Fluent Example

import ...
config = FluentConfigurator()

@config.on(Method.GET).at('/')
def index(req: Request, srv: Server)
    return Response(200, 'OK')

config._host = '0.0.0.0'
config._port = 8000
server = Server(config, loglevel=LogLevel.CONSOLE)
with server as s:
    s.run()

Running the tests

python3 -m unittests discover tests/

Plaintext Config settings

1. rules Is a map with regular language

   • use square braces for any match (same as .*? in re)
   • type [name] inside braces to set named group
   • use match names in found path example:

     "/[day]-[n]/[month]/[year]" : "/pictures/[year]/[month]/[day]/[n].png
     

     query localhost:8000/27-me/09/2000 will display a photo /pictures/2000/09/27/me.png if exists

2. host Chose server host

   • use localhost to run locally

3. port Specify port for server to listen

   • default is 8000

4. error-pages used by Errors class

Dynamic handlers configuration

if you want more handling control:

• specify path field for static file response
• use handler object description as
  • source to choose handler path
  • post name of function to handle POST request
  • get name of function to handle GET request
• specify headers for additional headers to be added

1. static file response localhost:8000/my_guest_book url

   "/my_guest_book": "tmp/my_guest_book.html",
   

   router will match this url and send file tmp/my_guest_book.html

2. custom GET handler for localhost:8000/posts url

   "/posts": {
     "handler": {
       "source": "handlers/my_guest_book.py",
       "get": "get_posts"
     }
   }
   

   this will start loaded source handler search for url and call get_posts function

3. custom POST handler for localhost:8000/post url

    "/post": {
      "handler": {
        "source": "handlers/my_guest_book.py",
        "post": "handle_post"
      }
    }
   

   it will call handle_post function from source found handler and process request in that module

Dynamic handlers usage

Handlers should be added as modules with 1 or 2 functions (which are configured if config.json as it was described in here)

Its signature needs to be

def function(request: Request, server: Server) -> Response:

Here you can use Server and Request that is being processed

Request structure:

• self.method - request method (GET/POST)
• self.target - url
• self.version - HTTP version
• self.headers - headers dictionary
• self.body - request body

Use this properties as you need to process the request

Logging and debug

If you want std.out as primary output use -l console

If you want file as output use -l logging

There is a logger.py for server info logging and debug, configure LOGGER_PATH and LOG_DEBUG_PATH in defenitions.py
