Laravel 5.2: Captcha fails check even when it's correct about captcha

[tennessine]

I changed vendor/mews/captcha/src/CaptchaServiceProvider.php file to

<?php

namespace Mews\Captcha;

use Illuminate\Support\ServiceProvider;

/**
 * Class CaptchaServiceProvider
 * @package Mews\Captcha
 */
class CaptchaServiceProvider extends ServiceProvider {

    /**
     * Boot the service provider.
     *
     * @return null
     */
    public function boot() {

        // Publish configuration files
        $this->publishes([
            __DIR__ . '/../config/captcha.php' => config_path('captcha.php'),
        ], 'config');

        // HTTP routing
        if (strpos($this->app->version(), 'Lumen') !== false) {
            $this->app->get('captcha[/{config}]', 'Mews\Captcha\LumenCaptchaController@getCaptcha');
        } else {
            $this->app['router']->get('captcha/{config?}', ['middleware' => 'web', 'uses' => '\Mews\Captcha\CaptchaController@getCaptcha']); // modify here
        }

        // Validator extensions
        $this->app['validator']->extend('captcha', function ($attribute, $value, $parameters) {
            return captcha_check($value);
        });
    }

    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register() {
        // Merge configs
        $this->mergeConfigFrom(
            __DIR__ . '/../config/captcha.php', 'captcha'
        );

        // Bind captcha
        $this->app->bind('captcha', function ($app) {
            return new Captcha(
                $app['Illuminate\Filesystem\Filesystem'],
                $app['Illuminate\Config\Repository'],
                $app['Intervention\Image\ImageManager'],
                $app['Illuminate\Session\Store'],
                $app['Illuminate\Hashing\BcryptHasher'],
                $app['Illuminate\Support\Str']
            );
        });
    }

}

It works. I don't know why

@w3hacker your code modification has fixed the problem. Thank you very much!

Closing this now, hopefully the author will merge the edit into the code base to make it Laravel 5.2 ready.
