How to distinguish a web request from a regular page from a request from the extension itself from a Chrome/Opera extension?

Question

PHP

Intercepting a webRequest by calling chrome.webRequest.onBeforeSendHeaders.addListener()

Answer 1

If you do so - as written above

$str = "Њ®бЄў , Њ®бЄў , „¬Ёва®ўбЄЁ© Їа®Ґ§¤, 1Ѓ (¬. „¬Ёва®ўбЄ п)";
echo iconv("CP1251", "UTF-8", $str );

then you need to consider what exactly this file you have in what encoding? to prevent double decoding. Save the string to a separate file exactly with 1251 encoding, then read its contents using file_get_contents and only then do iconv.

Answer 2

Try this mb-convert-encoding

Answer 3

In the handler, get details.tabId, if it is -1 then the request was made not from the browser tab.

Pass an additional parameter in the request?
