Python Dropbox核心 API：获取 dropbox.rest.ErrorResponse：[400] 'invalid_grant

Question

我正在一步一步地按照Dropbox的Python文档进行操作，但在这个步骤遇到了意外的错误，卡住了。

elif args.sync:
    print("syncing")
    import dropbox
    flow = dropbox.client.DropboxOAuth2FlowNoRedirect(dropbox_appKey, dropbox_appSecret)
    authorize_url = flow.start()
    print("1. Go to: ", authorize_url)
    print("2. Click \"Allow\" (you might have to log in first)")
    print("3. Copy the authorization code.")
    code = input("Enter the authorization code here: ").strip
    access_token, user_id = flow.finish(code)
    client = dropbox.client.DropboxClient(access_token)
    print("linked account: ", client.account_info())

错误追踪信息：

Traceback (most recent call last):
  File "./eldiario", line 92, in <module>
    access_token, user_id = flow.finish(code)
  File "/usr/local/lib/python3.4/site-packages/dropbox/client.py", line 1233, in finish
    return self._finish(code, None)
  File "/usr/local/lib/python3.4/site-packages/dropbox/client.py", line 1101, in _finish
    response = self.rest_client.POST(url, params=params)
  File "/usr/local/lib/python3.4/site-packages/dropbox/rest.py", line 316, in POST
    return cls.IMPL.POST(*n, **kw)
  File "/usr/local/lib/python3.4/site-packages/dropbox/rest.py", line 254, in POST
    post_params=params, headers=headers, raw_response=raw_response)
  File "/usr/local/lib/python3.4/site-packages/dropbox/rest.py", line 227, in request
    raise ErrorResponse(r, r.read())
dropbox.rest.ErrorResponse: [400] 'invalid_grant'

有没有人知道这是什么问题呢？

看起来你在 strip 后面少了几个括号。

应该像这样：

code = input("Enter the authorization code here: ").strip()
