来源:Say hello to HTTP/2 for Node.js Core – Node.js Collection – Medium
A few minutes ago I opened the initial pull-request that would provide an implementation of HTTP/2 for Node.js core. While it’s far from being production ready, this marks a key milestone.
Because this is just a pull-request, it’s possible to play around with, but there are a few additional steps.
First, you’ll need to make sure you’re set up for building Node.js locally by following the instructions here: https://github.com/nodejs/nod...
After that, check out the working branch:
$ git clone https://github.com/jasnell/node $ git checkout initial-pr
Then build...
$ ./configure $ make -j8
Warning, building Node.js from scratch takes quite a bit of time. So go grab a quick snack while things get going.
Once complete, you can create a functioning HTTP/2 server in a few lines of code:
const http2 = require("http2"); const server = http2.createServer(); server.on("stream", (stream, requestHeaders) => { stream.respond({ ":status": 200, "content-type": "text/plain" }); stream.write("hello "); stream.end("world"); }); server.listen(8000);
Because the HTTP/2 support is still experimental, in order to run this server, the Node.js instance must be started using the --expose-http2 command line argument:
$ node --expose-http2 h2server.js
Note that the server above uses plain-text TCP connection so the server will not be accessible from Web Browsers, which require using TLS. We can, however, create a simple HTTP/2 client:
const http2 = require("http2"); const client = http2.connect("http://localhost:8000"); const req = client.request({ ":method": "GET", ":path": "/" }); req.on("response", (responseHeaders) => { // do something with the headers }); req.on("data", (chunk) => { // do something with the data }); req.on("end", () => client.destroy());
Setting up a TLS-enabled HTTP/2 server requires just a few more additional steps:
const http2 = require("http2"); const options = { key: getKeySomehow(), cert: getCertSomehow() }; const server = http2.createSecureServer(options); server.on("stream", (stream, requestHeaders) => { stream.respond(); stream.end("secured hello world!"); }); server.listen(43);
Refer to the Node.js tls.createServer() documentation for more information regarding the required key and cert configuration options.
While there are many details that still need to worked through, and likely many issues that need to be fixed… this initial implementation provides enough functionality to get started, including:
Push Stream Support
respondWithFile() and respondWithFD() APIs that allow extremely efficient sending of raw file data that bypasses the Streams API.
TLS and Plain-text connections
Full support for stream multiplexing
HTTP/2 Prioritization and Flow Control
Support for HTTP/2 trailers
HPACK header compression support
A compatibility API layer that operates as close as possible to the existing HTTP/1 API
Development will be ongoing, as will security hardening, performance optimization, and API refinement. The more input we get on this, the better it will become.
Happy Multiplexing to All :-)
