Python HTTP请求和调试级别日志记录到日志文件 [英] Python HTTP request and debug level logging to the log file
问题描述
我很难在HTTP请求的日志文件中获取DEBUG级别的日志，例如从控制台获取日志:
DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): URI:443
DEBUG:urllib3.connectionpool:URL:443 "POST /endpoint HTTP/1.1" 200 None
以下代码:
import logging
from logging.handlers import TimedRotatingFileHandler
_logger = logging.getLogger(__name__)
def setup_logging(loglevel):
logFormatter = logging.Formatter("%(asctime)s [%(threadName)-12.12s] [%(levelname)-5.5s] %(message)s")
if loglevel is not None:
if loglevel == 10:
http.client.HTTPConnection.debuglevel = 1
logformat = "%(asctime)s [%(threadName)-12.12s] [%(levelname)-5.5s] %(message)s"
logging.basicConfig(level=loglevel, stream=sys.stdout, format=logformat, datefmt="%Y-%m-%d %H:%M:%S")
fileHandler = logging.handlers.TimedRotatingFileHandler("{0}/{1}.log".format(logPath, logFileName), when="midnight")
fileHandler.setFormatter(logFormatter)
_logger.setLevel(logging.DEBUG)
_logger.addHandler(fileHandler)
当我用logging.DEBUG调用它时，日志文件将只包含我在代码中指定为_logger.info或_logger.debug的内容，与控制台日志输出没有类似之处.
PS. 示例代码我怎么称呼它:
def main(args):
args = parse_args(args)
cfg = config(args.env)
setup_logging(logging.DEBUG, cfg)
requests.get("https://stackoverflow.com/a/58769712/100297")
您要在错误的位置添加处理程序和级别更改.
Python日志记录模块根据记录器对象的名称和这些名称中是否存在.分隔符，将其视为存在于层次结构中的对象.逻辑上，记录器的名称"foo.bar.baz"被放置为foo.bar和foo的子级(如果存在).根记录器是层次结构的基础，它没有名称.您可以使用logging.getLogger()访问它(没有参数，尽管''和None也可以使用).
现在，在记录消息时，首先，消息必须通过记录器的有效级别.如果它们通过了，则只要消息清除了找到的每个处理程序的级别，便会将消息从当前记录器传递到每个记录器的处理程序，直到根.
要查找有效级别，请遍历层次结构以找到具有级别集的最近记录器对象；如果没有，则消息总是通过.在遍历层次结构以查找处理程序时，日志对象可能会阻止传播(propagate设置为False)，此时遍历停止.
在尝试处理urllib3.connectionpool()的消息时，需要将处理程序放在以下三个位置之一:urllib3.connectionpool的记录器，urllib3的记录器或根记录器.您的代码不这样做.
您改为在自己的记录器上使用其他名称设置处理程序:
_logger = logging.getLogger(__name__)
保证与根记录器不匹配(__name__必须为空，永远不会这样)或urllib3或urllib3.connectionpool记录器(这意味着您的模块也称为urllib3或urllib3.connectionpool).
由于urllib3.connectionpool日志消息不在路径中，因此您的处理程序将永远不会收到这些消息.
相反，您要配置 root记录器:
fileHandler = logging.handlers.TimedRotatingFileHandler("{0}/{1}.log".format(logPath, logFileName), when="midnight")
fileHandler.setFormatter(logFormatter)
root = logging.getLogger()
root.setLevel(logging.DEBUG)
root.addHandler(fileHandler)
您可以将每个 handler 的日志级别设置为要在该处理程序上看到的日志级别，而不是在根记录器上(或除根记录器之外).请记住，在根记录器上设置的级别用于确定层次结构中其他未直接设置级别的记录器的有效级别，并且该有效级别充当所有邮件的高水位标记".如果将根记录程序设置为INFO，并且未配置其他处理程序，则您的处理程序将永远不会看到DEBUG消息.根记录器的默认级别为WARNING.
您通常只想在模块中使用命名记录器来生成日志消息，并将所有处理程序置于根目录下.还有其他任何专门的方法，可以高级"使用记录器模块(例如，专门用于urllib3日志消息的专用，单独的处理程序，或者通过将其最低级别的记录器对象设置为propagate = False来使整个程序包静音).
最后，logging.basicConfig()也会配置根记录器，但如果根记录器上已经没有处理程序，则也将配置 .如果使用force=True，则basicConfig()将删除所有现有的处理程序，然后在根目录上配置这些处理程序.它将始终创建一个Formatter()实例并将其设置在所有处理程序上.
您可以将basicConfig()用于您的根记录器所需的 all :
import http.client
import logging
import os.path
import sys
from logging.handlers import TimedRotatingFileHandler
def setup_logging(loglevel):
# the file handler receives all messages from level DEBUG on up, regardless
fileHandler = TimedRotatingFileHandler(
os.path.join(logPath, logFileName + ".log"),
when="midnight"
)
fileHandler.setLevel(logging.DEBUG)
handlers = [fileHandler]
if loglevel is not None:
# if a log level is configured, use that for logging to the console
stream_handler = logging.StreamHandler(sys.stdout)
stream_handler.setLevel(loglevel)
handlers.append(stream_handler)
if loglevel == logging.DEBUG:
# when logging at debug level, make http.client extra chatty too
# http.client *uses `print()` calls*, not logging.
http.client.HTTPConnection.debuglevel = 1
# finally, configure the root logger with our choice of handlers
# the logging level of the root set to DEBUG (defaults to WARNING otherwise).
logformat = "%(asctime)s [%(threadName)-12.12s] [%(levelname)-5.5s] %(message)s"
logging.basicConfig(
format=logformat, datefmt="%Y-%m-%d %H:%M:%S",
handlers=handlers, level=logging.DEBUG
)
旁注:http.client库不使用logging 来输出调试消息；它将始终使用print()来输出这些内容.如果您希望看到这些消息出现在日志中，则需要对库进行猴子补丁处理，并添加一个可选的print() global:
import http.client
import logging
http_client_logger = logging.getLogger("http.client")
def print_to_log(*args):
http_client_logger.debug(" ".join(args))
# monkey-patch a `print` global into the http.client module; all calls to
# print() in that module will then use our print_to_log implementation
http.client.print = print_to_log
应用上述http.client技巧和setup_logging(logging.DEBUG)后，当我使用requests.get("https://stackoverflow.com/a/58769712/100297")时，我看到以下日志同时出现在stdout和文件中:

您可以使用以下文件复制该文件:
import requests
import sys
logPath, logFileName = "/tmp", "demo"
level = logging.DEBUG if "-v" in sys.argv else None
setup_logging(level)
requests.get("https://stackoverflow.com/a/58769712/100297")
在上面的代码之外添加了.然后，您可以使用python <script.py> -v将级别设置为详细，并将其与python <script.py>进行比较，而完全没有设置级别.
I have a hard time to get DEBUG level logs in a log file for HTTP request like those from console like:
DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): URI:443
DEBUG:urllib3.connectionpool:URL:443 "POST /endpoint HTTP/1.1" 200 None
for the code below:
import logging
from logging.handlers import TimedRotatingFileHandler
_logger = logging.getLogger(__name__)
def setup_logging(loglevel):
logFormatter = logging.Formatter("%(asctime)s [%(threadName)-12.12s] [%(levelname)-5.5s] %(message)s")
if loglevel is not None:
if loglevel == 10:
http.client.HTTPConnection.debuglevel = 1
logformat = "%(asctime)s [%(threadName)-12.12s] [%(levelname)-5.5s] %(message)s"
logging.basicConfig(level=loglevel, stream=sys.stdout, format=logformat, datefmt="%Y-%m-%d %H:%M:%S")
fileHandler = logging.handlers.TimedRotatingFileHandler("{0}/{1}.log".format(logPath, logFileName), when="midnight")
fileHandler.setFormatter(logFormatter)
_logger.setLevel(logging.DEBUG)
_logger.addHandler(fileHandler)
When I will call it with logging.DEBUG log file will only contains whatever I will specify in the code as _logger.info or _logger.debug nothing similar like for the console log output.
PS. Example code how do I call it:
def main(args):
args = parse_args(args)
cfg = config(args.env)
setup_logging(logging.DEBUG, cfg)
requests.get("https://stackoverflow.com/a/58769712/100297")
You are adding your handlers and level changes in the wrong place.
The Python logging module treats logger objects as existing in a hierarchy, based on their name and the presence of . delimiters in those names. The name "foo.bar.baz" for a logger is logically placed as child of foo.bar and of foo, should they exist. At the base of the hierarchy is the root logger, which has no name. You access it with logging.getLogger() (no arguments, although '' and None also would work).
Now, when logging messages, first the message has to pass the effective level of the logger. If they passed that the messages are passed to the handlers on every logger from the current logger down to the root, provided they clear the level of each handler found.
To find the effective level, the hierarchy is traversed to find the nearest logger object with a level set; if there are none then messages always pass. When traversing the hierarchy to find handlers, a log object can block propagation (propagate is set to False), at which point traversing stops.
When you are trying to handle messages for urllib3.connectionpool(), you need to put a handler on one of three locations: the logger for urllib3.connectionpool, for urllib3 or the root logger. Your code doesn't do that.
You instead set up your handlers on your own logger with a different name:
_logger = logging.getLogger(__name__)
That is guaranteed to not match the root logger (__name__ would need to be empty, that's never the case) nor the urllib3 or urllib3.connectionpool loggers (which would mean your module is also called urllib3 or urllib3.connectionpool).
Because it is not in the path that urllib3.connectionpool log messages would follow, your handlers are never going to be given those messages.
Instead, you want to configure the root logger:
fileHandler = logging.handlers.TimedRotatingFileHandler("{0}/{1}.log".format(logPath, logFileName), when="midnight")
fileHandler.setFormatter(logFormatter)
root = logging.getLogger()
root.setLevel(logging.DEBUG)
root.addHandler(fileHandler)
You could just set the log level of each handler to a log level you want to see on that handler, rather than on the root logger (or in addition to the root logger). Remember that the level set on the root logger is used to determine the effective level of other loggers in the hierarchy that don't have a level set directly and that the effective level works as a 'high water mark' for all messages. If the root logger is set to INFO, and no other handlers are configured, then your handlers will never see DEBUG messages. The default level for the root logger is WARNING.
You usually only ever want to use named loggers in your modules to produce log messages, and put all your handlers on the root. Anything else is specialised, 'advanced' use of the logger module (e.g. a dedicated, separate handler just for the urllib3 log messages, or silencing a whole package by setting their lowest-level logger object to propagate = False).
Finally, logging.basicConfig() configures the root logger too, but only if there are no handlers on the root logger already. If you use force=True then basicConfig() will remove all existing handlers, then configure the handlers on the root. It'll always create a Formatter() instance and set it on all handlers.
You could use basicConfig() for all your root logger needs:
import http.client
import logging
import os.path
import sys
from logging.handlers import TimedRotatingFileHandler
def setup_logging(loglevel):
# the file handler receives all messages from level DEBUG on up, regardless
fileHandler = TimedRotatingFileHandler(
os.path.join(logPath, logFileName + ".log"),
when="midnight"
)
fileHandler.setLevel(logging.DEBUG)
handlers = [fileHandler]
if loglevel is not None:
# if a log level is configured, use that for logging to the console
stream_handler = logging.StreamHandler(sys.stdout)
stream_handler.setLevel(loglevel)
handlers.append(stream_handler)
if loglevel == logging.DEBUG:
# when logging at debug level, make http.client extra chatty too
# http.client *uses `print()` calls*, not logging.
http.client.HTTPConnection.debuglevel = 1
# finally, configure the root logger with our choice of handlers
# the logging level of the root set to DEBUG (defaults to WARNING otherwise).
logformat = "%(asctime)s [%(threadName)-12.12s] [%(levelname)-5.5s] %(message)s"
logging.basicConfig(
format=logformat, datefmt="%Y-%m-%d %H:%M:%S",
handlers=handlers, level=logging.DEBUG
)
Side note: the http.client library does not use logging to output debug messages; it will always use print() to output those. If you want to see those messages appear in your logs, you'll need to monkey-patch the library, adding in an alternative print() global:
import http.client
import logging
http_client_logger = logging.getLogger("http.client")
def print_to_log(*args):
http_client_logger.debug(" ".join(args))
# monkey-patch a `print` global into the http.client module; all calls to
# print() in that module will then use our print_to_log implementation
http.client.print = print_to_log
With the above http.client trick applied and setup_logging(logging.DEBUG), I see the following logs appear both on stdout and in the file when I use requests.get("https://stackoverflow.com/a/58769712/100297"):

You can reproduce this with a file with:
import requests
import sys
logPath, logFileName = "/tmp", "demo"
level = logging.DEBUG if "-v" in sys.argv else None
setup_logging(level)
requests.get("https://stackoverflow.com/a/58769712/100297")
added in addition to the code above. You can then use python <script.py> -v to set the level to verbose and compare that to python <script.py> with the level not set at all.
