Question

我正在Laravel 5.4中配置我的postgresql驱动程序以部署到Heroku。这是我的config / database.php，default已设置为pgsql

'pgsql' => [
        'driver' => 'pgsql',
        'host' => parse_url(getenv("DATABASE_URL"))['host'],
        'database' => substr(parse_url(getenv("DATABASE_URL"))['path'], 1),
        'username' => parse_url(getenv("DATABASE_URL")['username']),
        'password' => parse_url(getenv("DATABASE_URL")['password']),
        'charset' => 'utf8',
        'prefix' => '',
        'schema' => 'public',
    ],

当我提交时，我会看到此警告

PHP Warning: Illegal string offset 'username' in app/config/database.php on line 62

运行时heroku run php artisan serve我收到错误

[Symfony\Component\Debug\Exception\FatalThrowableError]  
Type error: PDO::__construct() expects parameter 2 to be string, array given

这是我的.env

DB_CONNECTION=pgsql
DB_HOST=127.0.0.1
DB_PORT=5432
DB_DATABASE=forge
DB_USERNAME=postgres
DB_PASSWORD=

如果要从提供的.env中获取正确的数据，您的配置数组应如下所示。

'pgsql' => [
            'driver' => 'pgsql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '5432'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8',
            'prefix' => '',
            'schema' => 'public',
            'sslmode' => 'prefer',
        ]
