title: How to publish byte array to the queue by using RabbitMQ management plugin?
body: <p>As shown below, RabbitMQ management GUI can publish a message to the specific queue directly.<a href="https://i.stack.imgur.com/Wkczu.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Wkczu.png" alt="enter image description here"></a></p>
  
  <p>The consumer of this queue consumes the message with protobuf format, which means I should publish the byte array to the queue instead of string. I have tried to convert the protobuf bytes into a base64 string but failed, is possible to tell the RabbitMQ Management GUI to convert the base64 string into bytes or there is another way to publish byte array directly?</p>
