Add Response.ajson

[ToxicKidz]

Since there's already Resonse.json() and Response.aread(), why not have Response.ajson?

Current Solution

data = json.loads(await response.aread())

# OR

await response.aread()
data = response.json()

Implementation

The implementation would be fairly easy:

class Response:
    ...
    async def ajson(self, **kwargs: Any) -> Any:
        await self.aread()
        return self.json(**kwargs)

So, this wouldn’t make sense as a counterpart because .json() doesn’t read the response body.

Let’s explain that more clearly. There’s no need for an ajson(), because this already works just fine...

r = await client.get(...)
r.json()  # There’s no I/O occurring here.

The only case where you need to explicitly perform I/O is in the streaming case.

async with client.stream(...) as r:
    await r.aread()
    r.json()  # Can only call .json once we’ve loaded the response body.

Which anyway matches the style you’d need to use in the sync case...

with client.stream(...) as r:
    r.read()
    r.json()  # Can only call .json once we’ve loaded the response body.
