How to send JSON payload to RabbitMQ using the web plugin?

Question

I have a RabbitMQ 3.4.2 instance with a web management plugin installed.

When I push to the message {\'operationId\': 194} to the queue using Python\'s komb

Answer 1

You need to de-serialize the output.

import json
payload = json.loads(payload)
operation_id = payload['operationId']

In addition {'operationId': 194} is not valid JSON. Although it looks like you use double quotes in the screenshot, but make sure you replace the single quotes with double quotes.

Edit: So you are correct, kombu should handle this. Looking at the code it's likely that the header is case-sensitive. Change the properties header from Content-Type to content-type.

Answer 2

I had to use content_type instead of content-type (an underscore instead of a hyphen).

This is a pretty questionable design decision, because the standard everybody knows is content-type.
