Question

我有req.flash（）设置，并且每当我注销时都希望它显示一条消息，但是我收到一条错误消息，而不是来自我的欢迎页面（我重定向到的页面，错误：消息不是功能）。我不明白的是我的请求访问了views / message.ejs IS ，我什至还可以console.log（message）。

Message.ejs

<div id="messages">
<% Object.keys(messages).forEach(function (type) { %>
  <% messages[type].forEach(function (message) { %>
    <%= message %>
  <% }) %>
<% }) %>
</div>

登出路线

app.get('/logout', function(req, res){
    req.logout();
    req.flash('success', 'You have been logged out.');
    res.redirect('/login');
});

Express Messages中间件

app.use(require('connect-flash')());
app.use(function (req, res, next) {
  res.locals.messages = require('express-messages')(req, res);
  next();
});
