我正在使用 Laravel Framework 10.15.0。

我尝试以以下方式加载我的API密钥：

$apiKeyOpenAI = env('OPENAI_API_KEY');
        $client = OpenAI::client($apiKeyOpenAI);

在我的 .env 文件中，API密钥已经明确定义：

OPENAI_API_KEY=xx-xxxxxxxxxxxxxxxxxxxxxxx

然而，在服务器上执行我的应用程序时，我得到的 $apiKeyOpenAI 是null。

但是，我的 .env 文件中确实有 OPENAI_API_KEY。我已经检查过了！

我尝试清除缓存 php artisan config:clear ，但仍然出现错误：

TypeError 

  OpenAI::client(): Argument #1 ($apiKey) must be of type string, null given, called in /var/www/demo-website/app/Console/Commands/AdminCommand.php on line 151

      OpenAI::client()

  2   app/Console/Commands/AdminCommand.php:39

有什么建议我做错了吗？

感谢您的回复！

更新

在部署到服务器后，我需要运行此脚本以使其正常工作：

Route::get('/clear', function() {
    Artisan::call('cache:clear');
    Artisan::call('config:clear');

    return "Cache, Config is cleared";
})->middleware(['auth', 'admin']);

在部署时，此脚本也会自动运行：

#!/bin/sh
set -e

echo "Deploying application ..."

# Enter maintenance mode
(php artisan down) || true
    # Update codebase
    git fetch origin deploy
    git reset --hard origin/deploy

    # Install dependencies based on lock file
    composer install --no-interaction --prefer-dist --optimize-autoloader

    # Migrate database
    php artisan migrate --force

    # Note: If you're using queue workers, this is the place to restart them.
    # ...


    # Clear cache
    # php artisan optimize

    php artisan config:cache
    php artisan route:clear
    php artisan route:cache
    php artisan view:clear
    php artisan view:cache
    php artisan auth:clear-resets
    php artisan cache:clear
    php artisan config:clear

    # Generate sitemap
    # php artisan sitemap:generate

    # Reload PHP to update opcache
    echo "" | sudo -S service php8.1-fpm reload
# Exit maintenance mode
php artisan up

echo "Application deployed!"
