我正在构建一个实时Web应用程序。
我只想连接客户端，使用sockjs识别并向服务器发送不同的消息
我们到目前为止所做的是从浏览器连接并发送一条消息，我回答了同一台服务器。
server.py
# -*- coding: utf-8 -*-
from sockjs.tornado import SockJSRouter, SockJSConnection
from tornado import web, ioloop
class ConnectionHandler(SockJSConnection):
def on_open(self, info):
print 'new connection'
def on_message(self, msg):
print str("server receives: %s" % msg)
self.send(u"server responds: %s" % msg)
if __name__ == "__main__":
onopen = SockJSRouter(ConnectionHandler, r"/websocket")
application = web.Application(onopen.urls)
application.listen(8686)
ioloop.IOLoop.instance().start()
client.html
<!DOCTYPE html>
<html>
<head>
<title>SockJS</title>
</head>
<script src="http://cdn.sockjs.org/sockjs-0.3.min.js"></script>
<script>
con = new SockJS('http://localhost:8686/websocket');
con.onmessage = function(evt){
x = document.createElement("p");
x.innerHTML = evt.data;
document.getElementById("msgbox").appendChild(x);
}
function DispatchText(){
var userInput = document.getElementById("message").value;
document.getElementById("message").value = "";
x = document.createElement("p");
x.innerHTML = "message sent: " + userInput;
document.getElementById("msgbox").appendChild(x);
con.send(userInput);
}
</script>
<body>
<p style="width: 800px">Use form to communicate with the server.</p>
<div id="msgbox" style="font-size: 14pt; height: 500px; width: 800px; overflow: scroll; border: 1px solid black"></div>
<form id="communication" onsubmit="DispatchText()" action="javascript:void(0);">
<input type="text" id="message" name="message" autocomplete="off" style="width:700px" />
<input type="submit" id="sub" name="sub" value="send" style="width:90px" />
</form>
</body>
</html>
如何识别每个客户？
将消息发送给所有连接的客户端？
答案 0 :(得分：1)
您需要保留连接列表。现在，当收到消息时，它将被发送到所有连接的客户端：
class ConnectionHandler(SockJSConnection):
connections = set()
def on_open(self, info):
print 'new connection'
self.connections.add(self)
def on_message(self, msg):
print str("server receives: %s" % msg)
for conn in self.connections:
conn.send(u"server responds: %s" % msg)
# Note you could also use self.broadcast(self.connections, msg)
def on_close(self):
self.connections.remove(self)
