没有用这个基本的socket.io + redis设置接收事件？

Question

我有一个简单的socket.io服务器使用socket.io-redis,一个socket.io-emitter,我运行redis(这对我来说是全新的,我在Windows上,我下载了redis并打开了redis-server .exe和redis-cli.exe).通过带有命令的redis CLI,monitor我看到服务器已连接,并且事件从发射器到达redis,但从test-server.js不记录任何内容.我还需要做什么？socket.io服务器是否需要订阅redis？

Redis输出 "publish" "socket.io#/#" "\x93\xa7emitter\x83\xa4type\x02\xa4data\x92\xa4test\xa9some data\xa3nsp\xa1/\x82\xa5rooms\x90\xa5flags\x80"

测试server.js

var server = require('http').Server();
var io = require('socket.io')(server);
var redis = require('socket.io-redis');

io.adapter(redis({ host: '127.0.0.1', port: 6379 }));
io.on('connection', function(socket){
    console.log('client connected'); // Works
    socket.emit('connect','test'); // Works
});
io.on('test', function(socket){
    console.log('test came in'); // Works
});
server.listen(3000);

测试emit.js

var io = require('socket.io-emitter')({
    host:'localhost',
    port:'6379'
});
setInterval(function(){
    io.emit('test', 'some data');
    console.log('emitted');
}, 5000);

答案是这socket.io-emitter不是我这个测试用例所需要的。它直接连接到redis。在下面的示例中，我现在使用通常的方式socket.io-client，所有事件都正确到达服务器，并且两个服务器和两个客户端分别连接到不同的服务器，io.emit两个客户端现在都收到事件。伟大的！

测试发射.js

var PORT = 3000;
var HOST = 'http://localhost';
var port = parseInt(process.argv[2]) || PORT;
var io = require('socket.io-client');
var socket = io.connect(HOST + ':' + port);

socket.on('connect', function () {
    console.log('connected, sending message');
    socket.emit('message', 'message from client');
    socket.on('message', function(data) {
        console.log('new message received: '+data);
    });
});

测试服务器.js

var port = parseInt(process.argv[2]) || 3000;
console.log('server listens on port ' + port);
var io = require('socket.io').listen(port);
var redis = require('socket.io-redis');
var adapter = redis({ host: '127.0.0.1', port: 6379 });
io.adapter(adapter);
io.on('connection', function(socket){
    console.log('client connected');
    io.emit('message', 'client logged in on '+port+' and this message will be send to all clients');
    socket.on('message', function(d){
        console.log('message from socket:',d);
    });
});

启动 4 个不同的终端并运行：

$ node test-server 3000
$ node test-server 3001
$ node test-emit 3000
$ node test-emit 3001
