ID为X的QBWebRTC此时正忙？ QB.webrtc.onRemoteStreamListener未触发。 Quickblox Javascript SDK + angular + WebRTC

Question

我已经跟随了三次文档，我无法接受电话。下面是代码：

$scope.occupants = [6184, 6186]; 
$scope.session = QB.webrtc.createNewSession($scope.occupants, QB.webrtc.CallType.VIDEO); 
$scope.localMediaParams = { 
    audio: true, 
    video: true, 
    options: { 
     muted: true, 
     mirror: true 
    }, 
    elemId: 'localVideoEl', 
    optional: { 
     minWidth: 240, 
     maxWidth: 320, 
     minHeight: 160, 
     maxHeight: 240 
    } 
}; 

$scope.startCall = function() { 
    if (angular.equals($scope.recipients, {})) { 
     alert('Please choose a person to call'); 
    }else { 
     if (angular.equals($scope.session, {})) { 
      console.log('session hasn\'t been started'); 
      $scope.session.stop({}); 
      $scope.session = {}; 
      return false; 
     }else { 
      $scope.session.getUserMedia($scope.localMediaParams, function(err, stream) { 
       if (err){ 
        console.log(err); 
       }else{ 
        console.log(stream); 
        $scope.session.call({}, function(error) { 
         console.log(error); 
        }); 
       } 
      }); 
     } 
    } 
}; 
$scope.answerCall = function() { 
    $scope.session.getUserMedia($scope.localMediaParams, function(err, stream) { 
     if (err){ 
      console.log(err); 
      $scope.session.stop({}); 
     }else{ 
      console.log(stream); 
      $scope.session.accept({}); 
     } 
    }); 
}; 
QB.webrtc.onRemoteStreamListener = function(session, userID, remoteStream) { 
    // attach the remote stream to DOM element 
    console.log('onRemoteStreamListener'); 
    console.log($scope.session); 
    $scope.session.attachMediaStream('remoteVideoEl', remoteStream); 
}; 

我有两个用户ID的6184和6186.我开始从用户6186的呼叫，并在控制台显示此：

[QBWebRTC]: RTCPeerConnection init. userID: 6186, sessionID: 7e7ea17c-a207-4af0-82e1-744fbcce830e, type: offer

现在的anwering边我看到产生一个呼叫，但随后说，发起呼叫者忙：

[QBWebRTC]: onCall. UserID:6186. SessionID: 7e7ea17c-a207-4af0-82e1-744fbcce830e 
quickblox.min.js:86149 [QBWebRTC]: User with id 6186 is busy at the moment. 
quickblox.min.js:86149 [QBWebRTC]: onStop. UserID:6186. SessionID: 7e7ea17c-a207-4af0-82e1-744fbcce830e 

谁能告诉我是怎么回事就在这里，为什么QB.webrtc.onRemoteStreamListener不火的应答侧？

一两件事：

我打完电话后，我得到这个错误，我也搞不懂，因为它也有坏英语：

[QBWebRTC]: onStop. UserID:6186. SessionID: 7e7ea17c-a207-4af0-82e1-744fbcce830e 
quickblox.min.js:86161 [QBWebRTC]: Ignore 'onStop', there is no information about session 7e7ea17c-a207-4af0-82e1-744fbcce830e by some reason. 

Answer 1

我无法接受呼叫的原因是，我是不重视从QB.webrtc.onCallListener监听流。

QB.webrtc.onCallListener = function(session, extension) { 
      $scope.session = session; 
      console.log('User '+session.currentUserID+' is calling'); 
     }; 

的文档没有解释什么用户需要的乘客阵列，以及你应该随大流做什么，一旦它击中的是听众。从角度来看，你应该得到一个$ scope.session，或者如果你没有将QB.webrtc.onCallListener流附加到会话或$ scope.session对象中，会话是未定义的。另外，正如Igor指出的那样，您不应该将用户ID包含在占用者数组中。

Answer 2

我开始从通话用户6186和控制台

你不必列出当前用户的ID在乘客：

所以不是

$scope.occupants = [6184, 6186]; 

你应该使用

$scope.occupants = [6184];
