如何将 Google Docs Viewer 与 puppeteer 一起使用？

Question

我想通过运行在 Node.js 中的 puppeteer 通过 Google Docs Viewer 预览文档。 该 URL 在浏览器中运行良好：
https://docs.google.com/viewer?url=https%3A%2F%2Fdocs.npmjs.com%2Fimages%2Fnpm.svg&embedded=true

但是在 puppeteer 中抛出错误：

(async () => {          
        const browser = await puppeteer.launch();
        const page = await browser.newPage();           
        page.on('response', res => {
            res.text().then(text => {
                console.log('response:', {
                    url: res.url(),
                    status: res.status(),
                    res_headers: res.headers(),
                    req_headers: res.request().headers(),
                    text: text
                });
            });
        });

        await page.setBypassCSP(true);
        await page.goto(url, {waitUntil: 'networkidle0'});
        let content = await page.content();            
        await browser.close();

        return content;
    })();

当我比较 puppeter 和浏览器之间的 cookie 和标头时，标头“origin”、“x-origin”、“x-referrer”是相同的，但“x-chrome-connected”和“x-client” -日期”丢失。
cookie“NID”存在。

仔细查看 Google 的回复：

{"errors": [{"domain": "global", "reason": "required","message": "需要登录"}]}

{"errors": [{"domain": "global","re​​ason": "forbidden","message": "Forbidden"}]}

看来puppeteer Chromium 需要用Google 登录才能使用PDF 查看器功能。
