与服务器第一次交互采用Http连接的方式,使用Http方式完成账号登录,游戏房间登录.

账号登录

当玩家按下登录按钮后会连接服务器,采用的是WWW的方式.通过封装的AsyncWWWTask异步任务发送数据到服务器,如果登录成功会获得服务器返回的cookie(会作为登陆房间的凭证).

private void RequestHttpLogin()
        {
            var form = new WWWForm();
            form.AddField("c", (int)MsgType.Login);
            form.AddField("a", Account);
            form.AddField("n", Uri.EscapeDataString(Name));
            var toMd5 = ToMd5(Password);
            form.AddField("p", Uri.EscapeDataString(toMd5));
            form.AddField("ver", Uri.EscapeDataString("1"));
            form.AddField("dev", Uri.EscapeDataString(SystemInfo.deviceUniqueIdentifier));
#if UNITY_ANDROID
            form.AddField("device", Uri.EscapeDataString("android"));
#elif UNITY_IOS
         form.AddField("device", Uri.EscapeDataString("ios"));
#else
        form.AddField("device", Uri.EscapeDataString("pc"));
#endif
            form.AddField("r", 1);
            form.AddField("phonetype", Uri.EscapeDataString(DeviceModel));
            form.AddField("switchacc", 0);
            form.AddField("sign", Uri.EscapeDataString(ToMd5(Md5Key + (int)MsgType.Login)));
            form.AddField("openid", Uri.EscapeDataString(""));
            Service.UIManager.UILoading.SetVisible(true);
            new AsyncWWWTask(p =>
            {
                if (!string.IsNullOrEmpty(p.error))
                {
                    Service.UIManager.ShowPop(Singleton.GetInstance<Localization>().Get(ExcelManager.settings_error[1].error));
                    Debuger.LogError("error:" + p.error.ToString());
                }
                else if (p.isDone)
                {
                    var receiveBytes = new ByteArray();
                    receiveBytes.WriteBytes(p.bytes);
                    var pack = CmdUtil.ParseCmd(receiveBytes);
                    var loginMsg = Serializer.Deserialize<RetLoginMsg>(pack.BodyStream);
                    ID = loginMsg.Id;
                    if (!_cookies.ContainsKey("COOKIE"))
                    {
                        _cookies.Add("COOKIE", p.responseHeaders["SET-COOKIE"]);
                    }

                    Service.UIManager.RoomUI();
                    Service.UIManager.UILoading.SetVisible(false);
                }
            }, Url, form.data).Start();
        }

房间登录

账号登录成功后会弹出登陆房间UI面板,点击登录后会用之前获得的cookie请求登录游戏房间.如果登录成功会获得房间服地址和房间服key,自此Http流程结束.

private void TryInRoom()
        {
            var form = new WWWForm();
            form.AddField("c", (int)MsgType.ReqIntoFRoom);
            form.AddField("ver", Uri.EscapeDataString("1"));
            form.AddField("model", "5");
            form.AddField("scene", Common.SceneId.ToString());
            form.AddField("ticketnum", "0");
            var msgMd5 = ToMd5(Md5Key + (int)MsgType.ReqIntoFRoom);
            form.AddField("sign", Uri.EscapeDataString(msgMd5));
            Service.UIManager.UILoading.SetVisible(true);
            new AsyncWWWTask(p =>
            {
                if (!string.IsNullOrEmpty(p.error))
                {
                    Service.UIManager.ShowPop(ExcelManager.settings_error[3].error);
                    Debuger.LogError(p.ToString());
                }
                else if (p.isDone)
                {
                    var receiveBytes = new ByteArray();
                    receiveBytes.WriteBytes(p.bytes);
                    var pack = CmdUtil.ParseCmd(receiveBytes);
                    if (pack.CmdId == (uint)MsgType.ErrorMsg)
                    {
                        Service.UIManager.ShowPop(ExcelManager.settings_error[3].error);
                        Debug.LogError(MsgType.ErrorMsg);
                        return;
                    }
                    var retIntoFRoom = Serializer.Deserialize<RetIntoFRoom>(pack.BodyStream);
                    RoomServerkey = retIntoFRoom.Key;
                    Dispatch(Module.EModele.Network_Tcp, new Message(TcpConnection.EMessageKey.RoomServer.ToString(), retIntoFRoom.Addr));
                }
            }, Url, form.data, _cookies).Start();
        }

扩展:

异步任务:AsyncWWWTask继承自GameBox异步任务,通过IsDone检测异步任务是否完成,然后通过回调触发外部逻辑.

public class AsyncWWWTask : AsyncTask
    {
        private WWW www;
        private Action<WWW> wwwEvent;

        public AsyncWWWTask(Action<WWW> wwwEvent, string url, byte[] data = null, Dictionary<string, string> cookies = null) : base(false)
        {
            this.wwwEvent = wwwEvent;
            if (cookies == null)
            {
                if (data == null)
                {
                    this.www = new WWW(url);
                }
                else
                {
                    this.www = new WWW(url, data);
                }
            }
            else
            {
                this.www = new WWW(url, data, cookies);
            }
        }
        protected override bool IsDone()
        {
            if (this.www.isDone)
            {
                this.wwwEvent(this.www);

                return true;
            }
            return false;
        }
