Login method in Angular

Answer 1

I used the following solution to allow my custom header in Owin self-hosted web api

using Owin;
using Microsoft.Owin.Cors;
using System.Threading.Tasks;
using System.Web.Cors;

namespace App.Web.App_Start
{
    public static class CorsConfig
    {
        public static void Configure(IAppBuilder app)
        {
            var allowedOrigins = "comma,separated,list,of,origins";
            var corsPolicy = new CorsPolicy
            {
                AllowAnyHeader = true,
                AllowAnyMethod = true,
                AllowAnyOrigin = false,
                SupportsCredentials = true
            };

            corsPolicy.ExposedHeaders.Add("Custom-Header");

            foreach (string origin in allowedOrigins.Split(','))
                corsPolicy.Origins.Add(origin);

            app.UseCors(new CorsOptions
            {
                PolicyProvider = new CorsPolicyProvider
                {
                    PolicyResolver = context => Task.FromResult(corsPolicy)
                }
            });
        }

    }

}

I call the method like this CorsConfig.Configure(app); // app is Owin.IAppBuilder
