Getting Started

to create a katari project run the following command in your terminal

katari --build-app <project name>

app.py

import settings
from Katari import KatariApplication
from Katari.sip.response import ResponseFactory

app = KatariApplication(settings=settings)

@app.invite()
def do_invite(request, client):
    # add INVITE logic here 
    response = ResponseFactory.build(200) # 200 OK
    app.send(request.create_response(response), client)

@app.register()
def do_register(request, client):
    # add REGISTER logic here 
    response = ResponseFactory.build(401) # 401 unauthorized 
    app.send(request.create_response(OK200()), client)

@app.options()
def do_options(request, client):
    # add OPTIONS logic here 
    response = ResponseFactory.build(200) # 200 OK
    app.send(request.create_response(response), client)

@app.info()
def do_info(request, client):
    # add INFO logic here 
    response = ResponseFactory.build(200) # 200 OK
    app.send(request.create_response(response), client)

if __name__ == "__main__":   
    app.run()

Writing your own middleware

create a directory called middleware within your project

myproject -
   - app.py
   - settings.py
   - middleware   << LIKE THIS 
     - __init__.py
     - test.py

your middleware can modify the sip message before it reaches your main logic using the process_request method and also modify the response before it gets sent back to the client using process response method.

Example

test.py

from Katari.interfaces import MiddlewareInterface

class Test(MiddlewareInterface):

    def process_request(self, message):
        print(str(message))
        return message


    def process_response(self, message):
        print(str(message))
        return message

settings.py
