設定

程式庫會在 System.getProperty("user.home") + "/ads.properties"。您可以覆寫這項設定使用以下程式碼建構 GoogleAdsClient 時，在執行階段使用的路徑和檔案名稱使用下列任一機制：

呼叫 fromPropertiesFile(PATH_TO_CONFIG_FILE)，位置：PATH_TO_CONFIG_FILE 是設定檔的路徑和檔案名稱。
將環境變數 GOOGLE_ADS_CONFIGURATION_FILE_PATH 設為設定檔的路徑和檔案名稱，然後呼叫 fromPropertiesFile()。

設定檔的格式是 Java 資源分為鍵/值組合檔案支援的鍵會因所選的驗證流程

支援的電腦版和網頁應用程式流程金鑰

如果您使用電腦版或 web 應用程式流程，支援的金鑰如下：

# Credential for accessing Google's OAuth servers.
# Provided by console.cloud.google.com.
api.googleads.clientId=INSERT_CLIENT_ID_HERE

# Credential for accessing Google's OAuth servers.
# Provided by console.cloud.google.com.
api.googleads.clientSecret=INSERT_CLIENT_SECRET_HERE

# Renewable OAuth credential associated with 1 or more Google Ads accounts.
api.googleads.refreshToken=INSERT_REFRESH_TOKEN_HERE

# Token which provides access to the Google Ads API in general. It does not
# grant access to any particular ad account (OAuth is used for this purpose).
api.googleads.developerToken=INSERT_DEVELOPER_TOKEN_HERE

# Required for manager accounts only: Specify the login customer ID used to
# authenticate API calls. This will be the customer ID of the authenticated
# manager account. You can also specify this later in code if your application
# uses multiple manager account + OAuth pairs.
#
# api.googleads.loginCustomerId=INSERT_LOGIN_CUSTOMER_ID_HERE

# Only required if explicitly instructed by the service documentation.
# api.googleads.linkedCustomerId=INSERT_LINKED_CUSTOMER_ID_HERE

# Maximum allowed response payload size, in bytes.
# Customize this to allow response sizes for GoogleAdsService.search and
# GoogleAdsService.searchStream API calls to exceed the default limit of 64MB.
# api.googleads.maxInboundMessageBytes=INSERT_MAX_INBOUND_MESSAGE_BYTES_HERE

服務帳戶支援的金鑰

如果您使用服務帳戶支援的鍵如下：

# Path to the service account secrets file in JSON format.
# Provided by console.cloud.google.com.
api.googleads.serviceAccountSecretsPath=INSERT_PATH_TO_JSON_HERE

# Email address of the user to impersonate.
# This should be a user who has access to your Google Ads account and is in the same
# Google Apps Domain as the service account.
api.googleads.serviceAccountUser=INSERT_USER_EMAIL_ADDRESS_HERE

# Token which provides access to the Google Ads API in general. It does not
# grant access to any particular ad account (OAuth is used for this purpose).
api.googleads.developerToken=INSERT_DEVELOPER_TOKEN_HERE

# Required for manager accounts only: Specify the login customer ID used to
# authenticate API calls. This will be the customer ID of the authenticated
# manager account. You can also specify this later in code if your application
# uses multiple manager account + OAuth pairs.
#
# api.googleads.loginCustomerId=INSERT_LOGIN_CUSTOMER_ID_HERE

使用環境變數

該程式庫支援所有 Google Ads API 通用的環境變數用戶端程式庫。下表顯示了環境變數。

設定檔屬性	環境變數
`api.googleads.developerToken`	`GOOGLE_ADS_DEVELOPER_TOKEN`
`api.googleads.clientId`	`GOOGLE_ADS_CLIENT_ID`
`api.googleads.clientSecret`	`GOOGLE_ADS_CLIENT_SECRET`
`api.googleads.refreshToken`	`GOOGLE_ADS_REFRESH_TOKEN`
`api.googleads.serviceAccountSecretsPath`	`GOOGLE_ADS_JSON_KEY_FILE_PATH`
`api.googleads.serviceAccountUser`	`GOOGLE_ADS_IMPERSONATED_EMAIL`
`api.googleads.loginCustomerId`	`GOOGLE_ADS_LOGIN_CUSTOMER_ID`
`api.googleads.linkedCustomerId`	`GOOGLE_ADS_LINKED_CUSTOMER_ID`
`api.googleads.maxInboundMessageBytes`	`GOOGLE_ADS_MAX_INBOUND_MESSAGE_BYTES`

設定適當的環境變數之後，請設定 GoogleAdsClient，方法是在建構工具上呼叫 fromEnvironment()。

GoogleAdsClient googleAdsClient = GoogleAdsClient.newBuilder()
  .fromEnvironment()
  .build();

結合設定方法

GoogleAdsClient 及其建構工具支援合併不同設定舉例來說，您可以使用環境變數執行個體憑證和其他屬性的屬性檔案下列程式碼片段。

GoogleAdsClient googleAdsClient = GoogleAdsClient.newBuilder()
    .fromEnvironment()
    .fromPropertiesFile()
    .build();

在本範例中，用戶端程式庫會使用屬性檔案中的值對透過環境變數和輸入屬性檔案中的一個項目如果是相反行為，只要呼叫 fromEnvironment()前 fromPropertiesFile()。

在執行階段中，您可以使用建構工具的其他設定進一步變更方法，然後再呼叫 build()。
