Publishing to the default rabbitmq exchange using the http api
Solution 1
This is the way to publish a message to amq.default
:
http://localhost:15672/api/exchanges/%2f/amq.default/publish
with this body
{"properties":{},
"routing_key":"queue_test",
"payload":"message test ",
"payload_encoding":"string"}
routing_key
is the queue where you will publish the message.
Following an example using a chrome plug-in:
Solution 2
Here is curl to publish Message:
curl -4vvv -u admin:admin \
'localhost:15672/api/exchanges/%2F/amq.default/publish' \
-H 'Content-Type: text/plain;charset=UTF-8' \
--data-binary '{"vhost":"/","name":"amq.default","properties":{"delivery_mode":1,"headers":{}},"routing_key":"MY-QUEUE-NAME","delivery_mode":"1","payload":"TEST","headers":{},"props":{},"payload_encoding":"string"}'
My Sample Request:
Username: admin
Password: admin
Routing Key: sample.load.work
(My queue)
curl --location --request POST 'localhost:15672/api/exchanges/%2F/amq.default/publish' \
--header 'Content-Type: text/plain;charset=UTF-8' \
--header 'Authorization: Basic YWRtaW46YWRtaW4=' \
--data-raw '{"vhost":"/","name":"amq.default","properties":{"delivery_mode":1,"headers":{}},"routing_key":"sample.load.work","delivery_mode":"1","payload":"TEST","headers":{},"props":{},"payload_encoding":"string"}'

So I am using rabbitmqs http api to do some very basic actions in rabbit. It works great in most situations but I am having an issue figuring out how to use it to publish a message to the default rabbitmq exchange. This exchange is always present, cannot be deleted and has a binding to every queue with a routing key equal to the queue name.
My problem is that this queue does not have a name, or rather, it's name is an empty string "". And the URL I have to use to publish this message with the HTTP api includes the name of the exchange.
http://localhost:15672/api/exchanges/vhost/name/publish (Source: http://hg.rabbitmq.com/rabbitmq-management/raw-file/rabbitmq_v3_3_4/priv/www/api/index.html)
The same article mentions that in order to use the default vhost which has a name of "/", you must use %2f in place of the vhost name. This makes me think there should be a similar way to represent the deafault exchange in the url.
I tried a few different things and none of them worked:
/api/exchanges/vhost//publish /api/exchanges/vhost/""/publish /api/exchanges/vhost/''/publish /api/exchanges/vhost/ /publish /api/exchanges/vhost/%00/publish
I'm sure I can't be the only person that has run into this issue. any help would be much appreciated.
thanks, Tom
