node.js – 使用节点js中的log4js在文件中写入日志

整个代码块将如下所示：

var log4js = require('log4js');

log4js.loadAppender('file');
log4js.addAppender(log4js.appenders.file('logs/cheese.log'),'cheese');

var logger = log4js.getLogger('cheese');

logger.setLevel('DEBUG');
logger.trace('Entering cheese tesTing');
logger.debug('Got cheese.');
logger.info('Cheese is Gouda.');
logger.warn('Cheese is quite smelly.');
logger.error('Cheese is too ripe!');
logger.fatal('Cheese was breeding ground for listeria.');
