I need an example of how to Broadcast same message to multiple receivers using EasyNetQ library

rabbitmq fanout exchange java example
easynetq unsubscribe

I am trying to use EasyNetQ to send and receive messages from RabbitMQ, I need to send same message to multiple receivers or whom ever is connected at the time.

I have tried publish-subscribe messaging pattern and it works fine, but it's more like round-robin, where once the message is received by a receiver it's removed from the queue and nobody else can see the message.

Here's my message sender.

        for (int i = 0; i < 10; i++)
        {
            using (IBus bus = RabbitHutch.CreateBus(Host))
            {
                bus.Publish(new TextMessage { Text = $"{i}: Hello World from EasyNetQ" }, "dashboard");
            }
        }

Here's my receiver.

public void GetMessages() {

        using (IBus bus = RabbitHutch.CreateBus(Host))
        {
            bus.Subscribe<TextMessage>("dashboard", HandleTextMessage);

            Console.WriteLine("Listening for messages. Hit <return> to quit.");
            Console.ReadLine();
        }
    }

    static void HandleTextMessage(TextMessage textMessage)
    {
        Console.ForegroundColor = ConsoleColor.Red;
        Console.WriteLine("Got message: {0}", textMessage.Text);
        Console.ResetColor();
    }

Once a message is received no other receiver can see that message and I need all of the connected receivers see the same message.

Actually EasyNetQ will abstract you from having to deal with exchanges in most cases. To achieve what you ask simply specify a different subscription Id when subscribing, for instace a GUID:

public void GetMessages() 
{

    using (IBus bus = RabbitHutch.CreateBus(Host))
    {
        bus.Subscribe<TextMessage>(Guid.NewGuid().ToString(), HandleTextMessage);

        Console.WriteLine("Listening for messages. Hit <return> to quit.");
        Console.ReadLine();
    }
}

static void HandleTextMessage(TextMessage textMessage)
{
    Console.ForegroundColor = ConsoleColor.Red;
    Console.WriteLine("Got message: {0}", textMessage.Text);
    Console.ResetColor();
}

I believe the question describes the behavior of a fanout exchange. They aren't widely used, but it's clear that is what you are looking for. More information can be found here: https://www.tutlane.com/tutorial/rabbitmq/csharp-rabbitmq-fanout-exchange

RabbitMQ tutorial, As with other Python tutorials, we will use the Pika RabbitMQ client version In this part we'll do something completely different -- we'll deliver a message to multiple Essentially, published log messages are going to be broadcast to all the receivers. Firstly, whenever we connect to Rabbit we need a fresh, empty queue. Broadcast receivers are the handlers for receiving and processing push notifications sent to an android device. Setting up a single broadcast receiver to handle push notifications to your app is a straightforward process.

I did not understand how RabbitMQ works. All I needed was to create an Exchange and have Exchange send the messages to the queues. I though Queues did that.

Consumer Acknowledgements and Publisher Confirms, This guide covers the features in AMQP 0-9-1 but the idea is largely the same in When RabbitMQ delivers a message to a consumer, it needs to know when to Client library methods that acknowledge deliveries take a delivery tag as an Here's a Java client examples that demonstrates a positive acknowledgement: The examples included use the library for specific goals. The first one is a Wpf LAN chat and the second one is a Forms LAN game called Sink the Boat . The chat is quite the same as the above console example but translated into very basic Wpf code.

Working with RabbitMQ exchanges and publishing messages from , How Topic Exchanges Route Messages; Topic Exchange Routing Example; Topic There are multiple exchange types in the AMQP 0.9.1 specification, each with its own AMQP message attributes are metadata and are similar in purpose to HTTP Fanout exchanges are ideal for the broadcast routing of messages. You just need to create a class which extends the BroadcastReceiver abstract class and implement the onReceive method.This method is triggered when the receiver receives a broadcast and its comes in with two parameters- Intent object and Context. Intent can be used to get any additional information passed along with the broadcast.

No. Most receivers have the same input impedance - about 50 ohms so you would only need one tuner. The tuner resonates the antenna at some frequency of

EasyNetQ, This library is a pure PHP implementation of the AMQP protocol. But when you have a message queue like RabbitMQ, then that message queue is 15below dramatically simplified their application architecture with EasyNetQ and RabbitMQ. Batch publish allows sending multiple messages in one stream on the socket. Broadcast Receivers simply respond to broadcast messages from other applications or from the system itself.These messages are sometime called events or intents. For example, applications can also initiate broadcasts to let other applications know that some data has been downloaded to the device and is available for them to use, so this is broadcast receiver who will intercept this

  • Yes this is what I am looking for, but I was wondering if there's the same ability in EasyNetQ Client?
