ASP.NET SignalR

IMPORTANT: There will be no new features added to this product. We are in maintenance mode and only fixing critical issues. See our blog post for details. This repository hosts code and project management for ASP.NET SignalR, for use in .NET Framework applications using System.Web or Katana. If you are looking for information on ASP.NET Core SignalR, see the https://github.com/aspnet/AspNetCore/tree/main/src/SignalR repository.

ASP.NET SignalR is a library for ASP.NET developers that makes it incredibly simple to add real-time web functionality to your applications. What is "real-time web" functionality? It's the ability to have your server-side code push content to the connected clients as it happens, in real-time.

What can it be used for?

Pushing data from the server to the client (not just browser clients) has always been a tough problem. SignalR makes it dead easy and handles all the heavy lifting for you.

java-client's Issues

Could not find org.java-websocket:java-websocket:1.3.1.

there isn't version 1.3.1.
I just find the version 1.3.0 . this is the latest version.

Is there any sample about using websocket?

I'm using in this whey:

WebsocketTransport ss = new WebsocketTransport(new Logger() {
@OverRide
public void log(String arg0, LogLevel arg1) {
Log.d("@NewLogger", arg0);
Log.d("@NewLogger", arg1.toString());
}
});

SignalRFuture startFuture = connection
.start(ss );

startFuture.get(60, TimeUnit.SECONDS);

Websockets

It would be great if websockets were supported.

Reconnect event not working!

Im starting connection, then i stop website in iis, wait for 2-3 seconds then i start again. The clients never get in recconect state. In order to reconnect i must create new instance of HubConnection.

'Disconnected' state still even though it was in the connected event

The exception:" The operation is not allowed in the 'Disconnected' state" fires even when I put the sendMessage() inside the connected event (connection.connected(Runnable with my method)). The connected method is called only when it is completely connected, right? Why this exceptions appears? Follow the logger:

Problem with Samsung Galaxy S3. Connection always gets slow (Slow connection detected), falls down and tries repeatedly reconnect but without success.

Always after the connection was established (around 20 seconds), it gets slow and enter in an endless looping of "reconnecting" and "reconnected" sequentially without stopping.
Before SignalR Android be released I was using SignalA (https://github.com/erizet/SignalA) this problem does not occur with SignalA ,so I tried to compare the request of both at the same server. I could notice a difference in the http header and response at the same server (Windows Server 2012 / IIS 8) :

---SignalA Header----
User-Agent: Dalvik/1.6.0 (Linux; U; Android 4.3; GT-I9300 Build/JSS15J)

---SignalR Android Header---
User-Agent: SignalR (lang=Java; os=android; version=2.0)

---SignalA Response Header----
Server: Microsoft-IIS/7.5

---SignalR Android Response Header----
Server: Microsoft-IIS/8.0

Below is the sequence of request, and it remains trying to reconnect infinitely :

FedAuth cookie from ADFS cannot be used as CookieCredential

The FedAuth cookie generated by ADFS contains semicolons and a mix of Base64 encoded text and non-Base64 encoded text. The ARRAffinity cookie generated by Azure also contains semicolons. Neither of these cookies appears to be able to be used with CookieCredential, since the "cookie" header value is delimited by semicolons. How can we use cookies containing semicolons and different encodings?

Example cookie values:

FedAuth=[Base64-encoded token]; expires=Sat, 07-Feb-2015 09:49:31 GMT; path=/; secure; HttpOnly
ARRAffinity=[long number];Path=/;Domain=site.azurewebsites.net

client-test-integration-android : InvalidHttpStatusCodeException

I am trying to run the signalR self-host example server (www.asp.net/signalr/overview/deployment/tutorial-signalr-self-host) with the android test integration. I have tested that the self-host server is accessible by clients written in C# from another machine in the local network (I changed localhost to * on the server). However, I have not been successful yet. I get the following error:

Critical: AutomaticTransport - Error: microsoft.aspnet.signalr.client.http.InvalidHttpStatusCodeException: Invalid status code: 500

The full log can be seen here:

http://pastebin.com/fMPabbN1

Am I missing something? It does not look like a compilation or IP configuration error. If I don't run the server and run the tests, I get socketTimeOut, which is expected.

I ran the "Basic Connection Flow - Auto" test.

Thanks!

Imports not resolving

Hi,

I'm having trouble resolving the imports of the signalr-client-sdk package. I built the jar for signalr-client-sdk and placed all required jars in my android workspace libs folder. I've added the jars to the project build path. Please see the screenshots attached. As you can see the two imports are not resolving. I've cleaned the project and read a few forums but can't get passed this basic step.I hope I'm making a simple mistake. Any advice would be appreciated. Thanks.

Add support for SignalR 1.2.x protocol

Hello guys, thanks for your work!

How can I use the official Java (Android) SDK to communicate with the back-end via SignalR 1.2.x protocol? As far as I can see by SignalR SDK code there is just a hard coded verification for 1.3 version at Connection.verifyProtocolVersion:

java-client/signalr-client-sdk/src/microsoft/aspnet/signalr/client/Connection.java

Line 597 in f226631

private static boolean verifyProtocolVersion(String versionString) {

Will it work for SignalR 1.2.x protocol if I will modify the verification to accept 1.2 also?

Thanks

Does not Disconnect Instantly as connection in SignalR

SignalR Get Connect in an instant. But does not disconnect when the data Connection get closed automatically on the other hand if the Client is a browser Client gets disconnect in an instant if client is closed. Hence Creating Problem, How to disconnect in instant when Client loses Connectivity with Server

ArrayIndexOutOfBoundsException causes disconnect

The following exception occurs at random. I can see in the trace that this has something to do with data which is coming in from the server, but got corrupt during the transfer. When this happens, the connection gets closed immediately.

The environment is an Android phone (Nexus 5) with Lollipop 5.0.1 and the latest version of the SignalR java-client.

I got the following exception from the error callback event:

How to Get a Value by public <E> SignalRFuture<E> invoke(final Class<E> resultClass, final String method, Object... args)

i try the way 1 (by handler)，i can recieve the result, code as below:

hub.on("receiveHelloWorldReturn",
new SubscriptionHandler1() {
@OverRide
public void run(String msg) {

                            Log.i("0.03", "結果" + msg);
                            Toast.makeText(MainActivity.this, msg,
                                    Toast.LENGTH_LONG).show();
                        }
                    }, String.class);
            hub.invoke("HelloWorldReturn");

---

But i try the way 2 ( direct ), i can't receieve the result,

Class resultClass = null;
SignalRFuture str = hub.invoke(resultClass,
"HelloWorld2", "123");
str.done(new Action() {
@OverRide
public void run(String arg0) throws Exception {
Log.i("0.03", "arg0=" + arg0);
}
}).onError(new ErrorCallback() {
@OverRide
public void onError(Throwable error) {
Log.i("0.03", "error=" + error.toString());
}
});

Could Anyone help me, please...

Hangs on Sprint Network

In testing the java-client on several Sprint Android devices (US provider), I've had issues using the Sprint data network where it will hang/wait-for-timeout on the SignalRFuture get() line "mResultSemaphore.tryAcquire(timeout, unit)".

Works fine on AT&T and Verizon data networks and when the Sprint device is on WiFi.

I made a small change locally to SignalRFuture.java in microsoft.aspnet.signalr.client that appears to be working on all networks. I simply updated this:

private Semaphore mResultSemaphore = new Semaphore(0);

to this:

private Semaphore mResultSemaphore = new Semaphore(1);

Just wanted to pass this on.

Calling hub.Invoke() To many times causes an Exception

Hey,
I have been calling the invoke method of the HubProxy class, many times around 40 times each session and after 3 or 4 consecutive sessions the Application would crash with all kind of reasons like

Caused by: android.os.TransactionTooLargeException
android.view.Surface$OutOfResourcesException: eglMakeCurrent failed EGL_BAD_ALLOC
java.lang.RuntimeException: Could not read input channel file descriptors from parcel.

After some investigating i realized that the error is from the invoke method and probably because it's creating to many InputStreamReader or something of that kind.

Hope to get your input about this soon

Thanks

Crashing sometimes when my android app is closing.

The type SubscriptionHandler is not generic; it cannot be parameterized with arguments <String>

i can send message from android client to server use signalR client.
but i want to define methods on the client that the server can call as follow:

public void UpdateStatus( String status )
{
final String fStatus = status;
handler.post(new Runnable(){
@OverRide
public void run() {
statusField.setText( fStatus );
}});
}
but i got a problem when i wrote hub.on()
hub.on( "UpdateStatus",
new SubscriptionHandler() {
@OverRide
public void run( String status ) {
// Since we are updating the UI,
// we need to use a handler of the UI thread.
final String fStatus = status;
handler.post( new Runnable() {
@OverRide
public void run() {
statusField.setText( fStatus );
}
} );
}
}
, String.class );
the new SubscriptionHandler throws an exception:
The type SubscriptionHandler is not generic; it cannot be parameterized with arguments

How can i Set Timeout for SignalR Technology Fallback in SignalR/Client Java

I know if a connection is not made SignalR will fallback from Websocket to SSE to ... to long pooling. I wanna know how can i set Timeout period for each technology to switch for example let us say if a connection is not made in 2 Sec then fallback to another technology. I wanna set those 2 Sec.

How can i create this code in Android.

Can you guys support an ADT less than 4.4.2, it's a deal breaker for my project :(

Verify valid protocol version?

I have asked a question on StackOverflow, but I figuired I would post it here also.

http://stackoverflow.com/questions/22997568/signalr-java-client-only-supports-exactly-1-3

Is there a reason why the Java client for SignalR only supports exactly version 1.3?

java-client/signalr-client-sdk/src/microsoft/aspnet/signalr/client/Connection.java

Line 597 in f226631

private static boolean verifyProtocolVersion(String versionString) {

Shouldn't all clients be backwards compatible? Is there any harm done and changing the verifyProtocolVersion method to verify that the protocol is less than or equal to 1.3?

For testing purposes, I simply returned true, skipping the entire method body, to see if it worked with my 1.2.1 server, and it did.

Maybe this should be considered a bug?

Crash dump on reconnect on Android app

removeSubscription

HubProxy.removeSubscription doesn't seem to be removing client event subscription. Tried unsubscribing from events instantiated with both - HubProxy.subscribe(event) and HubProxy.on(event, handler). When calling removeSubscription, debugger still shows there's a subscription, and on subsequent calls to subscribe again, fires events twice.

Crash dump keeps coming in my android app

Could not find class 'microsoft.aspnet.signalr.client.transport.WebsocketTransport$1', referenced from method microsoft.aspnet.signalr.client.transport.WebsocketTransport.start

Hello,

I cloned the project and built it as it is told in the 'readme' file. On Android client, when I tried to connect my hub. I get this error : Could not find class 'microsoft.aspnet.signalr.client.transport.WebsocketTransport$1', referenced from method microsoft.aspnet.signalr.client.transport.WebsocketTransport.start

any idea?

thanks

Nested json object does not parse correctly.

We are sending(from .net server) an object that looks like this:

{
"created": "2014-09-24T22:29:55.9433573+00:00",
"payload": {
"locationId": "sadfasdfasdf",
"sdid": "adsfasdf",
"timestamp": "2014-09-24T22:29:55.9433573+00:00",
"x": 3.35827106766322,
"y": 28.6876492754964,
"confidenceFactor": 100
},
"subscriptionType": "Update"
}

Ends up receiving (java hub client) parsed into an object that looks like this (the quotes on the payload nested object are missing making it hard to parse the nested object):

{
"created": "2014-09-24T22:29:55.9433573+00:00",
"payload": {locationId:sadfasdfasdf,sdid:adsfasdf,timestamp:2014-09-24T22:29:55.9433573+00:00,x:3.35827106766322,y:28.6876492754964,confidenceFactor:100},
"subscriptionType": "Update"
}

To reproduce this behavior, clone the repository and run the following from the signalr-client-sdk folder:

NOTE: if you have previously cached the Gson package on the build machine, you must first remove the cached bits by doing something like rm -r -f \users\username.m2\repository\com\google\code\gson. Otherwise, it will appear to work fine since it finds the bits locally.

Reconnect doesn't work

In my compilation the test of Reconnecting doesn't pass.

3G Connection

I need to do something special for work with a 3G connection?

My app works fine with Wifi, but doesn't work with a 3G connection.

Hang after calling 'connection.start().get()' on Android.

I'm attempting to run the following code on an Android client using the head revision of the repo:

...
// Change to the IP address and matching port of your SignalR server.
connection = new HubConnection("http://fa-signalr-demo.azurewebsites.net/", "", true, logger);
hub = connection.createHubProxy("chatHub");
...

// This code is an async task so that it wouldn't hang the main thread when debugging.
SignalRFuture<Void> awaitConnection = connection.start();
try {
    awaitConnection.get();
}
catch (InterruptedException e) {
    e.printStackTrace();
} catch (ExecutionException e) {
    e.printStackTrace();
}
...

However the get() function never returns and no connection seems to get established. If I attempt to do anything with the connection object after this point, an exception is thrown as it is in a 'Connecting' state but it never moves from this state.

Befire hanging the last log ouput is:

01-27 21:03:22.512: I/SignalR(13738): HubConnection - Getting connection data: [{"name":"chathub"}]

This is occuring on multiple devices: a Samsung Galaxy S4 with Android 4.4.2 and a Motorola X wtih Android 4.4.4, are the devices I'm using most often.

Has anyone run in a similar problem or can offer any advice?

Thanks

HubProxy.invoke Callbacks are useless.

Please, add callbacks like OnInvokeListener interface. It may invoke OnSuccess(parameters) or OnFail(parameters).

getResult() is useless method for Android UI processing.

For now, i added my OnInvokeListener.

I use it like:
mHubProxy.invoke(methodName, new OnInvokeListener(){
@OverRide
public void OnInvokeDone() {
// TODO: DONE
}
@OverRide
public void OnInvokeError() {
// TODO: ERROR
}
}, arguments);

Modified HubProxy.invoke method:

/**
 * Invokes a hub method that returns a value
 * 
 * @param method
 *            Method name
 * @param mOnInvokeListener
 *            Method callback
 * @param args
 *            Method arguments
 * @return A Future for the operation, that will return the method result

SignalR throws Exceptions in its own threads which aren't handled

Hi,

It appears that the SignalR connection throws unhandled exceptions inside its thread. There is no way to handle them in my application except for defining a global Thread.UncaughtExceptionHandler. This also affects my own threads, so this is not really the greatest solution. The exceptions occur mostly when I call the hubConnection.stop() method. Below I have included an example of Exceptions thrown by the connection Thread (an IndexOutOfBoundsException is also thrown sometimes, I will add the stacktrace when it occurs again):

It would be nice if the exceptions inside threads are handled.

Thanks :)

Signalr Java client disconnected instead of reconnect

Hi
we are using SignalR java client for android app to receive signalr notifications.
We have noticed that when user off the wi-fi,it immediately disconnected from the server instead of calling onreconnect event.It should call to reconnect event and if internet not available with in 30 seconds then it should call to disconnect event.

Depending on Wifi or 3G connection, start method needs LongPollingTransport instance

Hello,

I have an issue with SignalR java-client. it is simply, if my device has a WIFI connection I have to start connection with parameterless start method, otherwise I have to send a LongPollingTransport instance to start method. if I do not do this after a while SignalR disconnects thus it stops working properly.

In this case, I am making user to select what kind of connection his device has, but I really dont want my user to make this choice.

Could you please help me on this? thank you. I appreciate your help.

simply my code is

             lpt = new LongPollingTransport(new Logger() 
    {       
        @Override
        public void log(String message, LogLevel level) 
        {

        }
    });

    SignalRFuture<Void> awaitConnection = null;

    if(!wifi)
     awaitConnection = con.start(lpt);
    else
     awaitConnection = con.start();
    try
    {
        awaitConnection.get();
        connected=true;
        firstStart=false;
    } 
    catch (InterruptedException e)
    {
        ConnectExceptionRecieved();
    }

Yours Sincerely,

Date parsing failure when no milliseconds are in date string

Using the default serialization settings from SignalR 2.0.0, I get dates in the format 2014-03-29T00:00:00 or 2014-03-29T00:00:00Z. I would expect these dates to parse correctly, however I get the following exception:
java.text.ParseException: Unparseable date: "2014-03-29T000000000000:0000"

The only way I have discovered to get the Java client to parse the dates is to change my serialization settings in the SignalR server:

var serializerSettings = new JsonSerializerSettings();
serializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Utc;
serializerSettings.DateFormatHandling = DateFormatHandling.IsoDateFormat;
serializerSettings.Converters.Add(new IsoDateTimeConverter { DateTimeFormat = "yyyy-MM-dd\\THH:mm:ss.fffK", DateTimeStyles = DateTimeStyles.AdjustToUniversal | DateTimeStyles.RoundtripKind});
var serializer = JsonSerializer.Create(serializerSettings);
// Register serializer in IOC

I don't particularly want to make this change, because this format is not desirable for our purposes.
Additionally, the Gson instance in the Java client cannot be overridden so I can't easily substitute my own Date parser.

Is there some obvious setting that I'm missing? I think the following formats should be parsed without error (right now they all throw a ParseException):

• 2014-03-29T00:00:00 (assume UTC, or allow the behaviour to be configured)
• 2014-03-29T00:00:00Z
• 2014-03-29T00:00:00+00:00

I believe this is due to the fact that the DateSerializer implementation is inserting milliseconds, but not the milliseconds separator .. For this reason, 2014-03-29T00:00:00.Z (note the . before the Z) actually parses without error.

If this isn't possible, please allow the Gson instance to be overridden.

Incoming messages are sometimes delayed.

Server messages are sometimes delayed. I have an Android application with a contact list which updates the contact statuses (online/offline) realtime via SignalR. This is working fine, until after a random amount of time (sometimes ~10s, sometimes ~20s, sometimes even >60s). At this point statuses are no longer updated for a random amount of time. When the statuses start to update again, all the updates come through at once and normal behaviour is restored (until it stops and starts again).

This problem occurs on a Nexus 5 connected via Wifi and in an emulator on my desktop (connected via ethernet). The problems do not occur in the web version and the windows phone app, so I am pretty sure that the java-client is the cause of these problem.

I can imagine this issue is related to #54

Can not set Header for HubConnection

I want to add header to HubConnection for authentication but unable to do that!
I try to use this: conn.getHeaders().put(String, String), but it return null.

My app does not work in 3G connections

My app works well in WI-FI Connection. It works perfectly well in 2G as well but whenever i try to connect with 3G, it has issues and most of the time it don't make a connection sometime it makes connection after a long time (I am making a copy of Connection info in my database so i can check connection IDs from there), but rest of the part don't work.

Kindly suggest what kind of changes do i need to apply for 3G connection as i know speed is not the concern because its working in 2G.

LongPolling transport remains in reconnect state until server sends an event.

Hi,

I have an issue with the LongPolling transport. The problem is that when the server doesn't call any of the subscribed methods of the subscription object (provided through hubProxy.subscribe()), the signalr java client signals 'slow connection' and after a few seconds it will land in the reconnect state. When this happens, I am able to send data to the server using the hubProxy.invoke command while the client still stays in reconnect state. The data is handled as expected on the server. So no troubles here. But when I want to disconnect from the server, the connection remains open until the state has become 'reconnected'. The client will get only reconnected when the server invokes a subscription method on the client. So I am literally dependent of the server to call a method on my client side before I can close any connection.

Steps to reproduce:

1. start a connection with longpolling transport
2. create a hub proxy
3. wait until the connection gets in reconnect mode
4. perform some actions from the client to the server (which succeeds, while the connector says it isn't connected).
5. close the connection from the client
6. note that the connection doesn't disconnect
7. try to invoke a client method from the server
8. client gets reconnected and disconnected immediately.

Maven

It would be nice if the jars were published to maven. This would make it significantly easier to consume and get updates from this library.

Android SignalR java-client: Not receiving all the SignalR messages on the HubConnection

I've tried to receive the SignalR messages in several ways, but in any case I'm able to receive them always... I'm using the LongPollingTransport (maybe it is due to this), and I can see that the LongPolling log receives all the messages correctly but it only enters the handler method sometimes (in the others it seems to try to reconnect the server).

You can see more details on the StackOverflow question here: http://stackoverflow.com/questions/28587391/android-signalr-java-client-not-receiving-all-the-signalr-messages-on-the-hubco

I would really appreciate your help, because I'm are trying to move from SignalA (over a year without updates + some internal errors unhandled) to this library but at the moment I'm not able to receive all the messages, so I can't do it.

Many thanks!
