   <pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch represents the first step toward adding a RESTful API to Asterisk.

The following is the file doc from res_stasis_http.c:

The API itself is documented using Swagger[1], a lightweight mechanism for
documenting RESTful API&#39;s using JSON. This allows us to use swagger-ui[2] to
provide executable documentation for the API, generate client bindings in
different languages[3], and generate a lot of the boilerplate code for
implementing the RESTful bindings. The API docs live in the rest-api/ directory.

The RESTful bindings are generated from the Swagger API docs using a set of
Cog.py[4] templates. Cog.py is extemely lightweight (maybe too lightweight), and
can be installed easily using pip. Template scripts live in the cog/ directory,
and the generated code lives in the res/stasis-http/ directory.

The structure of the generated code is:

 - A tree of stasis_rest_handlers which are used for request routing.
 - Prototypes for request handlers, and structures for passing arguments in
   the request handler.
 - A set of stasis_rest_callback functions, which glue the two
   together. They parse out path variables and request parameters to populate
   a specific *_args which is passed to the specific request handler.

The use of the generated *_args allows for greater type safety and reduced
boilerplate in the request handlers themselves.

The basic flow of an HTTP request is:

 - stasis_http_callback()
   1. Initial request validation
   2. Routes as either a doc request (stasis_http_get_docs) or API
      request (stasis_http_invoke)
      - stasis_http_invoke()
        1. Further request validation
        2. Routes the request through the tree of generated
           stasis_rest_handlers.
        3. Dispatch to the generated callback
           - stasis_http_*_cb
             1. Populate *_args struct with path and get params
             2. Invoke the request handler
   3. Validates and sends response
