Getting access tokens from IdentityServer via a HttpMessageHandler

This repo contains the source code for the blog post where I explained how to encapsulate the action of getting access tokens from IdentityServer (or any token service) by using the HttpClientFactory and HttpMessageHandler.

What's in this repo

The sample is composed of 3 ASP.NET services:

1. IdentityServer
2. Consumer API
3. Protected API

How they talk to each other is explained in the blog post. In a nutshell, the Consumer API exposes endpoints that returns data obtained from the Protected API. The Consumer API obtains access tokens from IdentityServer and uses it to retrieves "confidential" information from the Protected API.

Running the sample

• Run docker-compose up from the root to start all apps.
• Send a request to the Consumer API on: http://localhost:5006/api/consumer/version3
• Optionally, you can try version1 and version2. The results are the same, but the code is different. See blog post for more info.

Requirements

• Docker/Compose
• .NET 6 SDK (if you want to build/debug locally)
