在Python中记录方法调用的更好方法? [英] Better way to log method calls in Python?

问题描述

我们可以编写某种日志装饰器，以回显函数/方法调用，如下所示:

We can code out some sort of logging decorator to echo function/method calls like the following:

def log(fn):
    ...

@log
def foo():
    ...

class Foo(object):
    @log
    def foo(self):
        ...

    @log
    def bar(self, a, b):
        ...

    @log
    def foobar(self, x, y, z):
        ...

但是，如果我们想记录方法调用而不在每个meth定义前放置那么多@log怎么办?是否有某种方法可以将一个装饰器放在类定义之上，以使其所有方法调用都进行装饰/记录?还是有其他更好且有趣的方法来代替装饰器呢?

But what if we are like to log method calls without putting that many @log in front of each meth definition? Is there some way to just put one decorator above a class definition to make all its method calls decorated/logged? Or are there some other better and interesting ways to do that instead of decorator?

推荐答案

请参见但是，正如对该问题的公认答案所指出的那样，通常这不是一个好主意.

However, as the accepted answer to that question points out, it generally isn't a good idea.

如果您决定采用面向方面的编程路线，建议从这里开始:任何AOP是否支持Python?

If you decide to go the aspect oriented programming route, I suggest starting here: Any AOP support library for Python?
