在 App\Console\Commands下 添加以下内容的KeyGenerateCommand.php文件
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
class KeyGenerateCommand extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'key:generate';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Set the application key';
/**
* Execute the console command.
*
* @return void
*/
public function handle()
{
$key = $this->generateRandomKey();
file_put_contents(base_path('.env'), preg_replace(
'/^APP_KEY=[\w]*/m',
'APP_KEY='.$key,
file_get_contents(base_path('.env'))
));
$this->info("Application key [$key] set successfully.");
}
/**
* Generate a random key for the application.
*
* @return string
*/
protected function generateRandomKey()
{
return str_random(32);
}
}
将指令注入
修改App\Console 下的Kernel.php 文件
protected $commands = [
//注入指令
'App\Console\Commands\KeyGenerateCommand',
];
现在可以使用 php artisan key:generate 指令 修改 .env中的APP_KEY 的值
