[英]Express websockets on message get cookie info
I have an express web socket application. 我有一个快速的Web套接字应用程序。
In the onmessage
function, I would like to access the cookies of the client that sent the message. 在
onmessage
函数中,我想访问发送消息的客户端的cookie。
The reason for this is that I'm making a game and I have the user login. 这样做的原因是我正在做游戏,并且已经有用户登录名。 I need to check what to
name
cookie is so that I control the correct player. 我需要检查Cookie的
name
,以便控制正确的播放器。
This is what I've got so far: 到目前为止,这是我得到的:
var express = require('express');
var expressWs = require('express-ws');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var app = express();
app.use(cookieParser('secretkey123'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true
}))
expressWs = expressWs(app);
app.get('/', function(req, res) {
// stuff for logging in
})
app.post('/', function(req, res) {
// stuff for logging in
})
app.get('/logout', function(req, res) {
res.clearCookie('name');
res.redirect('/');
// more stuff for logging in
})
app.ws('/ws', function(ws, req) {
ws.on('open', function() {
// how do I check when a connection is opened?
})
ws.on('message', function(msg) {
// who sent the message? how do I get the cookie info to check the user who send it?
})
ws.on('close', function() {
// the've disconnected
})
})
var server = app.listen(8000, function () {
var host = server.address().address
var port = server.address().port
})
Is this possible? 这可能吗?
Also, where do I check when a websocket connection is opened? 另外,在哪里检查何时打开Websocket连接?
I tried the 'open' event but it doesn't seem to be working. 我尝试了“公开”活动,但似乎没有成功。
Thanks for the help in advance! 我在这里先向您的帮助表示感谢!
I figured out how to do it! 我想出了怎么做!
I forgot that the req
argument can be accessed inside the other functions. 我忘记了
req
参数可以在其他函数中访问。
This means in the on message function you can just do this: 这意味着在on message函数中,您可以执行以下操作:
ws.on('message', function(msg) {
req.cookies.username //do stuff
});
The connection open code can be done before you setup any of the events: 可以在设置任何事件之前完成连接打开代码:
app.ws('/ws', function(ws, req) {
// connection open code here
ws.on('message', function(msg) {
// connection message code here
})
})
