c# – 使用NancyFX自托管的分块压缩响应

我有一个系统应该写入HTTP响应流的行.此系统中的每一行代表某种事件,因此您可以将其视为通知流.我在 Windows 7上使用.NET4使用NancyFX和Nancy自托管(0.23).以下代码功能正常：

using System;
using System.IO;
using System.Threading;
using Nancy;
using Nancy.Hosting.Self;

namespace TestNancy
{
    public class ChunkedResponse : Response
    {
        public ChunkedResponse()
        {
            ContentType = "text/html; charset=utf-8";
            Contents = stream =>
            {
                using (var streamWriter = new StreamWriter(stream))
                {
                    while (true)
                    {
                        streamWriter.WriteLine("Hello");
                        streamWriter.Flush();
                        Thread.Sleep(1000);
                    }
                }
            };
        }
    }

    public class HomeModule : NancyModule
    {
        public HomeModule()
        {
            Get["/"] = args => new ChunkedResponse();
        }
    }

    public class Program
    {
        public static void Main()
        {
            using (var host = new NancyHost(new Uri("http://localhost:1234")))
            {
                host.Start();
                Console.ReadLine();
            }
        }
    }
}

现在我想为流添加压缩以压缩带宽量.出于某种原因,在浏览器中进行测试时,我无法看到任何结果.我已经尝试了很多组合来达到预期的效果,但这就是我现在所拥有的：

using System; using System.IO; using System.IO.Compression; using System.Threading; using Nancy; using Nancy.Hosting.Self;

namespace TestNancy {
    public class ChunkedResponse : Response
    {
        public ChunkedResponse()
        {
            Headers["Content-Encoding"] = "gzip";
            ContentType = "text/html; charset=utf-8";
            Contents = stream =>
            {
                using (var gzip = new GZipStream(stream,CompressionMode.Compress))
                using (var streamWriter = new StreamWriter(gzip))
                {
                    while (true)
                    {
                        streamWriter.WriteLine("Hello");
                        streamWriter.Flush();
                        Thread.Sleep(1000);
                    }
                }
            };
        }
    }

    public class HomeModule : NancyModule
    {
        public HomeModule()
        {
            Get["/"] = args => new ChunkedResponse();
        }
    }

    public class Program
    {
        public static void Main()
        {
            using (var host = new NancyHost(new Uri("http://localhost:1234")))
            {
                host.Start();
                Console.ReadLine();
            }
        }
    } }

我正在寻找帮助,要么告诉我我在HTTP协议上做错了什么(例如我尝试添加HTTP1.1中描述的块长度,这不起作用),或者帮助关于Nancy,它做了我没做过的事情对于.

解决方法

问题似乎是在Gzip框架的实现中,因为它在关闭之前从未写入输出流,

我只是使用SharpZiplib,你的代码似乎对我有用,这是我的修改

public class ChunkedResponse : Response
{
    public ChunkedResponse()
    {
        Headers["Transfer-Encoding"] = "chunked";
        Headers["Content-Encoding"] = "gzip";
        ContentType = "text/html; charset=utf-8";
        Contents = stream =>
        {
            var gzip = new ICSharpCode.SharpZipLib.GZip.GZipOutputStream(stream);
            using (var streamWriter = new StreamWriter(gzip))
            {
                while (true)
                {
                    streamWriter.WriteLine("Hello");
                    gzip.Flush();
                    streamWriter.Flush();
                    Thread.Sleep(1000);
                }
            }

        };
    }
}


public class HomeModule : NancyModule
{
    public HomeModule()
    {
        Get["/"] = args => new ChunkedResponse();
    }
}

public class Program
{
    public static void Main()
    {
        using (var host = new NancyHost(new HostConfiguration{AllowChunkedEncoding = true},new Uri("http://localhost:1234")))
        {

            host.Start();
            Console.ReadLine();
        }
    }
}
