Question

我遇到了这个错误，我无法弄明白。我通过Chrome中的PostMan将数据发布到我的控制器，达到CreateUserAndAccount方法，并收到此错误：

To call this method, the "Membership.Provider" property must be an instance of "ExtendedMembershipProvider".

这是我的控制器：

[System.Web.Http.Authorize]
[InitializeSimpleMembership]
public class AccountController : ApiController
{
        // POST: /api/register
        [System.Web.Http.HttpPost]
        [System.Web.Http.AllowAnonymous]
        [ValidateAntiForgeryToken]
        //public HttpResponseMessage Register(RegisterModel model, string returnUrl)
        public HttpResponseMessage Register(RegisterModel model)
        {
            if (ModelState.IsValid)
            {
                // Attempt to register the user
                try
                {
                    WebSecurity.CreateUserAndAccount(model.UserName, model.Password); // blows up here
                    WebSecurity.Login(model.UserName, model.Password);

我使用相同的“InitializeSimpleMembershipAttribute”类作为MVC SPA模板：

{
    [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);
                }
            }
        }
    }
}

在我的web.config中，我启用了simpleMembership：

<add key="enableSimpleMembership" value="true" />

它还能做什么？

编辑：我刚刚尝试了此链接中的提示：

我现在正在

您必须调用“WebSecurity.InitializeDatabaseConnection”方法在调用“WebSecurity”类的任何其他方法之前。这个电话应放在站点根目录中的_AppStart.cshtml文件中。

任何建议都很棒。

我发现了问题。我在我的InitializeAttribute类中引用了System.Web.MVC ......应该是System.Web.Http。

要调用此方法，＆＃34; Membership.Provider＆＃34; property必须是＆＃34; ExtendedMembershipProvider＆＃34;的实例。
