In-app route definition for authentication callback

[FabienArcellier]

Modifying the fastapi router is complex to carry out from a streamsync application because it is isolated in a subprocess. The streamsync application sees a copy of the fastapi object. Changes are not taken into account.

---

import streamsync as ss

@ss.serve.get('/auth/callback')
def route(state, context):
  state['username'] = 'fabien'

Using redirection

import streamsync as ss

@ss.serve.get('/auth/callback')
def route(state, context):
  state['username'] = 'fabien'
  state.open_url('http://www.google.fr')

Using context

import streamsync as ss

@ss.serve.get('/auth/callback')
def route(state, context):
  request = context.request
  state['username'] = 'fabien'
  state.open_url('http://www.google.fr')
