c# - 实体类型 ApplicationUser 不是当前上下文模型的一部分

Question

我在 Asp.net 中有一个 Web 应用程序，首先使用 Entity Framework 6 和数据库。用户连接时遇到问题。这是我的代码:

Web.config

 <connectionStrings>
  <add name="DefaultConnection" connectionString="data source=MyServer\MyDataBase;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=MyServer\MyDataBase;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=MyServer\MyDataBase;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=MyServer\MyDataBase;initial catalog=Cliniciel_WebRV_Master;user id=XXX;password=XXXX;multipleactiveresultsets=True;application name=EntityFramework&quot;" providerName="System.Data.EntityClient" />          
 </connectionStrings>

这里我使用连接字符串“Cliniciel_WebRV_Oauth”进行身份验证。

我在启动时配置我的 oauthToken

Startup.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)
                    }
                });
        }

    {

        public ApplicationDbContext()
            : base("Cliniciel_WebRV_Oauth", throwIfV1Schema: false)
        {
            Configuration.ProxyCreationEnabled = false;
            Configuration.LazyLoadingEnabled = false;
        }

        [WebMethod(EnableSession = true)]
        public static ApplicationDbContext Create()
        {
            return new ApplicationDbContext();
        }

    }
}

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:

The ApplicationUser entity type is not part of the model for the current context.

这是痕迹:

Ligne 32 : var userManager = context.OwinContext.GetUserManager(); Ligne 33 : Ligne 34 : ApplicationUser user = await userManager.FindAsync(context.UserName, context.Password); Ligne 35 : Ligne 36 : if (user == null)

Answer 1

你的 ApplicationUserManager 方法在哪里

你需要像这样通过传递 DbContext 来配置 Application 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>()));
