如何通过TLS使用HTTP/2发送HTTP请求？（Java 11 HttpClient）

Question

private void obtainResponse(Socket socket, IHttpRequest req, String uri) {

        HttpClient client = null;
        if (req.isSSL()) {
            SSLContext sslContext = ((SecureConnectionHandler)connHandler).createSSLContext( req.getHost() );

                    .connectTimeout(Duration.ofSeconds(30))
                    .priority(1)
                    .version(HttpClient.Version.HTTP_2)
                    .followRedirects(Redirect.NORMAL)
                    .sslContext( sslContext )
                    .build();
        }

你在我的代码里看到什么奇怪的吗？我知道HTTP/2压缩帧中的标头，但我假定是HTTPClient在内部完成的...

如果您需要更多信息，请告诉我：）

提前谢谢你。
