我在nodejs中使用socket.io,我能够从客户端向服务器发送数据。但是当我从服务器发出时,客户端似乎没有收到这个... 我错过了什么?
socket = io.listen(app);
socket.sockets.on('connection', function(client){
client.on('something-from-client', function(msg){
console.log(msg);
//do something.
client.emit('some-result',{"total":docs.length});
});
});
var socket = io.connect('http://localhost:9999');
socket.on('some-result', function(data){
console.log('received from server', data);
});
socket.emit("something-from-client", {"lat":lat, "lng":lng});

确定它正常工作,如果正在使用express,则需要在服务器端进行一些小的更改
var port = 8111;
var server = express.createServer();
io = require('socket.io').listen(server);
server.listen(port);
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
