使用 Firefox OS 作为网络服务器 [英] Use Firefox OS as web server

问题描述

对于一个艺术项目，我想要多个可以输出声音的分布式设备.Firefox OS 设备似乎是最佳选择.他们带来了必要的硬件，我非常了解 HTML 和 JS.但我还需要一个控制网络服务器.

For an art project, I'd like to have multiple distributed devices that can output sound. Firefox OS devices seem optimal. They bring the necessary hardware and I know HTML and JS very well. But I also need a control web server.

据我所知，Firefox OS 设备可以充当 WiFi 接入点(共享互联网").但是，它不能作为加入网络的其他设备的小型网络服务器 - 没有任何互联网连接.原生应用的 API 似乎不够强大.

From my understanding, a Firefox OS device can act as an WiFi access point ("Share Internet"). However, it cannot act as a small web server for other devices that join the network – without any internet connection. The APIs for native apps seem just not to be powerful enough.

但也许我错了(我想是).那么，Firefox OS 设备能否作为小型网络服务器运行?

But maybe I am mistaken (I would like to be). So, is a Firefox OS device able to run as a small web server?

推荐答案

httpd.js 对我来说不是开箱即用的.但它让我走上了正轨.然后我找到了 this 并经过一些调整和更新的代码，我得到了一个超级简单的服务器解决方案.

httpd.js did not work out-of-the-box for me. But it brought me on the right track. I then found this and after a little bit of tweaking and updating of the code, I got a super-simple server solution.

function startListen(){
  console.log("Initializing server");
  var socketServer = navigator.mozTCPSocket.listen(8080);

  socketServer.onconnect = function(conn){
    console.log("connected", conn, conn.ondata);
    conn.ondata = function(ev){
      console.log("Got request: ", ev);   
      conn.send("Ok. Got client on port " + conn.port);
      conn.close();
    };
    conn.onclose = function(ev){
      console.log("Client left:", ev);
    }
  };
  socketServer.onerror = function(ev){
    console.log("Failed to start: ", ev);
  };
}
startListen();

需要tcp-socket权限.

使用此代码，我可以在 Firefox OS 模拟器中启动它，引导我的浏览器打开 http://localhost:8080 并获得答案并登录控制台.

With this code, I was able to start this in the Firefox OS simulator, direct my browser to open http://localhost:8080 and get an answer and logs in the console.

附注.这也适用于真实设备.不幸的是，需要一个单独的接入点.虽然 Firefox OS 本身可以作为热点工作，但在该模式下它既不能作为客户端也不能作为服务器(传出连接没有正确路由，传入连接被拒绝).

PS. This also works on a real device. Unfortunately, a separate access point is needed. While Firefox OS can work as a hotspot itself, it can neither be client or server in that mode (outgoing connections are not routed properly and incoming connections are refused).
