javascript - 从 reddit 获取高分辨率图像

Question

我正在尝试按新近度从 Reddit 子版 block 中获取高分辨率图像。我可以提取缩略图，但不知道如何提取真正的高分辨率图像。

这是我的代码:

fetch('https://www.reddit.com/r/cats.json')
  .then(res => res.json())
  .then(res => res.data.children)
  .then(res => res.map(post => ({
    author: post.data.author,
    link: post.data.url,
    img: post.data.thumbnail,
    title: post.data.title
  })))
  .then(res => res.map(render))
  .then(res => console.log(res))

const app = document.querySelector('#app');

const render = post => {
  const node = document.createElement('div');
  node.innerHTML = `
      <a href="${post.link}">
        <img src="${post.img}"/>
      </a>`;
  app.appendChild(node);
}

这是我的fiddle

有什么想法吗？

Answer 1

看起来您需要交换 href 和 img src

fetch('https://www.reddit.com/r/cats.json')
.then(res => res.json())
.then(res => res.data.children)
.then(res => res.map(post => ({
  author: post.data.author,
  link: post.data.url,
  img: post.data.thumbnail,
  title: post.data.title
})))
.then(res => res.map(render))
.then(res => console.log(res))

const app = document.querySelector('#app');
const render = post => {
const node = document.createElement('div');
 node.innerHTML = `
  <a href="${post.img}">
    <img src="${post.link}"/>
  </a>`;
app.appendChild(node);
}
