comment configurer l'authentification Owin dans ASP.Net avec succès?

Question

Depuis 1 jour, j'essaye de configurer l'authentification basée sur le token pour mon projet basé sur api. Utiliser le lien ci-dessous comme point de départ.

http://www.c-sharpcorner.com/UploadFile/736ca4/token-based-authentication-in-web-api-2/

Mais je suis un peu confus & obtenir des erreurs.

Startup.cs (Situé dans le projet de bibliothèque de classe)

public class Startup 
{ 
    public void Configuration(IAppBuilder app) 
    { 
     var oauthProvider = new OAuthAuthorizationServerProvider 
     { 
      OnGrantResourceOwnerCredentials = async context => 
       { 
         var claimsIdentity = new ClaimsIdentity(context.Options.AuthenticationType); 
         claimsIdentity.AddClaim(new Claim("user", context.UserName)); 
         context.Validated(claimsIdentity); 
         return; 
        //context.Rejected(); 
       }, 

      OnValidateClientAuthentication = async context => 
       { 
        string clientId; 
        string clientSecret; 
        if(context.TryGetBasicCredentials(out clientId, out clientSecret)) 
        { 
         if(clientId == context.ClientId && clientSecret == "secretKey") 
         { 
          context.Validated(); 
         } 
        } 
       } 
     }; 

     var oauthOptions = new OAuthAuthorizationServerOptions 
     { 
      AllowInsecureHttp = true, 
      TokenEndpointPath = new PathString("/accesstoken"), 
      Provider = oauthProvider, 
      AuthorizationCodeExpireTimeSpan = TimeSpan.FromMinutes(1), 
      AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(3), 
      SystemClock = new SystemClock() 

     }; 

     app.UseOAuthAuthorizationServer(oauthOptions); 
     app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions()); 

     var config = new HttpConfiguration(); 
     config.MapHttpAttributeRoutes(); 
     app.UseWebApi(config); 
    } 
} 

Controller API

[AcceptVerbs("POST")] 
    [HttpPost] 
    public string Post([FromBody]User user) 
    { 
     if(user.Username == "chetan" && user.Password == "pwd") 
     { 
      HttpClient client = new HttpClient(); 
      OAuth.InitOAuth(client, user.Username, user.Password); 
      return "Success!!User valid for token"; 
     } 
     else 
     { 
      return "Error!! User invalid"; 
     } 
    } 

Ma classe OAuth

public class OAuth 
{ 
    public static void InitOAuth(HttpClient client, string userName, string password) 
    { 
     string baseAddress = "http://localhost:9000/"; 
     // GETTING THE ERROR AT THIS LINE 
     using (WebApp.Start<Startup>(url: baseAddress)) 
     { 
      var form = new Dictionary<string, string> 
      { 
       {"grant_type", "password"}, 
       {"username", userName }, 
       {"password", password}, 
      }; 

      var tokenResponse = client.PostAsync(baseAddress + "accesstoken", new FormUrlEncodedContent(form)).Result; 
      var token = tokenResponse.Content.ReadAsAsync<Token>(new[] { new JsonMediaTypeFormatter() }).Result; 
      client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token.AccessToken); 

     } 
    } 
} 

Erreur: -

Could not load file or assembly 'Microsoft.Owin, Version=2.0.2.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Sur googler je suis arrivé quelques liens & installé le package suivant: -

Install-package Microsoft.Owin.Host.HttpListener 

Web.Config

<dependentAssembly> 
    <assemblyIdentity name="Microsoft.Owin" publicKeyToken="Secretkey" culture="neutral" /> 
    <bindingRedirect oldVersion="0.0.0.0-3.0.1.0" newVersion="3.0.1.0" /> 
    </dependentAssembly> 

Ce que je suis absent ici?

Toute aide ou suggestion très appréciée. Merci.

Answer 1

Peut-être problème est:

publicKeyToken="Secretkey" 

Vous avez essayer de changer:

<dependentAssembly> 
    <assemblyIdentity name="Microsoft.Owin" publicKeyToken="31bf3856ad364e35" /> 
    <bindingRedirect oldVersion="0.0.0.0-3.0.1.0" newVersion="3.0.1.0" /> 
</dependentAssembly> 

Answer 2

Vous pouvez mettre à jour ces références à la dernière version:

Install-Package Microsoft.Owin -Version 3.0.1.0 
Install-Package Microsoft.Owin.Security -Version 3.0.1.0 

et votre web.config Pourrait être: -

<runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
     <dependentAssembly> 
     <assemblyIdentity name="Microsoft.Owin.Security" publicKeyToken="31bf3856ad364e35" /> 
     <bindingRedirect oldVersion="0.0.0.0-3.0.1.0" newVersion="3.0.1.0" /> 
     </dependentAssembly> 
     <dependentAssembly> 
     <assemblyIdentity name="Microsoft.Owin" publicKeyToken="31bf3856ad364e35" /> 
     <bindingRedirect oldVersion="0.0.0.0-3.0.1.0" newVersion="3.0.1.0" /> 
     </dependentAssembly> 
    </assemblyBinding> 
    </runtime> 

Espérons que cela fonctionne !!!
