标签: node.js http express http2

目前是否可以获得node.js HTTP / 2(HTTP 2.0)服务器?和http 2.0版本的express.js?

var express = require('express');
var app = express();

app.get('/', function (req, res) {
  res.send('hello, http2!');
});

var options = {
  key: fs.readFileSync('./example/localhost.key'),
  cert: fs.readFileSync('./example/localhost.crt')
};

require('http2').createServer(options, app).listen(8080);

如果您使用express@^5http2@^3.3.4,则启动服务器的正确方法是:

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-enable no-console */
    });

注意https2.rawThis is required if you want to accept TCP connections.

请注意,在撰写本文时(2016 05 06),none of the major browsers support HTTP2 over TCP

如果要接受TCP和TLS连接,则需要使用默认的createServer方法启动服务器:

const http2 = require('http2');
const express = require('express');
const fs = require('fs');


const app = express();

// app.use('/', ..);

http2
    .createServer({
        key: fs.readFileSync('./localhost.key'),
        cert: fs.readFileSync('./localhost.crt')
    }, app)
    .listen(8000, (err) => {
        if (err) {
            throw new Error(err);
        }

        /* eslint-disable no-console */
        console.log('Listening on port: ' + argv.port + '.');
        /* eslint-enable no-console */
    });

请注意,在撰写本文时,我确实设法让expresshttp2工作(请参阅https://github.com/molnarg/node-http2/issues/100#issuecomment-217417055)。但是,我设法使用spdy包来使http2(和SPDY)工作。

const spdy = require('spdy');
const express = require('express');
const path = require('path');
const fs = require('fs'); 

const app = express();

app.get('/', (req, res) => {
    res.json({foo: 'test'});
});

spdy
    .createServer({
        key: fs.readFileSync(path.resolve(__dirname, './localhost.key')),
        cert: fs.readFileSync(path.resolve(__dirname, './localhost.crt'))
    }, app)
    .listen(8000, (err) => {
        if (err) {
            throw new Error(err);
        }

        /* eslint-disable no-console */
        console.log('Listening on port: ' + argv.port + '.');
        /* eslint-enable no-console */
    });

自 2018 年以来,express 5.0 有一个公开的 pr,https://github.com/expressjs/express/pull/3730。在合并之前,它不会开箱即用。

我以包的形式创建了解决方案,https://www.npmjs.com/package/http2-express-bridge

const express = require('express')
const http2Express = require('http2-express-bridge')
const http2 = require('http2')
const { readFileSync } = require('fs')

// Use the wrapper function that returns the application
const app = http2Express(express)

const options = {
    key: readFileSync('<Certificate Key>'),
    cert: readFileSync('<Certificate file>'),
    allowHTTP1: true
};


app.get('/', function (req, res) {
  res.send('Hello World')
})

const server = http2.createSecureServer(options, app)

server.listen(3000, () => {
        console.log(`listening on port 3000`)
})

这是有效的,当它收到一个 Http/1.1 请求时它会回退到 Http/1.1。

为了便于服务器推送,我还包含了“res.push”方法。该包适用于 ESModules 和 Typescript。

这个问题至今仍然存在(一年之后),所以我决定制定一个解决方法,使express和http2包很好地协同工作。 我已经创建了一个npm包,它正是这样做的:https://www.npmjs.com/package/express-http2-workaround

通过NPM安装:npm install express-http2-workaround --save

// Require Modules
var fs = require('fs');
var express = require('express');
var http = require('http');
var http2 = require('http2');

// Create Express Application
var app = express();

// Make HTTP2 work with Express (this must be before any other middleware)
require('express-http2-workaround')({ express:express, http2:http2, app:app });

// Setup HTTP/1.x Server
var httpServer = http.Server(app);
httpServer.listen(80,function(){
  console.log("Express HTTP/1 server started");
});

// Setup HTTP/2 Server
var httpsOptions = {
    'key' : fs.readFileSync(__dirname + '/keys/ssl.key'),
    'cert' : fs.readFileSync(__dirname + '/keys/ssl.crt'),
    'ca' : fs.readFileSync(__dirname + '/keys/ssl.crt')
};
var http2Server = http2.createServer(httpsOptions,app);
http2Server.listen(443,function(){
  console.log("Express HTTP/2 server started");
});

// Serve some content
app.get('/', function(req,res){
    res.send('Hello World! Via HTTP '+req.httpVersion);
});

上面的代码是一个工作快速应用程序,它使用nodejs http模块(用于HTTP / 1.x)和http2模块(用于HTTP / 2)。

如自述文件中所述,这将创建新的express请求和响应对象,并将其原型设置为http2的IncomingMessage和ServerResponse对象。默认情况下,它是内置nodejs http IncomingMessage和ServerResponse对象。

我希望这会有所帮助:)
