在Laravel 5.2中使用jquery和ajax的500内部服务器错误

Question

I am building edit post system using jquery and ajax in laravel 5.2. When i click on save changes button in my bootstrap modal, the following error is displayed:

Error: POST http://localhost:8000/edit 500 (Internal Server Error)

send @ jquery-1.12.0.min.js:4

ajax @ jquery-1.12.0.min.js:4 (anonymous function) @ myplace.js:24

dispatch @ jquery-1.12.0.min.js:3

r.handle @ jquery-1.12.0.min.js:3

js code:

$('#modal-save').on('click' , function() {

 $.ajax({

 method : 'POST' ,
 url : url ,
 data: { body: $('#post-body').val(), postid: '' , _token: token }})

.done(function(msg) {

console.log(msg['message']);

    });
  });

Included in view file:

    <script>
    var token='{{ Session::token() }}';
    var url='{{  route('edit') }}' ;
  </script>

It seems like you have problems with our csrf token. Before making your ajax calls just change your ajax setup and put the token in every header you sent via ajax. This should fix your error.

First add a meta tag

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

Then adjust ajax setup

$(function () {
    $.ajaxSetup({
        headers: { 'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content') }
    });
});

or even simpler

$.ajaxSetup({ headers: { 'csrftoken' : '{{ csrf_token() }}' } });
