Parses a JSON request body of the intercepted request

[kettanaito]

Changes

• Parses a JSON request body of the intercepted request, so now req.body is contextually an Object or a string, with no need to explicitly parse it.

GitHub

• Fixes "application/json" req.body is not parsed #159

Roadmap

• Parse a response JSON body when viewing the logs

Encountering this exception during response-patching test:

TypeError: Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body.
(see more detailed error stack trace in the mocked response body)

Reason

Caused by a non set req.body received from the worker being treated as an empty string.

Solution

Handles request body outside of the JSON parsing of the worker's message.
