我在登录方面遇到了麻烦.我正在运行CherryPy 3.2并且我一直在阅读文档 here,但是没有找到任何关于如何为输出配置本地日志文件以及如何写入它的示例.

Raspberry.py：

import socket
import sys
import cherrypy

app_roots = {
                # Sean's laptop dev environment.
                "mylaptop": "/home/src/local-mydomain.com/py",# Hosted dev environment.  
                "mydomain.com" : "/home/dev/src/py"
            }


hostname = socket.gethostname()
CherryPyLog = cherrypy.tree.mount().log

if hostname not in app_roots:
    CherryPyLog("The following hostname does not have an app_root entry in raspberry.py.  Exiting early.")
    sys.exit()

sys.stdout = sys.stderr
sys.path.append(app_roots[hostname])

import os
os.chdir(app_root)

# Setup for raspberry application logging.
import datetime
today = datetime.datetime.today()
log.access_file = "{0}/{1}.raspberry.access.log".format(app_roots[hostname],today.strftime("%Y%m%d-%H%M"))
log.error_file = "{0}/{1}.raspberry.error.log".format(app_roots[hostname],today.strftime("%Y%m%d-%H%M"))

#Testing logger
log("{0} -- Logger configured".format(today.strftime("%Y%m%d-%H%M%S")))

import atexit
cherrypy.config.update({'environment': 'embedded'})

if cherrypy.__version__.startswith('3.0') and cherrypy.engine.state == 0:
    cherrypy.engine.start(blocking = False)
    atexit.register(cherrypy.engine.stop)

from web.controllers.root import RaspberryRequestHandler

application = cherrypy.Application(RaspberryRequestHandler(),script_name = None,config = None)

更新：这是我最终使用的代码块.

app_roots = {
                # Sean's laptop dev environment.
                "mylaptop": "/home/src/local-plottools.com/py",# Hosted dev environment.  
                "myDomain" : "/home/dev/src/py"
            }

                            })
