^^数据引用

这里有一些我想要使用的数据。我制作了自己的Api键并在我的路线中使用它。

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传递给response.render作为＆＃39;数据＆＃39;。

这是我有点困惑的地方。我正在尝试打印“元数据”＃39;和＆＃39;时间序列＆＃39;进入ejs模板。但它会抛出错误，因为每个都不是一个函数。我在ejs中使用Json数据有点新鲜。这是我的模板，我只是想打印一个数据。

 <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>

当我发出请求时，我确实看到了控制台中的所有数据。我似乎无法打印出我想要的物体。

您可以使用for...in

请安装Alpha Vantage Wrapper的npm软件包

1。npm install --save alpha_vantage_api_wrapper for NPM

const express = require('express');
const app =express();

var Alpha = require('alpha_vantage_api_wrapper').Alpha;                       //Alpha Wrapper
var alpha = new Alpha('demo');  
var stock_Dates = [];                                                         //Array Of Data      
var stock_opens = [];
var stock_highs = [];
var stock_lows = [];
var stock_closes = [];
var stock_volumes = [];

app.get('/', function(req,res){
    res.render('list', { query, stock_Dates, stock_opens, stock_highs, stock_lows, stock_closes, stock_volumes });
                                                                            //Injected in to views
});

app.post('/', function(req,res) {
        const query = req.body.stockName;
        alpha.stocks.intraday(query)                                        //Alpha Api-wrapper Function
            .then((data) => {
                const intraDay = (data['Time Series (5min)']);              

                for(var update in intraDay){
                    var stock_Date = update;
                    var stock_open = intraDay[update]['1. open'];           //Narrowing the endpoints for accessing the req Data
                    var stock_high = intraDay[update]['2. high'];
                    var stock_low = intraDay[update]['3. low'];
                    var stock_close = intraDay[update]['4. close'];
                    var stock_volume = intraDay[update]['5. volume'];
                    stock_Dates.push(stock_Date);                           //Pushing the Data into the Array of Data
                    stock_opens.push(stock_open);       
                    stock_highs.push(stock_high);
                    stock_lows.push(stock_low);
                    stock_closes.push(stock_close);
                    stock_volumes.push(stock_volume);
                }
                res.redirect('/');                                          //Redirects To the hamepage
            })
            .catch((err) => {
                // Handle the error
                console.log(err);                                           //Logs error if any
            });
        
});
