SqlMembershipProvider Membership.GetUser名称失败

Question

这个问题 ,如果我使用GUID Membership.GetUser工作正常,但如果我尝试不带参数或名称失败:

//This works and adds records to aspnet_user & aspnet_Membership tables
MembershipUser membershipUser = Membership.CreateUser(_name, _pwd, _email, null, null, true, null, out createStatus); 

//These fail with an InvalidCastException
MembershipUser membershipUser2 = Membership.GetUser(_name, true);
MembershipUser membershipUser3 = Membership.GetUser();

//If I go look up the GUID for this user (userId), this works!
MembershipUser membershipUser4 = Membership.GetUser(new Guid("E1428CD3-CF17-494E-AB77-CF8F6010F585"), true);

其他之谜

//This works
Int32 count = Membership.GetNumberOfUsersOnline();    

//this fails (but totalRecords has the right value)
Int32 totalRecords;
MembershipUserCollection col = Membership.GetAllUsers(0,100, out totalRecords);

安装程序

• MVC
• .NET 4.0
• 默认SQL成员资格提供程序(无自定义或覆盖)

例如:

<membership defaultProvider="SqlProvider">
    <providers>
      <clear />
      <add name="SqlProvider" 
           type="System.Web.Security.SqlMembershipProvider" 
           connectionStringName="MyDB" 
           enablePasswordRetrieval="false" 
           enablePasswordReset="true" 
           requiresQuestionAndAnswer="false" 
           applicationName="myapp" 
           requiresUniqueEmail="false" 
           passwordFormat="Hashed" 
           maxInvalidPasswordAttempts="5" 
           minRequiredPasswordLength="2" 
           minRequiredNonalphanumericCharacters="0" 
           passwordAttemptWindow="10"
           passwordStrengthRegularExpression="" />
    </providers>
</membership>

• 标准的aspnet_*数据库表,没有自定义或额外的键
• aspnet_Membership_GetAllUsers从DB手动运行.重定向输出显示正在返回预期结果
• aspnet_Membership_GetUserByName也可以从数据库中运行

例外细节

Specified cast is not valid.
   at System.Data.SqlClient.SqlBuffer.get_SqlGuid()
   at System.Data.SqlClient.SqlDataReader.GetGuid(Int32 i)
   at System.Web.Security.SqlMembershipProvider.GetUser(String username, Boolean userIsOnline)
   at System.Web.Security.Membership.GetUser(String username, Boolean userIsOnline)

思考

这几乎就像Membership.GetUser方法中的错误一样.我为System.Web.dll(版本4.0)反映了System.Web.Security.SqlMembershipProvider.GetUser的代码,我得到以下内容:

public override MembershipUser GetUser(string username, bool userIsOnline)
{
  SecUtility.CheckParameter(ref username, true, false, true, 256, "username");
  SqlDataReader reader = (SqlDataReader) null;
  try
  {
    SqlConnectionHolder connectionHolder = (SqlConnectionHolder) null;
    try
    {
      connectionHolder = SqlConnectionHelper.GetConnection(this._sqlConnectionString, true);
      this.CheckSchemaVersion(connectionHolder.Connection);
      SqlCommand sqlCommand = new SqlCommand("dbo.aspnet_Membership_GetUserByName", connectionHolder.Connection);
      sqlCommand.CommandTimeout = this.CommandTimeout;
      sqlCommand.CommandType = CommandType.StoredProcedure;
      sqlCommand.Parameters.Add(this.CreateInputParam("@ApplicationName", SqlDbType.NVarChar, (object) this.ApplicationName));
      sqlCommand.Parameters.Add(this.CreateInputParam("@UserName", SqlDbType.NVarChar, (object) username));
      sqlCommand.Parameters.Add(this.CreateInputParam("@UpdateLastActivity", SqlDbType.Bit, (object) (bool) (userIsOnline ? 1 : 0)));
      sqlCommand.Parameters.Add(this.CreateInputParam("@CurrentTimeUtc", SqlDbType.DateTime, (object) DateTime.UtcNow));
      SqlParameter sqlParameter = new SqlParameter("@ReturnValue", SqlDbType.Int);
      sqlParameter.Direction = ParameterDirection.ReturnValue;
      sqlCommand.Parameters.Add(sqlParameter);
      reader = sqlCommand.ExecuteReader();
      if (!reader.Read())
        return (MembershipUser) null;
      string nullableString1 = this.GetNullableString(reader, 0);
      string nullableString2 = this.GetNullableString(reader, 1);
      string nullableString3 = this.GetNullableString(reader, 2);
      bool boolean1 = reader.GetBoolean(3);
      DateTime creationDate = reader.GetDateTime(4).ToLocalTime();
      DateTime lastLoginDate = reader.GetDateTime(5).ToLocalTime();
      DateTime lastActivityDate = reader.GetDateTime(6).ToLocalTime();
      DateTime lastPasswordChangedDate = reader.GetDateTime(7).ToLocalTime();
      Guid guid = reader.GetGuid(8);
      bool boolean2 = reader.GetBoolean(9);
      DateTime lastLockoutDate = reader.GetDateTime(10).ToLocalTime();
      return new MembershipUser(this.Name, username, (object) guid, nullableString1, nullableString2, nullableString3, boolean1, boolean2, creationDate, lastLoginDate, lastActivityDate, lastPasswordChangedDate, lastLockoutDate);
    }
    finally
    {
      if (reader != null)
        reader.Close();
      if (connectionHolder != null)
        connectionHolder.Close();
    }
  }
  catch
  {
    throw;
  }
}

下一步

我希望从SO人群那里得到一些方向,我应该去哪里.我想我可以覆盖这个方法并将我自己的提供程序放在一起只是为了调试它,或者我可以绕过这个darned的东西并直接调用DB.这看起来像一些基本的DB CRUD很多心痛.

当前状态

• 2013年3月5日:我今天早上发现我的aspnet_Users桌子有UserId一个nvarchar(256)而不是一个uniqueidentifier.也许SqlDataReader.GetGuid()是在那里窒息.今天晚上我会做一些测试,看看是不是问题.我想知道我的表结构是否已过时,因为在线文档将此字段显示为uniqueidentifier.

回答

我的 aspnet_User 和 aspnet_Membership 表设置UserId为nvarchar(256).

讨论

这似乎导致 SqlMembershipProvider.GetUser 方法中的以下行出现错误：

Guid guid = reader.GetGuid(8);

我从 .NET 框架 2 和 4 运行 aspnet_regsql.exe，并且都将 UserId 设置为唯一标识符，这让我认为我（毕竟）没有标准的 ASPNET DB。

对项目历史的一点挖掘表明，这个成员数据库最初是通过MySql的自定义提供程序生成的。我只能得出结论，当我们切换回默认提供程序时，它从未重新生成。

感谢大家的反馈。
