ejabberd API library and command-line tool

This tool is composed of two components:

• A command-line tool to interact with ejabberd through ReST API calls from the command-line, from any server type or desktop (Linux, OSX, Windows).
• An implementation of ejabberd API client library in Go. It can be used to interact with ejabberd from backend applications developed in Go programming language.

Installation

Both the library and the command-line tool can be installed from source with go get tool.

If you have go installed in your environment you can install ejabberd command-line tool with:

go get -u github.com/processone/ejabberd-api

Configuring ejabberd OAuth API

Before being able to interact with ejabberd API, you need to configure ejabberd with OAuth support enabled. This is is documented in ejabberd OAuth support.

Here are example entries to check / change in your ejabberd configuration file:

1. Add a listener for OAuth and ReST API:

   listen:
     -
       # Using a separate port for oauth and API to make it easy to protect it
       # differently than BOSH and Websocket HTTP interface.
       port: 5281
       # oauth and API only listen on localhost interface for security reason
       # You can set ip to "0.0.0.0" to open it widely, but be careful!
       ip: "127.0.0.1"
       module: ejabberd_http
       request_handlers:
         "/oauth": ejabberd_oauth
         "/api": mod_http_api

2. You can then configure the OAuth commands you want to expose. Check commands_admin_access to make sure ACL for passing commands as admins are set properly:

   commands_admin_access:
     - allow:
       - user: "admin@localhost"
   commands:
     - add_commands: ['ejabberd:user', user, admin, open]
   oauth_expire: 32000000
   oauth_access: all

3. Finally, make sure the modules, you need to use the command from are enabled, for example:

   modules:
     mod_admin_extra: {}

ejabberd command-line tool

ejabberd command-line tool allow interacting ejabberd with ejabberd ReST API. It relies on OAuth tokens and scope to define the command the user will be allowed to call.

Usage

1. Generating an OAuth token:

To use ejabberd command-line tool, you first need to generate an OAuth token.

It can be done, for example, with the following command:

ejabberd token -j admin@localhost -p mypassword -s ejabberd:admin

This will generate a .ejabberd-oauth.json file containing your credentials. Keep the file secret, as it will grant access to command available in the requested scope on your behalf.

2. Calling ejabberd API from the command-line, using your token file. For example:

ejabberd stats registeredusers

Generating Bash/ZSH completion

You can generate Bash completion with following command:

./ejabberd --completion-script-bash

You can generate ZSH completion with following command:

./ejabberd --completion-script-zsh

To be able to use completion for Bash, you can type or add in your bash_profile (or equivalent):

eval "$(ejabberd --completion-script-bash)"

For ZSH, you can use:

eval "$(ejabberd --completion-script-zsh)"

Available commands

• token: Get OAuth token. This is needed before calling others commands.
• stats: Retrieve some stats from ejabberd.
