无法保存代码Esprino NodeMCU

在摆弄文档并在混乱的网络上爬行了几乎一整天之后,我自己找到了一个解决方案。问题->

function main() {
  var wifi = require('Wifi');
  wifi.startAP("testing");
  wifi.save();
  var http = require('http');
  var led = Pin(5);
  return http.createServer(function (req, res) {
    var url = req.url;
    res.writeHead(200);
    if(url == "/on") {
      digitalWrite(led, 1);
      res.end("on");
    } else if(url == "/off") {
      digitalWrite(led, 0);
      res.end("off");
    } else {
      res.end('Lol');
    }
  }).listen(80);
}
function test() {
  console.log('Starting server');
  setTimeout(function() {
    var server = main();
    console.log(server);
  }, 5000);
}
E.on('init', function(){
 test();
});
save();
