如何在Rabbitmq Go中发布和使用make（map [string] string）

Question

I have multiple objects of key-value type which i need to send to RabbitMQ and hence forward would consume them. So, after going through this RabbitMQ link. It only tells the way to publish a simple plain text message. Can anyone tell me how to publish and consume map objects in RabbitMQ go lang?

     m := make(map[string]string)
     m["col1"] = "004999010640000"
     m["col2"] = "awadwaw"
     m["col3"] = "13"  

     err = ch.Publish(
        "EventCaptureData-Exchange", // exchange
        q.Name + "Key",          // routing key
        true,           // mandatory                            
        false,           // immediate
        amqp.Publishing{
            ContentType: "?????",
            Body:        ????,
        })

You need to serialize your Go object to eg. base64 text before publishing it. In your consumer, you then deserialize it to get back your initial object. See "Golang serialize and deserialize back" for an example in Go.

For the content type, I'm not sure what is the most appropriate. application/octet-stream?
