它本身已对xhr做过一次代理

window._ahrealxhr = window._ahrealxhr || XMLHttpRequest,
        XMLHttpRequest = function() {
            for (var attr in this.xhr = new window._ahrealxhr,
            this.xhr) {
                var type = "";
                try {
                    type = _typeof(this.xhr[attr])
                } catch (e) {}
                "function" === type ? this[attr] = hookfun(attr) : Object.defineProperty(this, attr, {
                    get: getFactory(attr),
                    set: setFactory(attr)
                })
            }
        }
