**前言**

本文的重要部分：

1、抓包获取QQ空间或者邮箱登陆地址，分析参数，用户名，密码，验证码，gtk，随即数。

2、获取每次登陆需要的验证码

3、用户名，密码，验证码加密得到登陆密码

4、Http模拟登陆拿cookie

本文实验的思路也可换另一种方式，抓包获取登陆的js,用代码操作js来计算密码 ，gtk等实现登陆。

**抓包**

1、我们来访问qq空间的地址http://i.qq.com/，打开网站，我们可以看到登陆的对话框，首先我们输入一个错误的账号和密码，抓起提交的地址。![SouthEast][]

2、输入用户名和密码之后我们用抓包工具看到有2个后台请求的地址，如下图

![SouthEast 1][]![SouthEast 2][]

我们可以根据返回的代码可以看出第二个图的地址是QQ登陆后台get请求的地址，所以我们实现登陆就是像这个地址提交数据。第一张图则是空间登陆每次返回的验证码产生的地址，通过多次输入正确用户名密码，第一张图地址返回类似ptui\_checkVC('0','!JWE','\\x00\\x00\\x00\\x00\\x46\\x86\\xd2\\x36');代码，其中括号内参数与登陆请求地址中verifycode=!JWE每次相同，这个便是登陆的验证码，登陆地址则返回类似ptuiCB('0','0','http://qzs.qq.com/qzone/v5/loginsucc.html?para=izone','0','登录成功！', 'xxx');返回此代码则说明登陆成功。

通过抓包我们提取出来的2个地址：

1、验证码获取地址（输入用户名时返回）：

http://check.ptlogin2.qq.com/check?regmaster=&uin=\{0\}&appid=549000912&js\_ver=10038&js\_type=1&login\_sig=46Flu6g0o2A1hcewVAPUpItgSNJncoqujR4vudgX8ZRnruuCSOzMGcbd3CnQhw0y&u1=http%3A%2F%2Fqzs.qq.com%2Fqzone%2Fv5%2Floginsucc.html%3Fpara%3Dizone&r=\{1\}

参数0：QQ账号，参数1：随即数

说明：一般情况下是不会产生手动输入验证码的情况下，若是QQ号码不存在或者错误，此时会出现图片验证码，我们可以用一个处理一下显示在imge中手动输入。

2、登陆提交地址：

http://ptlogin2.qq.com/login?u=\{0\}&p=\{1\}&verifycode=\{2\}&aid=549000912&u1=http%3A%2F%2Fqzs.qq.com%2Fqzone%2Fv5%2Floginsucc.html%3Fpara%3Dizone&h=1&ptredirect=0&ptlang=2052&from\_ui=1&dumy=&low\_login\_enable=0&regmaster=&fp=loginerroralert&action=11-52-1375668422981&mibao\_css=&t=1&g=1&js\_ver=10038&js\_type=1&login\_sig=46Flu6g0o2A1hcewVAPUpItgSNJncoqujR4vudgX8ZRnruuCSOzMGcbd3CnQhw0y

参数0：QQ号码，参数1：加密以后的密码，参数2：返回的验证码

本人文字功底实在太差，说不太清楚，抓包需要我多次试验，多次分析，才可取得正确的地址。登陆的最重要目的是获取请求页面的cookie。

**代码部分**

1、http请求帮助代码

1     public class HttpHelper
     2     {
     3         /// <summary>

     5         /// </summary>
     6         /// <param name="url"></param>
     7         /// <param name="cookieContainer"></param>
     8         /// <returns></returns>
     9         public static Stream GetStream(string url, CookieContainer cookieContainer)
    10         {
    11             HttpWebRequest httpWebRequest = null;
    12             HttpWebResponse httpWebResponse = null;
    13 
    14             try
    15             {
    16                 httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
    17                 httpWebRequest.CookieContainer = cookieContainer;
    18                 httpWebRequest.ContentType = contentType;
    19                 httpWebRequest.Referer = referer;
    20                 httpWebRequest.Accept = accept;
    21                 httpWebRequest.UserAgent = userAgent;
    22                 httpWebRequest.Method = "GET";
    23                 httpWebRequest.ServicePoint.ConnectionLimit = int.MaxValue;
    24 
    25                 httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    26                 Stream responseStream = httpWebResponse.GetResponseStream();
    27 
    28                 return responseStream;
    29             }
    30             catch (Exception)
    31             {
    32                 return null;
    33             }
    34 
    35         }
    36 
    37         /// <summary>
    38         /// 获取HTML
    39         /// </summary>
    40         /// <param name="url"></param>
    41         /// <param name="cookieContainer"></param>
    42         /// <returns></returns>
    43         public static string GetHtml(string url, CookieContainer cookieContainer)
    44         {
    45             Thread.Sleep(1000);
    46             HttpWebRequest httpWebRequest = null;
    47             HttpWebResponse httpWebResponse = null;
    48             try
    49             {
    50                 httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
    51                 httpWebRequest.CookieContainer = cookieContainer;
    52                 httpWebRequest.ContentType = contentType;
    53                 httpWebRequest.Referer = referer;
    54                 httpWebRequest.Accept = accept;
    55                 httpWebRequest.UserAgent = userAgent;
    56                 httpWebRequest.Method = "GET";
    57                 httpWebRequest.ServicePoint.ConnectionLimit = int.MaxValue;
    58 
    59                 httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    60                 Stream responseStream = httpWebResponse.GetResponseStream();
    61                 StreamReader streamReader = new StreamReader(responseStream, Encoding.UTF8);
    62                 string html = streamReader.ReadToEnd();
    63 
    64                 streamReader.Close();
    65                 responseStream.Close();
    66 
    67                 httpWebRequest.Abort();
    68                 httpWebResponse.Close();
    69 
    70                 return html;
    71             }
    72             catch (Exception)
    73             {
    74                 return string.Empty;
    75             }
    76 
    77         }
    78     }

2、获取验证码

//取验证码
            public static string GetVerfiyCode(string qqnum,CookieContainer cookie)
            {
                Random rand = new Random();
                double r = rand.NextDouble();
                string checkcodeurl = string.Format(@"http://check.ptlogin2.qq.com/check?uin={0}&appid=1006102&r={1}", qqnum, r);
                Stream stream = HttpHelper.GetStream(checkcodeurl, cookie);
                StreamReader streamReader = new StreamReader(stream, Encoding.UTF8);
                return streamReader.ReadToEnd();
            }
            //取图片验证码,可将验证码直接输出在image中
            public static Stream GetVerfycodeImage(CookieContainer cookie, string qqnum)
            {
                Random rand = new Random();
                double r = rand.NextDouble();
                string codeimageurl = string.Format("http://captcha.qq.com/getimage?aid=1006102&r={0}&uin={1}", r, qqnum);
                return HttpHelper.GetStream(codeimageurl, cookie);
            }

通过GetVerfiyCode()的返回 值判断，是否需要手动输入验证码

//得验证吗
                if (retString.Contains("ptui_checkVC('0','"))
                {
         
    　　　　　　　　　//不需要手动输入
                    this.txtverfiycode.Text = retString.Replace("ptui_checkVC('0','", "").Replace("'", "").Replace(")", "").Replace(";", "").Substring(0, 4);
                }
                else if (retString.Contains("ptui_checkVC('1',"))
                {
         
    　　　　　　　　//需要手动输入，将验证码输出在image中
                    this.vefycodpicbox.Image = Image.FromStream(GetVerfycodeImage(retString, this.txtUseraccount.Text));
                }

3、计算密码，密码的计算方法可以通过js计算，或者直接使用如下c\#版的，总的来说腾讯的密码加密比较麻烦，需要QQ号码，密码，验证码三个参数，有兴趣的可自己研究下。

代码如下：

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][]

1 public static class PasswordHelper
     2     {
     3         /// <summary>
     4         /// 根据QQ号码和验证码加密密码
     5         /// </summary>
     6         /// <param name="qqNum">QQ号码</param>
     7         /// <param name="password">QQ密码</param>
     8         /// <param name="verifycode">验证码</param>
     9         /// <returns>密码密文</returns>
    10         public static string GetPassword(string qqNum, string password, string verifycode)
    11         {
    12             //uin为QQ号码转换为16位的16进制
    13             int qq;
    14             int.TryParse(qqNum, out qq);
    15 
    16             qqNum = qq.ToString("x");
    17             qqNum = qqNum.PadLeft(16, '0');
    18 
    19             String P = hexchar2bin(md5(password));
    20             String U = md5(P + hexchar2bin(qqNum)).ToUpper();
    21             String V = md5(U + verifycode.ToUpper()).ToUpper();
    22             return V;
    23         }
    24 
    25         public static string md5(string input)
    26         {
    27             byte[] buffer = MD5.Create().ComputeHash(Encoding.GetEncoding("ISO-8859-1").GetBytes(input));
    28             return binl2hex(buffer);
    29         }
    30 
    31         public static string binl2hex(byte[] buffer)
    32         {
    33             StringBuilder builder = new StringBuilder();
    34             for (int i = 0; i < buffer.Length; i++)
    35             {
    36                 builder.Append(buffer[i].ToString("x2"));
    37             }
    38             return builder.ToString();
    39         }
    40 
    41         public static string hexchar2bin(string passWord)
    42         {
    43             StringBuilder builder = new StringBuilder();
    44             for (int i = 0; i < passWord.Length; i = i + 2)
    45             {
    46                 builder.Append(Convert.ToChar(Convert.ToInt32(passWord.Substring(i, 2), 16)));
    47             }
    48             return builder.ToString();
    49         }
    50     }

到此为止，登陆需要的参数已经全了，下面就是实现登陆拿cookie。

4、登陆的方法与获取验证码一样

//登录方法
            public static bool IsLogin(string qqnum,string code,string passwords,CookieContainer cookie)
            {
                string password = PasswordHelper.GetPassword(qqnum, passwords, code);
                string loginUrlstring = @"http://ptlogin2.qq.com/login?u=" + qqnum + "&p=" + password + "&verifycode=" + code + "&aid=1006102&u1=http%3A%2F%2Fid.qq.com%2Findex.html&h=1&ptredirect=1&ptlang=2052&from_ui=1&dumy=&fp=loginerroralert&action=8-29-82478035&mibao_css=&t=1&g=1";
                Stream stream = HttpHelper.GetStream(loginUrlstring, cookie);
                StreamReader streamReader = new StreamReader(stream, Encoding.UTF8);
                string retString = streamReader.ReadToEnd();//        retString    "ptuiCB('0','0','http://id.qq.com/index.html','1','登录成功！', 'xxx');\r\n"    string
                return retString.Contains("ptuiCB('0',") ? true : false;
            }

我们可以直接调用此方法验证是否登陆成功，同时将cookie保存在一个全局变量中供以后使用。

到此为止，QQ用http模拟登陆已经成功，完成了获取群列表的第一步。下面一篇就到获取群列表，群成员。

临时写的代码，时间仓促，比较杂乱，有什么出错的地方欢迎指出。若资料有用，帮忙顶一下。
