用指令列來定義。

以下列舉幾個透過終端機使用 .bashrc 檔案定義環境變數的基本步驟：

# 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

您也可以直接透過指令列在終端機執行個體中設定環境變數：

export GOOGLE_ADS_CLIENT_ID=1234567890

另一個替代方法是在呼叫使用這些變數的指令時設定環境變數：

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

搜尋分頁

GoogleAdsService.Search 通常用於顯示結果頁面的互動式應用程式。

我們的用戶端程式庫會在您疊代結果時自動實作分頁，方便您依序下載並一次處理所有結果，例如：

• 一次最佳化儲存多少結果。
• 下載並處理特定順序的結果頁面。

方法是儲存頁面符記 (而非結果)，這會增加程式碼的複雜度。
