如何使用 Express/Socket.io 在 Node.js 上使用 HTTPS [英] How to use HTTPS on Node.js using Express/Socket.io
问题描述
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.
Im trying to run my node server with https. I'm using express and socket.io.
这是我的 https 代码:
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
});
});
});
在我的客户端上如下:
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);
});
现在我的服务器出现以下异常:
Right now im getting the following exception on my server:
uncaughtException:缺少 PFX 或证书 + 私钥.
uncaughtException: Missing PFX or certificate + private key.
现在我得到
错误请求
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.
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.
推荐答案
如果没有您的密钥和证书文件，很难测试您的示例，相反，我将提供一个使用 Express、socket.io 和 https 的示例.
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.
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:
First I will create the key and cert files, so inside a directory run the following commands from your terminal:
下面的命令将生成一个包含 RSA 密钥的文件.
The command below it is going to generate a file containing an RSA key.
$ openssl genrsa 1024 > file.pem
在这里您将被要求输入数据，但您可以保留空白并按 Enter 键，直到生成 crs.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
然后将创建一个包含 SSL 证书的 file.crt 文件.
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
<小时>
因此，在我设置和启动服务器的 app.js 文件中，请注意我正在使用文件 file.pem 和 file.crt 最后一步生成:
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);
});
然后是我使用服务器的 public/index.html:
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>
最后，如果您从 https://localhost 的浏览器访问，您将看到一个带有来自 websocket 服务器的消息的警报.
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.
