nginx as webserver incl。 socket.io和node.js / ws：// 400 Bad Request
我有这个错误请求。
德语的最后一句话的意思是“Firefox无法连接到位于ws：// …….”的服务器。
服务器不会是我想的问题。
因为这里是nginx的configuration，因为我觉得有问题！
server { server_name example.org; listen 80 default_server; root /var/www/web; location / # for symfony2 { try_files $uri @rewriteapp; } location @rewriteapp # for symfony2 { rewrite ^(.*)$ /app.php/$1 last; } location ~ ^/app\.php(/|$) { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_split_path_info ^(.+\.php)(/.*)$; include fastcgi_params; fastcgi_param HTTPS off; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; } location ~ ^/socket { proxy_pass http://127.0.0.1:8080; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $http_host; } access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; } nginx版本：nginx / 1.4.7
app.js（即服务器！）
var express = require('express'), io = require('socket.io').listen(server), server = require('http').createServer(app), bodyParser = require('body-parser'); var app = express(); server.listen(8080); app.use(bodyParser.json()); app.post('/', function(request, response) { response.send('OK'); io.emit('MessageForAll', request.body); }); io.on('connection', function (socket){}); console.log('Server running on port 8080.');
-
Nginx（nginx版本：nginx / 1.4.6）更改： –
server { listen 80; server_name 255717070.com; root /var/www/stack/25571070; index index.html index.htm; location / { } location ^~ /socket { rewrite ^/socket/(.*) /$1 break; #used to send request to base url proxy_pass http://127.0.0.1:3000; proxy_redirect off; proxy_pass_request_headers on; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $host; } }
注意：您需要将location ~ ^/socket更改为location ^~ /socket
节点更改：
-
app.js：
app.enable('trust proxy'); app.set('port', process.env.PORT || 3000); var server = app.listen(app.get('port'), function() { debug('Express server listening on port ' + server.address().port); }); var sockets = require('socket.io')({ 'transports': ['websocket', 'flashsocket','htmlfile','xhr-polling','jsonp-polling'] }); var io = sockets.listen(server,{ resource: '/socket.io/','sync disconnect on unload':true }); io.sockets.on('connection', function (socket) { setInterval(function() {socket.emit('news', { hello: 'hello world' })}, 1000); }); -
index.ejs：
<!DOCTYPE html> <html> <head> <title><%= title %></title> <link rel='stylesheet' href='/socket/stylesheets/style.css' /> </head> <body> <h1><%= title %></h1> <p>Welcome to <%= title %></p> <div id="divID"> </div> <script src="http://www.25571070.com/socket/socket.io/socket.io.js"></script> <script> var socket = io.connect('ws://25571070.com'); //var socket = io.connect('http://www.25571070.com'); var i = 0; socket.on('news', function(data) { var div = document.getElementById('divID'); i = i + 1; div.innerHTML = div.innerHTML + '<p>'+ data.hello+'('+i+')'+'</p>'; console.log(data); }); </script> </body> </html>
的package.json：
{ "name": "25571070", "version": "0.0.0", "private": true, "scripts": { "start": "node ./bin/www" }, "dependencies": { "body-parser": "~1.6.6", "cookie-parser": "~1.3.2", "debug": "~1.0.4", "ejs": "~0.8.5", "express": "~4.8.6", "moment": "^2.8.2", "morgan": "^1.2.3", "serve-favicon": "^2.0.1", "socket.io": "^1.0.6", "stylus": "0.42.3" } }
Firefox响应：
Chrome响应：
仅供参考。 我用下面的版本：
- “节点”：“v0.10.31”
- “ejs”：“〜0.8.5”
- “express”：“〜4.8.6”，
- “socket.io”：“^ 1.0.6”
- “nginx”：“1.4.6”
快速入门使用node.js转到node.js-socket.io-express-ngnix-starter
我可以看到服务器代码吗？
您是否仔细检查过websocket端口是否被任何防火墙阻止？
我想你已经读过这个博客文章了 ，对吗？
