如何與遠程數據庫sql服務器建立連接？

Question

當嘗試使用enable-migrations連接到遠程數據庫時，我收到一個錯誤，堅持檢查連接字符串，我想要做的就是將我的上下文連接到遠程數據庫，並給 map 一個“用戶”class 和“遷移"，這里是連接字符串：

<add name="TransformerANDConnectDB" connectionString="data source=REMOTE_SERVER_xx ;initial catalog=TransformerANDConnectDB;user id=xxx ;password=xxx ;Integrated Security=True ;MultipleActiveResultSets=True;"  providerName="System.Data.SqlClient" />

否則我向您展示啟用遷移后發生的錯誤：

 ---> System.Data.SqlClient.SqlException: Échec de l'ouverture de session de l'utilisateur 'ADSLOCAL\G558253'. à System.Data.SqlClient.SqlInternalConnectionTds..ctor(DbConnectionPoolIdentity identity, SqlConnectionString connectionOptions, SqlCredential credential, Object providerInfo, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance, SqlConnectionString

訪問數據庫時發生錯誤。 這通常意味着與數據庫的連接失敗。 檢查連接字符串是否正確，是否使用適當的 DbContext 構造函數來指定它或在應用程序的配置文件中找到它。 有關 DbContext 和連接的信息，請參閱http://go.microsoft.com/fwlink/?LinkId=386386 。 有關失敗的詳細信息，請參閱內部異常。

這是我的上下文文件：

public class TransformerConnectMEContext  :DbContext 
{
    public TransformerConnectMEContext()
            : base("Name=TransformerANDConnectDB")
    {
        Database.SetInitializer<TransformerConnectMEContext>(new TransformerConnectMEContextInitializer());
    }
    public DbSet<User> Users { get; set; }
}

內部異常：

Answer 1

在連接字符串中將 Integrated Security 設置為 false。

當 Integrated Security 設置為 false 時，將在連接中指定用戶 ID 和密碼。 為 true 時，當前 Windows 帳戶憑據用於身份驗證
