Authenticate socket.io incoming connections with JWTs. This is useful if you are build a single page application and you are not using cookies as explained in this blog post: [Cookies vs Tokens. Getting auth right with Angular.JS](http://blog.auth0.com/2014/01/07/angularjs-authentication-with-cookies-vs-token/).
|
|
|
|
## Installation
|
|
|
|
```
|
|
npm install socketio-jwt
|
|
```
|
|
|
|
## Example usage
|
|
|
|
```javascript
|
|
// set authorization for socket.io
|
|
io.sockets
|
|
.on('connection', socketioJwt.authorize({
|
|
secret: 'your secret or public key',
|
|
timeout: 15000 // 15 seconds to send the authentication message
|
|
})).on('authenticated', function(socket) {
|
|
//this socket is authenticated, we are good to handle more events from it.
|
|
console.log('hello! ' + socket.decoded_token.name);
|
|
});
|
|
```
|
|
|
|
**Note:** If you are using a base64-encoded secret (e.g. your Auth0 secret key), you need to convert it to a Buffer: `Buffer('your secret key', 'base64')`
|
|
|
|
__Client side__:
|
|
|
|
```javascript
|
|
var socket = io.connect('http://localhost:9000');
|
|
socket.on('connect', function (socket) {
|
|
socket
|
|
.on('authenticated', function () {
|
|
//do other things
|
|
})
|
|
.emit('authenticate', {token: jwt}); //send the jwt
|
|
});
|
|
```
|
|
|
|
## One roundtrip
|
|
|
|
The previous approach uses a second roundtrip to send the jwt, there is a way you can authenticate on the handshake by sending the JWT as a query string, the caveat is that intermediary HTTP servers can log the url.
|
|
|
|
```javascript
|
|
var io = require("socket.io")(server);
|
|
var socketioJwt = require("socketio-jwt");
|
|
|
|
//// With socket.io < 1.0 ////
|
|
io.set('authorization', socketioJwt.authorize({
|
|
secret: 'your secret or public key',
|
|
handshake: true
|
|
}));
|
|
//////////////////////////////
|
|
|
|
//// With socket.io >= 1.0 ////
|
|
io.use(socketioJwt.authorize({
|
|
secret: 'your secret or public key',
|
|
handshake: true
|
|
}));
|
|
///////////////////////////////
|
|
|
|
io.on('connection', function (socket) {
|
|
// in socket.io < 1.0
|
|
console.log('hello!', socket.handshake.decoded_token.name);
|
|
|
|
// in socket.io 1.0
|
|
console.log('hello! ', socket.decoded_token.name);
|
|
})
|
|
```
|
|
|
|
For more validation options see [auth0/jsonwebtoken](https://github.com/auth0/node-jsonwebtoken).
|
|
|
|
__Client side__:
|
|
|
|
Append the jwt token using query string:
|
|
|
|
```javascript
|
|
var socket = io.connect('http://localhost:9000', {
|
|
'query': 'token=' + your_jwt
|
|
});
|
|
```
|
|
|
|
## Handling token expiration
|
|
|
|
__Server side__:
|
|
|
|
When you sign the token with an expiration time:
|
|
|
|
```javascript
|
|
var token = jwt.sign(user_profile, jwt_secret, {expiresInMinutes: 60});
|
|
```
|
|
|
|
Your client-side code should handle it as below.
|
|
|
|
__Client side__:
|
|
|
|
```javascript
|
|
socket.on("error", function(error) {
|
|
if (error.type == "UnauthorizedError" || error.code == "invalid_token") {
|
|
// redirect user to login page perhaps?
|
|
console.log("User's token has expired");
|
|
}
|
|
});
|
|
```
