问题描述

我需要通过

授权Cookie

为了表达响应,我使用技术 JSONP 绕过谷歌的 CORS,但我不知道如何将 cookie 传递给响应。所以客户端浏览器可以获取该cookie。最终结果是带有 cookie 的直接 google drive 链接。目前只传递直接链接,但 cookie 为空。我不知道。

客户端html

<video id="video-player" controls></video>
<script>
  const videoPlayer = document.getElementById('video-player');

  (async () => {
    const response = await fetch('http://127.0.0.1:8080/video');

    videoPlayer.src = await response.text();
  })();
</script>

服务器

const express = require('express');
const htmlParser = require('node-html-parser');
const { parse }  = htmlParser;
const cors = require('cors');
const fetch = require('node-fetch');
const app = express();
const port = 8080;

app.get('/video', cors(), async (req, ress) => {    

    const response = await fetch('https://drive.google.com/uc?id=17OunL0rN- 
                                   7jrsNGjznQTqnB_z7xfsgKK&export=download', { redirect: 'manual' });

    const dom = parse(await response.text());

    const url = 'https://drive.google.com' + dom.querySelector('#uc-download-link')._attrs.href;

    const resCookie = await response.headers.get('set-cookie').split(';');

    const downloadCookie = resCookie[0];
    const nidCookie = resCookie[6].split(',')[1];

    const reqCookie = downloadCookie + ';' + nidCookie;

    let options = {
        headers: {
            cookie: reqCookie
        },
        redirect: 'manual'
    };

    const res = await fetch(url, options);

    const re = await fetch(await res.headers.get('location'), {redirect: 'manual'});

    const authCookie = await re.headers.get('set-cookie').split(';')[0];

    const r = await fetch(await re.headers.get('location'), { headers: { cookie: nidCookie }, redirect: 'manual' });

    const data = await fetch(await r.headers.get('location'), { headers: { cookie: authCookie}, redirect: 'manual'});

    ress.send(await r.headers.get('location'));
});

app.listen(port , () => {
    console.log(`Server is listening on ${port}`);
});

解决方案


您可以使用 res.cookie(name, value) 通过 express 设置 cookie。你可以在这里阅读更多关于它的信息。
