我使用 Angular8 作为前端,使用 Nodejs 作为后端
我已经在生产中配置了 WSS,但与客户端的连接无法正常工作,在一个页面上连接正常,但在另一个页面上连接不工作。
websocket 和服务器在同一端口上运行
使用 Ws(localhost) 一切正常
我们在后端使用的包
https://www.npmjs.com/package/ws
后端代码:
express = require('express');
app = express();
const http = require('http');
const port = 8080;
const fs = require('fs');
const certificate = {
cert: fs.readFileSync(''),
key: fs.readFileSync('')
}
const httpServer = http.createServer(app,certificate);
var server = require('ws');
var s = new server.Server({ server:httpServer },{
rejectUnauthorized: false
});
s.on('connection', function (ws) {
ws.on('message', function (message) {
var obj = JSON.parse(message);
if (obj.messagetype == "test") {
//send data
}
}
}
httpServer.listen(port);
前端代码
export class WebsocketService {
constructor() { }
private subject: Rx.Subject<MessageEvent>;
public connect(url): Rx.Subject<MessageEvent> {
if (!this.subject) {
this.subject = this.create(url);
}
return this.subject;
}
private create(url): Rx.Subject<MessageEvent> {
let ws = new WebSocket(url);
let observable = Rx.Observable.create((obs: Rx.Observer<MessageEvent>) => {
ws.onmessage = obs.next.bind(obs);
ws.onerror = obs.error.bind(obs);
ws.onclose = obs.complete.bind(obs);
return ws.close.bind(ws);
});
let observer = {
next: (data: Object) => {
if (ws.readyState === WebSocket.OPEN) {
ws.send(JSON.stringify(data));
}
}
};
return Rx.Subject.create(observer, observable);
}
}
const CHAT_URL = "wss://cen.abcuae.com/";
export class SockoneService {
public messages: Subject<Message>;
public messages2: Subject<Message>;
constructor(wsService: WebsocketService) {
this.messages = <Subject<Message>>wsService.connect(CHAT_URL).pipe(map(
(response: MessageEvent): Message => {
let data = JSON.parse(response.data);
return data;
}));
this.messages2 = this.messages;
}
这是 /etc/nginx/sites-available/default 下的配置
server {
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/cen.abcuae.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/cen.abcuae.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
server_name cen.abcuae.com;
location / {
proxy_pass http://0.0.0.0:8080; #whatever port your app runs on
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_read_timeout 3600;
}
}
server {
listen 443;
listen [::]:443 ssl;
server_name cen.abcuae.com;

ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by C
location /websocket {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass https://cen.abcuae.com:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
答案1
express = require('express');
app = express();
//Use Here https
const http = require('https');
const port = 8080;
const fs = require('fs');
const certificate = {
cert: fs.readFileSync(''),
key: fs.readFileSync('')
}
const httpServer = http.createServer(app,certificate);
var server = require('ws');
var s = new server.Server({ server:httpServer },{
rejectUnauthorized: false
});
s.on('connection', function (ws) {
ws.on('message', function (message) {
var obj = JSON.parse(message);
if (obj.messagetype == "test") {
//send data
}
}
}
