Question

鉴于具有实验性HTTP2支持的Node.js的最新版本：

$ node -v
v9.2.0

HTTP2服务器：

var options = {
  key: getKey(),
  cert: getCert(),
  allowHTTP1: true
}

var server = http2.createSecureServer(options)
server.on('stream', onstream)
server.on('error', onerror)
server.on('connect', onconnect)
server.on('socketError', onsocketerror)
server.on('frameError', onframeerror)
server.on('remoteSettings', onremotesettings)
server.listen(8443)

function onconnect() {
  console.log('connect')
}

function onremotesettings(settings) {
  console.log('remote settings', settings)
}

function onframeerror(error) {
  console.log('frame error', error)
}

function onsocketerror(error) {
  console.log('socket error', error)
}

function onerror(error) {
  console.log(error)
}

function onstream(stream, headers) {
  console.log('stream')
}

并向它提出了一个请求：

var https = require('https')

var options = {
  method: 'GET',
  hostname: 'localhost',
  port: '8443',
  path: '/',
  protocol: 'https:',
  rejectUnauthorized: false,
  agent: false
}

var req = https.request(options, function(res){
  var body = ''
  res.setEncoding('utf8')
  res.on('data', function(data){
    body += data;
  });
  res.on('end', function(){
    callback(null, body)
  })
})

req.end()

它只是挂起并最终说：

Error: socket hang up
at createHangUpError (_http_client.js:330:15)
    at TLSSocket.socketOnEnd (_http_client.js:423:23)
    at TLSSocket.emit (events.js:164:20)
    at endReadableNT (_stream_readable.js:1054:12)
    at _combinedTickCallback (internal/process/next_tick.js:138:11)
    at process._tickCallback (internal/process/next_tick.js:180:9)

如果设置了rejectUnauthorized: true，则会出错：

Error: self signed certificate
    at TLSSocket.onConnectSecure (_tls_wrap.js:1036:34)
    at TLSSocket.emit (events.js:159:13)
    at TLSSocket._finishInit (_tls_wrap.js:637:8)

不确定出现了什么问题以及为什么它不会到达记录stream。

如果我进入浏览器并访问https://localhost:8443，然后点击警告消息，它实际上会记录stream并成功发出请求。但是还没能得到节点来发出请求。

我想将此视为HTTP1服务器，因此不要使用HTTP2客户端发出请求。但尝试使用同样的东西。

HTTP / 1不与HTTP / 2共享相同的请求语义，因此需要在HTTP / 2服务器中检测和处理HTTP / 1客户端。要同时支持，您需要使用HTTP2 Compatibility API。

＆＃34;挂起＆＃34;当HTTP1客户端连接到设置了allowHTTP1: true但未处理HTTP / 1请求的HTTP / 2服务器时发生。

示例基于Node documentation example code。

HTTP / 1和/ 2混合服务器

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

var options = {
  key: fs.readFileSync('server-key.pem'), 
  cert: fs.readFileSync('server-crt.pem'), 
  //ca: fs.readFileSync('ca-crt.pem'), 
  allowHTTP1: true,
}

var server = http2.createSecureServer(options, (req, res) => {
  // detects if it is a HTTPS request or HTTP/2
  const { socket: { alpnProtocol } } = (req.httpVersion === '2.0')
    ? req.stream.session 
    : req

  res.writeHead(200, { 'content-type': 'application/json' })
  res.end(JSON.stringify({
    alpnProtocol,
    httpVersion: req.httpVersion
  }))
})

server.listen(8443)

HTTP / 2客户端

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

const client = http2.connect('https://localhost:8443', {
    ca: fs.readFileSync('ca-crt.pem'),
    rejectUnauthorized: true,
})
client.on('socketError', (err) => console.error(err))
client.on('error', (err) => console.error(err))

const req = client.request({ ':path': '/' })

req.on('response', (headers, flags) => {
  for (const name in headers) {
    console.log('Header: "%s" "%s"', name, headers[name])
  }
})

req.setEncoding('utf8')
let data = ''
req.on('data', chunk => data += chunk)
req.on('end', () => {
  console.log('Data:', data)
  client.destroy()
})
req.end()

然后跑步：

→ node http2_client.js 
(node:34542) ExperimentalWarning: The http2 module is an experimental API.
Header: ":status" "200"
Header: "content-type" "application/json"
Header: "date" "Sat, 02 Dec 2017 23:27:21 GMT"
Data: {"alpnProtocol":"h2","httpVersion":"2.0"}

HTTP / 1客户端

const https = require('https')
const fs = require('fs')

var options = {
  method: 'GET',
  hostname: 'localhost',
  port: '8443',
  path: '/',
  protocol: 'https:',
  ca: fs.readFileSync('ca-crt.pem'),
  rejectUnauthorized: true,
  //agent: false
}

var req = https.request(options, function(res){
  var body = ''
  res.setEncoding('utf8')
  res.on('data', data => body += data)
  res.on('end', ()=> console.log('Body:', body))
})

req.on('response', response => {
  for (const name in response.headers) {
    console.log('Header: "%s" "%s"', name, response.headers[name])
  }
})

req.end()

然后运行

→ node http1_client.js 
Header: "content-type" "application/json"
Header: "date" "Sat, 02 Dec 2017 23:27:08 GMT"
Header: "connection" "close"
Header: "transfer-encoding" "chunked"
Body: {"alpnProtocol":false,"httpVersion":"1.1"}

HTTP / 2服务器

使用普通的HTTP / 2服务器将与http2_client一起使用，但是＆＃34;挂起＆＃34;对于http1_client。当您删除allowHTTP1: true时，将关闭来自HTTP / 1客户端的TLS连接。

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

var options = {
  key: fs.readFileSync('server-key.pem'), 
  cert: fs.readFileSync('server-crt.pem'), 
  ca: fs.readFileSync('ca-crt.pem'), 
  allowHTTP1: true,
}

var server = http2.createSecureServer(options)
server.on('error', error => console.log(error))
server.on('connect', conn => console.log('connect', conn))
server.on('socketError', error => console.log('socketError', error))
server.on('frameError', error => console.log('frameError', error))
server.on('remoteSettings', settings => console.log('remote settings', settings))

server.on('stream', (stream, headers) => {
  console.log('stream', headers)
  stream.respond({
    'content-type': 'application/html',
    ':status': 200
  })
  console.log(stream.session)
  stream.end(JSON.stringify({
    alpnProtocol: stream.session.socket.alpnProtocol,
    httpVersion: "2"
  }))
})

server.listen(8443)

证证书

通过要点中详述的扩展中间证书设置，需要将完整的CA证书链提供给客户端。

cat ca/x/certs/x.public.pem > caxy.pem
cat ca/y/certs/y.public.pem >> caxy.pem

然后在客户端中使用选项中的ca。

{ 
  ca: fs.readFileSync('caxy.pem'),
}

使用this circle.com article中的以下简单CA设置运行这些示例：

为了简化配置，让我们抓住以下CA. 配置文件。
wget https://raw.githubusercontent.com/anders94/https-authorized-clients/master/keys/ca.cnf
接下来，我们将使用它创建一个新的证书颁发机构配置。
openssl req -new -x509 \
  -days 9999 \
  -config ca.cnf \
  -keyout ca-key.pem \
  -out ca-crt.pem
现在我们在ca-key.pem和。中拥有我们的证书颁发机构 ca-crt.pem，让我们为服务器生成一个私钥。
openssl genrsa \
  -out server-key.pem \
  4096
我们的下一步行动是生成证书签名请求。再来一次简化配置，让我们使用server.cnf作为配置快捷方式。
wget https://raw.githubusercontent.com/anders94/https-authorized-clients/master/keys/server.cnf
现在我们将生成证书签名请求。
openssl req -new \
  -config server.cnf \
  -key server-key.pem \
  -out server-csr.pem
现在让我们签署请求。
openssl x509 -req -extfile server.cnf \
  -days 999 \
  -passin "pass:password" \
  -in server-csr.pem \
  -CA ca-crt.pem \
  -CAkey ca-key.pem \
  -CAcreateserial \
  -out server-crt.pem
