RabbitMQ

RabbitMQ is an open-source message-broker software that originally implemented the Advanced Message Queuing Protocol and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol, Message Queuing Telemetry Transport, and other protocols.

RabbitMQ can be used in CAP as a message transporter.

Configuration

To use RabbitMQ transporter, you need to install the following package from NuGet:

PM> Install-Package DotNetCore.CAP.RabbitMQ

Next, add configuration items to the ConfigureServices method of Startup.cs.

public void ConfigureServices(IServiceCollection services)
{
    // ...

    services.AddCap(x =>
    {
        x.UseRabbitMQ(opt=>
        {
            //RabbitMQOptions
        });
        // x.UseXXX ...
    });
}

RabbitMQ Options

The RabbitMQ configuration parameters provided directly by CAP:

NAME	DESCRIPTION	TYPE	DEFAULT
HostName	Broker host address	string	localhost
UserName	Broker user name	string	guest
Password	Broker password	string	guest
VirtualHost	Broker virtual host	string	/
Port	Port	int	-1
TopicExchangeName	Default exchange name of cap created	string	cap.default.topic
QueueMessageExpires	Message expries after to delete, in milliseconds	int	(10 days) milliseconds

ConnectionFactory Options

If you need more native ConnectionFactory configuration options, you can set it by ‘ConnectionFactoryOptions’ option:

services.AddCap(x =>
{
    x.UseRabbitMQ(o =>
    {
        o.HostName = "localhost";
        o.ConnectionFactoryOptions = opt => { 
            //rabbitmq client ConnectionFactory config
        };
    });
});

How to connect cluster

using comma split connection string, like this:

x=> x.UseRabbitMQ("localhost:5672,localhost:5673,localhost:5674")
