我正在尝试编写一个简单的记录器但是我正在抛出异常。我想要一些关于为什么这个例子被抛出的建议,但也会欣赏一些设计建议(请记住,我想保持这个简单)。
代码:
import logging
import logging.handlers
class Logger:
@staticmethod
def log_to_file(logText):
logFile = logging.handlers.RotatingFileHandler('/var/log/sosms/sosmsd.log', 'a', 1000, 5)
formatter = logging.Formatter()
logFile.setFormatter(formatter)
logFile.emit(logText)
return
输出:
kyle@boxmunch:/var/log/sosms$ /etc/rc.local
Traceback (most recent call last):
File "/usr/lib/python2.7/logging/handlers.py", line 77, in emit
if self.shouldRollover(record):
File "/usr/lib/python2.7/logging/handlers.py", line 156, in shouldRollover
msg = "%s\n" % self.format(record)
File "/usr/lib/python2.7/logging/__init__.py", line 719, in format
return fmt.format(record)
File "/usr/lib/python2.7/logging/__init__.py", line 464, in format
record.message = record.getMessage()
AttributeError: 'str' object has no attribute 'getMessage'
Traceback (most recent call last):

Logger.Logger.log_to_file('SOSMSD starting..')
File "/git/sosms/sosmsd/Logger.py", line 14, in log_to_file
logFile.emit(logText)
File "/usr/lib/python2.7/logging/handlers.py", line 83, in emit
self.handleError(record)
File "/usr/lib/python2.7/logging/__init__.py", line 799, in handleError
record.filename, record.lineno))
AttributeError: 'str' object has no attribute 'filename'
答案 0 :(得分:3)
因为处理程序的.emit()
采用记录,而不是字符串。
http://docs.python.org/library/logging.handlers.html
您可能不想创建自己的记录器类,只需使用Logging.getLogger(__name__)
(或类似的)检索一个,并调用适当的方法(例如.error(logText)
)。
编辑:你绝对不希望每次登录时都创建一个新的处理程序,通常应该为每个应用程序创建一次。对于简单的情况,您只需使用logging.basicConfig()
。
