javascript - id为 X 的 QBWebRTC 目前正忙？ QB.webrtc.onRemoteStreamListener 未触发。 Quickblox Javascript SDK + Angular + WebRTC

Question

我按照文档操作了三遍以上，但无法接听电话。这是代码:

$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 ID 为 6184 和 6186 的用户。我正在从用户 6186 发起调用，控制台显示以下内容:

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

quickblox.min.js:86149 [QBWebRTC]: _clearDialingTimer
quickblox.min.js:86149 [QBWebRTC]: onIceConnectionStateCallback: closed

现在，在接听端，我看到正在生成一个调用，但随后它说发起调用者正忙:

[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

有人可以告诉我这里发生了什么以及为什么 QB.webrtc.onRemoteStreamListener 在应答端没有触发？

还有一件事:

在我点击“结束通话”后，我收到此错误，我也不明白，因为它的英语也很糟糕:

[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

I am initiating the call from User 6186 and the console

您不必在占用者中列出当前用户的 ID:

所以而不是

$scope.occupants = [6184, 6186];

你应该使用

$scope.occupants = [6184];
