Unable to get, post or update queue metadata

[Neerja Narayan]

Environment : wsgi , mongodb

Requesting queue metadata:

How do we make a request to just know the queue metadata like in v1?
Is /metadata deprecated?
If its deprecated then is it not completely removed from v1_1 and v2 ?
Sorry too many questions! :)

Posting queue metadata :

Scenario1 : Queue is create with metadata ==> 201 Created
Scenario2 : Queue is created without metadata ==> 201 Created
                     Now using the same queue , adding metadata in the request ==>204 No content , but no metadata gets added to the queue

curl -i -X PUT http://IP:8888/v2/queues/queue_name -H "X-Auth-Token: $TOKEN" -H "Content-type: application/json" -H "Client-ID: $CLIENT_ID"

HTTP/1.0 201 Created

curl -i -X PUT http://IP:8888/v2/queues/queue_name -H "X-Auth-Token: $TOKEN" -H "Content-type: application/json" -H "Client-ID: $CLIENT_ID" -d '{"metadata": "My Queue"}'

HTTP/1.0 204 No Content

Updating queue metadata

curl -i -X PUT http://IP:8888/v2/queues/queue_name -H "X-Auth-Token: $TOKEN" -H "Content-type: application/json" -H "Client-ID: $CLIENT_ID" -d '{"metadata": "My Queue"}'

HTTP/1.0 204 No Content

curl -i -X GET http://10.20.33.5:8888/v2/queues/neerja -H "X-Auth-Token: 7e489cf5881b4afeb0fc9cbaba3772c2" -H "Content-type: application/json" -H "Client-ID: de305d54-75b4-431b-adb2-eb6b9e546014"

PUT meas to create a queue.
And you should use PATCH in v2 to update the queue's metadata: https://review.openstack.org/#/c/292843/

I have a client patch to add the update metadata command : https://review.openstack.org/#/c/294368/
also a patch to fix some errors : https://review.openstack.org/#/c/305560/

the request should be like:
PATCH http://IP:8888/v2/queues/queue_name
the request body should be like:
[
  {
     "op":"add",
     "patch":"/metadata/type",
     "value":"test"
  }
]

then the queue's metadata will be like :{"_max_messages_post_size": 262144, "_default_message_ttl": 1209600, "type": "test"}

Hey wangxiyuan, thank you so much. I understood where I was going wrong. And I have a minor glitch in the following ,

curl -i -X PUT http://IP:8888/v2/queues/queue_name -H "X-Auth-Token: $TOKEN" -H "Content-type: application/json" -d '{"metadata": "My Queue"}' -H "Client-ID: $CLient_ID"

201 created.

 curl -i -X PATCH http://IP:8888/v2/queues/queue_name -H "X-Auth-Token: $TOKEN" -H "Content-type: application/json" -H "Accept: application/openstack-messaging-v2.0-json-patch" -d '[{"op":"add","patch":"/metadata/type","value":"test"}]' -H "Client-ID: $CLient_ID"

406 Not Acceptable

Any idea why so?

Thank you! :)

[wangxiyuan (wangxiyuan)]

curl -i -X PATCH http://IP:8888/v2/queues/queue_name -H "X-Auth-Token: $TOKEN" -H "Content-type: application/json" -H "Accept: application/openstack-messaging-v2.0-json-patch" -d '[{"op":"add","patch":"/metadata/type","value":"test"}]' -H "Client-ID: $CLient_ID"

So there are some errors in your PATCH request:
1. "Content-type" should be "application/openstack-messaging-v2.0-json-patch"
2. "Accept" should be "application/json"
3. the body should be "[{"op":"add","path":"/metadata/type","value":"test"}]" (sorry for my comment before. It should be "path", not "patch")
