asp.net 4.5 自定义成员资格提供程序配置引发奇怪的异常 [英] asp.net 4.5 custom membership provider configuration throws strange exception

问题描述

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

My web site was initially written in MVC 4.0 RC using VS2010, . I have just downloaded and installed VS2012, and upgraded my project to Dotnet Framework 4.5.

在我的项目中，我使用了自定义 MemberShipProvider 和自定义 RoleProvider.在 VS2010 上，它就像一个魅力.但现在我不断收到一个奇怪的配置错误:

In my project I'm using a Custom MemberShipProvider and a custom RoleProvider. On VS2010 it worked like a charm. But now I'm keeping getting a strange Configuration Error:

无法在应用程序的预启动初始化阶段调用此方法."

"This method cannot be called during the application's pre-start initialization phase."

我的 web.config 中的system.web -> members -> providers -> add"行被标记为红色作为问题的根源.

The "system.web -> membership -> providers -> add" line in my web.config is marked red as the source of the problem.

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/角色提供程序，适当地更改 web.config，并发现问题与迁移过程有关，从而消除了怀疑错误再次出现！

I eliminated the suspicion that the problem has something to do with the migration process, by creating a new MVC 4.0 Project (in VS2012), adding my custom Membership/Role providers, changing the web.config appropriately, and finding that the error reappears!

深入研究问题 - 我在应用程序日志中发现了以下信息:

Digging deeper into the problem - I found the following information in the Application Log:

这是相关的自定义成员资格(我已经简化了它，但即使问题仍然存在)代码，只有ValidateUser被真正覆盖:

This is the relevant custom membership (I have simplified it, but even though the problem is still there) code, only ValidateUser is really overridden:

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:

This is the (simplified) 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;

        }

    }
}

推荐答案

我在自 MVC2 中使用我自己的自定义成员身份和角色提供程序，并在我从 MVC3 迁移到 4 时遇到了这个问题.

I use my own custom Membership and Role providers in Since MVC2 and ran into this issue when I migrated from MVC3 to 4.

我在 MVC4/.net4.5 EF5 中创建了一个新项目，但不幸遇到此错误.

I created a new project in MVC4 / .net4.5 EF5 and had the miss-fortune to encounter this error.

我设法通过执行以下操作来修复它:

I managed to fix it by doing the following:

将此添加到您的 webconfig appsettings:

Add this to your 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程序:

Add your connection string to your memberships and roles providers if not already set:

<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>

这为我解决了问题，希望对您有所帮助.

This resolved the issue for me and I hope it can help you.
