[c#] 网络协议模拟之QQ微博分享接口应用

      QQ微博在营销领域越来越受青睐了，这里面集成了很多非常有用的接口，像是邮件分享、空间分享、QQ分享、微信分享等。这相对于传统的直接模拟协议，登录邮箱等方式进行邮件发送甚至更有效。所有这些都没什么技术难度，所以实现起来是很简单的。如果在开发过程中遇到了些困难的话，可能是多线程的把握吧！

     在这样一些营销类项目之中，绝大多数都设计了多账号切换操作，这使得整个架构控制起来异常繁琐。对于多线程功底稍差的人来说，加上UI设计的搭配，简直就是地狱般的折磨。项目实战开发最需要的就是经验的积累，平时练习的时候就得多为下一次开发做技术上的准备，否则一旦开始就会显得很吃力耗时。

    

上图只是我一个项目里的一张截图，我们要说的功能大致就是上面图中所表现出来的。但是这里，只做一个功能实现描述，不作项目完整实现。

步骤：

1.基础功能的类准备

1.处理xml的xmlHelper，2.处理Http模拟的HttpHelper 3.处理QQ登录验证密码MD5加密的QQMd5 4.其他一些Util功能实现类

所有这些类我会稍后放在文章附件里。

2.创建Account用户资料类[登录]

下面的这个类我只是给各位一个例子，可以展开看一下，但是还是要自己依据自己情况具体分析。

public class Account
   {
       #region 属性
       /// <summary>
       /// 帐号登录的顺序号码
       /// </summary>
       public int ID { get; set; }
       /// <summary>
       /// QQ帐号
       /// </summary>
       public string Uin { get; set; }
       public List<string> Froms { get; set; }
       public string Mail { get; set; }
       /// <summary>
       /// 昵称
       /// </summary>
       public string Nick { get; set; }
       /// <summary>
       /// 我的首页
       /// </summary>
       public string MyPage { get; set; }
       /// <summary>
       /// QQ未加密的密码
       /// </summary>
       public string Password { get; set; }
       /// <summary>

       /// </summary>
       public string P { get; set; }
       /// <summary>
       /// QQ微博的Cookie容器
       /// </summary>
       public CookieContainer WeiboCookieContainer { get; set; }
       /// <summary>
       /// QQ微博的Cookie字符
       /// </summary>
       public string WeiboCookieString { get; set; }
       /// <summary>
       /// QQ微博对应的Sid
       /// </summary>
       public string Sid { get; set; }
       /// <summary>
       /// 目前帐号的状态
       /// </summary>
       public Status CurrentStatus { get; set; }
       /// <summary>
       /// 帐号类型
       /// </summary>
       public AccountStyle AccountStyle { get; set; }
       /// <summary>
       /// 是否需要验证码
       /// </summary>
       public bool NeedVerify { get; set; }
       /// <summary>
       /// 验证码图片
       /// </summary>
       public Image VerifyImage { get; set; }
       /// <summary>
       /// 验证码字符串
       /// </summary>
       public string VerifyCode { get; set; }
       
       #endregion
       #region 构造函数
       public Account()
       {
           Init();
       }
       public Account(string uin, string password)
       {
           this.Uin = uin;
           this.Password = password;
           Init();
       }
       #endregion
       #region 私有函数
       private void Init()
       {
           this.WeiboCookieContainer = new CookieContainer();
           this.CurrentStatus = Status.Unlogin;
           this.AccountStyle = AccountStyle.Unknow;
       }
       #endregion
}
}

上面的那些都不是关键，我们要做的第一步还是完成“判断验证码>输入验证码（如果有的话）>登录”，除了要我完成Http模拟请求之外还要从返回的结果中提取有用的信息。

 #region 登录过程
       /// <summary>
       /// 判断登录微博是否需要验证码
       /// </summary>
       /// <returns></returns>
       public bool CheckVerify_Weibo(ref string vctype)
       {
           string url = "", html;
           url = string.Format("http://check.ptlogin2.qq.com/check?uin={0}@qq.com&appid=46000101&ptlang=2052&r={1}", this.Uin,new Random().NextDouble());
           html = HttpHelper.GetHtml(url, this.WeiboCookieContainer);
           if (string.IsNullOrEmpty(html)) return false;
           string pattern = @"ptui_checkVC\('(?'need'[^']*)','(?'vctype'[^']*)','[^']*'\);";
           string need = html.Match(pattern, "need");
           vctype = html.Match(pattern, "vctype");
           if (need == "1")
           {
               this.CurrentStatus = Status.NeedVerify;
              this.VerifyImage= this.GetImage();
               return true;
           }
           else
           {
               this.CurrentStatus = Status.Unlogin;
               this.VerifyCode = vctype;
               return false;
           }
         
       }
       /// <summary>
       /// 获取显示验证码
       /// </summary>
       /// <returns></returns>
       public Image GetImage()
       {
         string url = string.Format("http://captcha.qq.com/getimage?aid=46000101&r=0.38706237439032276&uin={0}@qq.com", this.Uin);
           Stream stream = HttpHelper.GetStream(url, this.WeiboCookieContainer);
           Image image = Image.FromStream(stream);
           return image;
       }
       /// <summary>
       /// 登录
       /// </summary>
       /// <returns></returns>
       public string Login()
       {
           string uin,password,verifyCode;
           uin = this.Uin;
           password = this.Password;
           verifyCode = this.VerifyCode;
           string html="";
        if (string.IsNullOrEmpty(uin) || string.IsNullOrEmpty(password))
               throw new Exception("没有添加帐号，或帐号的密码为空");
           if (string.IsNullOrEmpty(verifyCode))
               throw new Exception("验证码为空，无法继续登录");
           this.P = QQMd5.Encrypt(uin,password,verifyCode);
           string url = string.Format("http://ptlogin2.qq.com/login?ptlang=2052&u={0}@qq.com&p={1}&verifycode={2}&low_login_enable=1&low_login_hour=720&css=http://imgcache.qq.com/ptcss/b4/wb/46000101/login1.css&aid=46000101&mibao_css=m_weibo&u1=http%3A%2F%2Ft.qq.com&ptredirect=1&h=1&from_ui=1&dumy=&fp=loginerroralert&action=7-9-1381063&g=1&t=1&dummy=",
                                     uin, this.P, verifyCode);
           html = HttpHelper.GetHtml(url, this.WeiboCookieContainer);
           if (html.Contains("您输入的验证码不正确，请重新输入"))
               throw new Exception(string.Format("验证码输入不正确"));
           else if (html.Contains("您输入的帐号或密码不正确，请重新输入"))
               throw new Exception(string.Format("帐号或密码不正确"));
           else if (html.Contains("登录成功"))
           {
               html = string.Format("登录成功");
               this.CurrentStatus = Status.Login;
             
           }
         
           return html;
         }

由于本人不太喜欢用已经做好的轮子去用Json处理类(比如Newtonsoft.net)，所以一般处理都是用的正则表达式，各位也可以自己用JsonObejct类去处理，不用跟我一样用正则这种笨方法。
3.获取必要信息[提取微博数据]

 public string GetInfo()
       {string html="";
           try
           {
               string url = "http://t.qq.com";
               html = HttpHelper.GetHtml(url, this.WeiboCookieContainer);
               string pattern = @"href=""(?'mypage'[^""]*)""><u>首页";
               string mypage = html.Match(pattern, "mypage");
               this.MyPage = mypage;
               if (string.IsNullOrEmpty(mypage)) throw new Exception("获取微博话题列表失败");
               pattern = @"boss=""btnWideSideMyNick"">(?'nick'[^<]*)</a>";
               string nick = html.Match(pattern, "nick");
               if (html.Contains("立即开通")) this.CurrentStatus = Status.NotRegist;
               this.Nick = nick;
               html = "成功获取微博话题列表";
           }
           catch(Exception e)
           {
               html = e.Message;
           }
           return html;
       }
       public List<FriendInfo> GetQQFriendList()
       {
           string account = ""; string r = "1351620387406";
           account = this.MyPage.ToLower().Replace("http://t.qq.com/", "");
           string url = string.Format("http://api.t.qq.com/share/qqList.php?account={0}&r={1}&apiType=8&apiHost=http://api.t.qq.com&_r={1}",
                                                account,r);
           HttpHelper.Referer = this.MyPage;
           HttpHelper.ExtendHeadData = string.Format("rf:{0}", this.MyPage);
           string html = HttpHelper.GetHtml(url, this.WeiboCookieContainer);
          
           HttpHelper.Referer = "";
           HttpHelper.ExtendHeadData = "";
           Regex regex = new Regex(@"(""sortId"":(?'sordId'[^""]+),)*""name"":""(?'name'[^""]+)"",(""groupId"":(?'groupId'[^,]+),)*(""member"":(?'member'\[[^\]]*\]))*", RegexOptions.IgnoreCase);
           MatchCollection matches = regex.Matches(html);
           List<FriendInfo> list = new List<FriendInfo>();
           for (int i = 0; i < matches.Count; i++)
           {
               
               string sortId = matches[i].Groups["sortId"].Value;
               string name = matches[i].Groups["name"].Value;
               string groupId = matches[i].Groups["groupId"].Value;
               string member = matches[i].Groups["member"].Value;
               Regex memberRegex = new Regex(@"""qq"":""(?'qq'[^""]*)"",""pic"":null,""nick"":""(?'nick'[^""]*)""", RegexOptions.IgnoreCase);
               MatchCollection memberMatches = memberRegex.Matches(member);
               for (int j = 0; j < memberMatches.Count; j++)
               {
                   string qq = memberMatches[j].Groups["qq"].Value;
                   string nick = memberMatches[j].Groups["nick"].Value;
                   FriendInfo friendInfo = new FriendInfo();
                   friendInfo.Uin = qq;
                  friendInfo.Name = WebQQ.Converter.Unicode_js_1(name);
                 
                   friendInfo.Nick = WebQQ.Converter.Unicode_js_1(nick);
                   if (friendInfo.Name == "最近联系人") continue;
                   friendInfo.SortId = sortId;
                   friendInfo.GroupId = groupId;
                   friendInfo.QQ = Uin;
                    list.Add(friendInfo);

               }


           }
           return list;
       }

上面这一步不一定是必须的，但是没有这一步，我们后面所要实现的功能就会很困难。包括发送分享给QQ，这一步，因为要发送的QQ好友的号码不是真正的号码，而是一个系统随机生成的好友序列号的MD5加密字段。因此，我们也无法用于分享QQ给陌生人号码。

4.分享

          string html = HttpHelper.GetHtml(url, postString, this.WeiboCookieContainer);
           HttpHelper.Referer = "";
           return html;
       }

           HttpHelper.ExtendHeadData = string.Format("rf:{0}", this.MyPage);
           HttpHelper.Referer = "http://api.t.qq.com/proxy.html";

           string html = HttpHelper.GetHtml(url,postString, this.WeiboCookieContainer);

       }
      #endregion
