Benim SimpleRefreshTokenProvider sınıfı kodu şu şekildedir:

public class Startup 
    { 
     public void Configuration(IAppBuilder app) 
     { 
      HttpConfiguration config = new HttpConfiguration(); 

      ConfigureOAuth(app); 

      WebApiConfig.Register(config); 
      app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll); 
      app.UseWebApi(config); 
     } 

     public void ConfigureOAuth(IAppBuilder app) 
     { 

      OAuthAuthorizationServerOptions oAuthServerOptions = new OAuthAuthorizationServerOptions() 
      { 

       AllowInsecureHttp = true, 
       TokenEndpointPath = new PathString("/token"), 
       AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(30), 
       Provider = new SimpleAuthorizationServerProvider(), 
       RefreshTokenProvider = new SimpleRefreshTokenProvider() 
      }; 

      // Token Generation 
      app.UseOAuthAuthorizationServer(oAuthServerOptions); 
      app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions()); 

     } 
    } 

Benim SimpleAuthorizationServerProvider sınıfı kodu şu şekildedir:

My Başlangıç ​​sınıfı kodudur AuthRepository sınıf kodu aşağıdaki gibidir:

public class AuthRepository : IDisposable 
    { 
     private AuthContext _ctx; 

     private UserManager<IdentityUser> _userManager; 

     public AuthRepository() 
     { 
      _ctx = new AuthContext(); 
      _userManager = new UserManager<IdentityUser>(new UserStore<IdentityUser>(_ctx)); 
     } 

     public async Task<IdentityResult> RegisterUser(UserModel userModel) 
     { 
      IdentityUser user = new IdentityUser 
      { 
       UserName = userModel.UserName 
      }; 

      var result = await _userManager.CreateAsync(user, userModel.Password); 

      return result; 
     } 

     public async Task<IdentityUser> FindUser(string userName, string password) 
     { 
      IdentityUser user = await _userManager.FindAsync(userName, password); 

      return user; 
     } 


     public Client FindClient(string clientId) 
     { 
      var client = _ctx.Clients.Find(clientId); 
      //var clients = _ctx.Clients; 
      //var client = _ctx.Clients.FirstOrDefault(x => x.Id==clientId); 
      return client; 
     } 

     public async Task<bool> AddRefreshToken(RefreshToken token) 
     { 

      var existingToken = _ctx.RefreshTokens.Where(r => r.Subject == token.Subject && r.ClientId == token.ClientId).SingleOrDefault(); 

      if (existingToken != null) 
      { 
       var result = await RemoveRefreshToken(existingToken); 
      } 

      _ctx.RefreshTokens.Add(token); 

      return await _ctx.SaveChangesAsync() > 0; 
     } 

     public async Task<bool> RemoveRefreshToken(string refreshTokenId) 
     { 
      var refreshToken = await _ctx.RefreshTokens.FindAsync(refreshTokenId); 

      if (refreshToken != null) 
      { 
       _ctx.RefreshTokens.Remove(refreshToken); 
       return await _ctx.SaveChangesAsync() > 0; 
      } 

      return false; 
     } 

     public async Task<bool> RemoveRefreshToken(RefreshToken refreshToken) 
     { 
      _ctx.RefreshTokens.Remove(refreshToken); 
      return await _ctx.SaveChangesAsync() > 0; 
     } 

     public async Task<RefreshToken> FindRefreshToken(string refreshTokenId) 
     { 
      var refreshToken = await _ctx.RefreshTokens.FindAsync(refreshTokenId); 

      return refreshToken; 
     } 

     public List<RefreshToken> GetAllRefreshTokens() 
     { 
      return _ctx.RefreshTokens.ToList(); 
     } 


     public void Dispose() 
     { 
      _ctx.Dispose(); 
      _userManager.Dispose(); 

     } 
    } 

Ve ajax kodu: Ben Yenile tıklayın Nihayet

$("#refresh").click(function() { 
       var token = sessionStorage.getItem(tokenKey); 
       var refresh = sessionStorage.getItem('isRefreshToken'); 
       var refreshToken = sessionStorage.getItem('refreshToken'); 

       if (refresh) { 
        var refreshdata = "grant_type=refresh_token&refresh_token=" + refreshToken + "&client_id=TokenBasedAuthentication"; 
        console.log(refreshdata); 

        sessionStorage.setItem(tokenKey, ''); 
        sessionStorage.setItem(isRefreshToken, ''); 
        sessionStorage.setItem(refreshToken, ''); 

        $.ajax({ 
         url: '/token', 
         type: 'POST', 
         data: refreshdata, 
         headers: { 'Content-Type': 'application/x-www-form-urlencoded' }, 
         success: function (data) { 

          sessionStorage.setItem(tokenKey, data.access_token); 
          sessionStorage.setItem(isRefreshToken, true); 
          sessionStorage.setItem(refreshToken, data.refresh_token); 

         }, 
         error: function (xhr) { 
          alert(xhr.status + ': ' + xhr.statusText); 
         } 

        }); 
       } 

      }); 

o hatayı bana aşağıdaki hata verir: "invalid_grant"

denedim

Son iki gün anlamaya ama başarısız oldu.

Answer 1

Bunu deneyin. newIdentity.AddClaim(new Claim("newClaim", "newValue")); kod satırını sınıfının GrantRefreshToken işlevinden kaldırın. Bu hat kullanılmadığı için. Yeni yenileme belirteci isteğinde bulunduğunuzda bu talebi çoğaltıyor. Yani sana karşı çıkıyor.

Answer 2

refresh_token öğesinin geçerli olduğunu bilsem de her zaman bir geçersiz_grant hatası aldığım bir sorunla karşılaştım. Geçersiz_grant hatası olabileceğinin bir çok nedeni var, ancak kodda hata ayıkladıktan sonra, sorunumun CreateAsync yönteminde olduğunu keşfettim. RefreshTokenLifetime değişkeni null. Böylece, RefreshToken oluşturulduğunda, ExpiresUtc değeri geçersiz ve geçersiz_grant hatasına neden oluyor. Bunu çözmek için refreshTokenLifetime değişkeni için geçerli bir değere sahip olduğumu doğruladım.

var refreshTokenLifetime = context.OwinContext.Get<string>("as:RefreshTokenLifetime") ?? "60";
