Rest web service post method. -insecure

hello everyone
I'm nobuhiro yane.

curl --insecure or curl -k of Rest web service post method

I want to ignore the SSL certificate

As an option when posting with Rest API
  I would like to add --insecure or -k, but where on the screen should I set it?

If anyone knows, could you please let me know?
please.

It replaces the following
curl -k
curl --insecure
