Laravel - 用户“sa”的 SQL Server 连接失败

Question

我正在尝试了解有关 Laravel 框架的更多信息，但陷入了数据库连接问题。

我已经仔细检查了主机名、数据库名称、用户名和密码，一切都正确。但是当我尝试在我的作曲家中执行php artisan migrate功能时，它显示这样的错误

SQLSTATE[28000]: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Login failed for user 'sa'.

我不知道为什么会发生这种情况，我也尝试使用纯PHP语法连接数据库，没有问题。有人可以解释一下吗？我很感谢这里提供的任何信息。之前非常感谢..

这是我的.env文件：

DB_CONNECTION=sqlsrv
DB_HOST=NDUT-PC\SQLEXPRESS
DB_DATABASE=SampleDB
DB_USERNAME=sa
DB_PASSWORD=48a365b4ce1e322a55ae9017f3daf0c0

这是我的database.php文件：
