Installation

------------

.. code-block:: shell

    pip install aiohttp_request

Usage

-----

.. code-block:: python

    import asyncio

    from aiohttp import web

    from aiohttp_request import ThreadContext, middleware_factory, grequest, get_request

    def thread():

        assert grequest['sense'] == 42

    async def task():

        # grequest is `lazy` version of request

        assert grequest['sense'] == 42

        loop = asyncio.get_event_loop()

        # works for threads as well with ThreadContext

        await loop.run_in_executor(None, ThreadContext(thread))

    async def hello(request):

        # get_request is on-demand function to get current request

        assert get_request() is request

        request['sense'] = 42

        # asyncio.Task is supported

        await asyncio.ensure_future(task())

        return web.Response(text="Hello, world")

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

    app.add_routes([web.get('/', hello)])

    web.run_app(app)

Python 3.7+ is required, there is no way to support older python versions!!!

Notes

-----

The library relies on `PEP 567 `_ and its `asyncio support `_

aiohttp-request works nicely with threads via `contextvars_executor `_ , no `ThreadContext` is needed

.. code-block:: python

    import asyncio

    from aiohttp import web

    from aiohttp_request import middleware_factory, grequest

    from contextvars_executor import ContextVarExecutor

    def thread():

        assert grequest['sense'] == 42

    async def hello(request):

        request['sense'] = 42

        loop = asyncio.get_event_loop()

        await loop.run_in_executor(None, thread)

        return web.Response(text="Hello, world")

    loop = asyncio.get_event_loop()

    loop.set_default_executor(ContextVarExecutor())

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

    app.add_routes([web.get('/', hello)])

    web.run_app(app)
