#summary HTTP access to prosody’s storage mechanism

= Introduction =

This module gives HTTP access to prosody’s storage mechanism.  It uses normal HTTP verbs and [http://tools.ietf.org/html/rfc2617 Basic HTTP authentication], so you could call it RESTful if you like buzzwords.

= Syntax =

To Fetch data, issue a normal GET request
{{{
	GET /data[/<host>/<user>]/<store>[/<format>] HTTP/1.1
	Authorization: <base64(authzid:password)>
	[Host: <host>]

	-- OR --

	PUT|POST /data[/<host>/<user>]/<store>[/<format>] HTTP/1.1
	Content-Type: text/x-lua | application/json

	<data>
}}}

These map to `datamanager.method(user, host, store, data)`, where choice of `method` and its parameters are explained below.

== Verbs ==

||*Verb*||*Meaning*                      ||*datamanager method*        ||
||`GET` || Just fetch data               || `load()` or `list_load()`  ||
||`PUT` || Replace all data in the store || `store()                   ||
||`POST`|| Append item to the store      || `list_append()`            ||

Note: In a `GET` request, if `load()` returns `nil`, `list_load()` will be tried instead.

== Fields ==

||*Field*||*Description*||*Default*||
||`host`||Which virtual host to access||Required. If not set in the path, the `Host` header is used. If that's not set either, the domain-part of the authzid is used.||
||`user`||Which users storage to access||Required. If not set in the path, uses the node part of the authzid.||
||`store`||Which storage to access.||Required.||
||`format`||Which format to serialize to. `json` and `lua` are supported. When uploading data, the `Content-Type` header is used.||`json`||
