实体类型ApplicationUser不属于当前上下文的模型

我在Asp.net中有一个web应用程序，首先是Entity Framework 6和数据库。当用户连接时，我遇到了问题。这是我的代码：

Web.config

<connectionStrings>
<add name="DefaultConnection" connectionString="data source=MyServerMyDataBase;initial catalog=Cliniciel_WebRV_Master;User Id=XXX;Password=XXXX" providerName="System.Data.SqlClient" />
<add name="Cliniciel_WebRV_MasterEntities" connectionString="metadata=res://*/Models.Entities.Cliniciel_WebRV_Master.csdl|res://*/Models.Entities.Cliniciel_WebRV_Master.ssdl|res://*/Models.Entities.Cliniciel_WebRV_Master.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=MyServerMyDataBase;initial catalog=Cliniciel_WebRV_Master;user id=XXX;password=XXXX;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
<add name="Cliniciel_WebRV_Entities" connectionString="metadata=res://*/Models.Entities.Cliniciel_WebRV_Entities.csdl|res://*/Models.Entities.Cliniciel_WebRV_Entities.ssdl|res://*/Models.Entities.Cliniciel_WebRV_Entities.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=MyServerMyDataBase;initial catalog=Cliniciel_WebRV_DEV;user id=XXX;password=XXXX;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
<add name="Cliniciel_WebRV_Oauth" connectionString="metadata=res://*/Models.Entities.Cliniciel_WebRV_Oauth.csdl|res://*/Models.Entities.Cliniciel_WebRV_Oauth.ssdl|res://*/Models.Entities.Cliniciel_WebRV_Oauth.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=MyServerMyDataBase;initial catalog=Cliniciel_WebRV_Master;user id=XXX;password=XXXX;multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" />          
</connectionStrings>

在这里，我使用连接字符串"Cliniel_WebRV_Oauth"进行身份验证。

我在启动时配置我的oauthToken

启动.cs

private void ConfigureOAuthTokenGeneration(IAppBuilder app)
{
//// Configure the db context and user manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
//app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);
OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
{
//For Dev enviroment only (on production should be AllowInsecureHttp = false)
#if DEBUG
AllowInsecureHttp = true,
#endif
TokenEndpointPath = new PathString("/oauth/token"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
Provider = new CustomOAuthProvider(),
AccessTokenFormat = new CustomJwtFormat("http://localhost:55555/")
};
// OAuth 2.0 Bearer Access Token Generation
app.UseOAuthAuthorizationServer(OAuthServerOptions);
}
private void ConfigureOAuthTokenConsumption(IAppBuilder app)
{
var issuer = "http://localhost:55555/";
string audienceId = ConfigurationManager.AppSettings["as:AudienceId"];
byte[] audienceSecret = TextEncodings.Base64Url.Decode(ConfigurationManager.AppSettings["as:AudienceSecret"]);
// Api controllers with an [Authorize] attribute will be validated with JWT
app.UseJwtBearerAuthentication(
new JwtBearerAuthenticationOptions
{
AuthenticationMode = AuthenticationMode.Active,
AllowedAudiences = new[] { audienceId },
IssuerSecurityTokenProviders = new IIssuerSecurityTokenProvider[]
{
new SymmetricKeyIssuerSecurityTokenProvider(issuer, audienceSecret)
}
});
}

应用程序DBContext.cs

using Microsoft.AspNet.Identity.EntityFramework;
using System;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.SessionState;
using WebRV.Models.Entities;
namespace WebRV.Infrastructure
{
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>  //DOIT CREER APPLICATION USER.
{
public ApplicationDbContext()
: base("Cliniciel_WebRV_Oauth", throwIfV1Schema: false)
{
Configuration.ProxyCreationEnabled = false;
Configuration.LazyLoadingEnabled = false;
}
[WebMethod(EnableSession = true)]
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
}
}

CustomOAuthProvider.cs

using System;
using System.Linq;
using WebRV.Infrastructure;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.OAuth;
using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNet.Identity.Owin;
using System.Web.Mvc;
using WebRV.Models.Entities;
using System.Net;
using System.Web.Http;

namespace WebRV.Providers
{
public class CustomOAuthProvider : OAuthAuthorizationServerProvider
{
[ValidateAntiForgeryToken]
public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
{
context.Validated();
return Task.FromResult<object>(null);
}
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
var allowedOrigin = "*";
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { allowedOrigin });
var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();
ApplicationUser user = await userManager.FindAsync(context.UserName, context.Password);
if (user == null)
{
context.SetError("invalid_grant", "The user name or password is incorrect.");
}
else
{
//if (!user.EmailConfirmed)
//{
//    context.SetError("invalid_grant", "User did not confirm email.");
//    return;
//}

ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager, "JWT");
var ticket = new AuthenticationTicket(oAuthIdentity, null);
context.Validated(ticket);
}
}
}
}

这是我得到的错误：

ApplicationUser实体类型不是当前上下文。

这是跟踪：

Ligne 32:var用户管理器=上下文OwinContext.GetUserManager()；木质素33：Ligne 34:ApplicationUser user=等待userManager.FindAsync(context.UserName，context.Password)；木质素35：Ligne 36:if(user==null)

ApplicationUserManager方法在哪里

您需要像这样通过传递DbContext 来配置应用程序UserManager

public class ApplicationUserManager : UserManager<ApplicationUser>
{
public ApplicationUserManager(IUserStore<ApplicationUser> store)
: base(store)
{
}
public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
{
var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<EducationContext>()));
// Configure validation logic for usernames
manager.UserValidator = new UserValidator<ApplicationUser>(manager)
{
AllowOnlyAlphanumericUserNames = false,
RequireUniqueEmail = true
};
// Configure validation logic for passwords
manager.PasswordValidator = new PasswordValidator
{
RequiredLength = 6,
RequireNonLetterOrDigit = true,
RequireDigit = true,
RequireLowercase = true,
RequireUppercase = true,
};
// Configure user lockout defaults
manager.UserLockoutEnabledByDefault = true;
manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
manager.MaxFailedAccessAttemptsBeforeLockout = 5;
// Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user
// You can write your own provider and plug it in here.
manager.RegisterTwoFactorProvider("Phone Code", new PhoneNumberTokenProvider<ApplicationUser>
{
MessageFormat = "Your security code is {0}"
});
manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser>
{
Subject = "Security Code",
BodyFormat = "Your security code is {0}"
});
manager.EmailService = new EmailService();
manager.SmsService = new SmsService();
var dataProtectionProvider = options.DataProtectionProvider;
if (dataProtectionProvider != null)
{
manager.UserTokenProvider = 
new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
}
return manager;
}
}

最重要的是写这一行(Create方法中的第一行)

var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<EducationContext>()));
