Question

我正在尝试使用“ get”获取文件的URL链接。 Web版本的API返回所有属性或“键”。但是，当我尝试通过Python代码访问它时，它仅返回有限数量的键，如“ mimetype”之类的项目，但没有URL信息。我认为已包含适当的“范围”，并且授权文件“ token.json”是当前的，但是当对目标文件进行查询时，代码将引发“ keyError”。下面是运行代码时的响应。它找到了文件，但是仅报告了有限数量的密钥，如下所示：

{u'mimeType': u'image/gif', u'kind': u'drive#file', u'id': u'0B3rj986AqarFMHBWNng1T043WkE', u'name': u'sketchImage.gif'}

Traceback (most recent call last):
  File "C:/Python27/stackQuestion.py", line 35, in <module>
    main()
  File "C:/Python27/stackQuestion.py", line 33, in main
    print(myFile['alternateLink'])
KeyError: 'alternateLink'
