这是最底层的，
嘿嘿，我 还是习惯搞个框架来实现急需要的功能。。。
这个东东玩得很有意思的。。
服务器端的代码：
import simplejson
import socket
import sys
import base64
import hashlib
import time
HOST = ‘127.0.0.1‘
PORT = 9000
MAGIC_STRING = ‘258EAFA5-E914-47DA-95CA-C5AB0DC85B11‘
HANDSHAKE_STRING = "HTTP/1.1 101 Switching Protocols\r\n" "Upgrade:WebSocket\r\n" "Connection: Upgrade\r\n" "Sec-WebSocket-Accept: {1}\r\n" "WebSocket-Location: ws://{2}/chat\r\n" "WebSocket-Protocol:chat\r\n\r\n"
def parse_data(msg):
v = ord(msg[1]) & 0x7f
if v == 0x7e:
p = 4
elif v == 0x7f:
p = 10
else:
p = 2
mask = msg[p:p+4]
data = msg[p+4:]
return ‘‘.join([chr(ord(v) ^ ord(mask[k%4])) for k, v in enumerate(data)])
def start():
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
try:
sock.bind((HOST, PORT))
sock.listen(100)
except Exception as e:
print(‘bind error‘)
print(e)
sys.exit()
while True:
conn, add = sock.accept()
try:
handshake(conn)
finally:
print(‘finally‘)
conn.close()
sock.close()
pass
def handshake(conn):
headers = {}
shake = conn.recv(1024)
print shake
if not len(shake):
print(‘len error‘)
return False
header, data = shake.split(‘\r\n\r\n‘, 1)
for line in header.split(‘\r\n‘)[1:]:
key, value = line.split(‘: ‘, 1)
headers[key] = value
if ‘Sec-WebSocket-Key‘ not in headers:
print(‘this is not websocket, client close.‘)
print headers
conn.close()
return False
sec_key = headers[‘Sec-WebSocket-Key‘]
res_key = base64.b64encode(hashlib.sha1(sec_key + MAGIC_STRING).digest())
str_handshke = HANDSHAKE_STRING.replace(‘{1}‘, res_key).replace(‘{2}‘, HOST + ":" + str(PORT))
print str_handshke
conn.send(str_handshke)
time.sleep(1)
conn.send(‘%c%c%s‘ % (0x81, 6, ‘suren1‘))
msg = conn.recv(1024)
msg = parse_data(msg)
print(‘msg : ‘ + msg)
time.sleep(1)
conn.send(‘%c%c%s‘ % (0x81, 6, ‘suren2‘))
msg = conn.recv(1024)
msg = parse_data(msg)
print(‘msg : ‘ + msg)
time.sleep(1)
conn.send(‘%c%c%s‘ % (0x81, 6, ‘suren3‘))
msg = conn.recv(1024)
msg = parse_data(msg)
print(‘msg : ‘ + msg)
return True
pass
if __name__ == ‘__main__‘:
try:
start()
except Exception as e:
print(e)
浏览器端的代码：
<html> <head>
<script type="text/javascript">
var socket = new WebSocket(‘ws://127.0.0.1:9000‘);
socket.onopen = function(e)
{
console.log(‘onopen : ‘ + e);
var element = document.getElementById("holder");
element.innerHTML += ‘onopen : ‘
element.innerHTML += e;
element.innerHTML += "<br>";
}
socket.onclose = function(e)
{
console.log(‘onclose : ‘ + e + ‘; length : ‘ + arguments.length);
var element = document.getElementById("holder");
element.innerHTML += ‘close : ‘
element.innerHTML += e;
element.innerHTML += "<br>";
}
socket.onmessage = function(e)
{
console.log(‘onmessage : ‘ + e + ‘; length : ‘ + arguments.length);
console.log(‘data : ‘ + e.data);
socket.send(‘chengang‘);
var element = document.getElementById("holder");
element.innerHTML += ‘onmessage : ‘
element.innerHTML += e
element.innerHTML += "<br>";
element.innerHTML += ‘data : ‘
element.innerHTML += e.data;
element.innerHTML += "<br>";
}
</script>
</head> <body>
<div id="holder" style="width:600px; height:300px"></div>
</body> </html>
效果图：
今天学习完工，应该是家庭，电影，小说的时间啦啦。。。
