Python中处理unchecked未捕获异常实例

2020-11-27 来源：华拓网

Talk Is Cheap

和Java一样,python也提供了对于checked exception和unchecked exception. 对于checked exception,我们通常使用try except可以显示解决,对于unchecked 异常,其实也是提供回调或者是钩子来帮助我们处理的,我们可以在钩子里面记录崩溃栈追踪或者发送崩溃数据.

下面代码可以实现python unchecked exception回调,并输出日志信息.

Show Me The Code

代码如下:

#!/usr/bin/env python
# coding=utf-8
import os, sys
import logging
logger = logging.getLogger(__name__)
handler = logging.StreamHandler(stream=sys.stdout)
logger.addHandler(handler)

def handle_exception(exc_type, exc_value, exc_traceback):
if issubclass(exc_type, KeyboardInterrupt):
sys.__excepthook__(exc_type, exc_value, exc_traceback)
return
logger.error("Uncaught exception", exc_info=(exc_type, exc_value, exc_traceback))

sys.excepthook = handle_exception
if __name__ == "__main__":
raise RuntimeError("Test unhandled Exception")
