QQ登陆篇

   前段时间想做个QQ的一个辅助工具，需要登陆QQ，从网上搜索了些资料，自己进行了实践和改造，可以成功登陆qq

如图：

 1、获取登陆验证码，如下http://ptlogin2.qq.com/check?uin={0}&appid=15000101，如果获取的验证码为！开头，就可以不用获取图片验证码，否则需要获取图片验证码，地址为：http://captcha.qq.com/getimage?aid=1003903&&uin={0}&vc_type={1}，vc_type为上次获取的验证码，注意:获取这些信息时，必须返回Cookie

 1         public static User getVerifyCodeImg(string qq)
 2         {
 3             HTTPModel hTTPModel = new HTTPModel(string.Format("http://ptlogin2.qq.com/check?uin={0}&appid=15000101", qq));
 4             WebHTTPUtil.sendHTTP(hTTPModel);
 5             CookieCollection cookie = hTTPModel.ReturnCookies;
 6             string value = WebHTTPUtil.GetValue(hTTPModel.ReturnHtml, "','", "'");
 7             Console.WriteLine("yzm:" + value);
 8             User user = new User();
 9             if (value.Contains("!"))
10             {
11                 user.VerifyCode = value;
12             }
13             else
14             {
15                 string imgUrl = string.Format("http://captcha.qq.com/getimage?aid=1003903&&uin={0}&vc_type={1}", qq, value);
16                 user.VerifyCodeUrl = imgUrl;
17             }
18             user.QQNum = qq;
19             user.Cookie = cookie;
20             return user;
21 
22         }

2、获取验证码图片，设置图片控件的image属性this.verifyImg.Image = WebHTTPUtil.byteArrayToImage(imgUrl, ref cookie);

 1         public static Image byteArrayToImage(string url, ref CookieCollection cookie)
 2         {
 3             Uri requestUri = new Uri(url);
 4             WebRequest webRequest = WebRequest.Create(requestUri);
 5             Image result;
 6             using (WebResponse response = webRequest.GetResponse())
 7             {
 8                 if (!string.IsNullOrEmpty(response.Headers[HttpResponseHeader.SetCookie]))
 9                 {
10                     CookieContainer cookieContainer = new CookieContainer();
11                     cookie = new CookieCollection();
12                     cookieContainer.SetCookies(webRequest.RequestUri, response.Headers[HttpResponseHeader.SetCookie]);
13                     cookie.Add(cookieContainer.GetCookies(webRequest.RequestUri));
14                 }
15                 using (Stream responseStream = response.GetResponseStream())
16                 {
17                     result = Image.FromStream(responseStream);
18                 }
19             }
20             return result;
21         }

3.对QQ密码和验证码进行散列，使用MD5

        public static string binl2hex(byte[] buffer)
        {
            StringBuilder stringBuilder = new StringBuilder();
            for (int i = 0; i < buffer.Length; i++)
            {
                stringBuilder.Append(buffer[i].ToString("x2"));
            }
            return stringBuilder.ToString();
        }
        public static string md5_3(string input)
        {
            MD5 mD = MD5.Create();
            byte[] buffer = mD.ComputeHash(Encoding.Default.GetBytes(input));
            buffer = mD.ComputeHash(buffer);
            buffer = mD.ComputeHash(buffer);
            return WebHTTPUtil.binl2hex(buffer);
        }
        public static string md5(string input)
        {
            byte[] buffer = MD5.Create().ComputeHash(Encoding.Default.GetBytes(input));
            return WebHTTPUtil.binl2hex(buffer);
        }        

View Code 
 1         public static User LoginQZone(string qq, string pwd, string verifyCode, CookieCollection cookie, User u)
 2         {
 3             //object password = WebHTTPUtil.GetPassword(pwd, verifyCode);
 4             System.Security.Cryptography.MD5 md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();
 5             string QQPwd = Md5(Md5_3(pwd) + verifyCode.ToUpper());
 6             string loginUrl = string.Format("http://ptlogin2.qq.com/login?u={0}&p={1}&verifycode={2}&aid=15000101&u1=http%3A%2F%2Fimgcache.qq.com%2Fqzone%2Fv5%2Floginsucc.html%3Fpara%3Dizone&h=1&ptredirect=1&ptlang=2052&from_ui=1&dumy=&fp=loginerroralert", qq, QQPwd, verifyCode);
 7             HTTPModel hTTPModel = new HTTPModel(loginUrl);
 8             hTTPModel.Encoding = Encoding.UTF8;
 9             hTTPModel.PostCookies = cookie;
10             WebHTTPUtil.sendHTTP(hTTPModel);
11             User result;
12             Console.WriteLine(QQPwd + "  " + verifyCode);
13             Console.WriteLine(loginUrl);
14             Console.WriteLine(hTTPModel.ReturnHtml);
15 }

当打印出如下，代表登陆成功

http://ptlogin2.qq.com/login?u=***&p=***&verifycode=!4CP&aid=15000101&u1=http%3A%2F%2Fimgcache.qq.com%2Fqzone%2Fv5%2Floginsucc.html%3Fpara%3Dizone&h=1&ptredirect=1&ptlang=2052&from_ui=1&dumy=&fp=loginerroralert
ptuiCB('0','0','http://imgcache.qq.com/qzone/v5/loginsucc.html?para=izone','1','登录成功！', 'heavy');

第一步QQ登陆完成
