SQL 服务器管理对象 (SMO) - user.Error 在生产服务器上登录失败

Question

我编写了一个代码，可以在单击按钮时备份数据库（生成 Sql 脚本），此代码 在本地主机上工作正常 ，但是当我部署时这对生产我得到以下错误。

Login failed for user 'XXXXXX\IWPD_1257(XXXXX)'

堆栈跟踪的一部分是

[ConnectionFailureException: Failed to connect to server ..]
   Microsoft.SqlServer.Management.Smo.DatabaseCollection.get_Item(String name) +370
   LeadWeb.Backup.scriptTables() +232
   LeadWeb.Backup.btnsubmit_OnClick(Object sender, EventArgs e) +5
   System.Web.UI.WebControls.Button.OnClick(EventArgs e) +9628114
   System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) +103
   System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10
   System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +35
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1724

这是我的代码

public void scriptTables()
        {
            try
            {
                string folder = HttpContext.Current.Server.MapPath("~/Excels/data.sql");// I have this file 
                System.IO.File.WriteAllText(folder, string.Empty);
                Server myServer = new Server(ConfigurationManager.AppSettings["server"]);
                Database CMSDB = myServer.Databases[ConfigurationManager.AppSettings["Database"]];

                Scripter script = new Scripter(myServer);
                ScriptingOptions so = new ScriptingOptions();
                so.AnsiPadding = true;
                so.IncludeHeaders = true;
                so.Default = true;
                so.DriForeignKeys = true;
                so.DriPrimaryKey = true;
                so.DriUniqueKeys = true;
                so.ScriptData = true;
                so.ScriptSchema = true;
                so.ScriptDrops = false;


                StringBuilder ss = new StringBuilder();

                foreach (Table table in CMSDB.Tables)
                {
                    string tables = table.Name;
                    string filename = folder;

                    so.FileName = filename;
                    so.AppendToFile = true;
                    CMSDB.Tables[tables].EnumScript(so);
                }
                HttpContext.Current.Response.Clear();
                HttpContext.Current.Response.ClearHeaders();
                HttpContext.Current.Response.ClearContent();
                HttpContext.Current.Response.AddHeader("Content-Disposition",
                    "attachment; filename=" + "LeadBackup" + DateTime.Now.Date.ToString("d") + ".sql");
                HttpContext.Current.Response.AddHeader("Content-Length", folder.Length.ToString());
                HttpContext.Current.Response.ContentType = "text/plain";
                HttpContext.Current.Response.Flush();
                HttpContext.Current.Response.TransmitFile(folder);
                HttpContext.Current.Response.End();

            }
            catch (Exception e)
            {

                Response.Write(e.Message);
            }

Webconfig 值

<add key="Server" value="." /> // changes according to server <add key="Database" value="Lead" /> // changes according to Database

任何帮助或指导。？

Answer 1

我的猜测是您的数据库连接字符串正在使用集成安全性，并且 XXXXXX\IWPD_1257(XXXXX) 未配置为访问数据库服务器 and/or 数据库。

在 SSMS 中，转到安全 > 登录并确定有权访问服务器的 windows 组。在活动目录中，将 XXXXXX\IWPD_1257(XXXXX) 添加到这些组之一。

或者，您可以直接添加 XXXXXX\IWPD_1257(XXXXX) 作为登录名。

无论采用哪种方法，请确保组或用户也已添加到数据库安全性中，并被授予访问所需角色的权限，以便从您需要的表中进行查询。

正如@jim 所说的那样，这是身份验证问题，我没有提供 SQL 服务器的登录 ID 和密码，经过一些研究我能够设法做到这一点，我正在发布代码未来 reference.Hope 它会对某人有所帮助 :)

public void scriptTables()
        {
            try
            {
                string folder = HttpContext.Current.Server.MapPath("~/Excels/data.sql");// I have this file 
                System.IO.File.WriteAllText(folder, string.Empty);

                ServerConnection serverConnection = new ServerConnection();
                serverConnection.LoginSecure = false;
                serverConnection.ServerInstance = ConfigurationManager.AppSettings["Server"];
                serverConnection.Login = ConfigurationManager.AppSettings["SmoUser"];
                serverConnection.Password = ConfigurationManager.AppSettings["SmoPass"];
                serverConnection.DatabaseName = ConfigurationManager.AppSettings["Database"];

                Server myServer = new Server(serverConnection);
                Database CMSDB = myServer.Databases[ConfigurationManager.AppSettings["Database"]];


                Scripter script = new Scripter(myServer);
                ScriptingOptions so = new ScriptingOptions();
                so.AnsiPadding = true;

                StringBuilder ss = new StringBuilder();

                foreach (Table table in CMSDB.Tables)
