Extracting the json post parameter from aiohttp POST Request

Question

currently I do something like this

app.router.add_route('POST', '/foo/{par}', foo_test)

How can I extract the body of the POST from request

@asyncio.coroutine
def foo_test(request):
    body = request.content.read() #returns a generator

My question is how to extract the body from the generator returned ?

Answer 1

body = yield from request.json()
