http请求，服务器主动断开连接错误，我写的代码有问题吗

dreameng7

cn =httplib.HTTPConnection('10.100.1.13:8000')

data = urllib.urlencode({'user_name':'测试'})

cn.request('POST', '/test/',data)

result = cn.getresponse()

resultContent = result.read()

result.close()

cn.close()

这段代码有什么问题，为什么执行第二次，服务器就会报

error: [Errno 10054]
