How to intercept a web request

Question

Is there something like Chromium\'s chrome.webRequest for Safari extensions? I went through their documentation here. The closest thing I could find was Safari

Answer 1

We solved this problem by using "xmlhttprequest" overriding.

This is our content.js . We injected content.js as start script

    $(document).ready(function() {

     var myScriptTag = document.createElement('script');
     myScriptTag.src = safari.extension.baseURI + 'js/injectedToPage.js';
     document.body.appendChild(myScriptTag);     

    });    

injected code is: (injectedToPage.js)

XMLHttpRequest.prototype.reallySend = XMLHttpRequest.prototype.send;
XMLHttpRequest.prototype.send = function (body) { 

        console.log("--req.body:---");
        console.log(body);

    this.reallySend(body);

};
var req = new XMLHttpRequest();
req.open("GET", "any.html", true);
req.send(null);
