AttributeError:条目实例没有属性''uuLen'

Question

我对python相当陌生，我一直在尝试使用Tkinter和requests来创建一个可以登录到我的web应用程序的简单程序。我得到了以下错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py", line 1410, in __call__
    return self.func(*args)
  File "test.py", line 35, in login
    c.post('http://fruro.com/login.php', data=self.payload)
  File "/Users/Peter/Desktop/fruroPy/fruro/lib/python2.7/site-packages/requests/sessions.py", line 399, in post
    return self.request('POST', url, data=data, **kwargs)
  File "/Users/Peter/Desktop/fruroPy/fruro/lib/python2.7/site-packages/requests/sessions.py", line 343, in request
    prep = req.prepare()
  File "/Users/Peter/Desktop/fruroPy/fruro/lib/python2.7/site-packages/requests/models.py", line 222, in prepare
    p.prepare_body(self.data, self.files)
  File "/Users/Peter/Desktop/fruroPy/fruro/lib/python2.7/site-packages/requests/models.py", line 375, in prepare_body
    body = self._encode_params(data)
  File "/Users/Peter/Desktop/fruroPy/fruro/lib/python2.7/site-packages/requests/models.py", line 81, in _encode_params
    return urlencode(result, doseq=True)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib.py", line 1311, in urlencode
    len(v)
AttributeError: Entry instance has no attribute '__len__'

几个小时来，我一直在想到底是什么出了问题，但我不知道我做错了什么。在

以下是我正在使用的代码：

问题出在这条线上

c.post('http://fruro.com/login.php', data=self.payload)

这是因为作为data传入的dict参数的值是对Entry小部件的引用，而不是这些小部件的内容。因此，当Requests试图获得len时，您会得到一个错误，因为Entry没有实现{}（反正不是您想要的）。要修复它，请将self.payload更改为类似于
