python Tkinter和urllib2 脚本问题：报错

周末时写的一个可以自动提交BUG的脚本，主要是从excel中读取信息，然后自动保存到服务器上。最初是纯脚本，测试过执行没问题，功能也实现了。后来经理要求改成界面的，昨天看了下Tkinter，拼装了界面，也传了参数，但是就是提交不过去，一直报错：

Traceback (most recent call last):
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 1410, in __call__
    return self.func(*args)

    self.headerBody(testUrl,list_2,sendheaders)

    returnedResult=urllib2.urlopen(returnedReq).read()

    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
HTTPError: HTTP Error 404: Not Found

下面我把脚本贴出来，大家帮忙看看是什么问题吧，多谢了。我是做测试的，之前自学过python的语法，也看过Django，不过都没实战。大家见谅。
