在调用“WebSecurity”类的任何其他方法之前，必须调用“WebSecurity.InitializeDatabaseConnection”方法
每次我用Visual Studio重新启动Debugging时，我都会遇到这个怪异的错误：
在调用“WebSecurity”类的任何其他方法之前，必须调用“WebSecurity.InitializeDatabaseConnection”方法。 此调用应放在站点根目录中的_AppStart.cshtml文件中。
但这是每次，当我将应用程序部署到prod时。 我随后在这里得到了这个错误。
我把正确的标签：
[Authorize(Roles = "admin")] [InitializeSimpleMembership] public class IndexController : Controller 到控制器，这是filter的方式。 它只是不想工作。
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(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); } } } } }
有人可以帮我解决这个问题吗？
从控制器中删除SimpleMemberShip属性并将其删除。 将以下内容添加到global.asax中。
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); } }
要简化Global.asax，可以将初始化代码放入class AuthConfig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(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，并从AccountController中删除它。 因为初始化是以懒惰的方式进行的..我只是想赶紧…它工作了!!!
通过为成员资格提供者和我的域模型使用单个上下文，我是一个聪明人。 事实certificate这就是问题所在; 您不能在单个上下文中使用成员资格提供程序和域类。
你需要有两个上下文。
要求只是调用WebSecurity Database Connection，您可以执行以下工作：
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，如错误消息所示。
@{WebMatrix.WebData.WebSecurity.InitializeDatabaseConnection("DefaultConnection", "TableName", "ColumnId", "ColumnName", autoCreateTables: false);}
