Node.js HTTP2服务器错误:套接字挂起
给定具有实验HTTP2支持的最新版本的Node.js:
$ node -vv9.2.0
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')
}
并对此提出了要求:
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 upat 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rejectUnauthorized: true
设置,则错误:
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)
不知道出了什么问题以及为什么到了日志记录的地步stream
。
如果我进入浏览器并访问https://
localhost:8443,然后单击警告消息,则它实际上会记录stream
并成功发出请求。但是尚未能够使节点发出请求。
我想将其视为HTTP1服务器,因此不想使用HTTP2客户端发出请求。但是尝试使用相同的东西。
回答:
HTTP / 1与HTTP / 2共享的请求语义不同,因此需要在HTTP / 2服务器中检测并处理HTTP /
1客户端。为了同时支持两者,您需要使用HTTP2兼容性API。
当HTTP1客户端连接到具有allowHTTP1: true
设置的HTTP / 2服务器但不处理HTTP / 1请求时,将发生“挂起” 。
这些示例基于Node文档的示例代码。
回答:
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)
回答:
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()
然后运行:

回答:
使用纯HTTP / 2服务器可与一起使用,http2_client
但将“挂起”用于http1_client
。删除时,来自HTTP /
1客户端的TLS连接将关闭allowHTTP1: true
。
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)
回答:
根据要点中详细描述的扩展中间证书设置,需要将CA的完整证书链提供给客户端。
cat ca/x/certs/x.public.pem > caxy.pemcat ca/y/certs/y.public.pem >> caxy.pem
然后在客户端中使用此ca
选项。
{ ca: fs.readFileSync('caxy.pem'),
}
这些示例是使用来自circle.com的以下简单CA设置运行的:
为了简化配置,让我们获取以下CA配置文件。
wget https://raw.githubusercontent.com/anders94/https-authorized-
clients/master/keys/ca.cnf
接下来,我们将使用此配置创建一个新的证书颁发机构。
openssl req -new -x509 \
-days 9999 \
-config ca.cnf \
-keyout ca-key.pem \
-out ca-crt.pem
现在,我们已经在ca-key.pem和ca-crt.pem中拥有了证书颁发机构,现在让我们为服务器生成一个私钥。
openssl genrsa \
-out server-key.pem \
4096
我们的下一步是生成证书签名请求。再次简化配置,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
