Details
scgi_server is a daemon to speed up execution of CGI programs using the SCGI protocol, which is similar to FastCGI.
Both are designed to speed up programs executed by a Webserver by loading the CGI once when the server is started.
This avoids the loading of dependencies, compilation, execution and initialisation overhead per click, since it just happens
once at server startup. HTTP requests just call an already loaded dispatcher function. The CGI behaves like a Webserver.
While other solutions are more flexible scgi_server just supports one port (default Port-8187-tcp), one scripting language (Lua)
and one single script (default api.lua). This script must provide 2 functions to work:
cgi_load_callback- called once when the server is startedcgi_start_callback- called for each incoming HTTP request
AVM uses SCGI to speed up the new REST-API which consists of a range of RESTAPI-Scripts served via HTTP on Port-8187-tcp.
Currently it is only usable from localhost and IPv4, but it is prepared for usage from LAN and from the Internet. 7530 fw 7.50:
root@fritz1:/var/media/ftp# netstat -tap | grep scgi_server tcp 0 0 localhost:8187 0.0.0.0:* LISTEN 925/scgi_server
The REST-API uses normal HTTP and the request methods GET, POST, PUT and DELETE. The request URL is construted like this:
http://localhost:8187/api/v0/<endpoint>[/<string>[/<string>[/<string>]]]?sid=<sid>[&<arg>=<val>]
The API still is unfinished that's why its version is v0. An <endpoint> is a function block for a specific topic.
In current implementation the request URI can have up to 3 <string> levels.
Access requires a session id which is passed in <sid>, same principle as used for the Webinterface.
Since the API is mainly used from withing Lua-Scripts of the Webinterface the <sid> is just forwarded.
An <endpoint> can either be a builtin of api.lua or an <endpoint>_rest.lua module.
Besides this a selected subset of UI-Modules is accessible as <endpoint>s.
The API has a sophisticated security management. Each <endpoint> can have different access requirements.
Permissions are inherited from the Box-Users management, results appear in the rights ui-module for the current <sid>.
By default an <endpoint> is denied, and whitelisted by a per <endpoint> access mask assigned in security.lua.
This mask may be one or more of App, BoxAdmin, Dial, HomeAuto. NAS, Phone, as known from the Box-Users.

Lua-Land
The REST-API consists of a range of Lua-Scripts located in /usr/rest_api. AVM calls it Lua-Land.
The main script which is loaded by the server is api.lua. The remaining scripts are loaded by dependency.
See the RESTAPI-Scripts section.
