Question

尝试通过在Nodejs中使用 req.session.destroy（）销毁会话来执行注销操作，但它无法正常工作。

Nodejs代码：

router.get('/logout', function(req, res) {
  req.session.destroy();
  console.log(session.email);
  res.redirect('/signup');
});

我从我的html文件调用/ logout api。

HTML代码： -

<div class="container-fluid">
        <header class="row top text-center">
            <div class="col-md-2 righttopnav" >
                <a href="index" style="font-size:25px;">Auto<b>SecT</b></a>
            </div>
            <div class="col-md-10 topnav" id="myTopnav">
                <%if(session.email){%>
                <a href="/logout">Logout</a>
                <% } else { %>
                <a href="/signup">Signup / Login</a>
                <% } %>
                <a href="#career">Career</a>
                <a href="#clients">Clients</a>
                <a href="#services">Services</a>
            </div>
        </header>

        <section class="content">   
            <div class="row text-center">
                <div class="col-md-12 " >
                    <p class="p1"><%-session.email%>Scan your Website or APP with just a <b>click!</b></p>
                </div>
            </div>
        </section>

        <div class="row text-center" style="padding-top:5%;">
            <div class="col-md-4">
                <i class="fa fa-globe fa-5x" aria-hidden="true" style="color:#c2c2a3"></i>
                <br>
                <input class="url" type="url"  placeholder="Enter your url" style="border-radius: 20px ">
            </div>  
            <div class="col-md-4">
                <p class="p">OR</p>
            </div>
            <div class="col-md-4">
                <i class="fa fa-file-o fa-5x" aria-hidden="true" style="color:#c2c2a3; padding-bottom: 4% "></i>
                <br>
                <label class="btn btn-primary btn-sm  btn-file upload">
                <i class="fa fa-upload fa-2x" aria-hidden="true"></i>
                <input type="file" style="display: none;">
                </label>
            </div>
        </div>
        <div class="row">
            <div class="col-md-12">
                <div class="col-md-12 text-center" style="padding-top: 5%; margin-bottom: 1%; border-radius: 20%;">
                <input type="submit" id="button" class="btn btn-success btn-md" value="Scan">
            </div>
            </div>
        </div>
</div>

/ logout将我重定向到所需的页面，但会话不会被破坏。

Answer 1

请在会话销毁后重定向。您必须在回调中移动代码以进行重定向。

Answer 2

尝试销毁会话并注销：

SET DEFAULT CURRENT_TIMESTAMP

Answer 3

这对我有用。

.get('/logout', function (req, res) {
    req.logout();
    req.session = null; 
    res.redirect('/back/to/login');
});

Answer 4

此解决方案适用于我：

req.session.destroy(function () {
    req.logout();
    res.redirect('/');              
});

Answer 5

我做了两件事，使它奏效了。首先，我在会话选项中将未设置为 destroy 。其次，删除会话，如下所示

router.get('/logout', function(req, res) {
        delete req.session;
        res.redirect('/signup');
    });

req.session.destroy（）在Nodejs中不起作用
