回答1:

Just add the csrf token as follows in the form :

<input type="hidden" name="_token" value="{{csrf_token()}}"/>

it worked for me.

回答2:

Assume that your web server has already write access to session directory, in my case 'app/storage/framework/sessions/'.

Execute:

$ rm -f {your_web_app}/storage/framework/sessions/*

回答3:

There are several possibilities...

1) If you have any spaces at all in front of your opening <?php tag, it can cause this error (especially if you're using AJAX). So just double-check to make sure that there's nothing before <?php in your files.

2) If you're trying to submit this form data via AJAX, the docs suggest passing the CSRF token like so:

Add this meta tag to your <head>:

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

And then do this in the AJAX call:

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

回答4:

If your using laravel 5.1 simply adding {{ csrf_field() }} would do the trick

回答5:

The csrf token will be added automatically if you use the open and close tags for Form

{!! Form::open(['action' => '/auth/register', 'class' => 'ui large form']) !!}

-- Form stuff here --

{!! Form::close() !!}

回答6:

i hope this will help

set meta-tag like follows

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

then request like follows

$.ajax({
    data: {data1:'data1',data2:'data2'},
    url: '/your/url/goes/here',
    type: 'POST',
    beforeSend: function (request) {
        return request.setRequestHeader('X-CSRF-Token', $("meta[name='csrf-token']").attr('content'));
    },
    success: function(response){
        console.log(response);
    }
})
