在日志模块(如果是自定义模块)中启用stack_info。

api_logger.exceptionLog("*Input your Custom error message*",stack_info=True)

日志记录有一个好处。SiggyF的答案没有显示的异常是，你可以传递一个任意的消息，日志仍然会显示所有异常细节的完整跟踪:

import logging
try:
    1/0
except ZeroDivisionError:
    logging.exception("Deliberate divide by zero traceback")

默认情况下(在最近的版本中)只是将错误打印到sys. log行为。Stderr，它看起来像这样:

>>> import logging
>>> try:
...     1/0
... except ZeroDivisionError:
...     logging.exception("Deliberate divide by zero traceback")
... 
ERROR:root:Deliberate divide by zero traceback
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ZeroDivisionError: integer division or modulo by zero

我的方法是创建一个上下文管理器，记录并引发异常:

import logging
from contextlib import AbstractContextManager


class LogError(AbstractContextManager):

    def __init__(self, logger=None):
        self.logger = logger.name if isinstance(logger, logging.Logger) else logger

    def __exit__(self, exc_type, exc_value, traceback):
        if exc_value is not None:
            logging.getLogger(self.logger).exception(exc_value)


with LogError():
    1/0

您可以将记录器名称或记录器实例传递给LogError()。默认情况下，它将使用基本日志记录器(通过将None传递给logging.getLogger)。 还可以简单地添加一个开关来引发错误或只记录错误。

如果您的应用程序以其他方式记录日志-不使用日志模块?

现在，traceback可以用在这里。

import traceback

def log_traceback(ex, ex_traceback=None):
    if ex_traceback is None:
        ex_traceback = ex.__traceback__
    tb_lines = [ line.rstrip('\n') for line in
                 traceback.format_exception(ex.__class__, ex, ex_traceback)]
    exception_logger.log(tb_lines)

在Python 2中使用它: 试一试: #你的函数调用在这里 Exception as ex: _， _， ex_traceback = sys.exc_info() ex_traceback log_traceback(例) 在Python 3中使用它: 试一试: X = get_number() Exception as ex: log_traceback(特异)

一个干净的方法是使用format_exc()，然后解析输出以获得相关部分:

from traceback import format_exc

try:
    1/0
except Exception:
    print 'the relevant part is: '+format_exc().split('\n')[-2]

问候

您可以记录堆栈跟踪而不出现异常。

https://docs.python.org/3/library/logging.html#logging.Logger.debug

The second optional keyword argument is stack_info, which defaults to False. If true, stack information is added to the logging message, including the actual logging call. Note that this is not the same stack information as that displayed through specifying exc_info: The former is stack frames from the bottom of the stack up to the logging call in the current thread, whereas the latter is information about stack frames which have been unwound, following an exception, while searching for exception handlers.

例子:

>>> import logging
>>> logging.basicConfig(level=logging.DEBUG)
>>> logging.getLogger().info('This prints the stack', stack_info=True)
INFO:root:This prints the stack
Stack (most recent call last):
  File "<stdin>", line 1, in <module>
>>>
