javascript - Node.js Socket.IO "Uncaught TypeError: Object # has no method ' 关闭'"

Question

我尝试使用 mySocketIoInstance.close() 关闭与 socket.io 实例关联的 http 服务器，但出现以下错误:

 Uncaught TypeError: Object #<Server> has no method 'close'
  at Socket.<anonymous> (/home/jackson/projects/tcg/test/server/ServerLobbySpec.js:35:20)
  at Socket.Emitter.emit (/home/jackson/projects/tcg/node_modules/socket.io-client/node_modules/component-emitter/index.js:134:20)

  at Decoder.Emitter.emit (/home/jackson/projects/tcg/node_modules/socket.io-client/node_modules/socket.io-parser/node_modules/emitter/index.js:132:20)

这是我尝试关闭它的地方:

'use strict';

var http = require('http'),
    expect = require('chai').expect,
    socketIo = require('socket.io'),
    socketIoClient = require('socket.io-client'),
    ServerLobby = require('../../source/server/ServerLobby');

describe('ServerLobby', function () {

    var port = 2468,
        uri = 'http://localhost:' + port;

    describe('is connectable', function () {

        it('should connect', function (done) {

            var httpServer = http.Server().listen(port),
                io = socketIo(httpServer),
                lobby = new ServerLobby(io),
                socket = socketIoClient(uri + lobby.namespace);

            socket.on('connect', function () {

                // HERE
                io.close();
                // HERE

                done();
            });

        });

    });

});

我尝试注释掉lobby和socket代码，只是console.log'd io.close并得到未定义。

我的版本是1.0.6。根据 socket.io/test/socket.io.js (也是 1.0.6)，我应该能够通过以下方式关闭服务器:

var http = require('http').Server;
var io = require('..');
var expect = require('expect.js');

// ...

    it('should be able to close sio sending a srv', function() {
        var PORT = 54016;
        var srv = http().listen(PORT);
        var sio = io(srv);

        var clientSocket = client(srv, {
            reconnection: false
        });

        clientSocket.on('connect', function init() {
            expect(sio.nsps['/'].sockets.length).to.equal(1);

            // HERE
            sio.close();
            // HERE

        });

    });

我的设置看起来几乎一模一样。请指教。

在 examples在您包含的测试中，它显示了一个使用以不同方式初始化的服务器对象构造的 socket.io 对象。

试试这个:

var http = require('http').Server,
// ...
var httpServer = http().listen(port);

完整示例取自 link发布时:

var app = require('http').createServer(handler)
var io = require('socket.io')(app);
var fs = require('fs');

app.listen(80);

function handler (req, res) {
  fs.readFile(__dirname + '/index.html',
  function (err, data) {
    if (err) {
      res.writeHead(500);
      return res.end('Error loading index.html');
    }

    res.writeHead(200);
    res.end(data);
  });
}

io.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });
  socket.on('my other event', function (data) {
    console.log(data);
  });
});
