Я попытался реализовать свой первый пример с веб-сокетом, но не могу заставить его работать.
Я использую веб-сервер Python:
import threading
import socket
def start_server():
tick = 0
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(('localhost', 1234))
sock.listen(100)
while True:
print 'listening...'
csock, address = sock.accept()
tick+=1
print 'connection!'
handshake(csock, tick)
print 'handshaken'
while True:
interact(csock, tick)
tick+=1
def send_data(client, str):
#_write(request, '\x00' + message.encode('utf-8') + '\xff')
str = '\x00' + str.encode('utf-8') + '\xff'
return client.send(str)
def recv_data(client, count):
data = client.recv(count)
return data.decode('utf-8', 'ignore')
def handshake(client, tick):
our_handshake = "HTTP/1.1 101 Web Socket Protocol Handshake\r\n"+"Upgrade: WebSocket\r\n"+"Connection: Upgrade\r\n"+"WebSocket-Origin: http://localhost:8888\r\n"+"WebSocket-Location: "+" ws://localhost:1234/websession\r\n\r\n"
shake = recv_data(client, 255)
print shake
#We want to send this without any encoding
client.send(our_handshake)
def interact(client, tick):
data = recv_data(client, 255)
print 'got:%s' %(data)
send_data(client, "clock ! tick%d" % (tick))
send_data(client, "out ! %s" %(data))
if __name__ == '__main__':
start_server()
И HTML:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Web Socket Example</title>
<meta charset="UTF-8">
<script>
window.onload = function() {
var s = new WebSocket("ws://localhost:1234/");
s.onopen = function(e) { s.send('Ping'); }
s.onmessage = function(e) { alert("got: " + e.data); }
s.onclose = function(e) { alert("closed"); }
};
</script>
</head>
<body>
<div id="holder" style="width:600px; height:300px"></div>
</body>
</html>
Когда я указываю своему браузеру http://localhost/websocket.html через apache2
, я получаю следующую ошибку:
python websocketserver.py
listening...
connection!
GET / HTTP/1.1
Upgrade: websocket
Connection: Upgrade
Host: localhost:1234
Origin: http://localhost
Sec-WebSocket-Key: A4sVkUhjVlTZbJrp2NUrqg==
Sec-WebSocket-Version: 13
handshaken
got:
Traceback (most recent call last):
File "websocketserver.py", line 43, in <module>

send_data(client, "out ! %s" %(data))
File "websocketserver.py", line 24, in send_data
return client.send(str)
socket.error: [Errno 32] Broken pipe
Может кто-нибудь помочь мне исправить это?
Спасибо
