How to send ajax requests from extension?

Question

Google Chrome

I am writing an extension. I ran into difficulties, namely I can not use the window of the page. But I found a solution - to embed javascript into the page, but as I understand it - I need the ability to send AJAX requests as script extensions can. How can you inject a script into an extension and not lose the ability to make AJAX requests where necessary (of course ignoring Origin)?

Answer 1

Add the permissions field to the manifest.json extension and specify the addresses to which you want to send Ajax requests

"permissions": [
    "webRequest",
    "<all_urls>"
],
