我正在使用 Python3 并使用以下代码发出请求:
try:
resp = self.s.get(url, proxies=self.proxies)
return resp.text
except ConnectTimeout:
self.logger.exception('{}: connection timeout!'.format(self.name))
except ConnectionError:
self.logger.exception('{}: ConnectionError!'.format(self.name))
except RemoteDisconnected:
self.logger.exception('{}: RemoteDisconnected'.format(self.name))
except MaxRetryError:
self.logger.exception('{}: MaxRetryError'.format(self.name))
except Exception as e:
self.logger.exception(e)
如果我在 session().get(url, proxies=proxies) 期间遇到异常,我会在日志文件中看到以下内容:
2018-04-20 17:14:27 | RF5MR: ConnectionError!

但是我想要得到的只是记录的字符串:
2018-04-20 17:14:27 | RF5MR:连接错误!
您能否指出我的错误在哪里,以及如何抑制这些异常文本并只获取我想要记录的文本?
非常感谢!
最佳答案
不要调用 self.logger.exception
,而是调用 self.logger.error
。
异常
记录消息和跟踪。所有其他日志方法仅按照特定于该方法的优先级记录消息。
