我正在创建一个作业列表scraper，它会去几个作业站点，抓取作业，然后将它们聚合在一起。我想创建一个端点，如果我喜欢一份工作，我可以自动下载我自己的求职信，其中包含基于该工作的某些动态数据。目前，我已经从谷歌文档中获取了求职信的HTML，并从中创建了一个字符串。我设置了一个GET端点，该端点应该获取这个HTML字符串，并将其作为可下载的PDF发送给请求者。目前，PDF正在下载中，但该文档称"无法加载PDF文档"。如果能为解决这一问题提供任何帮助，我们将不胜感激。

您可以尝试使用puppeteer从html生成PDF文档。
下面的代码可以做到这一点，尽管我不得不去掉样式标签(可以在线添加，或者想办法让木偶师玩得很好(
const express = require('express');
const dotenv = require('dotenv');
const app = express();
dotenv.config();
async function generatePdf(html) {
const puppeteer = require("puppeteer");
const browser = await puppeteer.launch({
args: ['--no-sandbox'],
headless: true
});
const page = await browser.newPage();
await page.goto(`data:text/html,${html}`, {
waitUntil: 'networkidle0'
});
const options = {
format: 'A4',
margin: { top: "60px", bottom: "60px" },
printBackground: true,
}
const pdf = await page.pdf(options);
await browser.close();
return pdf;
}
