How can I determine if an HTTPRequest originates from an iframe's document while using Puppeteer?

I’m looking for guidance on how to identify if the current HTTP request is related to a document that has loaded within an iframe. Here’s a snippet of what I’m working on:

await page.setRequestInterception(true);
page.on('request', (request) => {
   if (request.isInterceptResolutionHandled()) {
      return;
   }
   // How can I check if the request originated from an iframe's document?
});
await page.goto('https://example.com/page-with-iframes');

I’ve attempted using the following code, but it hasn’t worked as expected:

let currentFrame = page.frames().find(f => f.url() === request.url());
if (currentFrame) {
   console.log('Found the iframe!');
}

However, this logic fails because the iframe’s URL hasn’t loaded yet.

You can use the request.frame() method to check if the request originates from an iframe. Here’s a revised snippet:

await page.setRequestInterception(true);
page.on('request', (request) => {
   if (request.isInterceptResolutionHandled()) return;
   const frame = request.frame();
   if (frame && frame.parentFrame()) {
       console.log('Request from an iframe!');
   }
   request.continue();
});

This checks if a request's frame has a parent, implying it’s from an iframe.

To determine if an HTTP request has originated from an iframe’s document using Puppeteer, you can indeed utilize the request.frame() method, as suggested. This method returns the frame associated with the request, and if the frame has a parent, it confirms the request is from an iframe.

Building on this approach, one thing to look out for is ensuring your requests are handled promptly without interference. Additionally, consider logging the frame's URL or checking its attributes, which can give more context about the iframe origin:

await page.setRequestInterception(true);
page.on('request', (request) => {
   if (request.isInterceptResolutionHandled()) return;
   const frame = request.frame();
   if (frame && frame.parentFrame()) {
       console.log('Request from an iframe:', frame.url());
       // Additional checks or actions here
   }
   request.continue();
});
await page.goto('https://example.com/page-with-iframes');

In this updated logic, frame.url() is used to log the URL associated with the iframe, which can help you trace or verify the origin more effectively. This change ensures that the identification of requests from iframes is both accurate and informative.

To efficiently determine if an HTTP request originated from an iframe's document using Puppeteer, the request.frame() method proves quite useful. This method gives you access to the frame associated with a request, and if this frame has a parent, it's an indication that the request came from an iframe.

await page.setRequestInterception(true);
page.on('request', (request) => {
   if (request.isInterceptResolutionHandled()) return;
   const frame = request.frame();
   if (frame && frame.parentFrame()) {
       console.log('Request from an iframe!');
   }
   request.continue();
});
await page.goto('https://example.com/page-with-iframes');

This streamlined check identifies requests from iframes by confirming the presence of a parent frame. This approach simplifies accurate detection and allows for any additional actions needed based on the request’s origin.

To check if an HTTP request is from an iframe in Puppeteer, use request.frame(). Here's how:

await page.setRequestInterception(true);
page.on('request', (request) => {
   if (request.isInterceptResolutionHandled()) return;
   const frame = request.frame();
   if (frame && frame.parentFrame()) {
       console.log('Request from an iframe!');
   }
   request.continue();
});
await page.goto('https://example.com/page-with-iframes');

This checks if the request's frame has a parent frame, indicating it's from an iframe.
