问题描述

如何在所有车把页面中获取Express Session变量，现在我每次都渲染它，我希望它仅执行一次并从车把页面访问.

How to get the Express Session variable in all the handlebars pages, right now i have render it each time, i want it to be done once only and access in from the handlebar page.

index.js

app.post('/first',function(req,res){
var session = require('express-session');
req.session.fullname =Email;
res.render('first',
{Email:req.session.fullname,arrayofpromotions:arrayofpromotion,layout:false});

first.handlebars

first.handlebars

 <li><a href="#"> {{#if Email}} Welcome {{ Email }}{{/if}}</a></li>

当从/first url请求页面时，我可以读取会话变量(如已渲染的那样)，但不能从其他页面读取，我希望变量可用而不渲染它.这样我也可以从其他页面读取会话变量.

When the page is requested from /first url, i can read the session variable, as i have rendered it, but not from other pages, i want the variable available without rendering it. So that i can read the session variables from some other pages also.

就像我去/second一样，req.session.fullname也应该包含值.

Like if i go to /second also the req.session.fullname should contain value.

我阅读了关于stackoverflow的其他答案，但没有得到确切的解决方案.请帮忙.

I read some other answers on stackoverflow but i didnt get the exact solutions for it. Please help.

推荐答案

车把中的会话:

    // app.js
    app.use(session(options));
    app.use(function (req, res, next) {
        res.locals.session = req.session;
        next();
    });

在 handlebars 模板上使用

如下: {{session.SOMETHING_THAT_YOU_ASSIGNED}}
