为什么我的回复看起来像这样？节点获取

Question

我是 Node JS 的新手，我正在尝试从此 URL 获取数据：https://www.tiktok.com/node/share/user/@test/

您无需登录任何内容即可查看数据，只需单击 link 即可看到我要访问的数据。但是，当我尝试使用 node-fetch 检索此数据以便我可以使用它时，我得到了一个奇怪的响应（或者，更好的说法是，我不知道这意味着什么哈哈）

}

这是我使用的代码。

const fetch = require('node-fetch')

fetch("https://www.tiktok.com/node/share/user/@test/")
.then(res => {
  console.log(res);
})

我看了整篇文章，不太明白这意味着什么。抱歉问了，但是是的

您正在查看的是 Response 对象，它表示整个 HTTP 响应。如果您只对 JSON 数据感兴趣，您可以使用 Response.json() 方法提取它：

const fetch = require("node-fetch");

// you'll get an "invalid json response body" error without this
const headers = { "User-Agent": "node-fetch" };

const response = fetch("https://www.tiktok.com/node/share/user/@test", {
  headers,
})
  // first, extract JSON data from `Response` object
  .then((res) => res.json())
  // then print JSON data that was parsed
  .then((data) => console.log(data));

Why does my response look like this? Node-Fetch

javascript

request

fetch

node.js

node-fetch
