laravel 找不到支持的加密器.密码和/或密钥长度无效 [英] laravel No supported encrypter found. The cipher and / or key length are invalid

问题描述

我正在使用 Laravel 构建一个项目.它在本地主机上运行良好，但是当我将它上传到服务器时(服务器安装了 comodo ssl)，我收到以下错误:

I am building a project using Laravel. It was working fine on localhost, but when I upload it to the server (the server has comodo ssl installed), I receive the following error:

RuntimeException in EncryptionServiceProvider.php line 29:

推荐答案

您是否在服务器上安装了所有必要的扩展?

Do you have all the necessary extensions installed on the server?

• PHP >= 5.5.9
• OpenSSL PHP 扩展
• PDO PHP 扩展
• Mbstring PHP 扩展
• Tokenizer PHP 扩展

可能是您缺少 OpenSSL 扩展.另外，您是否在 .env 文件中设置了密钥?

It could be that you're missing the OpenSSL extension. Also, do you have the key set in .env file?

尝试运行:

php artisan key:generate

答案:'cipher' =>'' 未设置.
