[Bug]: GET requests accept a request body

[severussundar]

What happened?

When a GET request is executed by including a request body, the request succeeds.

Request URI: https://localhost:5001/api/Book/id/1
Request Body:

{
    "title": "Awesome book",
    "publisher_id": 1234
}

Response:

{
    "value": [
        {
            "id": 1,
            "title": "Awesome book",
            "publisher_id": 1234
        }
    ]
}

The data entered in the request body is ignored. While, the right response is returned, it might be worth returning a bad request (HTTP 400) response as the request body is irrelevant for GET requests.

Similar behavior happens for list operation as well

As per the RFC and stackoverflow discussions, GET requests can contain a request body but the server processing the request should not parse and alter the behavior/response of the API based on the contents of the request body.

At the moment, DAB already adheres to this. Although the request body needs to be ignored, returning a bad response for such requests is not completely in-line with the RFC. Therefore, closing this issue
