Urllib2 - Django - 管道断裂

Question

我刚接触Django，正在尝试把数据发送到一个Django网页应用，但遇到了一些问题。

在Django这边，我有一个表单（使用的是couchdb - couchdbkit这个Django扩展）。在客户端，我用urllib2来批量发送数据（也就是逐个处理一个数据列表）。

data = urllib.urlencode(param)
req = urllib2.Request(OBJECT_SERVICE_URL + '/objects/create/', data)
req.add_header('Content-type', 'application/x-www-form-urlencoded')
res = urllib2.urlopen(req)
res.close()

在发送一个记录（一个数据发送成功）后，出现了下面的错误信息，接着再运行下一行又能成功，但又会出现同样的错误：

       res = urllib2.urlopen(req)
  File "/usr/lib/python2.6/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.6/urllib2.py", line 397, in open
    response = meth(req, response)
  File "/usr/lib/python2.6/urllib2.py", line 510, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib/python2.6/urllib2.py", line 435, in error
    return self._call_chain(*args)
  File "/usr/lib/python2.6/urllib2.py", line 369, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.6/urllib2.py", line 518, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
  urllib2.HTTPError: HTTP Error 500: INTERNAL SERVER ERROR

服务器说：

    Traceback (most recent call last):
  File "/usr/local/lib/python2.6/dist-packages/django/core/servers/basehttp.py", line 284, in run
    self.finish_response()

我得说明一下，我是在使用内置的Django开发服务器进行开发……

这是测试的输出结果：

有没有人知道该怎么解决这个问题？
