A DelegatingHandler implementation that abstracts away some of the authentication handshake logic like requesting the jwt token caching, and refreshing it.
public void ConfigureServices(IServiceCollection services)
{
var settings = new Settings(clientId: "id",
clientSecret: "secret",
scope: "role:app",
endpoint: new Uri("https://authority.local"),
expireMargin: TimeSpan.FromMinutes(10));
services.AddHttpClient("authenticatedHttpClient").WithOAuth(settings);
}To facilitate configuration from IConfiguration you can use the SettingsDto to create the required settings directly from IConfiguration
Add the required settings to your appsettings.json
{
"OAuthSettings": {
"ClientId": "client_id",
"ClientSecret": "client_secret",
"Scopes": ["api1", "api2"],
"TokenEndpoint": "https://localhost:5001/connect/token"
}
}Initialize the client with the correct settings (or any other ConfigurationSource)
var settings = hostBuilder.Configuration.GetRequiredSection("OAuthSettings").Get<SettingsDto>();
hostBuilder.Services.AddHttpClient("authenticatedHttpClient").WithOAuth(settings);
