http2

问题 I've set up a fresh hosting project (not using any custom domain at the moment) and split up some of my js files expecting them to be served via http2 (as described in firebase blog posts it should be enabled by default?)

问题 Is there a way to force PHP to make a HTTP2 connection to another server just to see if that server supports it? I've tried: $options = stream_context_create(array( 'http' => array( 'method' => 'GET', 'timeout' => 5, 'protocol_version' => 1.1 ) )); $res = file_get_contents($url, false, $options); var_dump($http_response_header); And tried: $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_NOBODY, 1); curl_setopt($ch, CURLOPT

问题 I can't figure out how to covert the following sequential code to a multi-threaded properly. I have done my best to avoid any shared resource and complete thread independence. This is the single-threaded code package com.net; import jdk.incubator.http.HttpClient; import jdk.incubator.http.HttpRequest; import jdk.incubator.http.HttpResponse; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import java.io.IOException; import java.net.URI; import java.net.URISyntaxException; public class

问题 I have a C program of socket which has to use http2 protocol. It is returning Bad Request - HTTP Error 400. The request is badly formed. Initially, I sent a request like the following through curl 7.64: curl -v -http2 -i https://mywebsite.xyz and i got the following output: * Expire in 0 ms for 6 (transfer 0x55cc25ec95c0) * Expire in 1 ms for 1 (transfer 0x55cc25ec95c0) * Expire in 0 ms for 1 (transfer 0x55cc25ec95c0) * Expire in 1 ms for 1 (transfer 0x55cc25ec95c0) * Expire in 0 ms for 1

问题 I just found out that Android's recommended http client HttpUrlConnection doesn't support HTTP/2. Is there a specific reason not to use HTTP/2 on Android? 回答1: You can use OkHttp if you want to take advantage of HTTP/2: https://github.com/square/okhttp It's superior to HttpUrlConnection anyway. If you're doing anything at all complicated, like getting complex JSON responses from a web API, I'd recommend Retrofit: https://square.github.io/retrofit/ 来源： https://stackoverflow.com/questions

问题 On my webserver I'm trying to get H2 (http2) to work. Installed Apache 2.4.20 via the "ondrej" repository. I tested on a Debian 8 and Ubuntu 14.04 server, but I keep running into the same problems. I have OpenSSL 1.0.2 and SSL vhosts running. The strange thing is that the upgrade headers (Connection: upgrade and Upgrade: h2) are sent. When I do some external server testing I get the responses that h2 is running properly with ALPN support. But the problem is the browsers I tested on (Chrome

问题 This question already has answers here : Java 9 no class definition exception (3 answers) Closed last year . Here is the code snippet that I use: HttpClient client = HttpClient.newHttpClient(); HttpRequest request = HttpRequest.newBuilder(URI.create("https://www.google.com")).GET().build(); HttpResponse.BodyHandler responseBodyHandler = HttpResponse.BodyHandler.asString(); HttpResponse response = client.send(request, responseBodyHandler); System.out.println("Status code = " + response

问题 The new HTTP/2 protocol comes with some promising features. Some of them: Multiplexing - a single TCP connection can be used to make multiple HTTP/2 requests and receive multiple responses (to a single origin) HTTP/2 Server Push - sending server responses to the client without receiving requests, i.e. initiated by the server Bidirectional connection - HTTP/2 spec - Streams and Multiplexing: A "stream" is an independent, bidirectional sequence of frames exchanged between the client and server
