How can I intercept network requests using Puppeteer?

You can intercept network requests in Puppeteer by using the page.setRequestInterception(true) method. This allows you to listen to requests and modify them if needed.

Can you show me a code example for that?

Sure! Here's a simple example:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.setRequestInterception(true);

  page.on('request', request => {
    if (request.url().includes('example.com')) {
      request.abort(); // Block the request
    } else {
      request.continue(); // Continue with the request
    }
  });

  await page.goto('https://yourwebsite.com');
  await browser.close();
})();

What types of requests can I intercept?

You can intercept various types of requests, including GET, POST, and even WebSocket requests. You can also modify headers, change request bodies, or block requests entirely.

Is it possible to log the intercepted requests?

Yes, you can log intercepted requests by adding a logging statement inside the page.on('request', ...) event handler. For example, you can log the request URL and method.
