Usage

-----

.. code:: python

    import asyncio

    from aiohttp import web

    from aiohttp_exc_handlers import (

        exc_handlers_middleware,

        bind_exc_handler,

    )

    class CustomException(Exception):

        pass

    async def custom_exception_handler(request, exc):

        return web.Response(text="Hello, {!s}!".format(exc))

    async def hello(request):

        raise CustomException('world')

    # add middleware

    app = web.Application(middlewares=[exc_handlers_middleware])

    # bind handler to exception

    bind_exc_handler(app, CustomException, custom_exception_handler)

    app.router.add_route('GET', '/', hello)

    loop = asyncio.get_event_loop()

    handler = app.make_handler()

    f = loop.create_server(handler, '0.0.0.0', 8080)

    srv = loop.run_until_complete(f)

    try:

        loop.run_forever()

    except KeyboardInterrupt:

        pass

    finally:

        loop.run_until_complete(handler.finish_connections(1.0))

        srv.close()

        loop.run_until_complete(srv.wait_closed())

        loop.run_until_complete(app.finish())

    loop.close()
