How to use HTTPS on Node.js using Express/Socket.io
提问by kovogel
Im trying to run my node server with https. I'm using express and socket.io.
我正在尝试使用 https 运行我的节点服务器。我正在使用 express 和 socket.io。
This is my code for https:
这是我的 https 代码：
var httpsPort = 443;
var privateKey = fs.readFileSync(mykeypath');
var certificate = fs.readFileSync(mycertificatepath');
var credentials = {key: privateKey, cert: certificate};
var https = require('https').Server(credentials,app);
var io = require('socket.io')(https);
https.listen(httpsPort, function(){
logger.info('listening on *:' + httpsPort);
});
app.get('/initGame', function (req,res){
var slots = require('./slots.json', 'utf8');
var userObject = {
address : req.connection.remoteAddress,
userAgent : req.headers['user-agent']
};
db.getPlayedGames(userObject,function(playedGames){
logger.debug(playedGames);
if(typeof playedGames == 'undefined' ){
playedGames=0;
}else{
playedGames = playedGames.games_played;
}
var spinsLeft = 10-playedGames;
res.json({
spinsLeft: spinsLeft,
slots: slots
});
});
});
on my client its the following:
在我的客户上，它的内容如下：
var myServer = "//" + document.domain + ":443";
$.get( myServer + "/initGame", function(data) {
totalSpinsLeft = data.spinsLeft;
$('#trysLeft').text(totalSpinsLeft);
Seven.init(data.slots);
}).fail(function(){
setTimeout(function(){
$('#spinner2').text('Fehler bitte neu laden!');
},3000);
});
Right now im getting the following exception on my server:
现在我在我的服务器上收到以下异常：
uncaughtException: Missing PFX or certificate + private key.
uncaughtException: 缺少 PFX 或证书 + 私钥。
EDIT: right now im getting
编辑：现在我得到
Bad Request
错误的请求
Your browser sent a request that this server could not understand. Reason: You're speaking plain HTTP to an SSL-enabled server port. Instead use the HTTPS scheme to access this URL, please.
您的浏览器发送了此服务器无法理解的请求。原因：您对启用 SSL 的服务器端口使用纯 HTTP。请改用 HTTPS 方案访问此 URL。

It is hard to test your example without your key and cert files instead I am going to provide an example where I am using Express, socket.io, and https.
如果没有您的密钥和证书文件，很难测试您的示例，相反，我将提供一个示例，其中我使用 Express、socket.io 和 https。
First I will create the key and cert files, so inside a directory run the following commands from your terminal:
首先，我将创建密钥和证书文件，因此在目录中从终端运行以下命令：
The command below it is going to generate a file containing an RSA key.
下面的命令将生成一个包含 RSA 密钥的文件。
$ openssl genrsa 1024 > file.pem
Here you will be asked to input data but you can leave blank pressing enter until the crs.pem is generated.
在这里，您将被要求输入数据，但您可以按 Enter 键保留空白，直到生成 crs.pem。
$ openssl req -new -key file.pem -out csr.pem
Then a file.crt file will be created containing an SSL certificate.
然后将创建一个包含 SSL 证书的 file.crt 文件。
$ openssl x509 -req -days 365 -in csr.pem -signkey file.pem -out file.crt
So in my app.jsfile where I am setting and starting the server notice that I am using the files file.pemand file.crtgenerated in the last step:
因此，在我app.js设置和启动服务器的文件中file.pem，请注意我正在使用这些文件并file.crt在最后一步生成：
var fs = require('fs');
var https = require('https');
var express = require('express');
var app = express();
var options = {
key: fs.readFileSync('./file.pem'),
cert: fs.readFileSync('./file.crt')
};
var serverPort = 443;
var server = https.createServer(options, app);
var io = require('socket.io')(server);
app.get('/', function(req, res) {
res.sendFile(__dirname + '/public/index.html');
});
io.on('connection', function(socket) {
console.log('new connection');
socket.emit('message', 'This is a message from the dark side.');
});
server.listen(serverPort, function() {
console.log('server up and running at %s port', serverPort);
});
and then my public/index.htmlwhere I am consuming the server:
然后我public/index.html在哪里使用服务器：
<!doctype html>
<html>
<head>
</head>
<body>
<h1>I am alive!!</h1>
<script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/1.3.5/socket.io.js"></script>
<script>
var URL_SERVER = 'https://localhost:443';
var socket = io.connect(URL_SERVER);
socket.on('message', function(data) {
alert(data);
});
</script>
</body>
</html>
then finally if you access from the browser at https://localhost, you will see an alert with a message that is coming from the websocket server.
最后，如果您从 浏览器访问https://localhost，您将看到一个警告，其中包含来自 websocket 服务器的消息。

This is how I managed to set it up with express:
这就是我设法使用 express 进行设置的方式：
var fs = require( 'fs' );
var app = require('express')();
var https = require('https');
var server = https.createServer({
key: fs.readFileSync('./test_key.key'),
cert: fs.readFileSync('./test_cert.crt'),
ca: fs.readFileSync('./test_ca.crt'),
requestCert: false,
rejectUnauthorized: false
},app);
server.listen(8080);
var io = require('socket.io').listen(server);
io.sockets.on('connection',function (socket) {
...
});
app.get("/", function(request, response){
...
})
I hope that this will save someone's time.
我希望这会节省某人的时间。
