网上有很多通过分析pc版本的qq协议来卖qq群发软件或者qq机器人的，想起珊瑚虫的下场就知道触犯了腾讯的利益的下场，大家要注意，做个遵纪守法的攻城狮。

下面是步骤截图：

1.登录http://qun.qzone.qq.com/的网站。

2.打开firebug，获取到连接g_tk的值，如下图：

http://qun.qzone.qq.com/cgi-bin/get_group_list?groupcount=4&count=4&callbackFun=_GetGroupPortal&uin=1758317551&g_tk=2002785566&ua=Mozilla%2F5.0%20(Windows%20NT%206.1%3B%20WOW64%3B%20rv%3A25.0)%20Gecko%2F20100101%20Firefox%2F25.0

3.修改var g_tk=2002785566;的值，然后复制代码到firebug的console中

function ajax_request(url,callback,args){
	//declare the variable at the top, even though it will be null at first
	var req = null;
	//figure out what kind of support we have for the XMLHttpRequest object
	if (window.XMLHttpRequest){
		 //modern browsers
		 req = new XMLHttpRequest();   
	} else {
		//good ol‘ lousy IE
		req = new ActiveXObject("Microsoft.XMLHTTP");
	};

	//setup the readystatechange listener
	req.onreadystatechange = function(){
		//right now we only care about a successful and complete response            
		if (req.readyState === 4 && req.status === 200){
			//inject the returned HTML into the DOM
			if(callback){
				callback(req.responseText,args);
			}
		};
	};

	//open the XMLHttpRequest connection
	req.open("GET",url,true);

	//send the XMLHttpRequest request (nothing has actually been sent until this very line)
	req.send(false);  //false为同步请求              
};

var uin=1758317551;
var g_tk=2002785566;
get_groups();

function get_groups(){
	var url="http://qun.qzone.qq.com/cgi-bin/get_group_list?uin="+uin+"&ua=Mozilla%2F5.0%20(Windows%20NT%206.1%3B%20WOW64%3B%20rv%3A24.0)%20Gecko%2F20100101%20Firefox%2F24.0&random=0.029393406423685486&g_tk="+g_tk;
	ajax_request(url,callback_parse_groups);
}

function callback_parse_groups(response){
	var groups=[];
	var re = /groupid":(.*?),"groupname":"(.*?)"}/ig;
	var arr;
	while ((arr = re.exec(response)) != null){
		var id=arr[1];
		var name=arr[2];
	    var group={};
		group.id=id;
		group.name=name;
		groups.push(group);
		var groupid=id;
		var id=group.id;
		var name=group.name;
		get_group_members(id);
    }
}

function get_group_members(group){
	var url="http://qun.qzone.qq.com/cgi-bin/get_group_member?uin="+uin+"&groupid="+group+"&random=0.7269802233668716&g_tk="+g_tk;
	ajax_request(url,callback_parse_group_members,group);
}

function callback_parse_group_members(response,groupid){
	var re = /nick":"(.*?)","uin":(.*?)}/ig;
	var arr;
	var result="";
	var groupmembers=[];
	while ((arr = re.exec(response)) != null){
		var name=arr[1];
		var id=arr[2];
		var groupmember={};
		groupmember.id=id;
		groupmember.name=name;
		groupmember.groupid=groupid;
		console.info(name+" "+id);
    }	
}

4.点击运行即可输出所有获取到的群信息和群成员

利用这种方式可以很方便的处理需要登录的网站的信息，包括https的同理。
