我可以从谷歌搜索中获取 JSON LD 数据吗？

Question

我希望使用 Alexa 的 AWS Lambda 函数，并且想知道是否可以提取填充 First Avenue Calendar 站点的 JSON LD 事件数据？

https://www.google.com/search?q=first+avenue+calendar&oq=first+avenue+calendar&aqs=chrome.0.69i59j69i60l3j0l2.3727j0j7&sourceid=chrome&ie=UTF-8

我不确定这是否可行或从哪里开始，有什么想法吗？

Answer 1

抓取此类数据虽然不可靠，但微不足道。应该在 chrome 开发者工具中运行几行 JS 代码：

这里有一些东西可以帮助你开始（每次谷歌更新他们的搜索时，类名 _Kjf 和 Kjg 都需要更新，因此不可靠）：

let obj = [];
for (const n of document.getElementsByClassName('_Kjf')) {
    const date = n.getElementsByClassName('_Kjg')[0].innerText;
    const title = n.getElementsByClassName('title')[0].innerText;
    const time = n.getElementsByClassName('_Jjg')[0].innerText;
    obj.push({date, time, title});
}
console.log(JSON.stringify(obj, null, 2));

结果：
