mod_data_access

Introduction

This module gives HTTP access to prosody’s storage mechanism. It uses normal HTTP verbs and 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)>

OR

PUT|POST /data[/<host>/<user>]/<store> 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()

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