This works on ruby 2 4 HTTPS Post with JSON object and the response body written out   require  net http   net https does not have to be required anymore require  json  require  uri   uri   URI  https   your secure-url com   Net  HTTP start uri host  uri port   use ssl   gt  uri scheme     https   do  http    request   Net  HTTP  Post new uri   Content-Type    gt   application json     request body    parameter   value   to json   response   http request request   Net  HTTPResponse object   puts  response   response body   end

HTTParty makes this a bit easier I think  and works with nested json etc  which didn t seem to work in other examples I ve seen   require  httparty  HTTParty post  http   localhost 3000 api v1 users   body   user   email   user1 example com   password   secret     body

It s 2020 - nobody should be using Net  HTTP any more and all answers seem to be saying so  use a more high level gem such as Faraday - Github    That said  what I like to do is a wrapper around the HTTP api call something that s called like  rv   Transporter  FaradayHttp url  options   because this allows me to fake HTTP calls without additional dependencies  ie     if InfoSig env   test   amp  amp    url to s     localhost       response body   FakerForTests url  url  options  options     else     conn   Faraday  Connection new url  connection options   Where the faker looks something like this  I know there are HTTP mocking stubbing frameworks  but at least when I researched last time they didn t allow me to validate requests efficiently and they were just for HTTP  not for example for raw TCP exchanges  this system allows me to have a unified framework for all API communication     Assuming you just want to quick amp dirty convert a hash to json  send the json to a remote host to test an API and parse response to ruby this is probably fastest way without involving additional gems   JSON load  curl -H  Content-Type application json  -H  Accept application json  -X POST localhost 3000 simple api -d    message to json      Hopefully this goes without saying  but don t use this in production
