I'm aware that chrome.webRequest.onBeforeRequest
allows a request to be intercepted, analyzed and blocked, but it only allows access to the request headers, and not the request body (as far as i know).
Sample use case: think intercepting form values.
It seems there is a API change proposal here suggesting exactly this.
Is there another way this could be accomplished?
Thanks.
This functionality has been added to the API now, see the documentation.
In order to access the body you need to do the following:
chrome.webRequest.onBeforeRequest.addListener(
function(details)
{
console.log(details.requestBody);
},
{urls: ["https://myurlhere.com/*"]},
['requestBody']
);
