Page.setRequestInterception() 方法

¥Page.setRequestInterception() method

激活请求拦截会启用 HTTPRequest.abort()、HTTPRequest.continue() 和 HTTPRequest.respond() 方法。这提供了修改页面发送的网络请求的能力。

¥Activating request interception enables HTTPRequest.abort(), HTTPRequest.continue() and HTTPRequest.respond() methods. This provides the capability to modify network requests that are made by a page.

一旦启用请求拦截，每个请求都会停止，除非继续、响应或中止；或者使用浏览器缓存完成。

¥Once request interception is enabled, every request will stall unless it's continued, responded or aborted; or completed using the browser cache.

有关详细信息，请参阅 请求拦截指南。

¥See the Request interception guide for more details.

中止所有图片请求的简单请求拦截器的示例：

¥An example of a naïve request interceptor that aborts all image requests:

import puppeteer from 'puppeteer';
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.setRequestInterception(true);
  page.on('request', interceptedRequest => {
    if (
      interceptedRequest.url().endsWith('.png') ||
      interceptedRequest.url().endsWith('.jpg')
    )
      interceptedRequest.abort();
    else interceptedRequest.continue();
  });
  await page.goto('https://example.com');
  await browser.close();
})();
