Add authentication header after login

[mhmmdsmdi]

I want to get authentication token by calling IAuthentication.Login(username,password)
and then use the result (Brearer Token) in other interfaces like user

I use this code for my DI

services.AddHttpClient("ScadaApiClient") .ConfigureHttpClient(x => x.BaseAddress = baseAddress) .UseWithRestEaseClient<IAuthenticationApi>() .UseWithRestEaseClient<IUserApi>();

You've basically got two options:

1. Add the Authentication header as a property on IUserApi. In this case, you'll need to assign that property for every instance of IUserApi which is created. There's nothing built-in to let you do this, so you'll have to register IUserApi with the IoC container yourself (without using UseWithRestEaseClient), and add the necessary code to assign to that Authentication header.
2. Add the Authentication header using a custom HttpMessageHandler. You can then register that, using e.g. .AddHttpClient("...").ConfigurePrimaryHttpMessageHandler(...).UseWithRestEaseClient<IUserApi>().
