使用Asp.Net Core WebAPI进行授权

Question

不可否认,这是建立Asp.Net Core web api项目的第一步.一个要求是支持OAuth2.Api和Identity服务器是两个独立的项目,都是从Asp.Net核心空模板开始的.

身份服务器已启动并正在运行,并且正在通过资源所有者流提供令牌.获取令牌很好,范围和相关的access_token详细信息似乎是正确的.

当我向我的资源端点发出get请求时,我首先得到以下信息......

info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
      Request starting HTTP/1.1 GET http://localhost:12886/v1/mystuff
info: Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerMiddleware[2]
      Successfully validated the token.
info: Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerMiddleware[3]
      HttpContext.User merged via AutomaticAuthentication from authenticationScheme: Bearer.
info: Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerMiddleware[8]
      AuthenticationScheme: Bearer was successfully authenticated.
info: IdentityModel.AspNetCore.ScopeValidation.ScopeValidationMiddleware[0]
      Scopes found on current principal: scope: stuffdetails, scope: stuffmover
info: Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerMiddleware[8]
      AuthenticationScheme: Bearer was successfully authenticated.
info: Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[1]
      Authorization was successful for user: 939d72dd-654c-447f-a65d-d0426b1eca59.

所以,我可以告诉中间件正在验证我的令牌,读取范围以及验证令牌. 但是,在最初的成功之后,我立即获得了授权失败.

info: Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[2]
      Authorization failed for user: 939d72dd-654c-447f-a65d-d0426b1eca59.
info: Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker[1]
      Authorization failed for the request at filter 'Microsoft.AspNetCore.Mvc.Authorization.AuthorizeFilter'.
info: Microsoft.AspNetCore.Mvc.ChallengeResult[1]
      Executing ChallengeResult with authentication schemes ().
info: Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerMiddleware[13]
      AuthenticationScheme: Bearer was forbidden.
info: Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker[2]
      Executed action TestApi.StuffController.GetStuff (TestApi) in 32.4439ms
info: Microsoft.AspNetCore.Hosting.Internal.WebHost[2]
      Request finished in 1207.1769ms 403

以下是我认为启动时的相关内容.

ConfigureServices ...

services.AddMvcCore()
        .AddAuthorization(opts =>
            {
                opts.AddPolicy("stuffdetails",
                    policy => policy.RequireClaim("stuffdetails"));
            }
        )
        .AddJsonFormatters();

services.AddOptions();

配置 - 请注意,我知道我的configOptions是正确的,因为初始令牌质询是成功的.

var authServerOptions = new IdentityServerAuthenticationOptions
{
    Authority =  configOptions.Value.AuthServerSettings.AuthServerURI,
    RequireHttpsMetadata = configOptions.Value.AuthServerSettings.RequiresHttpsMetaData,
    ApiName = configOptions.Value.AuthServerSettings.ApiName,
    AllowedScopes = configOptions.Value.AuthServerSettings.AllowedScopes,
    SupportedTokens = IdentityServer4.AccessTokenValidation.SupportedTokens.Jwt,
    AuthenticationScheme = "Bearer",
    SaveToken = true,
    ValidateScope = true
};

app.UseIdentityServerAuthentication(authServerOptions);
app.UseMvc();

东西控制器

[Route("v1/[controller]")]
[Authorize(ActiveAuthenticationSchemes = "Bearer")]
public class StuffController : Controller
{
    [HttpGet]
    [Authorize(Policy = "stuffdetails")]
    public JsonResult GetStuff()
    {
        return new JsonResult(new
        {
            Message = "You've got stuff.."
        });
    }
}

如果我从GetStuff方法中删除Authorize属性,一切都很好,因为如日志所示,持有者令牌被授权.

问题:

1. 授权是否因为我的政策不正确而失败,如果是这样,应如何设置？
2. 如果我想验证令牌包含正确的声明并获得授权,那么使用策略是否正确？
3. 我是否在尝试使用UseIdentityServerAuthentication而不是UseJwtBearerAuthentication时犯了错误？

任何帮助是极大的赞赏..

授权失败是否是因为我的策略不正确，如果是，应该如何设置？

您所得到的看起来是正确的，但是您可以通过删除授权属性的“策略”部分来轻松验证：如果它现在有效，那么问题与您的策略有关，如果它仍然失败，那么这是一个更广泛的问题不仅仅是你的政策。IProfileService我假设您正在使用自己的?实现将“stuffdetails”声明添加到您的 access_token 中

如果我想验证令牌包含正确的声明并且已获得授权，那么使用我所拥有的策略是否正确？

是的，这似乎是进行自定义授权的 aspnet 核心方式。

我尝试使用 UseIdentityServerAuthentication 而不是 UseJwtBearerAuthentication 是否犯了错误？

我正在使用UseIdentityServerAuthentication随ResourceOwnerPassword流。我很想知道该UseJwtBearerAuthentication方法是否是首选或提供其他功能。
