python-使用bottle和cherrypy记录响应内容的长度

我正在使用带有Cherrypy(提供WSGI)的瓶子用于Web应用程序. CherryPy在此设置中不记录Web访问.目前,我几乎使用bottle hook plug-in记录所有内容,如下所示：

import bottle
from bottle import route, static_file, get, post, error, request, template, redirect, response, hook

@hook('after_request')
def log_after_request():
    try:
        length = response.content_length
    except:
        try:
            length = len(response.body)
        except:
            length = '???'
    print '{ip} - - [{time}] "{method} {uri} {protocol}" {status} {length}'.format(
        ip=request.environ.get('REMOTE_ADDR'),
        time=datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'),
        method=request.environ.get('REQUEST_METHOD'),
        uri=request.environ.get('REQUEST_URI'),
        protocol=request.environ.get('SERVER_PROTOCOL'),
        status=response.status_code,
        length=length,
    )

@route('/index.html')
def index_handler():
    return '<h1>Hello, world!</h1>'

app = bottle.default_app()
bottle.run(host='0.0.0.0', port='80', app=app, server='cherrypy', request_queue_size=300, debug=True)

这将日志条目提供给STDOUT,如下所示：

192.168.1.1 - - [2013-07-23 17:04:04] "GET /index.html HTTP/1.1" 200 0

这几乎是正确的,除了content-length始终为0.似乎bottle不知道cherrypy返回的content-length.这是正确的评估吗？更重要的是,有没有办法找回它,所以我可以将其记录下来？

我愿意使用更好的方法来使用bottle和cherrypy获取访问日志.

谢谢！

解决方法:

我可以想到几种方法,但是我认为这是最好的一种方法：使用中间件应用程序记录请求.

这是一个基于您问题中代码的完整示例. (我没有更改log_after_request；大多数操作在AccessLogMiddleware .__ call__中.)

import datetime
import bottle
from bottle import route, static_file, get, post, error, request, template, redirect, response, hook

# unchanged from OP
@route('/index.html')
def index_handler():
    return '<h1>Hello, world!</h1>'

# unchanged from OP
def log_after_request():
    try:
        length = response.content_length
    except:
        try:
            length = len(response.body)
        except:
            length = '???'
    print 'MYLOG:', '{ip} - - [{time}] "{method} {uri} {protocol}" {status} {length}'.format(
        ip=request.environ.get('REMOTE_ADDR'),
        time=datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'),
        method=request.environ.get('REQUEST_METHOD'),
        uri=request.environ.get('REQUEST_URI'),
        protocol=request.environ.get('SERVER_PROTOCOL'),
        status=response.status_code,
        length=length,
    )

# code I've added begins here
class AccessLogMiddleware(object):
    def __init__(self, app):
        self.app = app

    def __call__(self, e, h):
        # call bottle and store the return value
        ret_val = self.app(e, h)

        # log the request
        log_after_request()

        # return bottle's return value
        return ret_val


app = bottle.app()
logged_app = AccessLogMiddleware(app)
bottle.run(host='0.0.0.0', port='8000', app=logged_app)

这应该够了吧;如果没有,请告诉我,我会帮忙.
