Quickstart - Protecting an API using Client Credentials -> Adding an API not working on MacOS

[menjoo]

Hi,

I followed along the quickstart and came to this point: Protecting an API using Client Credentials -> Adding an API

I do the following steps from within VS for mac:

1. Solution -> Add new project
2. Asp.Net Core WebAPI (target framework is set to .NETCoreApp 1.1)
3. Add controller like in the quickstart example:

   [Route("identity")]
   [Authorize]
   public class IdentityController : ControllerBase
   {
   [HttpGet]
   public IActionResult Get()
   {
       return new JsonResult(from c in User.Claims select new { c.Type, c.Value });
   }
   }

4. Add NuGet package IdentityServer4.AccessTokenValidation

5. And make Startup.cs configure method like this:

   public void Configure(IApplicationBuilder app, ILoggerFactory loggerFactory)
   {
   loggerFactory.AddConsole(Configuration.GetSection("Logging"));
   loggerFactory.AddDebug();
   
   app.UseIdentityServerAuthentication(new IdentityServerAuthenticationOptions
   {
       Authority = "http://localhost:5000",
       RequireHttpsMetadata = false,
   
       ApiName = "api1"
   });
   
   app.UseMvc();
   }

6. And then run it
7. I get this error

   Unhandled Exception: System.TypeInitializationException: The type initializer for 'System.Net.Http.CurlHandler' threw an exception. ---> System.TypeInitializationException: The type initializer for 'Http' threw an exception. ---> System.TypeInitializationException: The type initializer for 'HttpInitializer' threw an exception. ---> System.TypeInitializationException: The type initializer for 'CryptoInitializer' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'System.Security.Cryptography.Native.OpenSsl': The specified module could not be found.

Edit:

Found the problem.

App seemed to work in docker, so it had to be some environment thingie. After trying some things i found out that i had to do this:

mkdir -p /usr/local/lib ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/ ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/

after that it works.
