laravel中的多个数据库连接

Question

我正在尝试与laravel建立多个数据库连接。

这是我的env文件：

DB_CONNECTION=mysql
DB_HOST=ip
DB_PORT=3306
DB_DATABASE=laravel
DB_USERNAME=root
DB_PASSWORD=pass

DB_EXT_HOST=ip
DB_EXT_DATABASE=laravel
DB_EXT_USERNAME=su
DB_EXT_PASSWORD=pass
DB_EXT_PORT=1433

我的database.php文件

'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'strict' => false,
            'engine' => null,
        ],
'sqlsrv' => [
            'driver' => 'sqlsrv',
            'host'     => env('DB_EXT_HOST', 'localhost'),
            'port' => env('DB_EXT_PORT', '1433'),
            'database' => env('DB_EXT_DATABASE', 'database'),
            'username' => env('DB_EXT_USERNAME', 'root'),
            'password' => env('DB_EXT_PASSWORD', ''),
            'prefix' => '',
        ],

我正在尝试将sqlsrv与此代码连接起来。但它给了我错误。

$db_ext = DB::connection('sqlsrv');
