我已经建立了一个功能齐全的webRTC视频会议客户端，使用Quickblox Javascript SDK + Angular + webRTC。一件奇怪的事情正在发生，每次我清除缓存并从头开始登录时，当我发起呼叫时，我都会收到以下错误：

有趣的是，如果我刷新页面，它工作正常，完全没有问题。当我遇到$scope问题时，我在开发过程中看到过这种情况，但我已经退缩了，无法确定它何时开始发生。有人可以确定此错误的原因吗？

以下是发生错误的 SDK 中的代码块：
_onIdle: function () {
var data = this._conn._data;
if (data.length > 0 && !this._conn.paused) {
for (var i = 0; i < data.length; i++) {
if (data[i] !== null) {
var stanza, rawStanza;
if (data[i] === "restart") {
stanza = this._buildStream().tree();
} else {
stanza = data[i];
}
rawStanza = Strophe.serialize(stanza);
console.log(rawStanza);
this._conn.xmlOutput(stanza);
this._conn.rawOutput(rawStanza);
// HERE IS WHERE I GET THE ERROR
this.socket.send(rawStanza);
// HERE IS WHERE I GET THE ERROR
}
}
this._conn._data = [];
}
}
当呼叫发起时，会向您尝试连接的对手发送一条消息。
以下是来自呼叫不起作用的消息：

这是我刷新并启动呼叫后的消息：
<message to="6184-5@chatcaduceustelemed.quickblox.com" type="headline" id="58d15c8cd15a7a2513000001" xmlns="jabber:client">

如您所见，呼叫者ID在不起作用的呼叫中是NaN，而在起作用的呼叫上是正确的。我尝试像这样手动设置此启动器 ID：
$scope.session = QB.webrtc.createNewSession($scope.occupants, QB.webrtc.CallType.VIDEO);
$scope.session.initiatorID = $scope.user.id;
$scope.modal = true;
$scope.callWaiting = true;
$scope.session.getUserMedia($scope.localMediaParams, function(err, stream) {
if (err){
console.log(err);
}else{
console.log(stream);
console.log('placing a call to '+$scope.recipient.name);
$scope.session.call($scope.recipient, function(error) {
if(error) {
console.log(error);
} else {
console.log('successfully placed call with no errors');
}
});
}
});
但这行不通。请有人解释为什么会发生这种情况吗？
因此，如果您收到错误"无法读取未定义的属性'发送'"，请确保一次初始化 SDK。
如果您使用的是 Angular，请使用此
app.run(function ($rootScope) {
QB.init(QBApp.appId, QBApp.authKey, QBApp.authSecret, config);
});
对于每个调用，您需要创建新的WebRTC会话。
我找到了这一行代码。
$scope.session.call($scope.recipient, function(error) {
console.log(error);
});
尝试进行调用并设置一个空对象，而不是像这样$scope.收件人：
$scope.session.call({}, function(error) {
console.log(error);
});
另外，你能检查一下，你的WebRTC会话是否存在于QB.chat.connect回调上吗？在这里，您可以找到一个代码示例。
https://github.com/QuickBlox/quickblox-javascript-sdk/blob/gh-pages/samples/webrtc/js/app.js#L236
您的解决方案应如下所示：
if (!angular.equals($scope.session, {}) && !angular.equals($scope.session, undefined)) {
$scope.session.stop({});
$scope.session = {};
}
calllerId 设置在这里： https://github.com/QuickBlox/quickblox-javascript-sdk/blob/gh-pages/src/modules/webrtc/qbWebRTCClient.js#L93
当您创建新会话时，您可以输入您的 ID。 你能尝试这样做吗？ 如果这可以解决此问题，我认为您在聊天连接时遇到问题。
请提供反馈。
