[英]“Message”: “Authorization has been denied for this request.” OWIN middleware
我将基于令牌的身份验证添加到我的OWIN中间件,并可以生成令牌。 但是在使用时,带有Authorize属性的API调用的令牌总是得到“此请求已拒绝授权”。 没有Authorize属性,它工作正常。 这是我的startup.cs和控制器方法。 有什么想法,有什么不对?
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());
}
}
这可能是允许的受众群体的一个问题。 这里
app.UseJwtBearerAuthentication(new JwtBearerAuthenticationOptions
{
...
AllowedAudiences = new[] { "*" },
...
}
您设置允许的受众群体。 令牌aud
要求将针对列表进行检查AllowedAudiences
。 但是,您永远不会向令牌添加任何受众。
在我们的项目中,我使用了基于http://bitoftech.net/2014/10/27/json-web-token-asp-net-web-api-2-jwt-owin-authorization-server中显示的代码的CustomJwtFormat /
将通过调用生成令牌
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
索赔:
来自https://msdn.microsoft.com/en-us/library/dn451037(v=vs.114).aspx :
audience类型:System.String
如果此值不为空,则会添加{aud,'audience'}声明。
在令牌授权中设置aud
声明后,应该可以正常工作。
根据我的理解,你需要添加标题:Authorization:Bearer“token”。 如果您尚未修改授权请求的默认实现,则步骤如下:
在端点注册用户:
/api/Account/Register
复制该令牌并使用类型为[Authorize]过滤器的方法创建对您保护的方法的请求:
Authorization: Bearer "the_token_you_copied_earlier"
毋庸置疑,如果您使用Postman或Fiddler来制作和接收请求,这对您来说可能很容易,因为它向您展示了一切是如何工作的。
