【中文标题】如何在车把文件中打印“body”元素？【英文标题】：How to print the 'body' elements in the handlebars file? 【发布时间】：2019-11-05 22:13:59 【问题描述】：我是 Hnadlebars 的新手。我不知道如何打印我从服务器获取的“body”元素作为响应。如何在“.hbs”文件中打印正文元素。
var express=require('express');
const app=express();
var fs=require('fs');
var path=require('path');
const hbs=require('hbs');
var request=require('request');
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded( extended: false ));
app.use(bodyParser.json());
app.set('view engine','hbs');
app.get('/',function(req,res)
res.sendFile(path.join(__dirname + '/prac.html'));
);
app.post('/route',function(req,res)
request(
url:'https://api.railwayapi.com/v2/route/train/'+req.body.tnum+'/apikey/<my-apikey>/',json:true
,function(error,response,body)
if(error)throw error;
res.render('route',body);
);
);
app.listen(3000);<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title>My Route page</title>
</head>
<body>
<form action="/route" method="post">
Train Number:<input type="text" name="tnum" required><br>
<input type="submit" name="submit">
</form>
</body>
</html>这是回应

【问题讨论】：
这是产生的响应。 你要展示什么？ 【参考方案1】：这是syntax，你可以使用each来遍历数组
<div class="entry">
<h1>body.train.name</h1>
<div class="body">
#each body.train.days
<div>this.code</div>
/each
</div>
</div>
【讨论】：
如果它对你有用，请接受答案，谢谢@Rajat【参考方案2】：确保您传入res.render('route',body); 的主体是数据类型对象，如果不是，请先使用JSON.parse(body) 对其进行解析。您可以使用typeof body 检查数据类型。
然后在前端你直接拥有body的所有属性。只需直接使用response_code，而不是body.response_code。
要迭代几天使用：
#each train.days
<div>this.code - this.runs</div>
/each
