node . js插座.未捕获类型错误:Object #<Server>没有方法'close'"

Node.js Socket.IO "Uncaught TypeError: Object #<Server> has no method 'close'"

本文关键字：Server 有方法 quot close 插座 js 类型 Object 错误 node      更新时间：2023-09-26

我正在尝试关闭与套接字关联的http服务器。使用mySocketIoInstance.close()，但是我得到以下错误:

 Uncaught TypeError: Object #<Server> has no method 'close'
  at Socket.<anonymous> (/home/jackson/projects/tcg/test/server/ServerLobbySpec.js:35:20)

这里是我试图关闭它的地方:

'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();
            });
        });
    });
});

我试着注释出lobby和socket代码，只是console.log 'd io.close，得到undefined。

我的版本是1.0.6。根据socket.io/test/socket.io.js(也是1.0.6)，我应该能够以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完全一样。请建议。

在示例和您包含的测试中，它显示了一个套接字。用服务器对象构造IO对象，该服务器对象已以不同的方式初始化。

试试这个: 

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

完整示例取自发布时的链接:

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);
  });
});
