如何使用bigquery_datatransfer Python客戶端創建AdWords BigQuery傳輸和傳輸運行？

Question

我已經能夠成功進行身份驗證，並列出傳輸和傳輸運行。 但是我一直遇到由於傳輸配置不正確而無法創建傳輸的問題。

這是我嘗試過的傳輸配置：

transferConfig = {
    'data_refresh_window_days': 1,
    'data_source_id': "adwords",
    'destination_dataset_id': "AdwordsMCC",
    'disabled': False,
    'display_name': "TestR",
    'name': "TestR",
    'schedule': "every day 07:00",
    'params': {
        "customer_id": "999999999" -- Changed Number
    }
}

response = client.create_transfer_config(parent, transferConfig)
print(response)

這是我得到的錯誤：

Traceback (most recent call last):
File "./create_transfer.py", line 84, in <module>
    main()
File "./create_transfer.py", line 61, in main
    response = client.create_transfer_config(parent, transferConfig)

    authorization_code=authorization_code)

通過將params定義為google.protobuf.struct_pb2.Struct類，我設法通過API設置了數據傳輸。

嘗試添加以下內容是否適合您：

from google.protobuf.struct_pb2 import Struct

params = Struct()
params["customer_id"] = "999999999"

然后將您的transferConfig更改為：

transferConfig = {
    'data_refresh_window_days': 1,
    'data_source_id': "adwords",
    'destination_dataset_id': "AdwordsMCC",
    'disabled': False,
    'display_name': "TestR",
    'name': "TestR",
    'schedule': "every day 07:00",
    'params': params
    }
}
