js 拦截 xml请求

(function () {
  var originalSend = XMLHttpRequest.prototype.send;
  var originalOpen = XMLHttpRequest.prototype.open;

  XMLHttpRequest.prototype.open = function (method, url, async, user, password) {
    this._url = url; // 保存请求 URL，可能在后面用到
    return originalOpen.apply(this, arguments);
  };

  XMLHttpRequest.prototype.send = function (body) {
    this.addEventListener('load', function () {
      if (this.status == 200 && this._url.includes('.m3u8')) {
        // 在这里处理响应
        console.log('Response from:bb ', this._url, 'Status:', this.status);
      }
    });

    return originalSend.apply(this, arguments);
  };
})();
