Question

我正在尝试使用Google的python API客户端库将a public file from Google Drive导出到本地驱动器。

我正在使用this script，这是this tutorial的改编示例。我已经验证了我的凭据是否有效，并且整天都在使用create和update方法，没有任何问题。

当我从命令行运行python api_demo.py时，我得到了预期的结果，并将PDF存储到我的本地驱动器中：

aaronpolhamus$ python api_demo.py
  Uploaded "hello.txt" (text/plain)
  Uploaded "hello.txt" (application/vnd.google-apps.document)
  fileId: P110vUov9J9rg2b1XoHMZ3Ssb4Z-FUUPKNQckuyxn_gmo
  mimeType: application/pdf
  Downloaded "hello.pdf" (application/pdf)

然而，当我进入python shell以交互方式工作时，我只是无法让它运行。这是它的外观：

In [1]: DRIVE.files().export(fileId='P110vUov9J9rg2b1XoHMZ3Ssb4Z-FUUPKNQckuyxn_gmo', mimeType='application/pdf').execute()

/Users/aaronpolhamus/anaconda/envs/credijusto/lib/python3.6/site-packages/oauth2client/_helpers.py in positional_wrapper(*args, **kwargs)
131                 elif positional_parameters_enforcement == POSITIONAL_WARNING:
132                     logger.warning(message)
--> 133             return wrapped(*args, **kwargs)
134         return positional_wrapper
135 

/Users/aaronpolhamus/anaconda/envs/credijusto/lib/python3.6/site-packages/googleapiclient/http.py in execute(self, http, num_retries)
838       callback(resp)
839     if resp.status >= 300:
--> 840       raise HttpError(resp, content, uri=self.uri)
841     return self.postproc(resp, content)
842 

HttpError: <HttpError 404 when requesting https://www.googleapis.com/drive/v3/files/P110vUov9J9rg2b1XoHMZ3Ssb4Z-FUUPKNQckuyxn_gmo/export?mimeType=application%2Fpdf returned "File not found: P110vUov9J9rg2b1XoHMZ3Ssb4Z-FUUPKNQckuyxn_gmo.">

现在，如果您转到该链接，fileId实际上并没有领先P1。我尝试将前两个字符砍掉，然后出现500错误：

In [2]: DRIVE.files().export(fileId='10vUov9J9rg2b1XoHMZ3Ssb4Z-FUUPKNQckuyxn_gmo', mimeType='application/pdf').execute()

HttpError                                 Traceback (most recent call last)

命令行和交互式案例之间的区别是令人费解的，因为我可以产生不同的错误，但却没有更接近实际弄清楚发生了什么。我正在进行完全相同的操作，粘贴与终端中打印的值相同的值。

代码和示例数据都是公开的。有帮助吗？
