http2

问题 This may just highlight some misconception of mine, but I was curious: If you had an HTTP/2 server running and wanted to make XHR requests in the browser to the server, would XHR automatically take advantage of the performance optimisations in headers and such that it provides? Or would it ignore that functionality and operate as an HTTP request? If so, are there any things we can do to use the new optimisations in our requests? 回答1: You don't need to do anything. If the server supports HTTP

问题 I'm currently working on a website, which triggers a net::ERR_HTTP2_PROTOCOL_ERROR 200 error on Google Chrome. I'm not sure exactly what can provoke this error, I just noticed it pops out only when accessing the website in HTTPS. I can't be 100% sure it is related, but it looks like it prevents javascript to be executed properly. For instance, the following scenario happens : I'm accessing the website in HTTPS My Twitter feed integrated via https://publish.twitter.com isn't loaded at all I

问题 I have a Python REST service and I want to serve it using HTTP2. My current server setup is nginx -> Gunicorn . In other words, nginx (port 443 and 80 that redirects to port 443) is running as a reverse proxy and forwards requests to Gunicorn (port 8000, no SSL). nginx is running in HTTP2 mode and I can verify that by using chrome and inspecting the 'protocol' column after sending a simple GET to the server. However, Gunicorn reports that the requests it receives are HTTP1.0. Also, I coulnt't

问题 How does HTTP2 solve Head of Line blocking (HOL) issue? This problem is very frequent in http1.1, but I heard HTTP2 has fixed this problem. Could someone explain how exactly HTTP2 fixed the problem? 回答1: HTTP Head of line blocking Head of Line blocking in HTTP terms is often referring to the fact that each browser/client has a limited number of connections to a server and doing a new request over one of those connections has to wait for the ones before to complete before it can fire it off.

问题 Is it possible currently to get node.js HTTP/2 (HTTP 2.0) server? And http 2.0 version of express.js? 回答1: If you are using express@^5 and http2@^3.3.4 , then the correct way to start the server is: const http2 = require('http2'); const express = require('express'); const app = express(); // app.use('/', ..); http2 .raw .createServer(app) .listen(8000, (err) => { if (err) { throw new Error(err); } /* eslint-disable no-console */ console.log('Listening on port: ' + argv.port + '.'); /* eslint

问题 Jetty's HTTP/2 client with server push support has been implemented in Jetty 9.3 RC (Link). However, I have not found any documentation or example code related to this. Could any one provide an example code for example to receive the pushed resource from this site : https://nghttp2.org (public server which has enabled http2 server push) ---UPDATE 1--- I have tried to test this file as sbordet has said. However, after executing this line mvn compile exec:java I ran onto this error [INFO] ---

问题 We have many React Native <Image> components rendering per screen and are witnessing performance issues due to many simultaneous http requests. Opening and closing a connection is expensive, and having too many simultaneous connections can hit limitations that cause timeouts. HTTP/2 features multiplexing, allowing multiple requests and response messages between the client and server to be in flight at the same time over a single connection, instead of multiple connections, which improves page

问题 I am building a webapp and serving it over http2. However when I analyze network in Google Chrome (Version 59.0.3071.115 (Official Build) (64-bit))'s developers tools, it is clear that multiplexing does not work as there are only 6 active connections (like with http1.1) and the rest of connections are queued. Why is this? Or are my expectations not correct? The screenshot (you can see that protocol is http2): Update #1: The backend runs on nginx 1.13; I am using custom modules loader which

问题 I have been searching how to implement Conscrypt SSL provider using conscrypt-openjdk-uber-1.4.1.jar for jdk8 to support ALPN for making a http2(using apache httpclient 5) connection to a server as jdk8 does not support ALPN by default or the other solution is to migrate to jdk9(or higher) which is not feasible for now as our product is heavily dependent on jdk8 I have been searching extensively for some docs or examples to implement but I could not find one. I have tried to insert conscrypt
