将websockets与标准http.Server集成

Question

我有一个简单的Web服务器一样

var http = require('http'),
    url = require('url');
var server = http.createServer(function (req, res) {
  var uri = url.parse(req.url).pathname;
  if (uri == '/') {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello World\n');
    return;
  }

  res.writeHead(404, {'Content-Type': 'text/plain'});
  res.end('File not found');
});
server.listen(0, '127.0.0.1');

我现在想将一条路径(比方说/ws)连接到一个websocket,但不要修改服务器的其余部分.

但是,ws似乎要求我设置一个专用服务器(包括所有必需的服务器,如SSL终止,安全配置和端口分配).

如何终止/wswebsocket实现的路径？

Answer 1

我建议使用websocket包,它是一个

Websocket客户端和服务器库,实现RFC 6455中指定的WebSocket协议.

这就是我想要的,所以这就是我使用它的原因.这是非常轻松的使用,我实际上使用纯javascript websockets从html客户端做node.js的wss和ws连接.

git项目是活跃的,当我发布问题时,我在同一天收到了回复.上面链接中的一个示例显示了它是多么简单:

var WebSocketServer = require('websocket').server;
var http = require('http');

var server = http.createServer(function(request, response) {
    console.log((new Date()) + ' Received request for ' + request.url);
    response.writeHead(404);
    response.end();
});
server.listen(8080, function() {
    console.log((new Date()) + ' Server is listening on port 8080');
});

wsServer = new WebSocketServer({
    httpServer: server,
    autoAcceptConnections: false
});

function originIsAllowed(origin) {
  // put logic here to detect whether the specified origin is allowed.
  return true;
}

wsServer.on('request', function(request) {
    if (!originIsAllowed(request.origin)) {
      // Make sure we only accept requests from an allowed origin
      request.reject();
      console.log((new Date()) + ' Connection from origin ' + request.origin + ' rejected.');
      return;
    }

    var connection = request.accept('echo-protocol', request.origin);
    console.log((new Date()) + ' Connection accepted.');
    connection.on('message', function(message) {
        if (message.type === 'utf8') {
            console.log('Received Message: ' + message.utf8Data);
            connection.sendUTF(message.utf8Data);
        }
        else if (message.type === 'binary') {
            console.log('Received Binary Message of ' + message.binaryData.length + ' bytes');
            connection.sendBytes(message.binaryData);
        }
    });
    connection.on('close', function(reasonCode, description) {
        console.log((new Date()) + ' Peer ' + connection.remoteAddress + ' disconnected.');
    });
});

但是,我应该注意,子协议并不明显,因为没有例子.这个项目的git网站上有一些问题可以引导你朝着正确的方向前进.
