Simple HTTP(S) Response on WebSocket (WSS) Server
问题
我正在端口443上运行一个带证书的WebSocket（wss）服务器。为此，我在Node.js中使用了“https”和“ws”模块（简化版）：
require(__dirname + './config.js');
const https = require('https');
const WebSocketServer = require('ws');
const server = new https.createServer({
key: fs.readFileSync('./privkey.pem'),
cert: fs.readFileSync('./fullchain.pem')
});
const wss = new WebSocketServer.Server({ server: server });
wss.on("connection", function (socket) {
const c_inst = new require('./client.js');
const thisClient = new c_inst();
thisClient.socket = socket;
thisClient.initiate();
socket.on('error', thisClient.error);
socket.on('close', thisClient.end);
socket.on('message', thisClient.data);
});
server.listen(config.port, config.ip);
wss通信运行完美！但如果我在浏览器中通过https打开wss URL，我会收到一个超时错误（错误代码524），因为对于“正常”的（https/get）请求没有响应。
如何在我的wss服务器中为这种情况实现响应呢？
我只想发送一个简单的文本或HTML响应，如“这是一个WebSocket服务器”，或者如果有人通过浏览器/https连接到wss套接字，可以执行重定向到另一个URL。
谢谢！
英文:
I am running a websocket (wss) server (with certificate) on port 443. For this i am using the "https" and "ws" module in nodejs (simplified):
require(__dirname + './config.js');
const https = require('https');
const WebSocketServer = require('ws');
const server = new https.createServer({
key: fs.readFileSync('./privkey.pem'),
cert: fs.readFileSync('./fullchain.pem')
});
const wss = new WebSocketServer.Server({server: server});
wss.on("connection", function(socket){
const c_inst = new require('./client.js');
const thisClient = new c_inst();
thisClient.socket = socket;
thisClient.initiate();
socket.on('error', thisClient.error);
socket.on('close', thisClient.end);
socket.on('message', thisClient.data);
});
server.listen(config.port, config.ip);
The wss communication works perfect! But if i open the wss url via https:// in the browser i get a timeout error (Error code 524) because there is no response for a "normal" (https/get) request.
How can i implement a response for this case in my wss server?
I just want to send a response with a simple text or html like "This is a websocket server" or do a redirect to another url if someone connects to the wss socket via browser/https.
Thanks!

查看Node.js上的HTTPS服务器文档。
https://nodejs.org/api/https.html#httpscreateserveroptions-requestlistener
在创建服务器时，需要添加请求监听器。
const server = new https.createServer(
{
key: fs.readFileSync('./privkey.pem'),
cert: fs.readFileSync('./fullchain.pem')
},
(req, res) => {
res.writeHead(200);
res.end('This is a websocket server\n');
// 进行重定向或其他操作
}
);
英文:
See the documentation for HTTPS server on node.
https://nodejs.org/api/https.html#httpscreateserveroptions-requestlistener
You need to add request listener when you create a server.
const server = new https.createServer(
{
key: fs.readFileSync('./privkey.pem'),
cert: fs.readFileSync('./fullchain.pem')
},
(req, res) => {
res.writeHead(200);
res.end('This is a websocket server\n');
// do redirects or whanever you want
}
);
