javascript - Catch and Modify XHR requests from Facebook with Chrome Extension

Question

Trying to catch and modify XHR requests from Facebook.com. The exact request URL is

https://www.facebook.com/ajax/composerx/attachment/link/scraper/?scrape_url={A URL GOES HERE}.

Is this possible with a chrome extension? Searched everywhere to no avail.

Answer 1

我相信你想要的是http://developer.chrome.com/extensions/webRequest.html#event-onCompleted

如果您想修改要发送的内容，那么我认为您想要的是注册 onBeforeRequest 处理程序。
