如何将xmlrpc服务器的日志输出重定向到某个文件

Question

我正在使用SimpleXMLRPCServer模块来创建一个rpc服务器.每当我向服务器发送任何请求时,它都会向我显示连接请求.如何将此输出重定向到某个文件,以便我可以看到稍后向服务器发出的请求.

这是我的服务器脚本

from SimpleXMLRPCServer import SimpleXMLRPCServer
from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler
import logging
import os
import string
from subprocess import Popen,PIPE 
import xmlrpclib
# Set up logging
logging.basicConfig(level=logging.DEBUG, filename = 'RPCServer.log')
class FileOperation():
'''Class to perform file operation on the Remote machine'''
    def __init__(self):
       self.fh = None
       self.os = os            #adding built-in OS module functionality
       self.string = string    #adding built-in String module functionality

# Restrict to a particular path.

class RequestHandler(SimpleXMLRPCRequestHandler):
    rpc_paths = ('/RPC2',)
# Create server
server = SimpleXMLRPCServer(("localhost", 8000), requestHandler = RequestHandler,allow_none = True, logRequests = True)
server.register_introspection_functions()
server.register_instance(FileOperation(),allow_dotted_names = True )


# Run the server's main loop
try:
    print 'Use Control-C to exit'
    server.serve_forever()
except KeyboardInterrupt:
    print 'Exiting'

每当我发送任何请求时,我都会得到这样的o/p -

Use Control-C to exit
127.0.0.1 - - [11/Dec/2013 11:34:29] "POST /RPC2 HTTP/1.1" 200 -

如何将此o/p重定向到某个文件.我在日志配置中设置了文件名,但是o/p没有去那里

邮件被写入sys.stderr.你也可以

1. 重定向stderr,或
2. 在你的子类中SimpleXMLRPCRequestHandler覆盖方法log_message并logging在那里使用,如果你愿意的话.

原始方法BaseHTTPRequestHandler.log_message在模块中BaseHTTPServer,如下所示:

def log_message(self, format, *args):
    """Log an arbitrary message.

    This is used by all other logging functions.  Override
    it if you have specific logging wishes.

    The first argument, FORMAT, is a format string for the
    message to be logged.  If the format string contains
    any % escapes requiring parameters, they should be
    specified as subsequent arguments (it's just like
    printf!).

    The client host and current date/time are prefixed to
    every message.

    """

    sys.stderr.write("%s - - [%s] %s\n" %
                     (self.address_string(),
                      self.log_date_time_string(),
                      format%args))
