Bash function to curl an HTTP JSON API, print the headers, and then print the body formatted using jq

jcurl.sh

# Bash function to curl an HTTP JSON API, print the headers,
# and then print the body formatted using jq
#
# Example usage: jcurl https://api.github.com/users/cirla

function jcurl() {
  # disable progress bar and print headers to stdout
  response=$(curl -sD - $@)
  
  # split response at the first empty line (ignoring whitespace)
  # sed on OS X neither recognizes \r as a special character nor matches
  # carriage returns with \s, so we have to insert a carriage return using printf
  echo "$response" | sed "/^\s*$(printf '\r')*$/q"
  echo "$response" | sed "1,/^\s*$(printf '\r')*$/d" | jq .
}

Or just brew install httpie and save yourself the time dealing with corner cases.

Or use curl -v, which sends the verbose output to stdin and actual data to stdout
