mod_muc_rtbl: also filter messages This was a bit tricky because we don't want to run the JIDs through SHA256 on each message. Took a while to come up with this simple plan of just caching the SHA256 of the JIDs on the occupants. This will leave some dirt in the occupants after unloading the module, but that should be ok; once they cycle the room, the hashes will be gone. This is direly needed, otherwise, there is a tight race between the moderation activities and the actors joining the room.

summary: 'Receives HTTP POST request, parses it and relays it into XMPP.'
---

Introduction
============

Sometimes it's useful to have different interfaces to access XMPP.

This module allows sending XMPP
[`<message>`](https://xmpp.org/rfcs/rfc6121.html#message) stanzas via a
simple HTTP API.

Example usage
-------------

    curl http://example.com:5280/msg/user -u me@example.com:mypassword -H "Content-Type: text/plain" -d "Server@host has just crashed!"

This would send a message to user\@example.com from me\@example.com

Details
=======

URL format
----------

    /msg/ [recipient [@host] ].

The base URL defaults to `/msg`. This can be configured via Prosodys
[HTTP path settings][doc:http].

Authentication
--------------

Authentication is done by HTTP Basic.

    Authentication: Basic BASE64( "username@virtualhost:password" )

Payload formats
---------------

Supported formats are:

`text/plain`
:   The HTTP body is used as plain text message payload, in the `<body>`
    element.

`application/x-www-form-urlencoded`
:   Allows more fields to be specified.

`application/json`
:   Similar to form data.

Which one is selected via the `Content-Type` HTTP header.

### Data fields

The form data and JSON formats allow the following fields:

`to`
:   Can be used instead of having the receiver in the URL.

`type`
:   [Message type.](https://xmpp.org/rfcs/rfc6121.html#message-syntax-type)

`body`
:   Plain text message payload which goes in the `<body>` element.
