用c#从RabbitMQ的队列中获取所有消息

Question

Given the queue name, i need all the messages in that queue in RabbitMQ.

I have got the number of messages in the queue in msgCount variable and the first message in strBody variable. But i need all the messages in the given queue. Something that the RabbitMQ Management UI gives me in the browser when i click the Get Message(s) button

using (var conn = _connectionFactory.CreateConnection())
        {
            using (var channel = conn.CreateModel())
            {
                var queueName = "myqueuename";

                var response = channel.QueueDeclarePassive(queueName);
                var msgCount = response.MessageCount;
                var consCount = response.ConsumerCount;

                BasicGetResult result = channel.BasicGet(queueName, noAck);


                if (result == null)
                {
                    //No msgs available 
                }
                else
                {
                    IBasicProperties properties = result.BasicProperties;
                    byte[] body = result.Body;

                    string strBody = System.Text.Encoding.UTF8.GetString(body);
                    Console.WriteLine(strBody);
                    //channel.BasicAck(result.DeliveryTag, false);
                }
            }
        }

Making a simple http request to the rabbitMQ server does the job. Make a POST request to the following url:

string queuesUrl = Url + ":" + Port + "/api/queues/" + VirtualHost + "/" + queueName + "/get";

where Url is where your rabbitMQ is hosted

Send the following payload

{"count":5,"ackmode":"ack_requeue_true","encoding":"auto","truncate":50000}

Put -1 in count to get all the messages. Truncate is optional
