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.
