Laravel 5.1令牌在登录表单POST上不匹配

Question

I'm getting the following error TokenMismatchException in compiled.php line 2930:

The code is running on a Red Hat server with php 5.6 i have also tested this on a Ubuntu server running php 5.5.9 it worked perfectly fine. It also runs perfectly locally.

It seems to create 2 session files in storage/framework/sessions on the original GET request which means when the form is sent via POST the session is then different.

I have checked for

• Redirects
• Date/Timezone issue across the server
• Config issues within session.php and app.php

The strangest thing is why there is 2 session files being generated on the GET request.

As soon as you hit the login button you hit the csrf middleware saying the tokens don't match.

I am using the HTML generator for forms which means the _token is being set so it doesn't need to happen manually.

Form code

{!! Form::open(['action' => 'Auth\AuthController@login']) !!}

<div class="panel">

    <div class="panel-title">
        Login
    </div>

    <div class="panel-body">

        <div class="grid">

            <div class="grid-2-4 grid-prepend-1-4 grid-append-1-4">

                @include('shared._errors')

                <div class="field">
                    {!! Form::label('username', 'Employee username') !!}
                    {!! Form::text('username') !!}
                </div>

                <div class="field">
                    {!! Form::label('password', 'Password') !!}
                    {!! Form::password('password') !!}
                </div>

                <div class="actions">
                    {!! Form::submit('Login', ['class' => 'button large']) !!}
                </div>

            </div>

        </div>

    </div>

</div>

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

If there is anything else that would be helpful let me know.

Answer 1

Finally got to the bottom of the issue.

It was to do with this line in the session.php config file.

'domain' => '.'.config('app.domain')

This line is getting the domain from the config.php file which in turn gets it from the .env file.

Ubuntu and Locally in Homestead which is also Ubuntu this works flawlessly.

However on Red Hat this does not work at all. Altering the line to be 'domain' => '.'.env('APP_DOMAIN') and voilà all is right with the world and the TokenMissmatch has gone.
