CURL HTTP POST

HTTP GET, generic

# Generic request, just like wget.  (v)erbose, (s)ilent, suppress progress bar meter
curl -vs http://remote.http.site

HTTP GET, with basic auth

feel free to use --anyauth or --negotiate to properly match preferred auth.
Usually --anyauth is preferred for basic realm

curl --anyauth --verbose --user 'username:password' "http://your.http.host.name/YOUR/REST/API"

Extract HTTP Response Code

You can use curl for retrieving the HTTP status code alone or have it combined with the usual stdout. For example"

# stdout AND http status code
curl -w "%{http_code}" "http://remote.http.site/whatever/URI/you/have"
# http status code only, quite handy in scripts
curl -w "%{http_code}" -o /dev/null "http://remote.http.site/whatever/URI/you/have"

HTTP Form POST

curl \
    --header "Authorization: key=AIzaSyAJdz6YkUNwb6lWtsyBV3XfhqldVHGUqtQ" \
    --header Content-Type:"application/json" https://gcm-http.googleapis.com/gcm/send \
    -d "{\"registration_ids\":[\"fARzJ0ysrZIxHpYSSg6wZTfURcuKwEGdCl0bku7n\"],\"data\":{\"title\":\"My Cool Title\"} }"

HTTP Form POST JSON data

curl -d '{"key1":"value1", "key2":"value2"}' -H "Content-Type: application/json" -X POST http://localhost/form

HTTP Upload file

# As a multipart    (multipart/form-data)
curl -F "[email protected];filename=NameOfTheFileInPOST.txt" "http://remote.http.site/upload"

# As a binary file  (application/x-www-form-urlencoded)
curl --request POST --data-binary "@bigfile.img" "http://remote.http.site/upload"

insecure

in your .curlrc file and everything is fine.
