如何在使用Express / Socket.io的Node.js上使用HTTPS [英] How to use HTTPS on Node.js using Express/Socket.io
问题描述
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'）。服务器（凭证，应用程序）;
var io = require（'socket.io'）（https）;
https.listen（httpsPort，function（）{
logger.info（'listen 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（playingGames）{
logger.debug（playingGames）;
if（typeof playingGames =='undefined'）{
playingGames = 0;
} else {
playingGames = playingGames.games_played;
}
var spinsLeft = 10-playingGames;
res.json（{
spinsLeft：spinsLeft，
slots ：slot
}）;
}）;
}）;我的客户端的
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' （'Fehler bitte neu laden！'）;
}，3000）;
}）;
现在我在我的服务器上收到以下异常：
uncaughtException：缺少PFX或证书+私钥。
编辑：现在正在获取
不良请求
您的浏览器发送了一个此服务器无法理解的请求。
原因：你说的是普通HTTP到启用SSL的服务器端口。
请使用HTTPS方案访问此URL。
如果没有您的密钥和证书文件，我将提供一个使用Express，socket.io和https的例子。
首先我将创建密钥和证书文件，所以在目录下运行下列命令：
下面的命令将生成一个包含RSA密钥的文件。
$ openssl genrsa 1024> file.pem
在此您将被要求输入数据，但您可以留空，直到输入crs生成.pem。
$ openssl req -new -key file.pem -out csr.pem
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
所以在我的 app.js 文件，我正在设置和启动服务器通知，我使用文件 file.pem 和 file.crt 生成在最后一步：
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'，'这是来自黑暗的一个消息。'）;
}）;
server.listen（serverPort，function（）{
console.log（'server up and running at％s port'，serverPort）;
}）;
然后我的 public / index.html 我正在使用服务器：
<！doctype html>
< html>
< head>
< / head>
< body>
< h1>我还活着!!< / 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>
然后最后如果您从浏览器访问 https：// localhost ，您将看到一条来自websocket服务器的消息的警报。
Im trying to run my node server with https. I'm using express and socket.io.
This is my code for https:
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:
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:
uncaughtException: Missing PFX or certificate + private key.
EDIT: right now im getting
Bad Request
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.
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.
First I will create the key and cert files, so inside a directory run the following commands from your terminal:
The command below it is going to generate a file containing an RSA key.
$ 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.
$ openssl req -new -key file.pem -out csr.pem
Then a file.crt file will be created containing an SSL certificate.
$ openssl x509 -req -days 365 -in csr.pem -signkey file.pem -out file.crt
So in my app.js file where I am setting and starting the server notice that I am using the files file.pem and file.crt generated in the last step:
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.html where I am consuming the server:
<!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.
