代理websocket
一、配置nginx
upstream wsbackend {
server 127.0.0.1:10000;
server 127.0.0.1:10000;
}
server {
listen 80;
server_name ws.peter-zhou.com;
location / {
proxy_pass http://wsbackend;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
二、websocket 服务调试
1、websocket server 实现（Python）
#! /usr/bin/env python
# -*- coding: utf-8 -*-
# vim:fenc=utf-8
#
# pip install bottle_websocket
# pip install bottle
from bottle import get, run, template
from bottle.ext.websocket import GeventWebSocketServer
from bottle.ext.websocket import websocket
import gevent
users = set()
@get('/')
def index():
return template('index')
@get('/websocket', apply=[websocket])
def chat(ws):
users.add(ws)
while True:
msg = ws.receive()
if msg is not None:
for u in users:
print type(u)
u.send(msg)
print u,msg
else: break
users.remove(ws)
run(host='xxx.xxx.xxx.xxx', port=10000, server=GeventWebSocketServer)
2、websocket client实现(html)
<html>
<head>
<script type="text/javascript" src="http://cdn.staticfile.org/jquery/1.11.0/jquery.min.js"></script>
<script>
$(document).ready(function() {
if (!window.WebSocket) {
if (window.MozWebSocket) {
windowwindow.WebSocket = window.MozWebSocket;
} else {
$('#messages').append("<li>Your browser doesn't support WebSockets.</li>");
}
}
ws = new WebSocket('ws://xxx.xxx.xxx.xxx:10000/websocket');
ws.onopen = function(evt) {
$('#messages').append('<li>Connected to chat.</li>');
}
ws.onmessage = function(evt) {
$('#messages').append('<li>' + evt.data + '</li>');
}
$('#send-message').submit(function() {
ws.send($('#name').val() + ": " + $('#message').val());
$('#message').val('').focus();
return false;
});
});
</script>
</head>
<body>
<form id="send-message" class="form-inline">
<input id="name" type="text" value="name">
<input id="message" type="text" value="contain" />
<button class="btn btn-success" type="submit">Send</button>
</form>
<div id="messages"></div>
</body>
</html>
三、测试
1、跳过nginx代理访问
直接修改为websocket地址，打开两个页面看是否能互相通信
2、访问nginx代理
修改为nginx上下游的域名，打开两个页面看是否能互相通信
