OAuth承載令牌無效

Question

我有一個auth-provider的最小設置，它設置了聲明身份

public class SimpleAuthorizationProvider : OAuthAuthorizationServerProvider
{
    public override async Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        context.Validated();
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        if (context.UserName != context.Password)
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
            return;
        }

        var identity = new ClaimsIdentity(context.Options.AuthenticationType);
        identity.AddClaim(new Claim("sub", context.UserName));
        identity.AddClaim(new Claim("role", "user"));

        context.Validated(identity);
    }
}

我正在嘗試訪問hello-world-api，這會給出未經授權的訪問錯誤。

public class HelloWorldApiController : ApiController
{

    [HttpGet]
    [Route("api/hello")]
    //[AllowAnonymous]
    [Authorize]
    public HttpResponseMessage FetchAllEnum()
    {
        return Request.CreateResponse(HttpStatusCode.OK, "Hello World!!!");
    }
}

但我正在獲得上述API的401 /未經授權的訪問權限。 我確實將持有者令牌返回給web-api，我也將它作為Bearer ABCD****傳遞給服務器。 我確實看到在Visual Studio中調試時設置了授權標頭。

如果我調試AuthorizeAttribute ，我得到user.Identity.IsAuthenticated為false ，這實際上導致了問題。 但鑒於我確實看到了Authorization標頭集並且我在OAuthProvider設置了聲明詳細信息，為什么AuthorizeAttribute沒有讀取該信息？

注意：這是一個Web API項目，因此沒有對MVC AuthorizeAttribute的引用。

這是OWIN設置：

public static class WebApiConfig
{
    public static HttpConfiguration Register()
    {
        var config = new HttpConfiguration();
        config.MapHttpAttributeRoutes();
        //config.SuppressDefaultHostAuthentication(); //tried with/without this line
        config.Filters.Add(new AuthorizeAttribute());
        config.EnableCors(new EnableCorsAttribute("*", "*", "*", "*"));
        return config;
    }
}

public class OwinConfiguration
{
    // ReSharper disable once UnusedMember.Local
    public void Configuration(IAppBuilder app)
    {
        ConfigureOAuth(app);
        app.UseCors(CorsOptions.AllowAll);
        app.UseWebApi(WebApiConfig.Register());
    }

    private void ConfigureOAuth(IAppBuilder app)
    {
        var options = new OAuthAuthorizationServerOptions
        {
            AllowInsecureHttp = true,
            TokenEndpointPath = new PathString("/token"),
            AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(60),
            Provider = new SimpleAuthorizationProvider()
        };

        app.UseOAuthAuthorizationServer(options);
        app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
    }
}

Answer 1

使其工作config.Filters.Add(new HostAuthenticationAttribute("bearer")); 需要添加此行beofre authorize屬性...

public static HttpConfiguration Register()
{
    var config = new HttpConfiguration();
    config.MapHttpAttributeRoutes();

    config.Filters.Add(new HostAuthenticationAttribute("bearer")); //added this
    config.Filters.Add(new AuthorizeAttribute());
    config.EnableCors(new EnableCorsAttribute("*", "*", "*", "*"));
    return config;
}

Answer 2

另一個可能對我有用的解決方案是不使用HostAuthenticationAttribute，而是將OWIN過濾器設置為Active過濾器，如下所示：

var bearerOptions = new OAuthBearerAuthenticationOptions
{
    AccessTokenFormat = new JwtFormat(validationParameters),
    AuthenticationMode = AuthenticationMode.Active,
};
