[Flask] Flask Digest, Vol 7, Issue 11

[Chukwudi Nwachukwu]

Found this somewhere online long time ago:
In the most common cases, request.data is going to be empty, because, as
stated in the docs, it's used as a fallback:

    request.data Contains the incoming request data as string in case it
came with a mimetype Flask does not handle.

    request.args : If you want the parameters in the URL
    request.form : If you want the information in the body (as sent by a
html POST form)
    request.values : If you want both
