登录鉴权

调用 login接口进行账号登录。

登录鉴权的详细说明请参见账号集成与登录。

  NERoomKit.instance.authService.login(account, token).then((value){
       if(value.isSuccess()){
         print("login success");
       }else{
         print("login failed,code:${value.code},msg:${value.msg}");
       }
    });

主播开播

  1. 主播调用 createRoom 接口创建房间。

    创建房间麦位 NESeatInitParams 参数说明：

    参数 类型 描述
    seatCount int 麦位数量
    seatRequestApprovalMode int 从 NESeatRequestApprovalMode 内获取麦位申请审批模式。
    • OFF：关闭审批模式，即成员提交申请后不需要管理员同意，可直接上麦。
    • ON：开启审批模式，即成员提交申请后需要管理员同意才能上麦。
    seatInvitationConfirmMode int 麦位邀请确认模式。
    • OFF： 关闭确认模式，即管理员邀请其他成员上麦，不需要被邀请的成员确认，可直接上麦。
    • ON：开启确认模式，即管理员邀请其他成员上麦，需要被邀请的成员确认，接受后方可上麦。

    示例代码如下：

        NERoomService roomService = NERoomKit.instance.roomService;
 String roomUuid="123";
 String roomName="roomName";
 int templateId= 21;
 String password = "12345";
 Map<String,String> initialProperties = new HashMap<String,String>();
 initialProperties.put("custom-property-key0", "custom-property-value0");
 initialProperties.put("custom-property-key1", "custom-property-value1");
 /// 设置麦位数量8个，麦位申请需要审批。房主邀请上麦不需要观众同意
 NESeatInitParams seatInitParams =  NESeatInitParams(8，NESeatRequestApprovalMode.ON,NESeatInvitationConfirmMode.OFF);
 NECreateRoomParams params= NECreateRoomParams(roomUuid,roomName,templateId, password,seatInitParams, initialProperties);
 NECreateRoomOptions options =  NECreateRoomOptions();
 roomService.createRoom(params, options).then((value){
   if(value.isSuccess()){
     print("create room success");
   }else{
     print("create room failed");
   }
 });

  2. 主播调用 joinRoom接口加入房间。

    示例代码如下：

      NERoomService roomService = NERoomKit.instance.roomService;
 String roomUuid="123";
 String userName="userName";
 String role="host";//从模板获取角色名称，比如PK直播的场景中的角色名为：host,invited_host,audience
 String password = "password"; //设置为null，表示没有密码
 Map<String,String> initialProperties = new HashMap<String,String>();
 initialProperties["custom-property-key0"]="custom-property-value0";
 initialProperties["custom-property-key1"]="custom-property-value1";
 roomService.joinRoom( NEJoinRoomParams(userName: userName, role: role, roomUuid: roomUuid,password: password,
     initialMyProperties: initialProperties),  NEJoinRoomOptions()).then((value){
   if(value.isSuccess()){
     print("join room success");
   }else{
     print("join room failed");
   }
 });

  3. 调用 joinRtcChannel 接口加入音视频房间。

    示例代码如下：

        NERoomService roomService = NERoomKit.instance.roomService;
 NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
 if (roomContext!=null){
   roomContext.rtcController.joinRtcChannel();
 }

  4. 调用 addEventCallback 接口监听房间里的事件。

    示例代码如下：

    NERoomService roomService = NERoomKit.instance.roomService;
 NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
 if (roomContext!=null){
   roomContext.addEventCallback(NERoomEventCallback(
     roomEnd:(NERoomEndReason reason){
       
     },
     roomPropertiesChanged:(Map<String, String> properties){
       
     },
     roomPropertiesDeleted:(Map<String, String> properties){},
     memberPropertiesChanged:(NERoomMember member, Map<String, String> properties){
       
     },
     memberPropertiesDeleted:(NERoomMember member, Map<String, String> properties){

     },
     memberRoleChanged:(NERoomMember member, NERoomRole oldRole, NERoomRole newRole){

     },
     memberNameChanged:(NERoomMember member, String name){
       
     },
     memberJoinRoom:(List<NERoomMember> members){

     },
     memberLeaveRoom:(List<NERoomMember> members){

     },
     memberJoinRtcChannel:(List<NERoomMember> members){

     },
     memberLeaveRtcChannel:(List<NERoomMember> members){

     },
     rtcChannelError:(int code){

     },
     memberJoinChatroom:(List<NERoomMember> members){

     },
     memberLeaveChatroom:(List<NERoomMember> members){

     },
     memberAudioMuteChanged:(NERoomMember member, bool mute, NERoomMember? operateBy){

     },
     memberVideoMuteChanged:(NERoomMember member, bool mute, NERoomMember? operateBy){

     },
     memberScreenShareStateChanged:(NERoomMember member, bool isSharing, NERoomMember? operateBy){

     },
     chatroomMessagesReceived:(List<NERoomChatMessage> messages){

     },
     liveStateChanged:(NERoomLiveState state){

     },
     rtcAudioVolumeIndication:(List<NEMemberVolumeInfo> volumes, int totalVolume){

     },
     rtcAudioOutputDeviceChanged:(NEAudioOutputDevice device){

     },
     rtcAudioMixingStateChanged:(int reason){

     },
   ));
 }

  5. 收到加入成功的 memberJoinRoom 回调后，调用 unmuteMyAudio 方法开启本地音频采集。

    示例代码如下：

    NERoomService roomService = NERoomKit.instance.roomService;
 NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
 if (roomContext != null) {
   roomContext.rtcController.unmuteMyAudio();
 }

6.调用 submitSeatRequest 方法上麦。

示例代码如下：

  var _currentRoomContext= NERoomKit.instance.roomService.getRoomContext(roomUuid);
  if (_currentRoomContext != null) {
  var ret = await _currentRoomContext!.seatController
      .submitSeatRequest(seatIndex, exclusive);
  commonLogger.i('submitSeatRequest,ret:$ret');
  return ret;
} else {
  commonLogger.e("_currentRoomContext == null");
  return Future.value(const NEResult(
      code: NEVoiceRoomErrorCode.failure, msg: ERROR_MSG_NOT_IN_ROOM));
}

观众进入房间

  1. 观众调用 joinRoom接口加入房间。
   NERoomService roomService = NERoomKit.instance.roomService;
     String roomUuid="123";
     String userName="userName";
     String role="host";//从模板获取角色名称，比如PK直播的场景中的角色名为：host,invited_host,audience
     String password = "password"; //设置为null，表示没有密码
     Map<String,String> initialProperties = new HashMap<String,String>();
     initialProperties["custom-property-key0"]="custom-property-value0";
     initialProperties["custom-property-key1"]="custom-property-value1";
     roomService.joinRoom( NEJoinRoomParams(userName: userName, role: role, roomUuid: roomUuid,password: password,
         initialMyProperties: initialProperties),  NEJoinRoomOptions()).then((value){
       if(value.isSuccess()){
         print("join room success");
       }else{
         print("join room failed");
       }
     });
  1. 观众调用 addEventCallback 接口监听房间里的事件。
  NERoomService roomService = NERoomKit.instance.roomService;
     NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
     if (roomContext!=null){
       roomContext.addEventCallback(NERoomEventCallback(
         roomEnd:(NERoomEndReason reason){

         },
         roomPropertiesChanged:(Map<String, String> properties){

         },
         roomPropertiesDeleted:(Map<String, String> properties){},
         memberPropertiesChanged:(NERoomMember member, Map<String, String> properties){

         },
         memberPropertiesDeleted:(NERoomMember member, Map<String, String> properties){

         },
         memberRoleChanged:(NERoomMember member, NERoomRole oldRole, NERoomRole newRole){

         },
         memberNameChanged:(NERoomMember member, String name){

         },
         memberJoinRoom:(List<NERoomMember> members){

         },
         memberLeaveRoom:(List<NERoomMember> members){

         },
         memberJoinRtcChannel:(List<NERoomMember> members){

         },
         memberLeaveRtcChannel:(List<NERoomMember> members){

         },
         rtcChannelError:(int code){

         },
         memberJoinChatroom:(List<NERoomMember> members){

         },
         memberLeaveChatroom:(List<NERoomMember> members){

         },
         memberAudioMuteChanged:(NERoomMember member, bool mute, NERoomMember? operateBy){

         },
         memberVideoMuteChanged:(NERoomMember member, bool mute, NERoomMember? operateBy){

         },
         memberScreenShareStateChanged:(NERoomMember member, bool isSharing, NERoomMember? operateBy){

         },
         chatroomMessagesReceived:(List<NERoomChatMessage> messages){

         },
         liveStateChanged:(NERoomLiveState state){

         },
         rtcAudioVolumeIndication:(List<NEMemberVolumeInfo> volumes, int totalVolume){

         },
         rtcAudioOutputDeviceChanged:(NEAudioOutputDevice device){

         },
         rtcAudioMixingStateChanged:(int reason){

         },
       ));
     }

  1. 观众调用 muteMyAudio 方法关闭本地音频采集。

    等到上麦后，再开启本地音频采集。

  NERoomService roomService = NERoomKit.instance.roomService;
     NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
     if (roomContext != null) {
       roomContext.rtcController.muteMyAudio();
     }

麦位管理

添加麦位事件监听

调用 addEventCallback 接口，监听麦位相关的事件。

示例代码如下：

   NEVoiceRoomEventCallback eventCallback = NEVoiceRoomEventCallback(
        memberAudioMuteChangedCallback: (member, mute, operateBy) {
      _notifyMemberAudioMuteChanged(member, mute, operateBy);
    }, memberAudioBannedCallback: (member, banned) {
      _notifyMemberAudioBanned(member, banned);
    }, seatRequestSubmittedCallback: (seatIndex, account) {
      _notifySeatRequestSubmitted(seatIndex, account);
    }, seatRequestCancelledCallback: (seatIndex, account) {
      _notifySeatRequestCancelled(seatIndex, account);
    }, seatRequestApprovedCallback:
            (seatIndex, account, operateBy, isAutoAgree) {
      _notifySeatRequestApproved(seatIndex, account, operateBy, isAutoAgree);
    }, seatRequestRejectedCallback: (seatIndex, account, operateBy) {
      _notifySeatRequestRejected(seatIndex, account, operateBy);
    }, seatLeaveCallback: (seatIndex, account) {
      _notifySeatLeave(seatIndex, account);
    }, seatKickedCallback: (seatIndex, account, operateBy) {
      _notifySeatKicked(seatIndex, account, operateBy);
    }, seatInvitationAcceptedCallback: (seatIndex, account, isAutoAgree) {
      _notifySeatInvitationAccepted(seatIndex, account, isAutoAgree);
    }, seatListChangedCallback: (seatItems) {
      _notifySeatListChanged(seatItems);
    });
    NEVoiceRoomKit.instance.addVoiceRoomListener(eventCallback);

主播邀请观众上麦

  • 主播调用 sendSeatInvitation 接口邀请观众上麦。
     String userId = "56789";
 int index=2;
 NERoomService roomService = NERoomKit.instance.roomService;
 NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
 if (roomContext != null) {
   roomContext.seatController.sendSeatInvitation(index,userId);
 }

主播同意观众上麦

主播调用 approveSeatRequest 接口同意观众上麦。

   String userId = "56789";
    NERoomService roomService = NERoomKit.instance.roomService;
    NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
    if (roomContext != null) {
      roomContext.seatController.approveSeatRequest(userId);
    }

主播拒绝观众上麦

主播调用 rejectSeatRequest 接口拒绝观众上麦。

    String userId = "56789";
    NERoomService roomService = NERoomKit.instance.roomService;
    NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
    if (roomContext != null) {
      roomContext.seatController.rejectSeatRequest(userId);
    }

主播将观众移出麦位

主播调用 kickSeat 接口将观众移出麦位。

    String userId = "56789";
    NERoomService roomService = NERoomKit.instance.roomService;
    NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
    if (roomContext != null) {
      roomContext.seatController.kickSeat(userId);
    }

观众申请上麦

观众调用 submitSeatRequest 接口申请上麦。

  int index=1;
    NERoomService roomService = NERoomKit.instance.roomService;
    NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
    if (roomContext != null) {
      roomContext.seatController.submitSeatRequest(index,exclusive);
    }

观众取消申请上麦

观众调用 cancelSeatRequest 接口取消申请上麦。

   NERoomService roomService = NERoomKit.instance.roomService;
    NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
    if (roomContext != null) {
      roomContext.seatController.cancelSeatRequest();
    }

观众主动下麦

观众调用 leaveSeat 接口下麦。

   NERoomService roomService = NERoomKit.instance.roomService;
    NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
    if (roomContext != null) {
      roomContext.seatController.leaveSeat();
    }

离开房间

  1. 调用 leaveRoom 接口离开房间。

    示例代码如下：

    NERoomService roomService = NERoomKit.instance.roomService;
NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
if (roomContext != null) {
  roomContext.leaveRoom();
}

  2. 离开房间成功后，会触发 NERoomEventCallback.memberLeaveRoom 回调，通知房间内所有成员。

  3. 主播调用 endRoom 接口删除房间。

    示例代码如下：

     NERoomService roomService = NERoomKit.instance.roomService;
NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
if (roomContext != null) {
  roomContext.endRoom();
}

  4. 删除房间成功后，会触发 NERoomEventCallback 协议中的 roomEnd 回调方法。

进阶功能

伴音

  1. 调用 RtcController 的 <a href =https://doc.yunxin.163.com/neroom/api-docs/neroom_Flutter_zh/NERoom_Flutter_API_Reference/netease_roomkit/NERoomRtcController/startAudioMixing" target="_blank">startAudioMixing 方法播放伴音。

startTimeStamp long 音乐文件开始播放的时间，UTC 时间戳，即从1970 年 1 月 1 日 0 点 0 分 0 秒开始到事件发生时的毫秒数。默认值为 0，表示立即播放。
sendWithAudioType NERoomRtcAudioStreamType 伴音跟随音频主流还是辅流，默认跟随主流。
  • NERtcAudioStreamTypeMain：伴音跟随主流
  • NERtcAudioStreamTypeSub：伴音跟随辅流

  1. 设置伴音的音量。

    • 通过 setAudioMixingSendVolume 设置伴音的发送音量
    • 通过 setAudioMixingPlaybackVolume 设置伴音的播放音量。

  2. 在离开房间前调用 stopAudioMixing 结束伴音。

示例代码如下：

 NERoomService roomService = NERoomKit.instance.roomService;
    NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
    String path = "music path";
    int loopCount = 1;
    bool sendEnabled = true;
    int sendVolume = 100;
    bool playbackEnabled = true;
    int playbackVolume = 100;
    int startTimeStamp = 0;
    NERoomRtcAudioStreamType sendWithAudioType = NERoomRtcAudioStreamType.NERtcAudioStreamTypeMain
    NECreateAudioMixingOption options =  NECreateAudioMixingOption(path:path,loopCount,sendEnabled,playbackEnabled,sendVolume,
        playbackVolume,startTimeStamp,sendWithAudioType);
    if (roomContext != null) {
      roomContext.rtcController.startAudioMixing(options);
    }
    if (roomContext != null) {
      roomContext.rtcController.setAudioMixingSendVolume(80);
    }

    if (roomContext != null) {
      roomContext.rtcController.setAudioMixingPlaybackVolume(80);
    }

    if (roomContext != null) {
      roomContext.rtcController.stopAudioMixing();
    }

音效

  1. 调用 RtcController 的 playEffect 方法播放音效。

    NECreateAudioEffectOption 参数说明如下表所示。

    参数 类型 描述
    path String 待播放的音乐文件的绝对路径或 URL 地址，支持本地 SD 卡中的绝对路径或 URL 地址
    loopCount int 音效循环播放的次数。1：（默认）播放一次。≤ 0：无限循环播放
    sendEnabled boolean 是否将音效发送远端，默认为 true，即远端用户可以听到该音效。
    sendVolume int 音效文件的发送音量，取值范围为 0~200。默认为 100，表示使用文件的原始音量。
    playbackEnabled boolean 是否本地播放音效。默认为 true，即本地用户可以听到该音效。
    playbackVolume int 音乐文件的播放音量，取值范围为 0~200。默认为 100，表示使用文件的原始音量。
    startTimeStamp long 音乐文件开始播放的时间，UTC 时间戳，即从1970 年 1 月 1 日 0 点 0 分 0 秒开始到事件发生时的毫秒数。默认值为 0，表示立即播放。
    sendWithAudioType NERoomRtcAudioStreamType 伴音跟随音频主流还是辅流，默认跟随主流。
    • kNERtcAudioStreamTypeMain：伴音跟随主流
    • kNERtcAudioStreamTypeSub：伴音跟随辅流

  2. 设置音效的音量。

    • 调用 setEffectSendVolume 方法设置音效文件发送音量。

    • 调用 setEffectPlaybackVolume 方法设置音效文件播放音量。

  3. 在离开房间前，调用 stopAllEffects 方法停止播放所有音效文件。

示例代码如下：

  NERoomService roomService = NERoomKit.instance.roomService;
    NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
    String path = "effect file path";
    int loopCount = 1;
    bool sendEnabled = true;
    int sendVolume = 100;
    bool playbackEnabled = true;
    int playbackVolume = 100;
    int startTimeStamp = 0;
    NERoomRtcAudioStreamType sendWithAudioType = NERoomRtcAudioStreamType.NERtcAudioStreamTypeMain
    NECreateAudioEffectOption options = NECreateAudioEffectOption(path:path,loopCount,sendEnabled,sendVolume,
        playbackEnabled,playbackVolume,startTimeStamp,sendWithAudioType);
    if (roomContext != null) {
      roomContext.rtcController.playEffect(options);
    }
    if (roomContext != null) {
      roomContext.rtcController.setEffectSendVolume(0, 80);
    }

    if (roomContext != null) {
      roomContext.rtcController.setEffectPlaybackVolume(0, 80);
    }

    if (roomContext != null) {
      roomContext.rtcController.stopAllEffects();
    }

耳返

  1. 通过 rtcAudioOutputDeviceChanged 监听播放设备的变化，当监听到播放设备切换为耳机时才开启耳返。

        _roomEventCallback = NERoomEventCallback(
      rtcAudioOutputDeviceChanged: _notifyAudioOutputDeviceChanged,
    );
      void _notifyAudioOutputDeviceChanged(NEAudioOutputDevice device) {
    switch(device){
      case NEAudioOutputDevice.kWiredHeadset:
        print("有线耳机");
        break;
      case NEAudioOutputDevice.kSpeakerPhone:
        print("扬声器");
        break;
      case NEAudioOutputDevice.kEarpiece:
        print("听筒");
        break;
      case NEAudioOutputDevice.kBluetoothHeadset:
        print("蓝牙耳机");
        break;
    }
  }

  2. 调用 enableEarBack 方法开启耳返。

      NERoomService roomService = NERoomKit.instance.roomService;
        int volumn = 100; // 耳返音量 默认100
            NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
            if (roomContext != null) {
                roomContext.rtcController.enableEarBack(volumn);
            }

  3. 调用 disableEarBack 方法关闭耳返。

    NERoomService roomService = NERoomKit.instance.roomService;
NERoomContext? roomContext = roomService.getRoomContext(roomUuid);
if (roomContext != null) {
    roomContext.rtcController.disableEarBack();
}
