在aiohttp 2中指定日志请求格式 [英] specify log request format in aiohttp 2

问题描述

我正在将aiohttp 2与Python 3.6配合使用，并希望记录到应用程序的请求.

I'm using aiohttp 2 with Python 3.6 and want to log the requests coming to the application.

我做到了:

# use ISO timestamps
from time import gmtime
logging.Formatter.converter = gmtime
# create a formatter
ch = logging.StreamHandler()
formatter = logging.Formatter('%(asctime)s %(levelname)s %(name)s - %(message)s', '%Y-%m-%dT%H:%M:%S')
ch.setFormatter(formatter)

# show all emssages (default is WARNING)
logging.getLogger('aiohttp.access').setLevel(logging.DEBUG)
# attach the handler
logging.getLogger('aiohttp.access').addHandler(ch)

现在在应用程序运行时，我会收到以下格式的日志:

and now when the application is running I get a log in this format:

2017-04-19T16:02:17 INFO aiohttp.access - 127.0.0.1 - - [19/Apr/2017:16:02:17 +0000] "GET /test HTTP/1.1" 404 547 "-" "curl/7.51.0" 

message组件具有多余的时间戳，我想自定义其格式. 文档说应该可以，但我不知道该怎么做它确实有效，并且没有代码示例.

the message component has a redundant timestamp, and I'd like to customize its format. The documentation says it should be possible but I don't understand how to make it actually work and there are no code examples.

我仅发现此用法但具有:

mylogger = logging.Logger('aiohttp.access')
mylogger.setLevel(logging.DEBUG)
mylogger.addHandler(ch)

handler = app.make_handler(
        logger=mylogger,
        access_log_format='%r %s %b',
)

该应用程序根本不生成任何日志.我不明白make_handler到底能做什么，还有一个上一个问题没有帮助.

the application produces no log at all. I don't understand what make_handler does exactly, and a previous question doesn't help.

如何格式化日志的message部分并插入aiohttp文档中列出的元素?

How can I format the message part of the log and insert the elements listed in the aiohttp docs ?

推荐答案

您可以看到我的示例:

import asyncio
import logging

from aiohttp import web


mylogger = logging.getLogger('aiohttp.access')
mylogger.setLevel(logging.DEBUG)
ch = logging.StreamHandler()
mylogger.addHandler(ch)


async def handle(request):
    name = request.match_info.get('name', "Anonymous")
    text = "Hello, " + name
    return web.Response(text=text)

loop = asyncio.get_event_loop()

app = web.Application(loop=loop)
app.router.add_get('/', handle)
app.router.add_get('/{name}', handle)

loop.run_until_complete(
    loop.create_server(
        app.make_handler(access_log=mylogger,
                         access_log_format='%r %s %b'), '0.0.0.0', 8080))
loop.run_forever()
loop.close()

运行它并访问' http://127.0.0.1:8080/xmwd '，您将在您的控制台中看到GET /xmwd HTTP/1.1 200 11.

run it and access 'http://127.0.0.1:8080/xmwd', you will see GET /xmwd HTTP/1.1 200 11 in your console.
