1, set the log level and log output file name in the configuration file

Because it can facilitate the development of a daily log to view information, but can also prevent a single log file log information accumulated more and more, it will save the day, the day of the log information to a log file
2, Configuration options log level LOG_LEVEL, log file path LOG_FILE, I am here to set the level to WARNING
2, the logging module introduced in the program, the content needs to be output from the output log log
I configured with the WARNING level, then I 1 100 and which is defined when an exception (logging.warning) to WARNING output is equal to or higher than the level of information can be outputted to the log I, information is lower than the output level is less than my log information
