Welche Website unterstützt http/2 auf Port 80 ohne SSL?

Question

Ich möchte einen wireshark auf http/2 für Port 80

1. be able to test out an http/2 client 
2. follow a wireshark trace to understand the protocol better 

Gibt es eine Website ausführen, die http/2 auf 80 Port unterstützt? Wenn ich zu Google gehe, ändert es mich immer zu https.

Dank, Dean

Das Jetty Projekt implementiert eine HTTP/2-Server, der mit sowohl verschlüsselten HTTP/2 und Klartext-HTTP/2 arbeiten kann.

Sie können lokal einen Jetty h2c Server mit Unterstützung für direkte HTTP/2-Kommunikation sowie Unterstützung für HTTP/1.1-Aktualisierung auf HTTP/2 einrichten.

empfehle ich Sie keinen öffentlichen Server mit Ihren Experimenten bombardieren :)

Dies ist der Server-Code:

public class H2C 
{ 
    public static void main(String[] args) throws Exception 
    { 
     Server server = new Server(); 

     HttpConfiguration config = new HttpConfiguration(); 
     HttpConnectionFactory h1 = new HttpConnectionFactory(config); 
     HTTP2CServerConnectionFactory h2 = new HTTP2CServerConnectionFactory(config); 
     ServerConnector connector = new ServerConnector(server, h1, h2); 
     connector.setPort(8080); 
     server.addConnector(connector); 

     server.setHandler(new AbstractHandler() 
     { 
      @Override 
      protected void doHandle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException 
      { 
       baseRequest.setHandled(true); 
       // Your code here. 
      } 
     }); 

     server.start(); 
    } 
} 

Sie einen HTTP/2-Client verwendet, kann der Server zu testen, wie als nghttp, und beobachten Sie den Verkehr über Wireshark.

Testing Klartext HTTP/2 über Upgrade (die -u Flag verwenden, ist die -v Flagge für Ausführlichkeit):

$ nghttp -uv http://localhost:8080/

Oder testen Klartext HTTP/2 direkt:

$ nghttp -v http://localhost:8080/
