Python Urllib2-Django-管道断裂

我是Django的新手，在将数据发布到Django Web应用程序时遇到一些问题

在django方面，我有一个表单（由couchdb-couchdbkit-django-ext支持）。 在客户端，我使用urllib2批量发布数据（通过数据列表逐个发布）

在一条记录（一次post传递）之后，它得到下面的消息，再次运行下一行传递，我再次得到此消息：

       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()

我必须声明我正在开发嵌入式django开发web服务器

这是测试的输出：

有人知道怎么修理吗

有时我发现使用development server（如您的日志）时出现奇怪的错误和快速连接重置。如果你的应用程序是关于http、REST和webservices的，你应该使用Apache或Gunicorn，这样你在开发时会感觉到一个更真实的环境。

问题似乎出在你的服务器代码上，而不是客户端。事实上，客户端只是说服务器返回了一个错误代码。您可能希望尝试/捕获服务器代码以查看该端的异常。或者使用单元测试，您可以使用测试客户端（

self.client

，在测试用例中）执行与使用urllib类似的操作。我添加了服务器日志。我将编写一个测试。这些stacktraces看起来像是一个客户在阅读发送给他的内容之前离开的。如果未提升默认日志级别，则应仅在控制台中看到GET/objects/create/500。您应该在django视图中添加一个try/catch，例如import traceback traceback.print_exc（）。或者尝试单元测试：）我同时添加了测试输出，我将添加您建议的try/catch块……这是否意味着嵌入式服务器不稳定？Cherrypy对于开发来说已经足够稳定了，并且正是为了实现这一点。坚持到错误解决为止。Django不使用cherrypy作为开发服务器。@patoch，假设它没有涵盖所有场景。如果您的架构足够大，您应该在更类似于生产环境的环境中进行早期测试，并且不要忘记在应用程序的编码会话中使用DEBUG=False运行一次。
