如何在從 API 獲取數據時打印子文件夾數據

Question

我是 web 開發和學習如何使用 API 的新手。 我正在使用這個快速 API 並且只想打印默認的 url 而不是整個 json 文件。 請幫忙

這是來自快速 API 的正文文件

"Item":[18 items
0:{8 items
"name":"Top News"
"defaultname":"Top News"
"defaulturl":"http://timesofindia.indiatimes.com/feeds/newsdefaultfeeds.cms?feedtype=sjson"
"sectionurl":"http://timesofindia.indiatimes.com/feeds/feedurllist.cms?category=topnews"
"subsections":"no"
"template":"headlines"
"Icon":""
"ID":"Top-01"
}
1:{8 items
"name":"City"
"defaultname":"All Cities"
"defaulturl":"http://timesofindia.indiatimes.com/feeds/newsfeed/-2128932452.cms?feedtype=sjson"
"sectionurl":"http://timesofindia.indiatimes.com/feeds/feedurllist.cms?category=city"
"subsections":"yes"
"template":"news"
"Icon":""
"ID":"City-01"
}

這是我的腳本

async function fetchnews(){

  const fetchresult=fetch("https://devru-times-of-india.p.rapidapi.com/feeds/feedurllist.cms?catagory=city%252FItem%252Fdefaulturl", {
    "method": "GET",
    "headers": {
      "x-rapidapi-host": "devru-times-of-india.p.rapidapi.com",
      "x-rapidapi-key": "2406d619fbmsh3e12d4fa0d35484p1c63c9jsn0404e4a39e3b"
    }
  })
  response=await fetchresult;
  const data=await response.json();
  console.log(data); 

}
fetchnews();

這是控制台輸出（我只想打印 defaulturl）

Item: (18) […]
​​
0: Object { name: "Top News", defaultname: "Top News", defaulturl: "http://timesofindia.indiatimes.com/feeds/newsdefaultfeeds.cms?feedtype=sjson", … }
​​
1: Object { name: "City", defaultname: "All Cities", defaulturl: "http://timesofindia.indiatimes.com/feeds/newsfeed/-2128932452.cms?feedtype=sjson", … }
​​
2: Object { name: "India", defaultname: "India", defaulturl: "http://timesofindia.indiatimes.com/feeds/newsfeed/-2128936835.cms?feedtype=sjson", … }

您的 api 的響應是{'Item': [...]} 。 這意味着您應該在響應中迭代“項目”並從那里提取defaulturl 。

    async function fetchnews(){

      const fetchresult=fetch("https://devru-times-of-india.p.rapidapi.com/feeds/feedurllist.cms?catagory=city%252FItem%252Fdefaulturl", {
        "method": "GET",
        "headers": {
          "x-rapidapi-host": "devru-times-of-india.p.rapidapi.com",
          "x-rapidapi-key": "2406d619fbmsh3e12d4fa0d35484p1c63c9jsn0404e4a39e3b"
        }
      })
      response=await fetchresult;
      const data=await response.json();
      
      for(item of data.Item) {
        console.log(item.defaulturl);
      }
    }
    fetchnews();
