How to heandle 404 error ?

[vadim-shadrin]

I temporary replace string 76 in /japronto/app/init.py

• return request.Response(code=404, text='Not Found')
• return request.Response(code=302,headers={'Location':'notfound'}) and addroute: /notfound and it's work but . I whould not want to change global package

That's the right solution You need to override the method

from japronto.router import RouteNotFoundException import asyncio import traceback import sys

class App(Application): def default_error_handler(self, request, exception): if isinstance(exception, RouteNotFoundException):

return request.Response(code=404, text='Not Found'

         return request.Response(code=302,headers={'Location':'notfound'})
    if isinstance(exception, asyncio.CancelledError):
        return request.Response(code=503, text='Service unavailable')
    tb = traceback.format_exception(
        None, exception, exception.__traceback__)
    tb = ''.join(tb)
    print(tb, file=sys.stderr, end='')
    return request.Response(
        code=500,
        text=tb if self._debug else 'Internal Server Error')
