python - 什么可能导致 xmlrpclib.ResponseError : ResponseError()?

Question

我正在试验 XML-RPC。

我有以下服务器脚本(Python):

from SimpleXMLRPCServer import SimpleXMLRPCServer

server = SimpleXMLRPCServer(('localhost', 9000))

def return_input(someinput):
return someinput

server.register_function(return_input)

try:
     print 'ctrl-c to stop server'
     server.serve_forever()
except KeyboardInterrupt:
     print 'stopping'

和以下客户端脚本:

import xmlrpclib

server = xmlrpclib.ServerProxy('http://www.example.com/pathto/xmlrpcTester2.py')
print server.return_input('some input')

我已经在本地测试过了，效果很好。它所做的一切都是从客户端脚本中吐出输入，这是正确的。

但是，当我尝试在远程服务器上执行此操作时，出现以下错误:

Traceback (most recent call last):
  File "client.py", line 4, in <module>
    print server.return_input('some input')
  File     "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line     1199, in __call__
    return self.__send(self.__name, args)
  File     "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line     1489, in __request
    verbose=self.__verbose
  File     "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line     1253, in request
return self._parse_response(h.getfile(), sock)
 File     "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line     1392, in _parse_response
return u.close()
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xmlrpclib.py", line 836, in close
raise ResponseError()
xmlrpclib.ResponseError: ResponseError()

有什么想法会导致这种情况吗？

更新:

当 verbose=True 时:

send: 'POST /pythonScripts/xmlrpcTester2.py HTTP/1.0\r\nHost:         www.example.com\r\nUser-Agent: xmlrpclib.py/1.0.1 (by www.pythonware.com)\r\nContent-    Type: text/xml\r\nContent-Length: 166\r\n\r\n'

看起来远程机器上的那个端口上正在运行其他东西。并发回一个意想不到的答案。

我会检查服务器是否正确启动。然后检查防火墙设置中是否有任何可能影响事情的东西。

您还可以在客户端中打开详细标志，看看是否能说明问题。

编辑:

所以详细的输出清楚地表明了问题:您没有运行服务器，您是通过普通网络服务器共享它!

您需要在远程机器上运行服务器。
