[英]Need help digesting JSON blob returned using express-handlebars node.js
我现在开始使用node.js,并正在完成一个可ping Accuweather API并返回JSON数据blob的教程。
我已经知道了...但是展示片让我反感:
index.js
const express = require('express')
const rp = require('request-promise')
const exphbs = require('express-handlebars')
const path = require('path')
const app = express()
app.engine('.hbs', exphbs({
defaultLayout: 'main',
extname: '.hbs',
layoutsDir: path.join(__dirname, 'views/layouts')
}))
app.set('view engine', '.hbs')
app.set('views', path.join(__dirname, 'views'))
app.get('/:city', (req, res) => {
rp({
uri: 'http://apidev.accuweather.com/locations/v1/search',
qs: {
q: req.params.city,
apiKey: 'hoArfRosT1215'
// Use your accuweather API key here
},
json: true
})
.then((data) => {
console.log(data)
res.render('home', data)
})
.catch((err) => {
console.log(err)
res.render('error')
})
})
app.listen(3000)
home.hbs
<h2>Success!</h2>
<h2>{{data}}</h2>`
error.hbs
<h2>Error<h2>
home.hbs
<html>
<head>
<title>Express handlebars</title>
</head>
<body>
{{{body}}}
</body>
</html>
我已经搜索过Google,还没有真正找到好的解决方案。 我研究了车把的辅助功能……但实际上并没有提出任何建议。
我将如何开始显示来自Accuweather API的一些“数据”块?
仅供参考,这是我从console.logging回来的JSON博客

好的,您有:
res.render('home', data)
我认为应该是:
res.render("home", {data:data})
至于你的HTML
{{#each data}}
<div>
Name: {{this.LocalizedName}}
Rank: {{this.Rank}}
</div>
{{/each}}
