[英]CORS issues with Express, Socket.io and Nginx
我已經改編了一個教程,以在 Node.js 中進行簡單的 Socket.io 聊天。 它在本地托管時有效,但在將其推送到測試服務器后,我無法接受套接字連接。 似乎是與跨域相關的問題,盡管我對如何在 Nginx 中路由事物也有些困惑。 遵循相關問題中的建議沒有幫助。
客戶端腳本: var socket = io.connect('http://localhost/socket.io');
索引.js:
const express = require('express');
const app = express();
const path = require('path');
const httpServer = require('http').createServer(app);
const io = require('socket.io')(httpServer, {
cors:true,
origins:["*"],
// origins:["http://xxx.xxx.xxx.xxx:8080"],
// transports: ['websocket'],
});
const views_path = (__dirname + '/views');
app.set('views',views_path);
app.use(express.static(__dirname + '/public'));
app.get('/', function(req,res){
console.log('render request received');
res.render('startPage.ejs');
});
io.sockets.on('connection', socket => {
console.log('connection received.')
socket.on('username', function(username) {
socket.username = username;
io.emit('is_online', socket.username);
});
//...
});
httpServer.listen(8080);
nginx 站點可用:
server {
server_name campfire;
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/campfire/html;
index index.html index.htm index.nginx-debian.html;
location ^~ /assets/ {
gzip_static on;
expires 12h;
add_header Cache-Control public;
}
location / {
proxy_set_header Host $host;
#proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://localhost:8080;
}
location /socket.io/ {
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'Upgrade';
proxy_http_version 1.1;
#proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://localhost:8080/socket.io/;
}
}
歡迎任何見解!
進行此更改解決了問題:
客戶端腳本: var socket = io.connect();
這種方式使用帶有套接字的默認連接目標。
