title: How to post data from react front to laravel background
body: <p>I have a react component, and in it's state, i got some data that need to save in db by php Laravel, how can i do this?
  Should I do this in <code>reducer</code>?
  1. use <code>Ajax</code> 
  2. use form 
  I don't sure if there is a way to use form post data, if it's ok
  Please give me a demo. I'm new to react, and searched no result, thanks!</p>
