Laravel 5.1 - Posting and Retrieving JSON

This is how you can use jQuery to POST data and retrieve it within the controllers.


To Send Data:

First off on the page where you are POSTing data from, you need to have a CSRF_TOKEN as a meta tag.

<meta name="csrf_token" content="{{ csrf_token() }}" />

Then in the JavaScript, pull the token and send it along with the POST as headers.

<script type="text/javascript">

var CSRF_TOKEN = $('meta[name="csrf_token"]').attr('content');
  
var jsonData = "{ 'data' : 'data' }";  

$.ajax({
    url: '/route/path',    
    type: 'POST',
    data: jsonData,
    headers: {
     'X-CSRF-TOKEN': CSRF_TOKEN
    },   
    dataType: 'JSON',
    success: function (data) { }
});

</script>

To Retrieve Data:

Setup a post route in /app/Http/routes.php

Route::post('/route/path', 'ControllerName@controllerMethod');

Then setup the controller

class ControllerName extends Controller
{
    public function controllerMethod()
    {
        $jsonData = Input::json()->all();

         // Do Something Here

        return response()->json("{ 'data' : 'data' }");
    }
}
