^^数据引用
这里是我尝试使用的一些数据。我制作了自己的 Api key 并在我的 route 使用它。
var router = require('express').Router();
const stockApi = 'YOUR_API_KEY';
router.get("/", function(req, res) {
var request = require('request');
request('https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=1min&apikey='+stockApi, function (error, response, body) {
var json = JSON.parse(body)
if (error) {
console.log(error)
} else {
console.log(json)
res.render("home/home", {data:json});
}
});
});
module.exports = router;
所以我解析了我的数据并将其作为“数据”传递到response.render中。
这是我有点困惑的地方。我正在尝试将“元数据”和“时间序列”打印到 ejs 模板中。但它会抛出一个错误，指出 forEach 不是一个函数。我对在 ejs 中使用 Json 数据有点陌生。这是我的模板，我只是想打印一条数据。
<body>
<%-include('../partials/navbar')%>
<div class="container">
<div class="row mt-4">
<div class="col">
<% data.forEach((stock) => { %>
<p><%=stock.Meta_Data %></p>
<%})%>
</div>
</div>
</div>
</body>
此外，当我发出请求时，我确实在控制台中看到了所有数据。我似乎无法打印我想要的对象。
最佳答案
您可以使用 for...in 执行类似的操作
