laravel找不到支持的加密器.密码和/或密钥长度无效

Question

我正在使用Laravel构建一个项目.它在localhost上工作正常,但是当我将它上传到服务器(服务器安装了comodo ssl)时,我收到以下错误:

RuntimeException in EncryptionServiceProvider.php line 29:
No supported encrypter found. The cipher and / or key length are invalid

任何人都可以帮助解决此错误？

Answer 1

您只需键入控制台:

php artisan key:generate

如果您的app.php没有更改此密钥,请手动更改.

接下来,如果您应该碰巧收到此错误消息:

[ErrorException]
file_get_contents(/path/to/my/project/.env):无法打开流:没有这样的文件或目录

然后复制该.env.example文件,然后重试:

cp .env.example .env
php artisan key:generate

Answer 2

您是否在服务器上安装了所有必要的扩展程序？

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

可能是你错过了OpenSSL扩展.此外,你有.env文件中的密钥集吗？

试试跑步:

php artisan key:generate

答:'cipher' => ''没有设定.

Answer 3

我之前有同样的问题,我按照这种方式修复它:转到config/app.php,"cipher" => "anything"改为

'cipher' => MCRYPT_RIJNDAEL_128,

Answer 4

我通过运行这个来修复它:

php artisan config:cache

Answer 5

我只是修正错误.

1. Shift+Click 右键从你的根项目"在这里打开推荐窗口".
2. 在控制台写:"php artisan key:generate".
3. 得到32个字符'Mark'来config/app.php赞'key' => env('APP_KEY', 'insert get 32 char key'),//第81行

Answer 6

就我而言，我需要启用 mcrypt 扩展。

但首先，检查您是否已经拥有它：

$ sudo apt-get install -y mcrypt php5-mcrypt

检查 mcrypt 模块是否已加载：

$ php -m | grep mcrypt

如果什么都不显示，是因为没有加载，但是你上面已经安装了对吗？所以这样做：

$ php5enmod mcrypt
$ sudo service apache2 restart

再次检查，您应该看到 mcrypt 而不是什么都没有。这是一个好兆头，重新加载您的应用程序并修复您的下一个错误；）

$ php -m | grep mcrypt
mcrypt

Answer 7

在根目录中,如果有.env.example文件,则将其更改为.env然后运行php artisan key:generate.这对我有用.
