问题描述
我在OWIN中间件中添加了基于令牌的身份验证，并且可以生成令牌.但是在使用时，带有Authorize属性的API调用的令牌始终显示为该请求的授权已被拒绝".尽管没有Authorize属性，它也可以正常工作.这是我的startup.cs和控制器方法.有什么想法，怎么了?
I added Token based authentication to my OWIN middleware and can generate the token. But while using, the token for an API call with Authorize attribute I always get "Authorization has been denied for this request." It works fine though without Authorize attribute. Here is my startup.cs and controller method. Any thoughts , what is wrong?
startup.cs
startup.cs
public void Configuration(IAppBuilder app)
{
var issuer = ConfigurationManager.AppSettings["issuer"];
var secret = TextEncodings.Base64Url.Decode(ConfigurationManager.AppSettings["secret"]);
app.UseOAuthAuthorizationServer(new OAuthAuthorizationServerOptions
{
AuthenticationType = DefaultAuthenticationTypes.ExternalBearer,
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/token"),
AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(30),
Provider = new SimpleAuthProvider(),
AccessTokenFormat = new JwtFormat(issuer)
});
app.UseJwtBearerAuthentication(new JwtBearerAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ExternalBearer,
AuthenticationMode = AuthenticationMode.Active,
AllowedAudiences = new[] { "*" },
IssuerSecurityTokenProviders = new IIssuerSecurityTokenProvider[]
{
new SymmetricKeyIssuerSecurityTokenProvider(issuer, secret)
}
});
container = BuildDI();
var config = new HttpConfiguration();
config.Formatters.XmlFormatter.UseXmlSerializer = true;
config.MapHttpAttributeRoutes();
config.SuppressDefaultHostAuthentication();
config.Filters.Add(new HostAuthenticationFilter(DefaultAuthenticationTypes.ExternalBearer));
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
app.UseCors(CorsOptions.AllowAll);
app.UseSerilogRequestContext("RequestId");
app.UseAutofacMiddleware(container);
app.UseAutofacWebApi(config);
app.UseWebApi(config);
RegisterShutdownCallback(app, container);
}
public class SimpleAuthProvider: OAuthAuthorizationServerProvider
{
public override Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
if (context.UserName != context.Password)
{
context.SetError("invalid_grant", "The user name or password is incorrect");
context.Rejected();
return Task.FromResult<object>(null);
}
var ticket = new AuthenticationTicket(SetClaimsIdentity(context), new AuthenticationProperties());
context.Validated(ticket);
return Task.FromResult<object>(null);
}
public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
{
context.Validated();
return Task.FromResult<object>(null);
}
private static ClaimsIdentity SetClaimsIdentity(OAuthGrantResourceOwnerCredentialsContext context)
{
var identity = new ClaimsIdentity(DefaultAuthenticationTypes.ExternalBearer);
identity.AddClaim(new Claim(ClaimTypes.Name, context.UserName));
return identity;
}
}
API控制器方法:
[HttpGet]
[Route("sampleroute")]
[Authorize]
public async Task<HttpResponseMessage> GetSamples(string search)
{
try
{
HttpResponseMessage response;
using (HttpClient client = new HttpClient(Common.CreateHttpClientHandler()))
{
response = await client.GetAsync("test url");
}
var result = response.Content.ReadAsStringAsync().Result;
Samples[] sampleArray = JsonConvert.DeserializeObject<Samples[]>(result);
var filteredSamples = sampleArray .ToList().Where(y => y.NY_SampleName.ToUpper().Contains(search.ToUpper())).Select(n=>n);
log.Information("<==========Ended==========>");
return Request.CreateResponse(HttpStatusCode.OK,filteredSamples);
}
catch (Exception ex)
{
log.Error($"Error occured while pulling the Samples: {ex.ToString()}");
return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, ex.ToString());
}
}
推荐答案
允许的受众群体可能存在问题.在这里
It's probably a problem with the allowed audiences.Here
app.UseJwtBearerAuthentication(new JwtBearerAuthenticationOptions
{
...
AllowedAudiences = new[] { "*" },
...
}
您设置了允许的受众.令牌aud声明将根据AllowedAudiences的列表进行检查.但是，您永远不会在令牌中添加任何受众群体.
you set the allowed audiences. The tokens audclaim will be checked against the list of AllowedAudiences. But you never add any audience to the token.
在我们的项目中，我根据 http://bitoftech.net/2014/10/27/json-web-token-asp-net-web-api-2-jwt-owin -authorization-server/
In our project I used a CustomJwtFormat based on the code shown in http://bitoftech.net/2014/10/27/json-web-token-asp-net-web-api-2-jwt-owin-authorization-server/
将通过调用
var token = new JwtSecurityToken(_issuer, audienceId, data.Identity.Claims, issued.Value.UtcDateTime, expires.Value.UtcDateTime, signingKey);
第二个参数负责JWT中的aud声明:
the second parameter is responsible for the aud claim in the JWT:
来自 https://msdn.microsoft .com/en-us/library/dn451037(v = vs.114).aspx :
如果该值不为null，则会添加{aud，'audience'}声明.
If this value is not null, a { aud, 'audience' } claim will be added.
在令牌授权中设置aud声明后，应该可以正常工作.
After setting the aud claim in the token authorization should work fine.
