造成xmlrpclib.ResponseError: ResponseError()的原因是什么？

Question

我正在尝试使用XML-RPC。

我有一个服务器脚本（用Python写的）：

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'

还有一个客户端脚本：

import xmlrpclib

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

我在本地测试过，这个脚本运行得很好。它的功能就是把客户端脚本输入的数据原封不动地输出，这个是正确的。

但是，当我在远程服务器上尝试时，我遇到了以下错误：

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()

你们觉得这可能是什么原因呢？

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'

错误处理远程服务器数据传输 xml-rpc 客户端脚本服务器脚本 responseerror

造成xmlrpclib.ResponseError: ResponseError()的原因是什么？
