我是靠谱客的博主可爱帅哥，最近开发中收集的这篇文章主要介绍利用HTTP登录QQ群流程，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

/**
* QQ群登录流程
* 1. 登录表单页是一个iframe，直接取得iframe地址即可
*    http://ui.ptlogin2.qq.com/cgi-bin/login?appid=3000801&s_url=http%3A%2F%2Fqun.qq.com%2Fair%2F&f_url=loginerroralert&lang=2052&bgcolor=ffffff&style=1&low_login=1&link_target=blank&target=top&hide_title_bar=1&dummy=1
* 2. 登录页需要两个JS文件
*    http://imgcache.qq.com/ptlogin/js/comm.js
*    http://imgcache.qq.com/ptlogin/js/str_cn.js
*    及以下JS代码:
*    <pre>
   <script language="javascript">
    //映射模板文件中的文字,第一列为字符串ID, 第二列为模板文件中的标签ID
    var g_labelMap = new Array([STR_UINTIP, "u"],
            [STR_UIN, "label_uin"],
            [STR_PWD, "label_pwd"],
            [STR_VCODE, "label_vcode"],
            [STR_VCODE_TIP, "label_vcode_tip"],
            [STR_CHANGE_VCODE, "changeimg_link"],
            [STR_REMEMBER_PWD, "label_remember_pwd"],
            [STR_FORGET_PWD, "label_forget_pwd"],
            [STR_LOGIN, "login_button"],
            [STR_SWITCH_QLOGIN, "label_switch_qlogin"],
            [STR_LOGIN_TITLE, "label_login_title"],
            [STR_QLOGIN_INTRO, "label_qlogin_intro"],
            [STR_QLOGINING, "label_qlogining"],
            [STR_QLOGIN_HELP, "label_qlogin_help"],
            [STR_SWITCH_NORMAL, "label_switch_normal"],
            [STR_QLOGIN, "loginbtn"],
            [STR_1_DAY, "label_1_day"],
            [STR_1_WEEK, "label_1_week"],
            [STR_1_MONTH, "label_1_month"],
            [STR_HALF_YEAR, "label_half_year"],
            [STR_1_YEAR, "label_1_year"],
            [STR_QLOGIN_SELECT, "btn_qlogin_select"],
            [STR_QLOGIN_VER, "label_qlogin_ver"],
            [STR_QLOGIN_SELECT_TIP, "qlogin_select_tip"],
            [STR_NEW_REG, "label_newreg"]
            );
    document.domain="qq.com";
   </script>
*    </pre>
* 3. 在登录时，js方法的调用链如下：
*    1) ptui_onLogin(loginform) (由于没有parent，直接进catch段)
*    2) ptui_checkValidate(A)
*    3) preprocess(B) （这个方法用验证码和密码作了一个md5作为发送的密码）
*    <pre>
    function preprocess(A)
    {
    var B="";
    B+=A.verifycode.value;
    B=B.toUpperCase();
    A.p.value=md5(md5_3(A.p.value)+B);
    return true
    }
*    </pre>
* 4. 登录后，有一个跳转(这个url为群首页的url)
*    top.location.href='http://qun.qq.com/air/';
* 5. 取群首页后，发现里面没有群数据
*    用FireBug在Firefox下查看HTML，发现
*    <div id="container" class="module clear index">
*    ...... 群信息
*    </div>
*    但是查看源代码时：为空
*    <div id="container" class="module hide clear"></div>
*    原因是：在加载这个界面后，利用jQuery发送了ajax请求来加载数据,页面中有这样的代码：
*    <pre>
   <script type="text/javascript">
   document.domain = "qq.com";
   jL.script({mark: "jquery", uri: "/god/m/js/jquery.zh-cn.js?_=90168", depend: true});
   jL.script({mark: "jquery-plugins", uri: "/god/m/js/jquery/plugins.zh-cn.js?_=90168", depend: true});
   jL.script({mark: "frame", uri: "/god/m/js/frame.zh-cn.js?_=90168", depend: true, onload: function(p) {
       if ( $.browser.msie && "6.0" == $.browser.version ) {
           document.execCommand("BackgroundImageCache", false, true);
       }
       G.run(p);
   }, params: {
       request: location.href,
       domain: "qun.qq.com", server: "172.27.9.160", client: "218.247.140.212",

       },
       group: {

     permission: "2",

     }
    }
   }});
   </script>
*    </pre>
*    利用HttpWatch跟踪后，得到群的JSON数据地址为:
*    http://qun.qq.com/air/group/mine?w=a&_=0.4386851283768331
*    可以取到群的基本信息，如果再取好友，需要到通讯录页
* 6. 取好友
*    url形式为：http://qun.qq.com/air/2447222/addr/index/type/1/p/1?w=n&_=0.4386851283768331;
*    其中2447222为群号,addr/index/type/1/p/1中最后一个数字1为页号
*    因此要取所有好友必须访问所有的分页url(递归过程)
*    http://qun.qq.com/air/2447222/addr/index/type/1/p/1
*    http://qun.qq.com/air/2447222/addr/index/type/1/p/2
*    http://qun.qq.com/air/2447222/addr/index/type/1/p/3
*    http://qun.qq.com/air/2447222/addr/index/type/1/p/4 等等
*    步骤:
*    (1)取第一页取出好友
*    (2)取第一页的所有分页链接（注意去重）
*    (3)访问其他页链接并取出好友（如果其他页链接已访问过了，不再访问）
