Question

我遇到了日志记录问题。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"
            }

import socket
hostname = socket.gethostname()

import cherrypy
import sys
if hostname not in app_roots:
    cherrypy.log("The hostname {0} does not have an app_root entry in {1}.  Exiting early.".format(hostname,__file__))
    sys.exit()

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

import os
os.chdir(app_roots[hostname])

from web.controllers.root import RaspberryRequestHandler

cherrypy.config.update({
    'log.access_file': "{0}/cherrypy-access.log".format(app_roots[hostname]),
    'log.error_file': "{0}/cherrypy.log".format(app_roots[hostname]),
    "server.thread_pool" : 10
})

# special case, handling debug sessions when quickstart is needed.
if __name__ == "__main__":

    cherrypy.config.update({
                                'log.screen': True, 
                                "server.socket_port": 8000
                            })
    cherrypy.quickstart(RaspberryRequestHandler())
    sys.exit()

# This configuration is needed for running under mod_wsgi.  See here:  http://tools.cherrypy.org/wiki/ModWSGI    
cherrypy.config.update({'environment': 'embedded'})

applicationLogName = "{0}/raspberry.log".format(app_roots[hostname])

from logging import handlers
applicationLogFileHandler = handlers.RotatingFileHandler(applicationLogName, 'a', 10000000, 1000)

import logging
applicationLogFileHandler.setLevel(logging.DEBUG)

from cherrypy import _cplogging
applicationLogFileHandler.setFormatter(_cplogging.logfmt)

cherrypy.log.error_log.addHandler(applicationLogFileHandler)

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

简化一下：

import os
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()
if hostname not in app_roots:
    cherrypy.log("The hostname %r does not have an app_root entry in "
                 "raspberry.py.  Exiting early." % hostname)
    sys.exit()

sys.path.append(app_roots[hostname])
os.chdir(app_root)

cherrypy.config.update({
    'environment': 'embedded',
    'log.access_file': "{0}/raspberry.access.log".format(app_roots[hostname]),
    'log.error_file': "{0}/raspberry.error.log".format(app_roots[hostname]),
    })

from web.controllers.root import RaspberryRequestHandler
application = cherrypy.tree.mount(RaspberryRequestHandler(), '/')
# Insert log changes here
cherrypy.engine.start()

如果您希望每天使用不同的日志，请按照http://www.cherrypy.org/wiki/Logging#CustomHandlers中的说明使用RotatingFileHandler。我认为您遗漏的重要一点是，您应该在之后仅使用app.log来解决问题你已经实例化你的应用程序（例如通过tree.mount（），如上所述），但之前 engine.start。也就是说，对于错误日志：

application = cherrypy.tree.mount(RaspberryRequestHandler(), '/') log = application.log log.error_file = "" # Make a new RotatingFileHandler for the error log. fname = "{0}/raspberry.error.log".format(app_roots[hostname]) h = handlers.RotatingFileHandler(fname, 'a', 10000000, 1000) h.setLevel(DEBUG) h.setFormatter(_cplogging.logfmt) log.error_log.addHandler(h) cherrypy.engine.start()
