   <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 Mustache[4] templates.  The code generator is written in
Python, and uses Pystache[5]. Pystache has no dependencies, and be
installed easily using pip. Code generation code lives in
rest-api-templates/.

The generated code reduces a lot of boilerplate when it comes to handling
HTTP requests. It also helps us have greater consistency in the REST API.

The structure of the generated code is:

 - res/stasis_http/resource_{resource}.h
   - For each operation in the resouce, a generated argument structure
     (holding the parsed arguments from the request) and function
     declarations (to implement in res/stasis_http/resource_{resource}.c)
 - res_stasis_http_{resource}.c
   - A set of \ref stasis_rest_callback functions, which glue the two
     together. They parse out path variables and request parameters to
     populate a specific \c_args which is passed to the specific request
     handler (in res/stasis_http/resource_{resource}.c)
   - A tree of \ref stasis_rest_handlers for routing requests to its
     \ref stasis_rest_callback

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
