Question

我正在创建一个Node.JS网站，该网站需要创建POST端点才能为我的GET路由检索有效负载json数据，以便页面以保留的名和姓氏刷新。我该怎么做？我已将GET路由与POST端点json数据中所需的必要键/值包括在内。

const express = require('express');
const path = require('path');
const hbs = require('express-handlebars');

// Moment.js
var moment = require('moment');

// Init App
const app = express();

// Json File
const json = require("./data.json");

// Javascript Files
const welcomeTime = require('./public/javascript/welcomeTime');

// Load View Engine
app.engine('hbs', hbs({extname: 'hbs', defaultLayout: 'layout', 
layoutsDir: __dirname + '/views/layouts/'}));
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hbs');
app.use(express.static(__dirname+'/public'));

// GET Route
app.get('/', function(req, res){
     res.render('index', {
        title: 'NodePark',
        hotel: 'NodePark',

        // This woould be the json data I need from the payload
        firstName: json.payload.data.Source_FirstName,
        lastname: json.payload.data.Source_LastName,
        // end of data needed

        date: moment().format('ll'),
        time: moment().format('LT'),
        currentHour: welcomeTime.dayTime()
    });
 });

// POST Route
app.post('/hotel', function(req, res){
    res.redirect('/', {
    });
});

// Start Server
app.listen(5000, function(){
    console.log('Port 5000 LIVE.');
});

我已经包含了我正在使用的GET Route。

        <div id="logo-content">
            <div id="logo"></div>
        </div>
        <div id="welcome">
            <p>Good {{ currentHour }} {{ firstName }} {{ lastname }}. We hope your stay is comfortable & relaxing.</p>
        </div>
        </div>
        {{!-- <div id="time-side">
            <div id="time-content">
                <p> {{ date }} <br> {{ time }} </p>
            </div>
        </div> --}}
    </div> 
    {{!-- end of header --}}

    <div id="background">
        <img src="images/villaView.jpg" alt="villaView">
    </div>

    <div id="footer">

    </div>

我的目标是从POST端点检索数据，以将我的GET路由加载到我的网站上。

如何为需要json数据的GET路由的有效负载创建END Point
