如何在使用 Amplify 创建的 AWS lambda 函数上使用 chrome-aws-lambda

Question

我正在尝试使用 Amplify 在 AWS 中创建此 lambda 函数，但是当我尝试启动 chromium 时，lambda 函数没有 return 任何值，并且该函数最终会计时：

"errorMessage": "2020-12-09T02:56:56.210Z 57402f8e-9fb2-4341-837d-bdf2ee6e9262 Task timed out after 25.57 seconds" 我按照@James Shapiro 的建议添加了层，现在我得到了一个 URL return 用于铬，但它仍然没有启动它：

这是我的功能：

const chromium = require('chrome-aws-lambda');

exports.handler = async (event, context) => {

    const pageToScreenshot = "https://www.google.com"

    console.log('page:', pageToScreenshot);

    if (!pageToScreenshot) return {
        statusCode: 400,
        body: JSON.stringify({ message: 'Page URL not defined' })
    }

    console.log('launch:');
    console.log('chromium.args:', chromium.args);
    console.log('chromium.defaultViewport:', chromium.defaultViewport);
    console.log('chromium.headless:', chromium.headless);

    const executablePath = await chromium.executablePath;

    const browser = await chromium.puppeteer.launch({
        args: chromium.args,
        defaultViewport: chromium.defaultViewport,
        executablePath,
        headless: chromium.headless,
    });
    console.log('page:');

    const page = await browser.newPage();
    console.log('goto:');

    await page.goto(pageToScreenshot, { waitUntil: 'networkidle2' });
    console.log('screenshot:');

    const screenshot = await page.screenshot({ encoding: 'binary' });
    console.log('close:');

    await browser.close();
    console.log('response:');

    return {
        statusCode: 200,
        body: JSON.stringify({
            message: `Complete screenshot of ${pageToScreenshot}`,
            buffer: screenshot
        })
    }

}

这是依赖项：

Answer 1

您是否尝试过安装 chrome-aws-lambda 层，然后将其添加到您的函数中？请参阅“AWS Lambda 层”部分中的说明 here。

Answer 2

我不得不增加 lambda 函数的内存和超时，但是，如果没有 James Shapiro 的帮助，我不认为它会起作用，谢谢。
