System.IO.InvalidDataException: Missing required property 'protocol' and System.IO.InvalidDataException: Missing required property 'type' when using Java client #23291
Description
Describe the bug
A clear and concise description of what the bug is.
When I use Java client, it's easy to get 2 kinds of error on server:
Missing required property 'protocol'. and System.IO.InvalidDataException: Missing required property 'type'.
To Reproduce
Use this code to start/stop clients:
import com.microsoft.signalr.HubConnection;
import com.microsoft.signalr.HubConnectionBuilder;
import io.reactivex.Single;
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;
public class Chat {
public static HubConnection create(boolean service)
{
if (service) {
HubConnection hubConnection = HubConnectionBuilder
// .create("http://localhost:5000/chat")
.create("http://localhost:8080/client/?hub=hub")
.withAccessTokenProvider(Single.defer(() -> {
return Single.just("...");
}))
.build();
return hubConnection;
} else {
HubConnection hubConnection = HubConnectionBuilder
.create("http://localhost:5000/chat")
.build();
return hubConnection;
}
}
public static void main(String[] args) throws Exception {
ThreadPoolExecutor executor = new ThreadPoolExecutor(100, 200, 300,
TimeUnit.MILLISECONDS, new ArrayBlockingQueue<Runnable>(3),
new ThreadPoolExecutor.CallerRunsPolicy());
HubConnection hubConnection = create(false);
for(int i=0;i<10;i++) start(executor, hubConnection);
for(int i=0;i<10;i++) stop(executor, hubConnection);
}
public static void stop(ThreadPoolExecutor executor, HubConnection hubConnection) {
executor.execute(() -> {
while (true) {
try {
hubConnection.stop();
Thread.sleep((int) (Math.random() * 500));
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public static void start(ThreadPoolExecutor executor, HubConnection hubConnection) {
executor.execute(() -> {
while (true) {
try {
hubConnection.start();
Thread.sleep((int) (Math.random() * 50));
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
}
