(cache) 先生、こいつまたゴミコード書いてます

こちらで配布してるNicoLiveSeatSharpのコードを解説したいと思います。

②halxxxxさんのクッキー取得ライブラリを使ってブラウザクッキーからセッション取得

            ICookieGetter cookieGetter = CookieGetter.CreateInstance(BrowserType.GoogleChrome3);
            
            CookieCollection cke = cookieGetter.GetCookieCollection(uri);
            
            cContainer.Add(uri, cke);

③認証1にアクセス。

            string login_url = @"https://secure.nicovideo.jp/secure/login?site=nicolive_antenna";

            HttpWebRequest login_request = (HttpWebRequest)HttpWebRequest.Create(login_url);
            login_request.Method = "POST";
            string login_info = "mail=" + mail + "&" + "password=" + pswd;
            byte[] login_info_byteData = Encoding.UTF8.GetBytes(login_info);
            login_request.ContentLength = login_info_byteData.Length;
            login_request.ContentType = "application/x-www-form-urlencoded";
            CookieContainer cookie = new CookieContainer();
            login_request.GetRequestStream().Write(login_info_byteData, 0, login_info_byteData.Length);
            HttpWebResponse login_response = (HttpWebResponse)login_request.GetResponse();
            StreamReader test = new StreamReader(login_response.GetResponseStream());

            Regex getticket = new Regex(@"nicolive_antenna_\d*");
            string ticket = getticket.Match(test.ReadToEnd()).Value;

            return ticket;

ここでは④で必要になる認証チケットを取得しその値を返す。

④認証2にアクセス。

            string login_url = @"http://live.nicovideo.jp/api/getalertstatus";

            HttpWebRequest login_request = (HttpWebRequest)HttpWebRequest.Create(login_url);
            login_request.Method = "POST";
            string login_info = "ticket=" + ticket;
            byte[] login_info_byteData = Encoding.UTF8.GetBytes(login_info);
            login_request.ContentLength = login_info_byteData.Length;
            login_request.ContentType = "application/x-www-form-urlencoded";
            login_request.GetRequestStream().Write(login_info_byteData, 0, login_info_byteData.Length);
            HttpWebResponse login_response = (HttpWebResponse)login_request.GetResponse();
            StreamReader test = new StreamReader(login_response.GetResponseStream());


            string res = test.ReadToEnd();


            return res;

レスポンスをそのまま返してmainの方でパターンマッチする

⑤認証2のレスポンスからコメントサーバーのアドレス、ポート、スレッドIDを取得

　Regex.Match()メソッドを使いまくってる。

　ちなみにString.Replace()メソッドの存在を知らなかったのでタグの削除も全部Regexでやってる。これ治そうと思ってたんだけど忘れてた。コード略

⑥ソケット通信で番組開始通知を受信する準備

IPAddress host_ip = Dns.GetHostEntry(host).AddressList[0];
            IPEndPoint ipe = new IPEndPoint(host_ip, port);
            Socket AlartServerConnection = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            AlartServerConnection.Connect(ipe);
            Console.WriteLine("Connection established.");
            Console.WriteLine("Connection enabled = " + AlartServerConnection.Connected.ToString());
            string sendMsg = String.Format("<thread thread=\"" + thread + "\" version=\"20061206\" res_from=\"-1\"/>\0");
            byte[] sendBytes = Encoding.UTF8.GetBytes(sendMsg);
            int i = AlartServerConnection.Send(sendBytes, 0, sendBytes.Length, SocketFlags.None);
            Console.WriteLine("Request sent. size was {0} byte[s]", i);
            byte[] resBytes = new byte[1024];


            Regex getliveinfo = new Regex(@"(\d*),(co\d*),(\d*)");
            Regex getliveinfo2 = new Regex(",");
            
            Console.Clear();

最初はTcpClientとか使ってみてたけどなんか思った動作が実現できなかったのでSocketに切り替え。通信周りのコードは修正したいけど動かなくなりそうで怖い

⑦プッシュのリクエストを送信

while (true) {
                int size = AlartServerConnection.Receive(resBytes, resBytes.Length, 0);
                if (size == 0) {
                    break;
                }
                string data = Encoding.UTF8.GetString(resBytes, 0, resBytes.Length);
                
........

⑧受信した情報をもとにgetplayerstatusで座席を確保

HttpWebRequest LiveSeat = (HttpWebRequest)HttpWebRequest.Create(getplayerstatus + "lv" + lv);
            LiveSeat.Method = "POST";
            LiveSeat.CookieContainer = cContainer;
            //LiveSeat.UserAgent = "NicoLiveAlert 1.0.2";
            //LiveSeat.Headers.Add("Cookie", "user_session=" + session);
            StreamReader sr = new StreamReader(LiveSeat.GetResponse().GetResponseStream());
            string getplayerstatus_res = sr.ReadToEnd();

            if(require_community_member.IsMatch(getplayerstatus_res)){
                //Console.WriteLine("コミュニティ限定放送");
                return;
            }else if(unknown_error.IsMatch(getplayerstatus_res)){
                Console.WriteLine("不明なエラー");
                return;
            }
            string room = roomlabel.Match(getplayerstatus_res).Value;
            room = room.Replace("<room_label>","");
            Console.Write(Convert.ToString(counter_b%20)+":"+room+"-");
            string seet = seetno.Match(getplayerstatus_res).Value;
            seet = seet.Replace("<room_seetno>", "");
            Console.Write(seet+"番席確保\t");
            access[counter_b % 20] = live[0];
            string title = gettitle.Match(getplayerstatus_res).Value;
            title = title.Replace("<title>", "");
            Console.WriteLine(title);
            counter_b++;
