.
‘key' => env(‘APP_KEY', ‘base64:insert key here'),
.

check the "key" variable form your config/app.php file, it should be
检查 config/app.php 文件中的“key”变量，它应该是

And Restart your php server.

Add empty APP_KEY=inside .env without value if not exist, then delete config.phpinside bootstrap/cacherun php artisan key:generate
APP_KEY=如果不存在则config.php在没有值的 .env 中添加空，然后在bootstrap/cache运行中删除php artisan key:generate

Yes the php artisan key:generatewill generate the key for you. like this in console
是的，php artisan key:generate它将为您生成密钥。像这样在控制台
$php artisan key:generate
Application key [base64:soAqqNW/Kk85OclhmCKXj+u4nZGF142gEZHEY0Y1NXA=] set successfully.
$php artisan key:generate
Application key [base64:soAqqNW/Kk85OclhmCKXj+u4nZGF142gEZHEY0Y1NXA=] set successfully.
you need to copy this key and put it into your .env file in APP_KEY=parameter.
您需要复制此密钥并将其放入您的 .env 文件中的APP_KEY=参数中。
