asp.net 4.5自定义成员资格提供程序配置抛出奇怪的异常

标签: asp.net asp.net-mvc-4 visual-studio-2012 .net-4.5

我的网站最初是使用VS2010在MVC 4.0 RC中编写的。 我刚下载并安装了VS2012,并将我的项目升级到Dotnet Framework 4.5。

在我的项目中,我正在使用Custom MemberShipProvider和自定义RoleProvider。在VS2010上,它就像一个魅力。但现在我一直在收到一个奇怪的配置错误:

“在应用程序的预启动初始化阶段,无法调用此方法。”

我的web.config中的“system.web - >成员资格 - >提供商 - >添加”行标记为红色,作为问题的根源。

我通过创建一个新的MVC 4.0项目(在VS2012中),添加我的自定义成员资格/角色提供程序,适当地更改web.config以及发现该问题,消除了对该问题与迁移过程有关的怀疑。错误再次出现!

深入研究问题 - 我在应用程序日志中找到了以下信息:

这是相关的自定义成员资格(我已将其简化,但即使问题仍然存在)代码,只有ValidateUser才被覆盖:

using System;
using System.Linq;
using System.Web.Security;
using DAL.MyWebSite;

namespace MyWebSite.Security
{
    public class MyWebSiteMembershipProvider : MembershipProvider
    {




        /// <summary>
        /// Verifies that the specified user name and password exist in the data source.
        /// </summary>
        /// <returns>
        /// true if the specified username and password are valid; otherwise, false.
        /// </returns>
        /// <param name="username">The name of the user to validate. </param><param name="password">The password for the specified user. </param>
        public override bool ValidateUser(string username, string password)
        {
            // simplified
            return true;
        }



    }
}

这是(简化的)RoleProvider:

using System;
using System.Linq;
using System.Web.Security;
using DAL.MyWebSite;

namespace MyWebSite.Security
{
    public class MyWebSiteRoleProvider : RoleProvider
    {


        //readonly MyWebSiteDbContext _context = new MyWebSiteDbContext();
        /// <summary>
        /// Gets a value indicating whether the specified user is in the specified role for the configured applicationName.
        /// </summary>
        /// <returns>
        /// true if the specified user is in the specified role for the configured applicationName; otherwise, false.
        /// </returns>
        /// <param name="username">The user name to search for.</param><param name="roleName">The role to search in.</param>
        public override bool IsUserInRole(string username, string roleName)
        {
            return true;
            //return GetRolesForUser(username).Contains(roleName);
        }

        /// <summary>
        /// Gets a list of the roles that a specified user is in for the configured applicationName.
        /// </summary>
        /// <returns>
        /// A string array containing the names of all the roles that the specified user is in for the configured applicationName.
        /// </returns>
        /// <param name="username">The user to return a list of roles for.</param>
        public override string[] GetRolesForUser(string username)
        {
            return new string[] {"one", "two"};

            //var sm = _context.SalesManagers.Include("PermissionLevel").FirstOrDefault(manager => manager.UserName == username);

            //if (sm != null)
            //{
            //    if (sm.PermissionLevel.Name == "Sales Manager")
            //    {
            //        return new[] { "SalesManagers" };
            //    }

            //    if (sm.PermissionLevel.Name == "Administrator")
            //    {
            //        return new[] { "SalesManagers", "Administrators" };
            //    }

            //} 
            //return null;

        }

    }
}

我在自MVC2中使用自己的自定义成员资格和角色提供程序,并在从MVC3迁移到4时遇到此问题。

我在MVC4 / .net4.5 EF5中创建了一个新项目,并且遇到了这个错误。

我设法通过执行以下操作来修复它:

将此添加到您的webconfig appsettings:

  <appSettings>
    <add key="enableSimpleMembership" value="false"/>
    <add key="autoFormsAuthentication" value="false"/>
  </appSettings>

如果尚未设置,请将您的连接字符串添加到您的成员资格和角色提供者:

<membership defaultProvider="MyMembershipProvider">
  <providers>
    <add name="MyMembershipProvider" type="AMS.WebUI.Infrastructure.CustomMembershipProvider" connectionStringName="EFDbContext" />
  </providers>
</membership>
<roleManager defaultProvider="MyRoleprovider">
  <providers>
    <add name="MyRoleprovider" type="AMS.WebUI.Infrastructure.CustomRoleProvider" connectionStringName="EFDbContext" />
  </providers>
</roleManager>

这解决了我的问题,我希望它可以帮到你。

好的,让我们看看我是否可以解释这一点。 ASP.NET 4引入了一个新的程序集级属性:PreApplicationStartMethodAttribute,通常在Properties/AssemblyInfo.cs文件中使用。

ASP.NET MVC 4标准模板附带对WebMatrix.WebData程序集的引用。查看its code,AssemblyInfo确实有这个:

[assembly: PreApplicationStartMethod(typeof(PreApplicationStartCode), "Start")]

所以基本上,在调用App_Start之前,框架将调用WebMatrix.WebData.PreApplicationStartCode.Start(),除其他外,它会执行此操作

// Initialize membership provider
WebSecurity.PreAppStartInit();

果然,就像@Ben Pretorius所说,这种方法就像这样开始

internal static void PreAppStartInit()
{
    // Allow use of <add key="EnableSimpleMembershipKey" value="false" /> to disable registration of membership/role providers as default.
    if (ConfigUtil.SimpleMembershipEnabled)
    {
        ...

所以你有这个“自动”失败的方式/原因。微软没有在标准的Web.config中包含<add key="EnableSimpleMembershipKey" value="true" />以使其更加明显“嘿,这里有设置的SimpleProvider东西”,这真的太糟糕了。

答案 2 :(得分:8)

我也在讨论这个问题并查看WebMatrix代码,最后我认为Ben的解决方案似乎是有效的。

(我也尝试过使用程序集引用而没有成功。我认为删除你刚刚实现的配置与配置设置相同 - WebMatrix安全性没有正确初始化。但我认为这是非常危险的但是我只是在这里猜测。)

所以对我来说有用:

<appSettings>
  <add key="enableSimpleMembership" value="false"/>
</appSettings>

<membership defaultProvider="MyMembershipProvider">
  <providers>
    <clear />
    <add name="MyMembershipProvider" type="MyNamespace.MyMembershipProvider" />
  </providers>
</membership>
<!-- this role configuration below uses the SimpleRoleProvider, because I just 
     wanted to replace the membership provider. If you need to replace that one 
     too, just use your own class instead. -->
<roleManager enabled="true" defaultProvider="AspNetSqlRoleProvider">
  <providers>
    <remove name="AspNetSqlRoleProvider" />
    <add name="AspNetSqlRoleProvider" type="WebMatrix.WebData.SimpleRoleProvider, WebMatrix.WebData, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    <!-- note: WebMatrix registers SimpleRoleProvider with name
         'AspNetSqlRoleProvider'. I don't know why but i kept it. -->
  </providers>
</roleManager>

我检查了WebMatrix代码,似乎将'enableSimpleMembership'设置为false是非常无害的。 WebMatrix仅使用它来初始化成员资格/角色提供者(可以由上面的配置代替),并且它允许表单身份验证允许替代配置方式(通过应用程序设置) - 如果您有标准表单,这也没有必要验证配置正确(主要是'loginUrl'是这里唯一重要的播放器)。

我还尝试检查'autoFormsAuthentication'设置的作用 - 但我没有找到任何内容,所以只是跳过它。看起来还不错。

答案 3 :(得分:2)

我已经解决了这个问题。我发现在VS2012中创建MVC 4项目时,模板会添加对某些程序集的引用,其中包括:webmatrix和Oauth ...... 我刚刚删除了这些引用,问题就消失了。我不知道如何解决这个问题,但我看到Exception来自WebMatrix程序集,因此我试图删除它。对不起,我没有时间投资调查......
