It would be nice to have a request.json() shortcut.

As far as I'm aware, it's a duplicate of #27415.

I think this also relates to #32259. Completing the ​content negotiation story as suggested on #27415 would be the significant benefits justifying changes in #32259. 🤔

There's also #21442 for Tom Christie's work.

I think adding request.json() would be a bit of a mis-feature, when we could instead add request.data with a parsing framework that's more "future-proof". It would be based on DRF's behaviour, so would be familiar to most Django devs already.

I can see the case for content negotiation.

My two sense: In browsers, there's a standard .json() method for http responses [0], and the Python requests library also has .json() method, so a simple .json() method is becoming more of the norm for a lot of simple use cases.

I don't think I'd be wrong if I said most apis only need to speak json. Content negotiation, while needed for some use cases, is probably overkill for many people's. Some people aren't going to want their endpoint to accept xml and yaml.
