lwp-request in shell: how to make POST request with body?

Question

I use simple shell script to test some http server that process POST requests. Usually it looks like:

echo "param1=value1&param2=value2" | POST localhost/service

But now I want to pass also some json in POST body and that's where I missing point completely.

man POST and google did't help much also.

Seems it must be either very simple or completely impossible.

Thanks for help.

Answer 1

Either I'm missing something, or you should do

$ echo -n '{"json":"data"}' | POST -c "application/json" 'http://localhost/service?param1=value1&param2=value2'

If you need to put those parameters not as GET, but as POST as well, then look up multipart form data.

Answer 2

You probably need to pass content type using -c:

POST -c application/json
