如何从Greasemonkey脚本拦截XMLHttpRequests？

// ==UserScript==
// @name         Intercept XMLHttpRequests
// @namespace    http://tampermonkey.net/
// @version      1.0
// @description  Intercept and log XMLHttpRequests
// @author       Your Name
// @match        http(s)://*/*
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    const OriginalXMLHttpRequest = window.XMLHttpRequest;

    window.XMLHttpRequest = function() {
        const xhr = new OriginalXMLHttpRequest();

        xhr.addEventListener('readystatechange', function() {
            if (xhr.readyState === 4) {
                console.log('Intercepted XMLHttpRequest:', xhr.responseURL, xhr.responseText);
            }
        });

        return xhr;
    };
})();
