您必须调用“；WebSecurity.InitializeDatabaseConnection”；方法的任何其他方法之前

本文关键字：方法 任何 其他 InitializeDatabaseConnection 调用 WebSecurity | 更新日期: 2023-09-27 18:24:40

每次我用Visual Studio重新启动调试时，我都会收到这个奇怪的错误：

您必须调用"WebSecurity.InitializeDatabaseConnection"方法在调用"WebSecurity"类的任何其他方法之前。这调用应该放在地点

但每次都是这样，当我将应用程序部署到prod时。我会时不时地出现这个错误。

我确实贴上了正确的标签：

[Authorize(Roles = "admin")]
[InitializeSimpleMembership]
public class IndexController : Controller

到控制器，这是过滤器的样子。它就是不想工作。

using System;
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using System.Threading;
using System.Web.Mvc;
using MeetingTaskManagement.Models;
using WebMatrix.WebData;
namespace MeetingTaskManagement.Filters
{
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
    public sealed class InitializeSimpleMembershipAttribute : ActionFilterAttribute
    {
        private static SimpleMembershipInitializer _initializer;
        private static object _initializerLock = new object();
        private static bool _isInitialized;
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            // Ensure ASP.NET Simple Membership is initialized only once per app start
            LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
        }
        private class SimpleMembershipInitializer
        {
            public SimpleMembershipInitializer()
            {
                Database.SetInitializer<UsersContext>(null);
                try
                {
                    using (var context = new UsersContext())
                    {
                        if (!context.Database.Exists())
                        {
                            // Create the SimpleMembership database without Entity Framework migration schema
                            ((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
                        }
                    }
                    WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
                }
                catch (Exception ex)
                {
                    throw new InvalidOperationException("The ASP.NET Simple Membership database could not be initialized. For more information, please see http://go.microsoft.com/fwlink/?LinkId=256588", ex);
                }
            }
        }
    }
}

有人能帮我解决这个问题吗？

您必须调用“；WebSecurity.InitializeDatabaseConnection”；方法的任何其他方法之前

从控制器中删除SimpleMemberShip属性并将其丢弃。将以下内容添加到global.asax.

    private static SimpleMembershipInitializer _initializer;
    private static object _initializerLock = new object();
    private static bool _isInitialized;
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        AuthConfig.RegisterAuth();
        LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
    }
    public class SimpleMembershipInitializer
    {
        public SimpleMembershipInitializer()
        {
            using (var context = new UsersContext())
                context.UserProfiles.Find(1);
            if (!WebSecurity.Initialized)
                WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
        }
    }

为了简化您的Global.asax，您可以将初始化代码放入class AuthConfig中，如下所示：

public static class AuthConfig
{
    private static SimpleMembershipInitializer _initializer;
    private static object _initializerLock = new object();
    private static bool _isInitialized;
    public static void RegisterAuth()
    {
        // Ensure ASP.NET Simple Membership is initialized only once per app start
        LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
        // To let users of this site log in using their accounts from other sites such as Microsoft, Facebook, and Twitter,
        // you must update this site. For more information visit http://go.microsoft.com/fwlink/?LinkID=252166
        //OAuthWebSecurity.RegisterMicrosoftClient(
        //    clientId: "",
        //    clientSecret: "");
        //OAuthWebSecurity.RegisterTwitterClient(
        //    consumerKey: "",
        //    consumerSecret: "");
        //OAuthWebSecurity.RegisterFacebookClient(
        //    appId: "",
        //    appSecret: "");
        //OAuthWebSecurity.RegisterGoogleClient();
    }
    private class SimpleMembershipInitializer
    {
        public SimpleMembershipInitializer()
        {
            Database.SetInitializer<UsersContext>(null);
            try
            {
                using (var context = new UsersContext())
                {
                    if (!context.Database.Exists())
                    {
                        // Create the SimpleMembership database without Entity Framework migration schema
                        ((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
                    }
                }
                WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
            }
            catch (Exception ex)
            {
                throw new InvalidOperationException("The ASP.NET Simple Membership database could not be initialized. For more information, please see http://go.microsoft.com/fwlink/?LinkId=256588", ex);
            }
        }
    }
}

我只是将[InitializeSimpleMembership]切换到HomeController，并将其从AccountController中删除。因为初始化是以一种懒惰的方式进行的。。我只想赶时间……结果成功了！！！

通过为Membership提供者和我的域模型使用单个上下文，我成为了一个聪明人。事实证明，这就是问题所在；不能在单个上下文中使用Membership提供程序和域类。

你需要有两个上下文。

只需要调用WebSecurity数据库连接，您可以执行以下操作：

var WebSecDBContx = new UsersContext();
var CreatedByUser = WebSecDBContx.UserProfiles.Find(UserID);
string CreatedByUserName = CreatedByUser.UserName;

为什么不在项目根目录中创建_AppStart.cshtml，并将初始化代码放在那里作为错误消息状态。

@{WebMatrix.WebData.WebSecurity.InitializeDatabaseConnection("DefaultConnection", "TableName", "ColumnId", "ColumnName", autoCreateTables: false);}
