[c#] 網絡協議模擬之QQ微博分享接口應用

      QQ微博在營銷領域越來越受青睞了，這里面集成了很多非常有用的接口，像是郵件分享、空間分享、QQ分享、微信分享等。這相對於傳統的直接模擬協議，登錄郵箱等方式進行郵件發送甚至更有效。所有這些都沒什么技術難度，所以實現起來是很簡單的。如果在開發過程中遇到了些困難的話，可能是多線程的把握吧！

     在這樣一些營銷類項目之中，絕大多數都設計了多賬號切換操作，這使得整個架構控制起來異常繁瑣。對於多線程功底稍差的人來說，加上UI設計的搭配，簡直就是地獄般的折磨。項目實戰開發最需要的就是經驗的積累，平時練習的時候就得多為下一次開發做技術上的准備，否則一旦開始就會顯得很吃力耗時。

    

上圖只是我一個項目里的一張截圖，我們要說的功能大致就是上面圖中所表現出來的。但是這里，只做一個功能實現描述，不作項目完整實現。

步驟：

1.基礎功能的類准備

1.處理xml的xmlHelper，2.處理Http模擬的HttpHelper 3.處理QQ登錄驗證密碼MD5加密的QQMd5 4.其他一些Util功能實現類

所有這些類我會稍后放在文章附件里。

2.創建Account用戶資料類[登錄]

下面的這個類我只是給各位一個例子，可以展開看一下，但是還是要自己依據自己情況具體分析。

public class Account
   {
       #region 屬性
       /// <summary>
       /// 帳號登錄的順序號碼
       /// </summary>
       public int ID { get; set; }
       /// <summary>
       /// QQ帳號
       /// </summary>
       public string Uin { get; set; }
       public List<string> Froms { get; set; }
       public string Mail { get; set; }
       /// <summary>
       /// 昵稱
       /// </summary>
       public string Nick { get; set; }
       /// <summary>
       /// 我的首頁
       /// </summary>
       public string MyPage { get; set; }
       /// <summary>
       /// QQ未加密的密碼
       /// </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微博對應的Sid
       /// </summary>
       public string Sid { get; set; }
       /// <summary>
       /// 目前帳號的狀態
       /// </summary>
       public Status CurrentStatus { get; set; }
       /// <summary>
       /// 帳號類型
       /// </summary>
       public AccountStyle AccountStyle { get; set; }
       /// <summary>
       /// 是否需要驗證碼
       /// </summary>
       public bool NeedVerify { get; set; }
       /// <summary>
       /// 驗證碼圖片
       /// </summary>
       public Image VerifyImage { get; set; }
       /// <summary>
       /// 驗證碼字符串
       /// </summary>
       public string VerifyCode { get; set; }
       
       #endregion
       #region 構造函數
       public Account()
       {
           Init();
       }
       public Account(string uin, string password)
       {
           this.Uin = uin;
           this.Password = password;
           Init();
       }
       #endregion
       #region 私有函數
       private void Init()
       {
           this.WeiboCookieContainer = new CookieContainer();
           this.CurrentStatus = Status.Unlogin;
           this.AccountStyle = AccountStyle.Unknow;
       }
       #endregion
}
}

上面的那些都不是關鍵，我們要做的第一步還是完成“判斷驗證碼>輸入驗證碼（如果有的話）>登錄”，除了要我完成Http模擬請求之外還要從返回的結果中提取有用的信息。

 #region 登錄過程
       /// <summary>

           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;
           }
         
       }

           Stream stream = HttpHelper.GetStream(url, this.WeiboCookieContainer);
           Image image = Image.FromStream(stream);
           return image;
       }
       /// <summary>
       /// 登錄

       /// <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("沒有添加帳號，或帳號的密碼為空");
           if (string.IsNullOrEmpty(verifyCode))
               throw new Exception("驗證碼為空，無法繼續登錄");
           this.P = QQMd5.Encrypt(uin,password,verifyCode);

                                     uin, this.P, verifyCode);
           html = HttpHelper.GetHtml(url, this.WeiboCookieContainer);
           if (html.Contains("您輸入的驗證碼不正確，請重新輸入"))
               throw new Exception(string.Format("驗證碼輸入不正確"));
           else if (html.Contains("您輸入的帳號或密碼不正確，請重新輸入"))
               throw new Exception(string.Format("帳號或密碼不正確"));

           }
         
           return html;
         }

由於本人不太喜歡用已經做好的輪子去用Json處理類(比如Newtonsoft.net)，所以一般處理都是用的正則表達式，各位也可以自己用JsonObejct類去處理，不用跟我一樣用正則這種笨方法。
3.獲取必要信息[提取微博數據]

 public string GetInfo()
       {string html="";
           try
           {
               string url = "http://t.qq.com";
               html = HttpHelper.GetHtml(url, this.WeiboCookieContainer);
               string pattern = @"href=""(?'mypage'[^""]*)""><u>首頁";
               string mypage = html.Match(pattern, "mypage");
               this.MyPage = mypage;
               if (string.IsNullOrEmpty(mypage)) throw new Exception("獲取微博話題列表失敗");
               pattern = @"boss=""btnWideSideMyNick"">(?'nick'[^<]*)</a>";
               string nick = html.Match(pattern, "nick");
               if (html.Contains("立即開通")) this.CurrentStatus = Status.NotRegist;
               this.Nick = nick;
               html = "成功獲取微博話題列表";
           }
           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 == "最近聯系人") continue;
                   friendInfo.SortId = sortId;
                   friendInfo.GroupId = groupId;
                   friendInfo.QQ = Uin;
                    list.Add(friendInfo);

               }


           }
           return list;
       }

上面這一步不一定是必須的，但是沒有這一步，我們后面所要實現的功能就會很困難。包括發送分享給QQ，這一步，因為要發送的QQ好友的號碼不是真正的號碼，而是一個系統隨機生成的好友序列號的MD5加密字段。因此，我們也無法用於分享QQ給陌生人號碼。

4.分享
