Question

我发现配方会在http://code.activestate.com/recipes/496700-logging-simplexmlrpcserver/

处记录XML-RPC服务器的活动

我遇到的问题是我想重用LoggingSimpleRPCRequestHandler（即导入它），但我不知道如何正确设置'logger'变量。这个想法是

这有效（LoggedWork.py）：

from SimpleXMLRPCServer import SimpleXMLRPCServer, SimpleXMLRPCRequestHandler
from SocketServer import ThreadingMixIn

import os, sys
import logging

class RemoteObject:    
    def return10(self):
        return 10

class LoggingSimpleXMLRPCRequestHandler(SimpleXMLRPCRequestHandler): 
    """Overides the default SimpleXMLRPCRequestHander to support logging.  Logs
    client IP and the XML request and response.
    """    

    def do_POST(self):
        clientIP, port = self.client_address
    # Log client IP and Port

        logger.info('Client IP: %s - Port: %s' % (clientIP, port))
        try:
            # get arguments
            data = self.rfile.read(int(self.headers["content-length"]))
            # Log client request
        logger.info('Client request: \n%s\n' % data)

            response = self.server._marshaled_dispatch(
                    data, getattr(self, '_dispatch', None)
                )
        # Log server response
            logger.info('Server response: \n%s\n' % response)

    except: # This should only happen if the module is buggy
            # internal error, report as HTTP server error
            self.send_response(500)
            self.end_headers()
        else:
            # got a valid XML RPC response
            self.send_response(200)
            self.send_header("Content-type", "text/xml")
            self.send_header("Content-length", str(len(response)))
            self.end_headers()
            self.wfile.write(response)

            # shut down the connection
            self.wfile.flush()
            self.connection.shutdown(1)

class ThreadingServer(ThreadingMixIn, SimpleXMLRPCServer):
    pass

if __name__ == "__main__":

    logger = logging.getLogger('Log')
    hdlr = logging.FileHandler('Log.log')
    formatter = logging.Formatter("%(asctime)s  %(levelname)s  %(message)s")
    hdlr.setFormatter(formatter)
    logger.addHandler(hdlr)
    logger.setLevel(logging.INFO)


    serveraddr = ('', 10001)
    srvr       = ThreadingServer(serveraddr, LoggingSimpleXMLRPCRequestHandler)    
    srvr.register_instance(RemoteObject())
    srvr.register_introspection_functions()

    srvr.serve_forever()

而这不是（LoggedBroken.py）：

from SimpleXMLRPCServer import SimpleXMLRPCServer, SimpleXMLRPCRequestHandler
from SocketServer import ThreadingMixIn
from  LoggingSimpleXMLRPCRequestHandler import  LoggingSimpleXMLRPCRequestHandler
import os, sys
import logging

class RemoteObject:    
    def return10(self):
        return 10

class ThreadingServer(ThreadingMixIn, SimpleXMLRPCServer):
    pass

if __name__ == "__main__":

    logger = logging.getLogger('Log')
    hdlr = logging.FileHandler('Log.log')
    formatter = logging.Formatter("%(asctime)s  %(levelname)s  %(message)s")
    hdlr.setFormatter(formatter)
    logger.addHandler(hdlr)
    logger.setLevel(logging.INFO)


    serveraddr = ('', 10001)
    srvr       = ThreadingServer(serveraddr, LoggingSimpleXMLRPCRequestHandler)    
    srvr.register_instance(RemoteObject())
    srvr.register_introspection_functions()

    srvr.serve_forever()

如果有更好的方法，请告知。谢谢。

好的，我没有正确读你的代码。现在我看到，在这种结构中，我不可能做我提出的建议。我在这里要做的是在模块级别准备自定义记录器，并在LoggingSimpleXMLRPCRequestHandler中按名称检索它。

您正在“main”中执行此操作：配置名为“Log”的记录器。然后在LoggingSimpleXMLRPCRequestHandler中检索该记录器：

class LoggingSimpleXMLRPCRequestHandler(SimpleXMLRequestHandler):
    def __init__(self):
        self.logger = logging.getLogger('Log')

并且在LoggingSimpleXMLRPCRequestHandler方法中使用self.logger代替logger。
