我们在.Net Framework中拥有一个SignalR服务器,该服务器可同时为Windows和Web客户端提供服务。
对于Web客户端,我们使用为SignalR提供的Javascript库,并将其用于Angular应用程序。
问题适用于以下情况。
如果发件人是Windows应用程序,而收件人是Web应用程序,则除非Web App单击我们具有的“发送消息”按钮,否则Web App不会收到消息。
Web与Windows的情况相同。如果Web应用程序正在发送消息,则仅在Windows应用程序再次发送消息时才会收到消息。
两个都使用相同的集线器,加入了相同的组。
在检查时发现消息确实到达了服务器,但是只有在调用发送消息时才会触发接收消息。
Web到Web和Windows到Windows应用程序运行正常,没有任何问题。
请让我知道是否需要更多信息。
用于集线器连接的Windows代码:
_hubConnection = new HubConnection(signalRHubAddress);
//We Add SAML Token into the header as hub is secured by SAML.
_hubConnection.Credentials = CredentialCache.DefaultCredentials;
_hubConnection.Closed += OnDisconnected;
_hubConnection.Reconnecting += OnReconnecting;
_hubConnection.Error += OnError;
_hubConnection.StateChanged += OnStateChanged;
_hubProxy = _hubConnection.CreateHubProxy(applicationHub);
_hubProxy["environmentName"] = "Environment";
_hubConnection.Start();
_hubProxy.On<string>("JoinGroupMessage", msg => ProcessJoinGroupMessage(msg,false));
_hubProxy.On<string>("ReJoinGroupMessage", msg => ProcessJoinGroupMessage(msg,true));
_hubProxy.On<string>("LeaveGroupMessage", msg => ProcessLeaveGroupMessage(msg));
_hubProxy.On<string>("ReceiveMessage", msg => ProcessReceiveMessage(msg));
Web客户端代码:
$.ajax({
url: hubParam.homeUrl,
type: 'Post',
dataType: "json",
contentType: "application/x-www-form-urlencoded;charset=utf-8",
data: {
SAMLToken: token
},
success: function (Id) {
myHub.assertionId = Id;
myHub.connection = getConnection(hubParam.hubUrl);
myHub.hubProxy = getHubProxy(myHub.connection, hubParam.hubName);
myHub.hubProxy.on(clientFuncName, function (msg) {
callbackFunc(msg);
});
myHub.connection.start().done(function () {
console.log(resources.connectionStarted);
})
.fail(function (err) {
console.log(resources.connectionFailed + err.toString());
});
}
getConnection = function(hubUrl) {
if (myHub.connection == null || myHub.connection === 'undefined') {
myHub.connection = $.hubConnection(hubUrl);
myHub.connection.qs = {
'version': myHub.version
};
}
else if(myHub.connection.state === 4) {
myHub.connection.start();
}
return myHub.connection;
};
getHubProxy = function (hubConn, hubName) {
if (myHub.hubProxy == null || myHub.hubProxy === 'undefined') {
myHub.hubProxy = hubConn.createHubProxy(hubName);
}
return myHub.hubProxy;
};
