问题:

I am getting 400 bad request error while calling "/api/get_roster" endpoint of ejabberd. I had kept "get_roster" in the scope while requesting the oauth token.

400 bad request error in ejabberd

I guess there is some issue with the permissions. Here is my configuration file:

https://www.dropbox.com/s/his89bx39qhvr1h/ejabberd2.yml?dl=0

I have tried to follow the official documentation. As per the API permission guide, I have also tried adding following properties:

api_permissions:
  - "Admin access":
    - who:
      - admin
    - what
      - "\*"
      - "!stop"

But there was no change. I have following questions:

What am I doing wrong here?
What are possible scopes?

回答1:

Your request should contain Authorization header as below:

curl -v -X POST -H "Authorization: Bearer <Oauth_token>" http://localhost:5280/api/get_roster -d '[]'

You can refer to this link for more details. If you are accessing as admin you can use commands_admin_access rule to provide access to api commands and specify the commands you want to access as follows:

commands:
  - add_commands:
    - get_roster
commands_admin_access: configure

You are using very old version of Ejabberd. Latest is 17.04 which has lots of changes in API permission framework from 16.01 . api_permission related configuration came in 16.12 version. Please refer this for more detail.
