使用 socket.io,我以一种简单的方式完成了这项工作。我假设您的应用程序有一个对象,比如说 MrBojangle,对我来说它被称为 Shished:
/**
* Shished singleton.
*
* @api public
*/
function Shished() {
};
Shished.prototype.getHandshakeValue = function( socket, key, handshake ) {
if( !handshake ) {
handshake = socket.manager.handshaken[ socket.id ];
}
return handshake.shished[ key ];
};
Shished.prototype.setHandshakeValue = function( socket, key, value, handshake ) {
if( !handshake ) {
handshake = socket.manager.handshaken[ socket.id ];
}
if( !handshake.shished ) {
handshake.shished = {};
}
handshake.shished[ key ] = value;
};
那么在你的授权方式上,我使用 MongoDB 进行会话存储:
io.set('authorization', function(handshake, callback) {
self.setHandshakeValue( null, 'userId', null, handshake );
if (handshake.headers.cookie) {
var cookie = connect.utils.parseCookie(handshake.headers.cookie);
self.mongoStore()
.getStore()
.get(cookie['connect.sid'], function(err, session) {
if(!err && session && session.auth && session.auth.loggedIn ) {
self.setHandshakeValue( null,
'userId',
session.auth.userId,
handshake );
}
});
}
然后在模型中保存记录之前,您可以:
model._author = shished.getHandshakeValue( socket, 'userId' );
