初始化Rabbit服务（代码方式）

 services.AddRabbitMqClient(new RabbitMqClientOptions
 {
     HostName = "192.168.7.66",
     Port = 5672,
     Password = "guest",
     UserName = "guest",
     VirtualHost= "/",
 })
 .AddProductionExchange("LeonTest", new RabbitMqExchangeOptions
     {
         DeadLetterExchange = "DeadExchange", //不为空，默认不重发
         AutoDelete = false,
         Type = "fanout",
         Durable = true,
         Queues = new List<RabbitMqQueueOptions> { new RabbitMqQueueOptions { AutoDelete = false, Exclusive = false, Durable = true, Name = "myqueue", RoutingKeys = new HashSet<string> { "mini", "yang" } } }
     })
     .AddConsumptionExchange($"{LeonTest}", new RabbitMqExchangeOptions
            {
                DeadLetterExchange = "DeadExchange", //不为空，默认不重发
                AutoDelete = false,
                Type = ExchangeType.Direct,
                Durable = true,
                Queues = new List<RabbitMqQueueOptions> { new RabbitMqQueueOptions { AutoDelete = false, Exclusive = false, Durable = true, Name = $"{myqueue}", RoutingKeys = new HashSet<string> { "myqueue" } } }
            }).AddMessageHandlerSingleton<CustomMessageHandler>("myqueue");

            services.BuildServiceProvider().GetRequiredService<IQueueService>().StartConsuming();;

生产消息

namespace MQ.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
    public class ValuesController : ControllerBase
    {
        private readonly IQueueService _queueService;
        public ValuesController(IQueueService queueService)
        {
            _queueService = queueService;
        }
        // GET api/values
        [HttpGet]
        [Route("Send")]
        public ActionResult<IEnumerable<string>> Send(string mes)
        {
            _queueService.Send(//发送消息
                                @object: $"{mes}",
                                exchangeName: "LeonTest",
                                routingKey: "yang"
                                 );
            return new string[] { "value1", "value2" };
        }
    }
}
 }

消费消息

namespace ReceiveB.Service
{
    //继承IMessageHandler，即可作为消费者消费消息
    public class CustomMessageHandler : IMessageHandler
    {
         private readonly IServiceScopeFactory _serviceScopeFactory;
        readonly ILogger<CustomMessageHandler> _logger;
        public CustomMessageHandler(ILogger<CustomMessageHandler> logger,
          IServiceScopeFactory serviceScopeFactory)
        {
            //由于消费者在BuildServiceProvider()之前就执行导致对象还没注入，所以此处不支持自定义类型的实例注入，只能通过IServiceScopeFactory来获取servcie实例
            _logger = logger;
            _serviceScopeFactory = serviceScopeFactory;
        }

        public void Handle(string message, string routingKey)
        {
            using var scope = _serviceScopeFactory.CreateScope();
            var _redisOptionService = scope.ServiceProvider.GetRequiredService<IRedisOptionService>();

            Console.WriteLine($"正在消费消息");
            _logger.LogInformation("");
        }
    }
}
