如何在puppeteer上截取下载请求并读取被截取的文件

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  // 在这里执行后续操作
})();

await page.setRequestInterception(true);

page.on('request', (request) => {
  if (request.resourceType() === 'document') {
    request.continue();
  } else if (request.resourceType() === 'xhr' && request.url().endsWith('.pdf')) {
    // 拦截下载请求
    request.abort();
    // 读取被截取的文件
    const fileData = request.postData();
    console.log(fileData);
  } else {
    request.continue();
  }
});

await page.goto('https://example.com');
await page.click('#download-button');
