var helper = {}; exports.helper = helper; var path = require(“path”); var log4js = require(‘log4js’); var fs = require(“fs”);

var logDirectory = __dirname + ‘/log’;

// ensure log directory exists fs.existsSync(logDirectory) || fs.mkdirSync(logDirectory);

/*ar strs = fs.readFileSync(path.join(__dirname, ‘log4js.json’),‘utf8’);

console.log(strs); var objConfig = JSON.parse(fs.readFileSync(path.join(__dirname, ‘log4js.json’), “utf8”)); */

log4js.configure({ “customBaseDir” :path.join(__dirname, ‘log/’), “customDefaultAtt” :{ “type”: “dateFile”, “absolute”: true, “alwaysIncludePattern”: true }, “appenders”: [ {“type”: “console”, “category”: “console”}, {“pattern”: “debug/yyyyMMddhh.txt”, “category”: “logDebug”}, {“pattern”: “info/yyyyMMddhh.txt”, “category”: “logInfo”}, {“pattern”: “warn/yyyyMMddhh.txt”, “category”: “logWarn”}, {“pattern”: “err/yyyyMMddhh.txt”, “category”: “logErr”} ], “replaceConsole”: true, “levels”:{ “logDebug”: “DEBUG”, “logInfo”: “DEBUG”, “logWarn”: “DEBUG”, “logErr”: “DEBUG”} });

var logDebug = log4js.getLogger(‘logDebug’); var logInfo = log4js.getLogger(‘logInfo’); var logWarn = log4js.getLogger(‘logWarn’); var logErr = log4js.getLogger(‘logErr’);

helper.writeDebug = function(msg){ if(msg == null) msg = “”; logDebug.debug(msg); };

helper.writeInfo = function(msg){ if(msg == null) msg = “”; logInfo.info(msg); };

helper.writeWarn = function(msg){ if(msg == null) msg = “”; logWarn.warn(msg); };

helper.writeErr = function(msg, exp){ if(msg == null) msg = “”; if(exp != null) msg += “\r\n” + exp; logErr.error(msg); };

// 配合express用的方法 modules.exports.use = function(app) { //页面请求日志, level用auto时,默认级别是WARN app.use(log4js.connectLogger(logInfo, {level:‘debug’, format:’:method :url’})); }

错误：

{
  "appenders": [
    {
      "type": "clustered",
      "appenders": [
        {
          "type": "dateFile",
          "filename": "logs/access.log",
          "pattern": "-yyyy-MM-dd",
          "category": "http"
        },
        {
          "type": "file",
          "filename": "logs/app.log",
          "maxLogSize": 10485760,
          "numBackups": 3
        },
        {
          "type": "logLevelFilter",
          "level": "ERROR",
          "appender": {
            "type": "file",
            "filename": "logs/errors.log"
          }
        }
      ]
    }
  ]
}

then in app.js

// replace morgan with the log4js connect-logger
log4js.configure('config/log4js.json', { reloadSecs: 300 });
app.use(log4js.connectLogger(log4js.getLogger("http"), { level: 'auto' }));
