#summary Token based JSON registration & verification servlet.
#labels Stage-Stable

= Introduction =

This module let's you activate a httpserver interface to handle data from webforms with POST and Base64 encoded JSON.

= Implementation Details =

Example Request format:

{{{
POST /your_register_base_url HTTP/1.1
Host: yourserveraddress.com:yourchoosenport
Content-Type: application/encoded
Content-Transfer-Encoding: base64

eyJ1c2VybmFtZSI6InVzZXJuYW1lb2ZjaG9pY2UiLCJwYXNzd29yZCI6InRoZXVzZXJwYXNzd29yZCIsImlwIjoidGhlcmVtb3RlYWRkcm9mdGhldXNlciIsIm1haWwiOiJ1c2VybWFpbEB1c2VybWFpbGRvbWFpbi50bGQiLCJhdXRoX3Rva2VuIjoieW91cmF1dGh0b2tlbm9mY2hvaWNlIn0=
}}}

Where the encoded content is this (example) JSON Array:

<code language="javascript">
{"username":"usernameofchoice","password":"theuserpassword","ip":"theremoteaddroftheuser","mail":"usermail@usermaildomain.tld","auth_token":"yourauthtokenofchoice"}
</code>

Your form implementation needs to pass *all* parameters, the auth_token is needed to prevent misuses, if the request is successfull the server will answer with status code 200 and with the body of the response containing the token which your web app can send via e-mail to the user to complete the registration.

The module for now stores a hash of the user's mail address to help slow down duplicated registrations.

It's strongly encouraged to have the web server communicate with the servlet via https.

= Usage =

Copy the module file into your prosody modules directory.
Add the module your vhost of choice modules_enabled.

Hint: pairing with mod_register_url is helpful, to allow server registrations only via your webform.

Optional configuration directives:
<code language="lua">
reg_servlet_base = "/base-path/" -- Base path of the plugin (default is register_account)
reg_servlet_secure = true -- Have the plugin only process requests on https (default is true)
reg_servlet_ttime = seconds -- Specifies the time (in seconds) between each request coming from the same remote address.
reg_servlet_bl = { "1.2.3.4", "4.3.2.1" } -- The ip addresses in this list will be blacklisted and will not be able to submit registrations.
reg_servlet_wl = { "1.2.3.4", "4.3.2.1" } -- The ip addresses in this list will be ignored by the throttling.
reg_servlet_filtered_mails = { ".*banneddomain.tld", ".*deamailprovider.tld" } -- allows filtering of mail addresses via Lua patterns.
</code>
