- Stage-Alpha summary: "Authenticate users against an external HTTP API" ...
Overview
This authentication module allows Prosody to authenticate users against an external HTTP service.
Configuration
VirtualHost "example.com"
authentication = "http"
http_auth_url = "http://example.com/auth"
If the API requires Prosody to authenticate, you can provide static credentials using HTTP Basic authentication, like so:
http_auth_credentials = "prosody:secret-password"
Developers
This section contains information for developers who wish to implement a HTTP service that Prosody can use for authentication.
Protocol
Prosody will make a HTTP request to the configured API URL with an
appended /METHOD
where METHOD
is one of the methods described below.
GET methods must expect a series of URL-encoded query parameters, while
POST requests will receive an URL-encoded form (i.e.
application/x-www-form-urlencoded
).
Parameters
- user
- The username, e.g.
stephanie
for the JIDstephanie@example.com
. - server
- The host part of the user's JID, e.g.
example.com
for the JIDstephanie@example.com
. - pass
- For methods that verify or set a user's password, the password will be supplied in this parameter, otherwise it is not set.
Methods
The only mandatory methods that the service must implement are check_password
and user_exists
. Unsupported methods should return a HTTP status code
of 501 Not Implemented
, but other error codes will also be handled by
Prosody.
Method HTTP method Success codes Error codes Response
register POST 201 409 (user exists)
check_password GET 200 A text string of true
if the user exists, or false
otherwise.
user_exists GET 200 A text string of true
if the user exists, or false
otherwise.
set_password POST 200, 201 or 204
remove_user POST 200, 201 or 204
Examples
With the following configuration:
authentication = "http"
http_auth_url = "https://auth.example.net/api"
If a user connects and tries to log in to Prosody as "romeo@example.net"
with the password "iheartjuliet", Prosody would make the following HTTP
request:
https://auth.example.net/api/check_password?user=romeo&server=example.net&pass=iheartjuliet
# Compatibility
Requires Prosody 0.11.0 or later.
