A RESTful admin interface to Prosody XMPP server.

There are a few ways to administer Prosody; by using either the mod_admin_telnet, mod_admin_adhoc, or via prosodyctl. mod_admin_rest seeks to enable a more programmatic interface to Prosody commands that exist in the stock admin modules, and some commands that don't.

• Compatible with v0.9. Not tested and likely incompatible with previous versions.
• It's highly advisable to install lua-cjson. mod_admin_rest will use it if it is available.

1. Place mod_admin_rest.lua in your plugins directory.
2. Add admin_rest to modules_enabled list of your prosody.cfg.lua
3. Start or restart Prosody

This module depends on Prosody's http module, so it inherits the http module's configuration. You do not need to add http to the enabled modules list; it is loaded automatically. By default, http server listens on port 5280. All requests must contain Basic authentication for a user who has administrative privileges. HTTP Basic access authentication is one of the easiest authentication methods and it's only safe with a secure SSL/HTTPS connection. The header generated is: ("Authorization" is the Headerfieldname and "Basic {TOKEN}" the Value.)

Authorization: Basic {TOKEN}

where the {TOKEN} is the base 64 of the username and password separated by a colon. In pseudo-code, it would be:

base64(username + ':' + password)

Requests with bodies must contain Content-Type and Content-Length headers. Additionally, some admin_rest commands may require request bodies. mod_admin_rest attempts to make appropriate use of HTTP status codes and request methods. Request paths have the following general structure:

/admin_rest/operation/resource/attribute

Responses are JSON-encoded objects with a result property. They have the form:

{ result: { ... } }

A handful of useful commands are supported. More will come in the future.

If the user does not exist, response status code is 404. Otherwise 200. If a user is offline, response will contain connected=false and empty roster/session lists.

GET /admin_rest/user/username

{
  user: {
    connected: true,
    sessions: [ ... ],
    roster: [ ... ]
  }
}

Each session item in the sessions list has the following structure:

{
  resource: "",
  secure: true,
  port: 1337,
  ip: 127.0.0.1,
  id: "f8fhfw3"
}

Status codes

• 200 User connected, successful
• 404 User does not exist or not connected

Unlike get user, this will not respond with stringified user content, which can be quite verbose as it contains session data. This command will respond with a 200 status code if the user is connected.

GET /admin_rest/username/connected

Response:

{ connected: true }

Status codes

• 200 User connected
• 404 User not connected

If command complete successfully, an array of user objects is returned, with status code 200. If no users are connected, an empty object is returned.

GET /admin_rest/users

{
  count: count,
  users: {
    [ { username, resource }, ... ]
  }
}

Get just the count of connected users.

GET /admin_rest/users/count

{
  count: count
}

Add a user. If the user exists, response status code is 409. If a user is successfully created, 201.

POST /admin_rest/user/username

Include password in the request body

{ password: "mypassword",
  regip: "ipadress"
 }

regip is optional.

Status codes

• 201 User created
• 409 User already exists

Removes a user. If the user does not exist, response status code is 404. If a user is successfully removed, 200.

DELETE /admin_rest/user/username

Status codes

• 200 User deleted
• 404 User does not exist

The only implemented attribute for now is password. Ultimately roster modifications may be implemented. Supply values for attributes in the request body as encoded JSON:

PATCH /admin_rest/user/username/attribute

{ attribute: value }

Example: For changing a user's password. Assuming user's name is testuser

PATCH /admin_rest/user/testuser/password

With request body:

{ password: "mypassword" }

Status codes

• 200 User was updated successfully
• 400 Invalid modification
• 404 User does not exist

If a user was updated successfully, response status code is 200. If a user does not exist, response status code is 404.

Get the rosters of the user. If command complete successfully, an array of roster objects is returned, with status code 200. If no roster, an empty object is returned.

Get /admin_rest/roster/username

{
  count: count,
  roster: {
    [["item",{"jid":"jid1","subscription":"both","group":["group1"]}], ... ]
  }
}

Status codes

• 200 Get roster

Add a roster to a user. If the contact user does not exist, response status code is 404. If a user is successfully removed, 200.

Add /admin_rest/roster/username

With request body:

{ contact: "roster jid" }

Status codes

• 200 Roster added
• 404 Contact does not exist or is malformed

Removes a roster from a user. If the contact user does not exist, response status code is 404. If a user is successfully removed, 200.

DELETE /admin_rest/roster/username

With request body:

{ contact: "roster jid" }

Status codes

• 200 Roster deleted
• 404 Contact does not exist or is malformed

Send a message to a particular user on a particular host. Messages are sent from the hostname. Include the content of your message in a JSON-encoded request body.

POST /admin_rest/message/username

{ message: "My message" }

Status codes

• 200 Message sent
• 202 Message delayed (sent to offline queue)
• 404 User does not exist

Send bulk messages to a number of particular users. Request body should contain an array of JSON objects, each with a to and message attribute.

POST /admin_rest/message

{
  [
    { to: "testuser", message: "My message" },
    ...
  ]
}

If any messages were multicasted, response status code is 200, and response body has the following form, where s is the number of messages sent, and d is the number of messages delayed (to be sent to offline queue).

  {
    result: "Message multicasted to users: s/d"
  }

Status codes

• 200 Message sent
• 404 No messages were sent; no valid recipients were found

Send a message to every connected user using a particular host. Messages are sent from the hostname. Include the content of your message in a JSON-encoded request body.

POST /admin_rest/broadcast

{ message: "My message" }

In the response body is a count of the number of users who were sent the message. Example response:

{ count: 100 }

Status codes

200 Broadcast successful

Returns the name and loaded state of provided module. Successful response status code is 200.

GET /admin_rest/module/modulename

Response has the following form:

{
  module: "mymodule",
  loaded: true
}

Status codes

• 200 Module is loaded
• 404 Module is not loaded

List loaded modules for a particular host. Successful response status code is 200.

GET /admin_rest/modules

Sample response:

{
  count: 5,
  modules: [
    "ping",
    "dialback",
    "presence",
    "s2s",
    "message"
  ]
}

Status codes

• 200 Modules listed

Load or reload a module. Successful response status code is 200.

PUT /admin_rest/module/modulename

Status codes

• 200 Module loaded

Unload a module. Successful response status code is 200. If a module is not loaded, 404.

DELETE /admin_rest/module/modulename

Status codes

• 200 Module unloaded

Returns array of whitelisted as per admin_rest_whitelist configuration. Returns an empty object if no whitelist configuration exists.

GET /admin_rest/whitelist

An example response body:

{
  whitelist: [ "127.0.0.1", ... ],
  count: 1
}

Add a provided IP to whitelist.

PUT /admin_rest/whitelist/ip

Status codes

• 200 Added to whitelist

Remove a provided IP from whitelist.

DELETE /admin_rest/whitelist/ip

Status codes

• 200 Removed from whitelist

Add any of the following options to your prosody.cfg.lua. You may forward additional HTTP options to Prosody's http module.

admin_rest_secure boolean

Whether incoming connections must be secure. Default is false.

admin_rest_secure = false;

admin_rest_base string

Base path. Default paths begin with /admin_rest.

admin_rest_base = "/admin_rest";

admin_rest_whitelist array

List of IP addresses to whitelist. Only these IP addresses will be allowed to issue commands over HTTP.

admin_rest_whitelist = {
  "127.0.0.1"
};

If you modify the whitelist while Prosody is running, you will need to reload admin_rest module. One way you can do this is by connecting to admin_telnet service which runs by default on port 5582.

$ echo "module:reload('admin_rest', <host>)" | nc localhost 5582

Alternatively, you may use admin_rest to reload itself by issuing a load request to itself. Example:

PUT /admin_rest/module/admin_rest

Better still, you may use admin_rest itself to add or remove IPs from whitelist while in operation.

admin_rest_message_prefix string

admin_rest_multicast_prefix string

admin_rest_broadcast_prefix string

Optional message prefixes
