[JulianGR]

Hello, I'd like to discuss 2 enhancements. I've written them separated, so its easier to track. The other one is #1118

FEATURE REQUEST 1: automatic Content-Type

Is your feature request related to a problem? Please describe.

When using the --data flag, one must also specify the Content-Type header in the config file.

Describe the solution you'd like

When using x-www-form-urlencoded, such as with

-m POST --data 'grant_type=password&username=admin&password=aaa'

it could be nice if the tool automatically detects the encoding, and adds a header like: Content-Type: application/x-www-form-urlencoded

As another example, when using json such as with

-m POST --data '{
  "grant_type": "password",
  "username": "admin",
  "password": "aaaa"
}'

it could be nice if the tool automatically detects the encoding, and adds a header like: Content-Type: application/json

Describe alternatives you've considered

I know this feature could be hard to implement, but I believe It can be simple. Basically with

• Content-Type: application/x-www-form-urlencoded
• Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryXXX
• Content-Type: application/json

you have 99% of body encodings covered.

howdy, and thanks for submitting these requests!

i took a brief look to see if guessing content-type was provided by one the libraries already in use within ferox. Unfortunately, that functionality isn't present. I didn't immediately see any other premade options either. Pinning this for now, as it's a nice quality of life improvement, but it's a heavier lift than i'm able to do at the moment.
