我试图拦截所有类型的通话。我甚至在stackoverflow上找到了一些关于它的指南和问题。遗憾的是，所有这些都是关于拦截XHR调用（使用XMLHTTPrequest或/和ActiveXObject）。我需要做的是拦截所有类型的调用（即使浏览器开发人员工具指示为不同类型的调用[不是XHR ]，例如：文档，脚本或其他）并保存一些信息localStorage的。 我无法使用JQuery
我的代码：
var xml_type;
// branch for native XMLHttpRequest object
if (window.XMLHttpRequest && !(window.ActiveXObject==undefined)) {
xml_type = 'XMLHttpRequest';
// branch for IE/Windows ActiveX version
} else if (window.ActiveXObject) {
try {
x = new ActiveXObject('Msxml2.XMLHTTP');
xml_type = 'Msxml2.XMLHTTP';
} catch (e) {
x = new ActiveXObject('Microsoft.XMLHTTP');
xml_type = 'Microsoft.XMLHTTP';
}
}
var ActualActiveXObject = window.ActiveXObject;
var ActiveXObject;
if (xml_type == 'XMLHttpRequest') {
(function (open) {
if (s_ajaxListener === undefined) {
var s_ajaxListener = new Object();
s_ajaxListener.tempOpen = XMLHttpRequest.prototype.open;
s_ajaxListener.tempSend = XMLHttpRequest.prototype.send;
s_ajaxListener.callback = function () {
// this.method :the ajax method used
// this.url :the url of the requested script (including query string, if any) (urlencoded)
// this.data :the data sent, if any ex: foo=bar&a=b (urlencoded)
};
XMLHttpRequest.prototype.open = function (a, b) {
if (!a) a = '';
if (!b) b = '';
s_ajaxListener.tempOpen.apply(this, arguments);
s_ajaxListener.method = a;
s_ajaxListener.url = b;
var xhr = this;
xhr.openTime= new Date().getTime();
setRequest(xhr.openTime, a, b);
if (a.toLowerCase() == 'get') {
s_ajaxListener.data = b.split('?');
s_ajaxListener.data = s_ajaxListener.data[1];
}
};
XMLHttpRequest.prototype.send = function (a, b) {
if (!a) a = '';
if (!b) b = '';
s_ajaxListener.tempSend.apply(this, arguments);
if (s_ajaxListener.method.toLowerCase() == 'post') s_ajaxListener.data = a;
var xhr = this;
var interval = setInterval(function () {
if (xhr.readyState === 4) {
setResponse(xhr, a);
clearInterval(interval);
}
}, 200);
s_ajaxListener.callback();
};
}
})(XMLHttpRequest.prototype.open);
} else {
ActiveXObject = function (progid) {
console.log("progid ", progid);
var ax = new ActualActiveXObject(progid);
if (progid.toLowerCase() == "microsoft.xmlhttp") {
var o = {
_ax: ax,
_status: "fake",
responseText: "",
responseXml: null,
readyState: 0,
dataType: 'plain',
status: 0,
statusText: 0,
onReadyStateChange: null,
onreadystatechange: null
};
o._onReadyStateChange = function () {
var self = o;
return function () {
self.readyState = self._ax.readyState;
if (self.readyState == 4) {
self.responseText = self._ax.responseText;
self.responseXml = self._ax.responseXml;
self.status = self._ax.status;
self.statusText = self._ax.statusText;
setResponse(self, self.responseText);
}
if (self.onReadyStateChange) {
self.onReadyStateChange();
}
if (self.onreadystatechange) {
self.onreadystatechange();
}
}
}();
o.open = function (bstrMethod, bstrUrl, varAsync, bstrUser, bstrPassword) {
this._ax.onReadyStateChange = this._onReadyStateChange;
this._ax.onreadystatechange = this._onReadyStateChange;
o.openTime = new Date().getTime();
setRequest(o, bstrMethod, bstrUrl);
return this._ax.open(bstrMethod, bstrUrl, varAsync, bstrUser, bstrPassword);
};
o.send = function (varBody) {
return this._ax.send(varBody);
};
o.abort = function () {
return this._ax.abort();
}
o.setRequestHeader = function (k, v) {
return this._ax.setRequestHeader(k, v)
}
o.setrequestheader = function (k, v) {
return this._ax.setRequestHeader(k, v)
}
o.getResponseHeader = function (k) {
return this._ax.getResponseHeader(k)
}
o.getresponseheader = function (k) {
return this._ax.getResponseHeader(k)
}
} else if (progid.toLowerCase() == "msxml2.xmlhttp") {
var o = {
_ax: ax,
_status: "fake",
responseText: "",
responseXml: null,
readyState: 0,
dataType: 'plain',
status: 0,
statusText: 0,
onReadyStateChange: null,
onreadystatechange: null
};
o._onReadyStateChange = function () {
var self = o;
return function () {
self.readyState = self._ax.readyState;
if (self.readyState == 4) {
self.responseText = self._ax.responseText;
self.responseXml = self._ax.responseXml;
self.status = self._ax.status;
self.statusText = self._ax.statusText;
}
if (self.onReadyStateChange) {
self.onReadyStateChange();
}
if (self.onreadystatechange) {
self.onreadystatechange();
}
}
}();
o.open = function (bstrMethod, bstrUrl, varAsync, bstrUser, bstrPassword) {
this._ax.onReadyStateChange = this._onReadyStateChange;
this._ax.onreadystatechange = this._onReadyStateChange;
alert('Intercept');
return this._ax.open(bstrMethod, bstrUrl, varAsync, bstrUser, bstrPassword);
};
o.send = function (varBody) {
return this._ax.send(varBody);
};
o.abort = function () {
return this._ax.abort();
}
o.setRequestHeader = function (k, v) {
return this._ax.setRequestHeader(k, v)
}
o.setrequestheader = function (k, v) {
return this._ax.setRequestHeader(k, v)
}
o.getResponseHeader = function (k) {
return this._ax.getResponseHeader(k)
}
o.getresponseheader = function (k) {
return this._ax.getResponseHeader(k)
}
} else {
var o = ax;
}
return o;
}
}
setRequest和setResponse只是在localStorage中保存数据的函数。
此代码拦截所有XHR请求但不拦截其他请求，我需要拦截所有请求。
