我正在尝试使用 heroku 服务器中的 puppeteer 将屏幕截图应用程序用于我的投资组合。

服务器.js

(async() => {
        const browser = await puppeteer.launch({
            args: ['--no-sandbox', '--disable-setuid-sandbox']
        });

        const page = await browser.newPage();

        await page.goto(urlToScreenshot,{timeout:60000});

        await page.waitFor(3000);


        await page.screenshot().then(function(buffer) {
            res.setHeader('Content-Disposition', 'attachment;filename="' + urlToScreenshot + '.png"');
            res.setHeader('Content-Type', 'image/png');
            res.send(buffer);
        });

        await browser.close();
    })();
