python - 使用 Python 从 Google 文档中删除资源

Question

我正在尝试使用此功能删除 Google 文档中的电子表格:

def f_DeleteResource(xls_name):
  """Delete a resource"""
  client=Auth()
  for e1 in client.GetResources().entry:
    e2 = client.GetResource(e1)
    if xls_name==e2.title.text:
      client.DeleteResource(e2.resource_id.text,True)

当我更改 client.DeleteResource(p1,p2) 的第一个参数时，我得到了不同的错误:

client.DeleteResource(e2.resource_id.text,True):

Traceback (most recent call last):
File "C:\xmp\D6GDocsDeleteUpload.py", line 164, in <module> main()
File "C:\xmp\D6GDocsDeleteUpload.py", line 157, in main f_DeleteResource(sys.argv[2])
File "C:\xmp\D6GDocsDeleteUpload.py", line 144, in f_DeleteResource client.DeleteResource(e2.resource_id.text,True)
File "C:\Python27\lib\site-packages\gdata\docs\client.py", line 540, in delete_resource uri = entry.GetEditLink().href
AttributeError: 'str' object has no attribute 'GetEditLink'

client.DeleteResource(e2,True):

谁能帮帮我？

这似乎是 Google API Python 库中的错误。我检查了 gdata-2.0.16 并注意到 DeleteResource() 函数仅使用资源的 URL(gdata/docs/client.py 第 540-543 行)，但后来检查 hasattr(entry_or_uri, 'etag')(gdata/client.py 行 737-741)，当然字符串值 (uri) 没有 etag 属性。

您可以使用 force 关键字参数来解决它:

import gdata.docs.data
import gdata.docs.client

client = gdata.docs.client.DocsClient()
client.ClientLogin('xxxxxx@gmail.com', 'xxxxxx', 'XxX')

for doc in client.GetAllResources():
    if doc.title.text == 'qpqpqpqpqpqp':
        client.DeleteResource(doc, force=True)
        break

如果您愿意，您可以向库维护者报告错误(如果尚未报告)。
