Question

嗨，我正在尝试将两个api请求合并到我的简单node.js网站上。我将它们都分开工作，但是我很难将两者结合在一起以在同一页面上工作。

  request(url2, function (err, response, body) {

    if(err){
      res.render('index', {news: null, error: 'Error, please try again',initials111:initials,test:potatoes});
    } else {
      let news = JSON.parse(body);

      if(news== undefined){
        res.render('index', {news: null, error: 'Error, please try again',initials111:initials,test:potatoes});
      } 

      else{
        let newsText = `${news.articles[0].title}`  ;
        res.render('index', {news: newsText, error: null,initials111:initials,test:potatoes});
      }
      }
    }

  );

  request(url, function (err, response, body) {

    if(err){
      res.render('index', {weather: null, error: 'Error, please try again',initials111:initials,test:potatoes});
    } else {
      let weather = JSON.parse(body);

      if(weather.main == undefined){
        res.render('index', {weather: null, error: 'Error, please try again',initials111:initials,test:potatoes});
      } else {
        if (rain == "0,rain"){
        let weatherText = `It's ${weather.main.temp} degrees celsius and with wind speeds of ${weather.wind.speed} mph in ${weather.name} ${weather.sys.country}! & ${weather.weather[0].description}`  ;
        res.render('index', {weather: weatherText, error: null,initials111:initials,test:potatoes});
      }
      else{
        let weatherText = `It's ${weather.main.temp} degrees celsius and with wind speeds of ${weather.wind.speed} mph in ${weather.name} ${weather.sys.country}!`  ;
        res.render('index', {weather: weatherText, error: null,initials111:initials,test:potatoes});
      }
      }
    }

  });

这是每个请求的代码的两个部分。如果需要，我可以附上网站的屏幕截图。如果我将它们都放在server.js文件中，则会收到很多错误。任何人都可以帮助/提供提示吗？

例如，当我将它们都粘贴到server.js并尝试访问网站时，我会收到此错误

ReferenceError: C:\NodeShit\weather-rough\views\index.ejs:42

    43|             <p><%= news %></p>

    44|           <% } %>

与多个基本的node.js请求混淆
