[kwlug-disc] Utility to parse HTTP response

[Anton Avramov]

Hi William, 

You can have curl do it for you: 

Option 1: Used --output and --dump-headers switches to write the
headers and the body of the request in separate files. Then it is
trivial to get the response code with head -n 1 <header dump file>. 

Option 2: You can use --write-out switch to actually format the output
(including headers, http_code etc) in whatever best works for you.

P.S. looking for the --write-out switch in the manual I see it has: 
json           A JSON object with all available keys. (Added in 7.70.0)
So it would be possible to use that and then jq again.

Cheers
