Question

这是我的代码

 const express =require('express');
    const bodyParser=require('body-parser');
    const User=require('./models/User');
    const mongoose=require('mongoose');
    const cookieParser = require('cookie-parser');
    const  session = require('express-session');
    const MemcachedStore = require("connect-memcached")(session);
    const app=express();


    app.use(cookieParser());
        var MemoryStore =session.MemoryStore;
        app.use(session({
            name : 'app.sid',
            secret: "1234567890QWERTY",
            resave: true,
            store: new MemoryStore(),
            saveUninitialized: true
    }));



    mongoose.connect("mongodb://localhost:27017/alpha")
    .then(()=>{ 
      console.log("Connected to database")
    })
    .catch((err)=>{
      console.log("Error occureed");
      throw err;

    })
    app.use(bodyParser.json());
    app.use(bodyParser.urlencoded({extended:false}));
    app.use((req,res,next)=>{
      res.setHeader('Access-Control-Allow-Origin','*');
      res.setHeader('Access-Control-Allow-Headers',
      'Origin,X-Requested-With,Content-Type,Accept');
      res.setHeader('Access-Control-Allow-Methods','GET,POST,PATCH,DELETE,OPTIONS');

      next();//calls the next one
      console.log("hello");
    });



    app.post('/api/post',(req,res)=>{

        req.session.name='kk';
        req.session.email=req.body.email;
        req.session.password=req.body.password;
        req.session.phonenumber=req.body.phonenumber;
        console.log(req.session.email);//this works
        res.json({
          message:'Data catched by server'
        });

    });

    app.get('/api/post',(req,res)=>{
      res.send("hello"+req.session.email);//this does'nt works
         console.log(req.session.email);
        });


    module.exports=app;

我正在通过body解析器保存请求参数值，并在get request中输出它们，但是它显示了未定义的数据，同时在浏览器或控制台中输出了数据，并记录了如何实现这一点？，我已经在有效的代码和无效的代码中进行了注释。

无法输出Express JS中存储在会话中的数据
