Simple Python Web API framework, based on Gevent, JSON, CRUD.

Project description


  • Based on gevent.wsgi, optimized for tens of thousands of concurrent users.

  • Simple! Try it:

    mkdir -p myproduct/api/v0
    touch {myproduct,myproduct/api,myproduct/api/v0}/
    cat <<END >myproduct/api/v0/
    # from myproduct.api import anything
    def read(request):
        response = request.copy()
        response.server = 'myproduct'
        return response
    sudo apt-get install --yes gcc libevent-dev python-dev
    sudo pip install apiphant
    apiphant myproduct
    # POST http://{host}:{port}/api/{version}/{t/a/r/g/e/t}/{action}
    curl --data-binary '{"hello": "world"}' --request POST
    {"hello": "world", "server": "myproduct"}
  • Automated functional tests in Python:

    apiphant myproduct
    cat <<END >
    from apiphant.test import test
    test('echo', 'read', {"hello": "world"}, 200, {"hello": "world", "server": "myproduct"})
    POST {"hello": "world"} --> 200 {'hello': 'world', 'server': 'myproduct'}
  • Please see how this shell script can help to run Python tests in

  • Optional full-stack deploy! Supervisor, Nginx, Logrotate, Apt, Pip, etc.

    • Copy myproduct template.

    • Replace myproduct with your product name in all configs and scripts.

    • Run root and enjoy the show.

    • This deploy framework is going:
      • To get Virtualenv bootstraper.

      • To be extracted to a separate opensource repo.

  • Validate request fields and subfields, raise errors:

    from apiphant.validation import ApiError, field, Invalid
    def read(request):
        id = field(request, 'id', is_required=True, valid_type=int)
        # More options: default_value, valid_value, valid_length, max_length, explain.
        item = get_item(id)
        if not item:
            raise Invalid('id')
            # that is a shortcut for:
            raise ApiError(400, 'id is Invalid')
        raise Invalid('id', id) # 'id is Invalid: -1'
  • version value v0 used in the example means API is not public yet, and maybe never will, so is expected to be changed without notification.

  • action is one of CRUD: create, read, update, delete.

  • Reasons why CRUD is implemented without use of HTTP methods that are recommended by REST:

    • Best match for generally partial «Update» action is PATCH method, but it is not supported by our gevent.wsgi webserver and several clients.

    • Much more standard PUT method means «Replace», that is not how «Update» should work in general case. Imagine SQL UPDATE working as «Replace».

    • Some cases allow only GET and POST, e.g. cross-origin requests in some browsers, while at least DELETE method is required for full set of actions.

    • So POST is selected as «a uniform method», suitable for all actions: «The actual function performed by the POST method is determined by the server» - HTTP/1.1.

  • {“json”: “object”} is used for both request and response, to speak one language easily with any client.

  • However, URL still contains several request parameters, because:

    • Different targets may be routed by load balancers to different backend servers using simple URL location routing.

    • version, target and action are always required, so may be positional parameters, improving readability and saving resources in a natural way.
