哪个网站在没有 SSL 的情况下支持 http/2 端口 80？

Question

我想运行 http/2 上的 wireshark 端口 80 到

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

有没有支持http/280端口的网站？当我转到 google 时，它总是将我更改为 https。

谢谢，院长

Jetty 项目实现了一个 HTTP/2 服务器，可以使用加密 HTTP/2 和明文 HTTP/2。

您可以在本地轻松设置 Jetty h2c 服务器，支持直接 HTTP/2 通信以及支持 HTTP/1.1 升级到 HTTP/2.

我建议您不要用实验轰炸 public 服务器 :)

这是服务器代码：

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();
    }
}

您可以使用 HTTP/2 客户端来测试服务器，例如 nghttp，并通过 Wireshark 观察流量。

通过升级测试明文 HTTP/2（使用 -u 标志，-v 标志用于冗长）：

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