Generate Twitch auth tokens

An example how to generate Twitch access tokens with custom scopes. The example requires BlushyFace.Twitch.Authentication and BlushyFace.Common.HTTP to run a local HTTP server.

using System.Collections.Specialized;
using BlushyFace.Common.HTTP;
using BlushyFace.Config;
using BlushyFace.Twitch.API.Auth;
using BlushyFace.Twitch.API.Auth.ResponseObjects;
using Newtonsoft.Json;

namespace BlushyFace.Examples
{
    public static class AuthDemo
    {
        public static Settings Settings = new Settings(); // auto loads settings from settings file.
        public static Server HTTPServer = new BlushyFace.Common.HTTP.Server(new[] { "http://+:8081/" });
        private static TokenResponse _token;
        private static readonly OAuth _auth = new OAuth();

        public static async void Run()
        {
            HTTPServer.OnResponse += HttpServer_OnResponse; // listens to redirect uri events

            // opens a browser or tab when a browser is open to the Twitch auth page.
            // After the user authenticates themselves it redirects with the redirect url with a token / exchange code for further processing.
            OAuth.OpenBrowserImplicit(Settings.ClientId, Settings.RedirectUrl, "channel_read+bits:read+channel:read:subscriptions");
            OAuth.OpenBrowserAuthorization(Settings.ClientId, Settings.RedirectUrl, "channel_read+bits:read+channel:read:subscriptions+moderation:read+user:edit:broadcast");

            // generate, validate, refresh and revoke a token manually
            var clientCredentials = await _auth.GenerateClientCredentialsFlowAsync(Settings.ClientId, Settings.ClientSecret, "channel_read");
            _token = await _auth.GenerateAuthorizationCodeFlowTokenAsync(Settings.ClientId, Settings.ClientSecret, Settings.RedirectUrl, "...", OAuth.GenerateState(), true);

            var validateToken = await _auth.ValidateTokenAsync(_token.AccessToken);
            var refreshToken = await _auth.RefreshTokenAsync(Settings.ClientId, Settings.ClientSecret, _token.RefreshToken);
            var revokeToken = await _auth.RevokeTokenAsync(Settings.ClientId, _token.AccessToken);
        }
        
        // automatically exchange code from authorization flow to a token and show the token data in the browser.
        private static async void HttpServer_OnResponse(object sender, NameValueCollection queryString)
        {
            if (queryString.Get("code") != null)
            {
                _token = await _auth.GenerateAuthorizationCodeFlowTokenAsync(Settings.ClientId, Settings.ClientSecret, Settings.RedirectUrl, queryString.Get("code"), OAuth.GenerateState());

                HTTPServer.WriteResponse($"{JsonConvert.SerializeObject(_token, Formatting.Indented)}");

                // saves the token to a config file. -> Config/Settings.json
                if (_token.AccessToken != null)
                {
                    Settings.SaveSettings(_token);
                }
            }
        }
    }
