从Laravel 5.1到5.2后，EncryptionServiceProvider.php问题

Question

我已经完成了$php artisan key:generate和$php artisan config:cache。钥匙确实会在我的电脑中生成。在执行artisan生成命令时使用env文件，这很好。

我注意到这是在我从Laravel5.1升级到Laravel5.2并在我的EncryptionServiceProvider上将“bindshared”更改为“singleton”之后开始的。当从5.1更新到5.2时，我被提示使用php。

我已经在这个问题上被难倒了好几个星期了，似乎在网上找不到任何有用的东西。提前谢谢！

以下是我得到的错误：

RuntimeException in EncryptionServiceProvider.php line 45:
No supported encrypter found. The cipher and / or key length are invalid.

这是EncryptionServiceProvider。php文件：

<?php

namespace Illuminate\Encryption;

use Illuminate\Support\Str;
use Illuminate\Support\ServiceProvider;

class EncryptionServiceProvider extends ServiceProvider
{
    /**
     * Register the service provider.

     */

    {
        $this->app->singleton('encrypter', function ($app) {
            $config = $app->make('config')->get('app');

            if (Str::startsWith($key = $config['key'], 'base64:')) {
                $key = base64_decode(substr($key, 7));
            }

            return $this->getEncrypterForKeyAndCipher($key, $config['cipher']);
        });
    }

    /**

     */
    protected function getEncrypterForKeyAndCipher($key, $cipher)
    {
        if (Encrypter::supported($key, $cipher)) {
            return new Encrypter($key, $cipher);
        } elseif (McryptEncrypter::supported($key, $cipher)) {
            return new McryptEncrypter($key, $cipher);
        } else {
            throw new RuntimeException('No supported encrypter found. The cipher and / or key length are invalid.');
        }
    }
}
