let http = require("http"),
    fs = require("fs"),
    file = "access.log",
    retValue = Buffer.from("你好阿"),
    date = new Date(),
    day = date.getDate(),
    month = date.getMonth(),
    year = date.getFullYear(),
    hours = date.getHours(),
    seconds = date.getMinutes(),
    milis = date.getSeconds(),
    zone = "+8400";

let server  = http.createServer(function(req,res){
}).listen(8080)

server.on("request",function(req,res){
    function getLog(req,status,size){
      let rizhi = "",
          ip,
          time,
          method,
          page,
          protocol,
          statusCode,
          userAgent;
      ip = req.connection.remoteAddress;
      time = `[${day}/${month}/${year}:${hours}:${seconds}:${milis} ${zone}]`;
      method = req.method;
      page = req.url;
      protocol = req.httpVersion;
      statusCode = status;
      size = size;
      userAgent = req.headers["user-agent"];
      rizhi = `${ip} - - ${time} "${method} ${page} HTTP${protocol}" ${statusCode} ${size}
        "-" "${userAgent}"`;
          console.log(rizhi)
        return rizhi;
    }
    function writeLog(f,req,res,status,size,fn){
        let rizhi = fn(req,status,size);
        fs.writeFileSync(file,rizhi)
    }
    if(req.method.toLowerCase() === 'get'){
      if(req.url === '/app'){
          let status = 200;
          let size = 20000;
          writeLog(file,req,res,status,size,getLog)
      }
    }
})

效果：
