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'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
