我正面临 "Your login attempt was not successful" 请重试。实现自定义成员资格时出错

Question

我对应用程序的要求是每个客户端的单个应用程序和多个数据库。所以我实现了自定义成员资格来实现这一点。首先，我根据该客户端数据库的连接字符串检查用户属于哪个客户端，我动态设置连接字符串并验证用户。

这是我的网络配置：

<membership defaultProvider="EPMembershipProvider" userIsOnlineTimeWindow="20">
  <providers>
    <clear />       
    <add name="EPMembershipProvider" type="EfficientPeople.GlobalClasses.EPMembershipProvider" connectionStringName="DBEntitiesConnectionString" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="25" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" applicationName="/" />
    <!--<add name="EPMembershipProvider" type="EfficientPeople.GlobalClasses.EPMembershipProvider, EfficientPeople"  connectionStringName="DBEntitiesConnectionString" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="25" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" applicationName="/" />-->
  </providers>
</membership>

<profile>
  <providers>
    <clear />
    <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="DBEntitiesConnectionString" applicationName="/" />
  </providers>
</profile>
<roleManager enabled="true">
  <providers>
    <clear />
    <add connectionStringName="DBEntitiesConnectionString" applicationName="/" name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" />
    <add applicationName="/" name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" />
  </providers>
</roleManager>

自定义会员 Class :

public class EPMembershipProvider : SqlMembershipProvider
{
    public override void Initialize(string name, System.Collections.Specialized.NameValueCollection config)
    {
        base.Initialize(name, config);
        // Update the private connection string field in the base class.  

        Int64 ClientId = Convert.ToInt64(HttpContext.Current.Session["_clientId"]);
        if (ClientId > 0)
        {
            UserLoginML objUL = new UserLoginML();

            //string _dbMembershipConnStr = ManageSessionFacade._dbMembershipConnStr;
            string _dbMembershipConnStr = HttpContext.Current.Session["_dbMembershipConnStr"].ToString();
            //string connectionString = ManageSessionVariable.Current._dbContextConnStr;

            if (_dbMembershipConnStr != "" && _dbMembershipConnStr != "db_not_validate" && _dbMembershipConnStr != "db_not_exist")
            {
                try
                {
                    // Set private property of Membership provider.  
                    //FieldInfo connectionStringField = GetType().BaseType.GetField("_sqlConnectionString", BindingFlags.Instance | BindingFlags.NonPublic);
                    //connectionStringField.SetValue(this, _dbMembershipConnStr);
                    FieldInfo connectionStringField = GetType().BaseType.GetField("_sqlConnectionString", BindingFlags.Instance | BindingFlags.NonPublic);
                    if (connectionStringField != null)
                        connectionStringField.SetValue(this, _dbMembershipConnStr);

                    //Set role provider
                    var roleField = Roles.Provider.GetType().GetField("_sqlConnectionString", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
                    if (roleField != null)
                        roleField.SetValue(Roles.Provider, _dbMembershipConnStr);

                    //Set Profile Provider

                    var profileField = ProfileManager.Provider.GetType().GetField("_sqlConnectionString", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
                    if (profileField != null)
                        profileField.SetValue(ProfileManager.Provider, _dbMembershipConnStr);
                }
                catch (Exception ex)
                {
                    throw ex;
                }

            }
        }
    }

当我运行在本地使用客户端 A 登录我的应用程序时 [DB1]-User1 登录成功。但是当我注销并尝试使用客户端 B [DB2] User2 登录时，它会抛出此错误消息：

Your login attempt was not successful

当我再次运行应用程序时，反之亦然。使用客户端 B[DB2]-User2 登录成功，但是当我在同一应用程序运行中尝试使用客户端 A[DB1]-User1 时，它会抛出相同的错误。但是我可以用客户端 B[DB2] 用户登录。

当我使用断点进行调试时，它在

处抛出错误

ValidateUser(string Username, string Passwd)

方法。返回 false 的 ValidateUser 方法。

我尝试了很多选项，但没有任何效果。请指导我。

Answer 1

问题出在 SqlMembership 的 Initialize 方法上。当用户第一次登录时，它调用初始化方法并设置连接字符串。当另一个用户尝试登录时，它使用相同的连接字符串。这就是为什么它没有验证。如果我们尝试调用 SqlMembershipProvider 的 Initialize 方法，它会抛出 "InvalidOperationException : membership provider already initialized."

的异常

所以我创建了我的自定义成员身份的对象，当我使用新创建的对象调用成员资格验证方法时，我能够设置我的连接字符串。

EPMembershipProvider myProvider = new EPMembershipProvider();
string configPath = "~/web.config";
Configuration config =     WebConfigurationManager.OpenWebConfiguration(configPath);
MembershipSection section = (MembershipSection)config.GetSection("system.web/membership");
ProviderSettingsCollection settings = section.Providers;
NameValueCollection membershipParams = settings[section.DefaultProvider].Parameters;
myProvider.Initialize("EPMembershipProvider", membershipParams);

bool Status = myProvider.ValidateUser(UserName, Password);

并且成功运行。感谢 Shri n 所有... :-)
