How to avoid using php://input?

Question

I have a POST endpoint that receives a JSON payload.

I'm using the Magento\Framework\App\Request\Http class to try and retrieve my POST data.

If I run $data = $this->request->getPost();, then $data will be empty.

However if I run $data = file_get_contents('php://input'); I am able to view my JSON payload as a string.

Is there a way to grab this natively through Magento?

FWIW I'm testing this through a rest/V1 endpoint through Postman.
This is a POST request with a chunk of (valid) JSON data in the raw data type.

Assuming $this->request is an instance of Magento\Framework\App\Request\Http, you can use the code below to get the JSON post body.

$json = $this->request->getContent();
$data = json_decode($json);
