在OpenIdDict中使用客户端凭据时，指定的令牌无效是无效的

问题描述

使用Asp.Net Core 5和OpenIdDict，我可以配置授权代码和客户端凭据：

services.AddOpenIddict()
  
  .AddCore(x => {
    x.UseEntityFrameworkCore().UseDbContext<Context>().ReplaceDefaultEntities<Application,Authorization,Scope,Token,Int32>();
  })

  .AddServer(x => {

    x.SetAuthorizationEndpointUris("/connect/authorize")
     .SetlogoutEndpointUris("/connect/logout")
     .SetTokenEndpointUris("/connect/token")
     .SetUserinfoEndpointUris("/connect/userinfo")
     .SetIntrospectionEndpointUris("/.well-kNown/openid-configuration");

    x.RegisterScopes(OpenIddictConstants.Scopes.Profile,OpenIddictConstants.Scopes.Email,OpenIddictConstants.Scopes.OfflineAccess);

    x.AllowAuthorizationCodeFlow()
     .AllowRefreshTokenFlow()
     .AllowClientCredentialsFlow();

    x.AddDevelopmentEncryptionCertificate().AddDevelopmentSigningCertificate();

    x.UseAspNetCore()
     .EnableAuthorizationEndpointPassthrough()
     .EnablelogoutEndpointPassthrough()
     .EnabletokenEndpointPassthrough()
     .EnableuserinfoEndpointPassthrough()
     .EnableStatusCodePagesIntegration();
    })

  .AddValidation(x => {
    x.UseLocalServer();
    x.UseAspNetCore();
  });

在API上，我有：

 services.AddOpenIddict()
  .AddValidation(x => {
    x.SetIssuer("https://localhost:5000");
      x.AddAudiences("api");
      x.UseIntrospection().SetClientId("api").SetClientSecret("SecretAPI");
      x.UseSystemNetHttp();
      x.UseAspNetCore();
    });

然后我有了客户端和API应用程序：

  OpenIddictApplicationDescriptor mvc = new OpenIddictApplicationDescriptor {
    ClientId = "mvc",ClientSecret = "SecretMVC",ConsentType = OpenIddictConstants.ConsentTypes.Explicit,Permissions = {
        OpenIddictConstants.Permissions.Endpoints.Token,OpenIddictConstants.Permissions.GrantTypes.ClientCredentials,OpenIddictConstants.Permissions.Prefixes.Scope + "api"
      }
    };

      
  OpenIddictApplicationDescriptor api = new OpenIddictApplicationDescriptor {
    ClientId = "api",ClientSecret = "SecretAPI",Permissions = {
      OpenIddictConstants.Permissions.Endpoints.Introspection
    }
  };

我可以使用Insomnia Rest Client和Client Credentials获得访问令牌。

但是当我使用给定的访问令牌调用API时，会出现以下错误：

Bearer error = "invalid_token",error_description = "The specified token is invalid."

为什么会这样？

更新

在日志中，我有以下内容：

解决方法

您将自省端点配置为与OIDC提供程序配置端点共享相同的地址，这可以防止将自省请求识别为有效的POST请求。

修复SetIntrospectionEndpointUris("/.well-known/openid-configuration")以使用其他地址，它应该可以正常工作。
