cuipod

Simple yet flexible framework for Gemini protocol servers written in C# (.NET 5.0)

Example

For testing purposes you can generate certificate with this command

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privatekey.key -out certificate.crt

using System;
using System.Security.Cryptography.X509Certificates;
using Microsoft.Extensions.Logging;
using Cuipod;

namespace CuipodExample
{
    class Server
    {
        static int Main(string[] args)
        {
            X509Certificate2 cert = CertificateUtils.LoadCertificate(
                "<dir_with_cert>/certificate.crt",  // Path to certificate
                "<dir_with_cert>/privatekey.key"    // Path to private Pkcs8 RSA key
            );

            using ILoggerFactory loggerFactory = LoggerFactory.Create(builder =>
                builder
                .AddSimpleConsole(options =>
                {

                    options.TimestampFormat = "hh:mm:ss ";
                })
                .SetMinimumLevel(LogLevel.Debug)
            );
            ILogger<App> logger = loggerFactory.CreateLogger<App>();

                response.RenderPlainTextLine("# woah much dynamic content!");
            });

            // Optional but nice. In case it is specified and client will do a bad route 
            // request we will respond with Success status and render result from this lambda
            app.OnBadRequest((request, response, logger) => {
                response.RenderPlainTextLine("# Ohh No!!! Request is bad :(");
            });

            app.Run();

            return 0;
