本人不太喜歡玩qq空間的，最近加了一個QQ好友，看頭像貌似一個大叔。錯了，是他加的我，他諮詢我微信自動打招呼不能使用的問題，本來上班就挺閒的，於是就和他聊開了。他問了我一句話，我頓時汗顏，感覺愧對自己這一兩年。什麼話呢？他說“最羨慕我們這羣在網絡上賺錢的了，你在網上轉了幾十萬了吧？”。由此我內疚啊，幾十萬角還是幾十萬元，勒個。這些都是引言，他給我啓發，我能否寫一個網頁工具，讓用戶導出他自己的QQ羣好友呢，導出QQ成員郵箱呢？現在電子商務那麼發達，有好些人都藉助QQ羣做營銷，QQ號碼的作用也就可想而知了 。上週五的 時候我找了個軟件，自動提取QQ羣成員的軟件，能是能用，罵了隔壁的要收費。不說這些了，言歸正傳。
首先我找到QQ空間的登錄界面i.qq.com,抓一下包 這裏是想嘗試找到他的登錄鏈接，以及上傳的參數信息。爲了調試簡便，直接找他的登錄表單，地址是：http://xui.ptlogin2.qq.com/cgi-bin/xlogin?proxy_url=http%3A//qzs.qq.com/qzone/v6/portal/proxy.html&daid=5&pt_qzone_sig=1&hide_title_bar=1&low_login=0&qlogin_auto_login=1&no_verifyimg=1&link_target=blank&appid=549000912&style=22&target=self&s_url=http%3A//qzs.qq.com/qzone/v5/loginsucc.html?para=izone&pt_qr_app=%E6%89%8B%E6%9C%BAQQ%E7%A9%BA%E9%97%B4&pt_qr_link=http%3A//z.qzone.com/download.html&self_regurl=http%3A//qzs.qq.com/qzone/v6/reg/index.html&pt_qr_help_link=http%3A//z.qzone.com/download.html，這麼長一串，看着頭都暈了吧，這個地址不用管它，是寫死的。
請求這個頁面，會返回一個重要的參數，查看這個頁面的源碼，裏面有個login_sig的玩意，登錄的簽名標識，這個參數在檢查登錄是否需要驗證碼的時候會用到
開啓網絡監聽可以發現，在輸入完QQ號碼的時候，也就是QQ號碼輸入框失去焦點的時候，瀏覽器會發一個請求到騰訊服務器，檢查此次登錄是否需要輸入驗證碼。請求地址：http://check.ptlogin2.qq.com/check?regmaster=&uin=qq號碼&appid=549000912&js_ver=10100&js_type=1&login_sig=-C312hp6B8CxoeIKpP*g2HaPLthAwHxTGa5u5WRgaDwrDi*3DrpjYwh38eh8-nyu&u1=http%3A%2F%2Fqzs.qq.com%2Fqzone%2Fv5%2Floginsucc.html%3Fpara%3Dizone&r=0.22668678383342922，login_sig是上面得到的安全登錄簽名標識，其它參數可以不變，這個請求會返回一個字符串，ptui_checkVC('0','!GGG','\x00\x00\x00\x00\x23\xe8\xf1\xd0','ffa99a5e8b464c05ab1666287089353996556b1c4964173e52ac0d76716f2d5676c8b41555aa551e5ad33146945d2041');
這裏有四個參數，第一個參數爲是否需要驗證碼，1是，0否。如果第一個參數是0,那麼第二個參數直接就是驗證碼，如果第,一個參數是1，第二個參數則是獲取驗證碼的密文，第三個參數不用管它，第四個參數爲登錄的時候需要的 pt_verifysession_v1參數，除了第三個參數外，這幾個都是很重要的參數。注意，如果此次登錄需要驗證碼，那麼第四個參數是空的，那麼登錄是需要的pt_verifysession_v1參數怎麼得到呢
如果登錄需要驗證碼，瀏覽器會發一個請求獲取驗證圖片，地址是:http://captcha.qq.com/getimage?uin=$qq&aid=549000912&cap_cd=$p2&0.7444603350013494 ,
這裏我們只需要注意一下cap_cd這個參數，這個參數是上面講的第二個參數。這個請求回返回一個cookies值，這個值是保持當前驗證碼和登錄一直的重要參數，抓包的時候查看cookies可以看到verifysession。
以上都是登錄前的參數收集，現在我們來看一下登錄地址：http://ptlogin2.qq.com/login?u=qq號&verifycode=驗證碼&pt_vcode_v1=0&pt_verifysession_v1=驗證碼返回的verifysession&p=加密的密碼&pt_rsa=0&u1=http%3A%2F%2Fqzs.qq.com%2Fqzone%2Fv5%2Floginsucc.html%3Fpara%3Dizone&ptredirect=0&h=1&t=1&g=1&from_ui=1&ptlang=2052&action=2-10-1416737142521&js_ver=10100&js_type=1&login_sig=安全登錄標識符&pt_uistyle=32&aid=549000912&daid=5&pt_qzone_sig=1&
經過之前的收集 ，我們發現這裏只有一個參數我們未知。那就是p參數，那麼是怎麼加密的呢，我們查看源碼，會發現這樣一個js文件
加密的算法都在裏面了，經過查看源碼，我們可以看到它的加密方式，先將密碼md5加密，再講加了密的密碼轉換爲二進制碼，然後再和QQ號首尾相連進行md5加密，結果在和驗證碼首尾相連md5加密，挺複雜的。加密獲取p參數 var p = $.Encryption.getEncryption(password,$.str.uin2hex(qq), verifycode);

最後總結一下php模擬登錄的幾個步驟：
1、訪問登錄頁面，獲取login_sig參數，php中通過stream_get_contents函數獲取網頁內容，通過preg_match正則匹配可獲得login_sig
2、檢查本次登錄是否需要驗證碼，獲取驗證碼，verifysession參數.
3、如果需要驗證碼，則獲取驗證碼圖片和返回的verifysession,
function _getVImg($url = "", $filename = "") {
$cookie_file = dirname(__FILE__).'/cookie.txt';
if(is_dir(basename($filename))) {
echo "The Dir was not exits";
Return false;
}
//去除URL連接上面可能的引號
$url = preg_replace( '/(?:^[\'"]+|[\'"\/]+$)/', '', $url );
$hander = curl_init();
$fp = fopen($filename,'wb');
curl_setopt($hander,CURLOPT_URL,$url);
curl_setopt($hander,CURLOPT_FILE,$fp);
curl_setopt($hander,CURLOPT_HEADER,0);
//curl_setopt($hander,CURLOPT_FOLLOWLOCATION,1);
curl_setopt($hander, CURLOPT_COOKIEJAR, $cookie_file); //存儲cookies
//curl_setopt($hander,CURLOPT_RETURNTRANSFER,false);//以數據流的方式返回數據,當爲false是直接顯示出來
curl_setopt($hander,CURLOPT_TIMEOUT,60);
$content=curl_exec($hander);
curl_close($hander);
$fp2 = fopen($cookie_file,'r');
$ses='';
while(!feof($fp2))
{
$ses.=fgets($fp2);
}
$nodle='verifysession ';
$sw= strstr($ses,$nodle);
$result = trim(str_replace($nodle,'',$sw));
fclose($fp);
fclose($fp2);
Return $result;
}
4、對密碼進行加密，得到需要的p參數
var p = $.Encryption.getEncryption(password,$.str.uin2hex(qq), verifycode);
5、構建登錄地址：http://ptlogin2.qq.com/login?u=qq號&verifycode=驗證碼&pt_vcode_v1=0&pt_verifysession_v1=驗證碼返回的verifysession&p=加密的密碼&pt_rsa=0&u1=http%3A%2F%2Fqzs.qq.com%2Fqzone%2Fv5%2Floginsucc.html%3Fpara%3Dizone&ptredirect=0&h=1&t=1&g=1&from_ui=1&ptlang=2052&action=2-10-1416737142521&js_ver=10100&js_type=1&login_sig=安全登錄標識符&pt_uistyle=32&aid=549000912&daid=5&pt_qzone_sig=1& 把參數放進去就行了。接下來你知道該怎麼做了吧
大功告成！
