会话cookie使用Ajax和nodejs服务器不改 [英] Session cookies do not change using ajax and nodejs server

问题描述

我想一个异步请求后更改会话cookie，但不管是什么我想我一直失败。 我的要求如下：

I want to change a session cookie after an asynchronous request but no matter what I tried I keep failing. My request is as follows:

$.ajax({
    type: "POST",
    url: "/setStatus",
    data: { userId : _userId, token: _token, tokenSecret : _tokenSecret, service : service, loggedIn : _loggedIn, authorized : _authorized },
    xhrFields: { withCredentials: true },
    crossDomain: true
}).done(function(reply) { alert('finished'); });

在服务器上设置会话变量。

Setting the session variables on the server.

exports.setStatus = function(req, res)
{
    req.session.userId = req.body.userId;
    req.session.token = req.body.token;
    req.session.tokenSecret = req.body.tokenSecret;
    req.session.service = req.body.service;
    req.session.loggedIn = req.body.loggedIn;
    req.session.authorized = req.body.authorized;

    res.header('Access-Control-Allow-Credentials', 'true');
    res.writeHead(200);
};

在服务器上的设置如下所示：

The setting on the server are as follows:

app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.cookieParser());
app.use(express.bodyParser());
app.use(express.session({ secret: 'keyboard cat', store: new RedisStore({ host: 'localhost', port: 3000, client: dbcon })}));
app.use(express.methodOverride());
app.use(passport.initialize());
app.use(passport.session());
app.use(express.static(path.join(__dirname, 'public')));
app.use(app.router);

我忘了提及，在简单的要求如预期的会话cookie改变。 有任何想法吗？

I forgot to mention that on simple requests the session cookies change as expected. Any ideas?

推荐答案

您应该调用req.session.save（）的修改之后，如果你正在做它用AJAX。

You should call req.session.save() after the modifications if you are doing it with ajax.

exports.setStatus = function(req, res)
{
    req.session.userId = req.body.userId;
    req.session.token = req.body.token;
    req.session.tokenSecret = req.body.tokenSecret;
    req.session.service = req.body.service;
    req.session.loggedIn = req.body.loggedIn;
    req.session.authorized = req.body.authorized;
    req.session.save(); // This saves the modifications

    res.header('Access-Control-Allow-Credentials', 'true');
    res.writeHead(200);
};
