How can I use Puppeteer for advanced request interception?

You can use Puppeteer's page.setRequestInterception(true) method to intercept requests. This allows you to modify or block requests before they are sent.

Can you give me an example of intercepting a specific URL?

Sure! You can listen for the 'request' event and check the URL. Here's a sample code:

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

What if I want to modify the request instead of blocking it?

You can modify the request by using request.continue() with options. For example:

page.on('request', request => {
  if (request.url() === 'https://example.com/api/data') {
    request.continue({
      method: 'POST',
      postData: JSON.stringify({ key: 'value' }),
      headers: { 'Content-Type': 'application/json' }
    });
  } else {
    request.continue();
  }
});
