Quickblox Javascript SDK + Angular + webRTC - 无法读取未定义的 属性 'send'
Quickblox Javascript SDK + Angular + webRTC - Cannot read property 'send' of undefined
我已经使用 Quickblox Javascript SDK + Angular + webRTC 建立了一个功能齐全的 webRTC 视频会议客户端。一件奇怪的事情发生了，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：

这是 SDK 中发生错误的代码块：
_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 = [];
}
}
当呼叫启动时，一条消息会发送给您尝试连接的对手。
以下是无效通话的消息：

这是我刷新并发起呼叫后的消息：

如您所见，呼叫者 ID 在无效的呼叫中为 NaN，而在有效的呼叫中是正确的。我尝试像这样手动设置此 initiatorID：
$scope.session = QB.webrtc.createNewSession($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');
}
});
}
});
但这不起作用。有人可以解释为什么会这样吗？？
对于每个调用，您需要创建新的 WebRTC 会话。
我找到了这行代码。
$scope.session.call($scope.recipient, function(error) {
console.log(error);
});
尝试调用并设置一个空对象而不是像这样的 $scope.recipient:
$scope.session.call({}, function(error) {
console.log(error);
});
此外，您能否检查 QB.chat.connect 回调中是否存在您的 WebRTC 会话？您可以在此处找到代码示例。
https://github.com/QuickBlox/quickblox-javascript-sdk/blob/gh-pages/samples/webrtc/js/app.js#L236
你的解决方案应该是这样的：
if (!angular.equals($scope.session, {}) && !angular.equals($scope.session, undefined)) {
$scope.session.stop({});
$scope.session = {};
}
calllerId 在这里设置：https://github.com/QuickBlox/quickblox-javascript-sdk/blob/gh-pages/src/modules/webrtc/qbWebRTCClient.js#L93
当您创建一个新会话时，您可以输入您的 ID。你能试着做到吗？
如果这将解决此问题，我认为您在聊天连接方面遇到了问题。
请提供反馈。
因此，如果您遇到错误"Cannot read property 'send' of undefined"，请确保您已初始化 SDK 一次。
如果您正在使用 Angular，请使用此
app.run(function ($rootScope) {
QB.init(QBApp.appId, QBApp.authKey, QBApp.authSecret, config);
});

这是 SDK 中发生错误的代码块：
_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 = [];
}
}
当呼叫启动时，一条消息会发送给您尝试连接的对手。
以下是无效通话的消息：

这是我刷新并发起呼叫后的消息：

如您所见，呼叫者 ID 在无效的呼叫中为 NaN，而在有效的呼叫中是正确的。我尝试像这样手动设置此 initiatorID：
$scope.session = QB.webrtc.createNewSession($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');
}
});
}
});
但这不起作用。有人可以解释为什么会这样吗？？
对于每个调用，您需要创建新的 WebRTC 会话。
我找到了这行代码。
$scope.session.call($scope.recipient, function(error) {
console.log(error);
});
尝试调用并设置一个空对象而不是像这样的 $scope.recipient:
$scope.session.call({}, function(error) {
console.log(error);
});
此外，您能否检查 QB.chat.connect 回调中是否存在您的 WebRTC 会话？您可以在此处找到代码示例。
https://github.com/QuickBlox/quickblox-javascript-sdk/blob/gh-pages/samples/webrtc/js/app.js#L236
你的解决方案应该是这样的：
if (!angular.equals($scope.session, {}) && !angular.equals($scope.session, undefined)) {
$scope.session.stop({});
$scope.session = {};
}
calllerId 在这里设置：https://github.com/QuickBlox/quickblox-javascript-sdk/blob/gh-pages/src/modules/webrtc/qbWebRTCClient.js#L93
当您创建一个新会话时，您可以输入您的 ID。你能试着做到吗？ 如果这将解决此问题，我认为您在聊天连接方面遇到了问题。
请提供反馈。
因此，如果您遇到错误"Cannot read property 'send' of undefined"，请确保您已初始化 SDK 一次。
如果您正在使用 Angular，请使用此
app.run(function ($rootScope) {
QB.init(QBApp.appId, QBApp.authKey, QBApp.authSecret, config);
});
