Question

我为我的应用程序创建角色，我将此角色添加到web.config中，如您所见：

正如您所看到的，这部分代码是我的角色：

<roleManager defaultProvider="CustomRoleProvider" enabled="true" cacheRolesInCookie="false">
      <providers>
        <clear />
        <add name="CustomRoleProvider" type="EducationMVC.Infrastructure.MyRoleProvider"  />
      </providers>
    </roleManager>

所以跑完后我得到这个错误：

配置部分'system.web / roleManager'已经定义。部分必须每个配置文件只出现一次。请参阅帮助主题例外HTTP错误500.19 - 内部服务器错误请求页面无法访问，因为相关的配置数据为页面无效

web.config的这一部分是亮点：

   47:     <roleManager defaultProvider="CustomRoleProvider" enabled="true" cacheRolesInCookie="false">

造成这种情况的原因是什么？

这是我定义的角色：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;
using EducationModel;

namespace EducationMVC.Infrastructure
{

    public class MyRoleProvider:RoleProvider
    {
       private readonly EducationDBEntities _dbcontext = new EducationDBEntities();

        public override void AddUsersToRoles(string[] usernames, string[] roleNames)
        {
            throw new NotImplementedException();
        }

        public override string ApplicationName
        {
            get
            {
                throw new NotImplementedException();
            }
            set
            {
                throw new NotImplementedException();
            }
        }

        public override void CreateRole(string roleName)
        {
            throw new NotImplementedException();
        }

        public override bool DeleteRole(string roleName, bool throwOnPopulatedRole)
        {
            throw new NotImplementedException();
        }

        public override string[] FindUsersInRole(string roleName, string usernameToMatch)
        {
            throw new NotImplementedException();
        }

        public override string[] GetAllRoles()
        {
            throw new NotImplementedException();
        }


        public override string[] GetRolesForUser(string username)
        {

            var objUser = _dbcontext.Users.FirstOrDefault(x => x.AppUserName == username);
            if (objUser == null)
            {
                return null;
            }
            else
            {
                string[] ret = objUser.Roles.Select(x => x.RoleName).ToArray();
                return ret;
            }

        }


        public override string[] GetUsersInRole(string roleName)
        {
            throw new NotImplementedException();
        }

        public override bool IsUserInRole(string username, string roleName)
        {
            throw new NotImplementedException();
        }

        public override void RemoveUsersFromRoles(string[] usernames, string[] roleNames)
        {
            throw new NotImplementedException();
        }

        public override bool RoleExists(string roleName)
        {
            throw new NotImplementedException();
        }
    }
}

Answer 1

但由于错误是一个自我解释的错误，删除此行

<roleManager enabled="true" />

Answer 2

我只是将这些行添加到我的web.config

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

Answer 3

不同情况：


使用IIS 7 / 7.5时通常会发生此错误，因为在更高版本的IIS中未使用通配符（。）。*   通过删除MIME类型条目“。*”或将其替换为“
来解决此问题
我们将虚拟目录的权限授予默认用户，以免出现错误。 我们将虚拟目录的权限授予默认用户，   我们应该将应用程序池标识设置为默认用户，然后将其   现在工作正常。

出现此问题的原因是Application Host.config文件或Web.config文件包含格式错误的XML元素。 删除   格式不正确的XML元素，来自ApplicationHost.config文件或   Web.config文件。   如果会话时间状态创建问题，则将此代码添加到web.config文件

如果发生IIS配置错误...如何解决此问题


在运行时键入inetmgr以打开IIS。

从“网站”面板中选择您的网站。

对于该站点，单击右侧“操作”面板中的“编辑权限”链接。

现在将打开一个新的属性窗口。

从“属性”窗口中选择“安全性”选项卡。

从“组”或用户名中选择用户。

现在单击所选用户的“编辑”按钮。

如果选中了任何列出的拒绝复选框，则将其删除。

根据您所需的权限级别。

<system.web>
     <authentication mode="Forms">
           <forms loginUrl="~/Page.aspx" timeout="2000"/>
     </authentication>

将Rolemanager添加到配置文件会导致HTTP错误500.19 - 内部服务器错误
