Python 如何在xmlrpc服务器而不是客户端上查看回溯？

我有简单的xmlrpc服务器代码：

from SimpleXMLRPCServer import SimpleXMLRPCServer

port = 9999

def func():
    print 'Hi!'
    print x # error!
    print 'Bye!'

if __name__ == '__main__':
    server = SimpleXMLRPCServer(("localhost", port))
    print "Listening on port %s..." % port
    server.register_function(func)
    server.serve_forever()

示例会话

客户：

问题是我是否也可以在服务器上获取此跟踪。我需要知道处理查询时是否出现问题。我没有使用用Python编写的客户端，因此很难像上面那样进行回溯。

您可以这样做：

from SimpleXMLRPCServer import SimpleXMLRPCServer, SimpleXMLRPCRequestHandler

port = 9999

def func():
    print 'Hi!'
    print x # error!
    print 'Bye!'

class Handler(SimpleXMLRPCRequestHandler):
     def _dispatch(self, method, params):
         try: 
             return self.server.funcs[method](*params)
         except:
             import traceback
             traceback.print_exc()
             raise


if __name__ == '__main__':
    server = SimpleXMLRPCServer(("localhost", port), Handler)
    server.register_function(func)
    print "Listening on port %s..." % port
    server.serve_forever()

回溯服务器端：

Listening on port 9999...
Hi!
Traceback (most recent call last):
  File "xml.py", line 13, in _dispatch
    value = self.server.funcs[method](*params)
  File "xml.py", line 7, in func
    print x # error!
NameError: global name 'x' is not defined
localhost - - [11/Jan/2011 17:13:16] "POST /RPC2 HTTP/1.0" 200

你的问题真让人困惑。您说您没有在python中使用客户机，但您的客户机是python代码。是的，但这只是一个示例。作为客户端，我正在使用一些基于xmlrpc-c库的dll。而且我真的不想更改这个dll的代码…这将节省我几天的时间。谢谢。应该显式使用requestHandler关键字，

SimpleXMLRPCServer（（“localhost”，port），requestHandler=Handler）

from SimpleXMLRPCServer import SimpleXMLRPCServer, SimpleXMLRPCRequestHandler

port = 9999

def func():
    print 'Hi!'
    print x # error!
    print 'Bye!'

class Handler(SimpleXMLRPCRequestHandler):
     def _dispatch(self, method, params):
         try: 
             return self.server.funcs[method](*params)
         except:
             import traceback
             traceback.print_exc()
             raise


if __name__ == '__main__':
    server = SimpleXMLRPCServer(("localhost", port), Handler)
    server.register_function(func)
    print "Listening on port %s..." % port
    server.serve_forever()

Listening on port 9999...
