ApricotFramework.Authentication

Both directions of a microservice's authentication from one settings section: JWT bearer validation for the requests it serves, and OAuth 2.0 client credentials tokens for the services it calls — discovered, cached until shortly before they expire, and coalesced so a cold start makes one token request rather than one per caller.

ApricotFramework.Authentication is the zero-dependency core, and works in a console or worker host without ASP.NET Core.

Install

dotnet add package ApricotFramework.Authentication.AspNetCore
dotnet add package ApricotFramework.Authentication.ErrorDefinitions   # to answer with problem+json

Usage

// Inbound validation and the outbound client, from one section.
builder.Services.AddJwtBearerAuthentication(builder.Configuration);
builder.Services.AddAuthorization();
builder.Services.AddAuthenticationErrorDefinitions();

{
  "Authentication": {
    "Authority": "https://idp.example.com",
    "ValidAudiences": [ "orders-api" ],
    "Client": {
      // The secret comes from the environment, as Authentication__Client__ClientSecret.
      "ClientId": "orders-service",
      "Scopes": [ "billing.read" ]
    }
  }
}

[HttpGet("{id}")]
[BearerAuthorize]
public async Task<Order> Get(string id, CancellationToken cancellationToken)
{
    // Works for a person and for a service alike: Subject is null for a machine token, because a
    // client credentials grant has no resource owner to name.
    var caller = this.HttpContext.GetPrincipal();

    return await this.authenticator.DoAuthenticatedAsync(
        (token, ct) => this.billing.GetAsync(id, token, ct),
        cancellationToken: cancellationToken);
}

Note. A token this service could not obtain for an onward call never answers 401 or 403. The caller presented a good credential; it is this service that could not present one of its own, so it answers 503 when waiting may help and 500 when it will not.

Package	Downloads
ApricotFramework.Authentication.AspNetCore ASP.NET Core integration for ApricotFramework.Authentication: JWT bearer validation configured from one settings section, a service-to-service client whose credentials come from the same section, and startup validation that rejects a resource server which could never accept a token.	105
ApricotFramework.Grpc.Client.Authentication Presents this service's own access token on outbound gRPC calls, obtained through ApricotFramework.Authentication, and reports a failure to obtain one as a fault of this service rather than of whoever called it.	102
