c# – 实体类型ApplicationUser不是当前上下文的模型的一部分

C# 前端之家
前端之家收集整理的这篇文章主要介绍了c# – 实体类型ApplicationUser不是当前上下文的模型的一部分，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我在 Asp.net中有一个带有Entity Framework 6和数据库的Web应用程序.当用户连接时,我遇到了问题.这是我的代码：

Web.config文件

<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>

在这里,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)
                    }
                });
        }

ApplicationDBContext.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：

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

这是跟踪：

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)

解决方法

ApplicationUserManager方法在哪里？

您需要通过传递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>()));
