c# - (部分)C# HTTP 服务器无法识别 HTTP 请求

Question

在我的 visual studio 13 控制台应用程序中，我在 TCP 套接字上接收到以下字节流(从嵌入式设备接收):

POST /setup HTTP/1.1
Content-Length: 6
Content-Type: application/setup+tlv8

TLV8-data

虽然它看起来是一个有效的 http 请求，但我的以下尝试都没有成功地将它识别为 http 请求:(在常规 HTTP 请求上它们工作得很好)

• .NET HttpListener 类(甚至不通知我已调用任何请求)
• 小道消息(同样的事情，在 POST 或 GET 上给出任何路由)https://github.com/scottoffen/Grapevine
• Alchemy(已调用 OnConnect 方法，但在相应的 UserContext 中我只看到请求路径:/。与此报告的问题类似:https://github.com/Olivine-Labs/Alchemy-Websockets/issues/70

到目前为止，我实际上只对来自 POST 或 GET 的请求路径以及正文中附加的内容(tlv 格式)感兴趣。

我配置有误吗？例如:我需要告诉正确的内容类型？有什么方法可以摆脱编写自己的简单文本解析器的麻烦吗？

小道消息情况下的代码示例:

private void init()
    {
        s = new PairServer();
        s.Host = "172.28.22.78"; 
        s.Port = "52025"; 
        s.Start();
   }

提供以下服务器类:

public class PairServer : RestServer
    {
        [RestRoute(Method = HttpMethod.POST, PathInfo = @"^/setup")]
        [RestRoute(Method = HttpMethod.GET, PathInfo = @"^/setup")]
        public void PairSetup(HttpListenerContext context)
        {
            // will not reach here
        }

        [RestRoute(Method = HttpMethod.POST)]
        public void AnyRoute(HttpListenerContext context)
        {
           // Not even here
        }

Although it seem to be a valid http request

不，那不是有效的 HTTP 请求。有效的 HTTP 请求，如 specification声明，必须包含一个 Host 请求 header :

A client MUST include a Host header field in all HTTP/1.1 request messages . If the requested URI does not include an Internet host name for the service being requested, then the Host header field MUST be given with an empty value. An HTTP/1.1 proxy MUST ensure that any request message it forwards does contain an appropriate Host header field that identifies the service being requested by the proxy. All Internet-based HTTP/1.1 servers MUST respond with a 400 (Bad Request) status code to any HTTP/1.1 request message which lacks a Host header field.

因此请确保您的客户遵循规范:

POST /setup HTTP/1.1
Host: example.com
Content-Length: 6
Content-Type: application/setup+tlv8

TLV8-data
