Javascript Expressjs没有'；t销毁会话

我有一个主干视图，它向服务器发送Ajax调用以删除会话

在服务器上触发以下事件：

app.delete('/session', function(req, res) {
    if (req.session) {
        req.session.destroy(function() {
            res.clearCookie('connect.sid', { path: '/' });
            res.send('removed session', 200);
        });
    } else {
        res.send('no session assigned', 500);
    }
});

奇怪的是，我可以多次按下注销按钮而不会得到HTTP 500错误代码。铬还告诉我饼干仍然存在

出什么事了

问候

编辑：

我发现这不是直接的会话问题，而是cookie问题。 我将res.clearCookie添加到路由中。不幸的是，行为（cookie、会话保持活动）没有改变

EDIT2： 我现在给res.clearCookie一些参数=>res.clearCookie（'connect.sid'，{path:'/'}）； 现在至少浏览器中的cookie不见了。但会议似乎仍然可以进行。 或者至少我可以调用注销路由，我希望req.session应该为false

EDIT3: 我现在从redis中删除了所有会话，并重新启动了所有内容（redis、节点、浏览器）。

然后我再次登录并注销。到目前为止，这是有效的，但是当我用F5重新链接页面时，我得到了一个新的会话。为什么？

为了集中所有评论，我写了一个答案：

因为express总是为客户端创建会话和cookie，所以我们必须采取不同的方法，而不仅仅是检查是否存在会话

此部件处理登录

app.post('/session', function(req, res) {
    User.findOne({ username: req.body.username })
        .select('salt') // my mongoose schema doesn't fetches salt
        .select('password') // and password by default
        .exec(function(err, user) {
            if (err || user === null) throw err; // awful error handling here
            // mongoose schema methods which checks if the sent credentials
            // are equal to the hashed password (allows callback)
            user.hasEqualPassword(req.body.password, function(hasEqualPassword) {
                if (hasEqualPassword) {
                    // if the password matches we do this:
                    req.session.authenticated = true; // flag the session, all logged-in check now check if authenticated is true (this is required for the secured-area-check-middleware)
                    req.session.user = user; // this is optionally. I have done this because I want to have the user credentials available
                    // another benefit of storing the user instance in the session is
                    // that we can gain from the speed of redis. If the user logs out we would have to save the user instance in the session (didn't tried this)
                    res.send(200); // sent the client that everything gone ok
                } else {
                    res.send("wrong password", 500); // tells the client that the password was wrong (on production sys you want to hide what gone wronge)
                }
            });
        });
});

这是登录部分，请转到注销：

app.delete('/session', function(req, res) {
    // here is our security check
    // if you use a isAuthenticated-middleware you could make this shorter
    if (req.session.authenticated) {
        // this destroys the current session (not really necessary because you get a new one
        req.session.destroy(function() {
            // if you don't want destroy the whole session, because you anyway get a new one you also could just change the flags and remove the private informations
            // req.session.user.save(callback(err, user)) // didn't checked this
            //delete req.session.user;  // remove credentials
            //req.session.authenticated = false; // set flag
            //res.clearCookie('connect.sid', { path: '/' }); // see comments above                res.send('removed session', 200); // tell the client everything went well
        });
    } else {
        res.send('cant remove public session', 500); // public sessions don't containt sensible information so we leave them
    }
});

希望这有助于

如果您执行

delete req.session，会发生什么这不会影响会话，至少不会影响下一个请求，因为您只是在本地删除变量，而不是redis键。req.session.destroy也会删除此项。但是查看更新您不必清除cookie，connect将在不存在cookie的情况下为您提供一个新会话，也许这就是您所感知的同一会话？@kyogron只是一个简单的标志，如
authenticated:true
