Lumen Ajax发布

I am developing a web application using the Framework Lumen. I looked everywhere, I tried everything but I couldn't find a solution to my problem..

I have a form that I want to validate with jQuery using ajax() with POST. I tried to use csrf_token, but always without success.

VIEW :

<form id="form">
    <div class="form-group">
        <input type="text"  class="form-control" name="test" placeholder="Test">
    </div>
    <button type="button" class="btn btn-primary btn-block valide">Submit</button>
</form>

JS :

$('.valide').click(function () {
    var form = $(this).parents('form');
    $.ajax({
        type: 'POST',
        url: '/testAjax',
        dataType: 'JSON',
        data : form.serialize()
    }).done(function (data) {
        // done
    }).fail(function () {
        // fail
    });
});

routes.php :

$app->post('/testAjax', function () {
    return 'I am here';
});

Normally I would get the message "I am here", but instead, I get the following error (Please note that if I make the same request using GET, it works very well):

POST http://localhost/testAjax 500 (Internal Server Error)

How to make an ajax POST request using Lumen?

change the route

 $app->post('/testAjax', function () {
    return 'I am here';
 });

to

 $app->post('testAjax', function () {
    return 'I am here';
 });

I found the solution. Simply add the following code to the HTML form, allowing the user to be associated to the current form. This is described in the documentation.

VIEW :

<form id="form">
    <!-- Added the following line -->
    <input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
    <div class="form-group">
        <input type="text"  class="form-control" name="test" placeholder="Test">
    </div>
    <button type="button" class="btn btn-primary btn-block valide">Submit</button>
</form>

Also if someone would not send jQuery POST via form you can simply add to your script code below:

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

Remember to include this html inside your view:

<meta name="csrf-token" content="{{ csrf_token() }}">
