我正在尝试创建一个基本的websocket服务器，服务器接收来自客户端的握手，但客户端似乎没有接受服务器的握手响应。 我对“Sec-WebSocket-Key”也有疑问，我认为散列值太长!谢谢:)
import socket
def handle(s):
print repr(s.recv(4096))
s = socket.socket()
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR,1)
s.bind(('',9876))
s.listen(2)
handshakes='\
HTTP/1.1 101 Web Socket Protocol Handshake\r\n\
Upgrade: WebSocket\r\n\
Connection: Upgrade\r\n\
WebSocket-Origin: null\r\n\
WebSocket-Location: ws://localhost:9876/\r\n\
'
def handshake(hs):
hslist = hs.split('\r\n')
body = hs.split('\r\n\r\n')[1]
key = ''
cc = '258EAFA5-E914-47DA-95CA-C5AB0DC85B11'
for h in hslist:
if h.startswith('Sec-WebSocket-Key:'):
key = h[19:]
else:
continue
print key
import hashlib
import base64
s = hashlib.sha1()
s.update(key+cc)
h = s.hexdigest()
print 's = ', s
print 'h = ', h
return base64.b64encode(h)
while True:
c,a = s.accept()
print c
print a
msg = c.recv(4096)
if(msg):
print msg
print 'sending handshake ...'
handshakes += 'Sec-WebSocket-Accept: '+str(handshake(msg))+'\r\n\r\n'
print handshakes
c.send(handshakes)
c.send('Hello !')
break;

客户端:
<!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:9876/");
s.onopen = function(e) { alert("opened"); }
s.onclose = function(e) { alert("closed"); }
s.onmessage = function(e) { alert("got: " + e.data); }
};
</script>
</head>
<body>
<div id="holder" style="width:600px; height:300px"></div>
</body>
</html>
服务器输出:

最佳答案
我认为您需要调用sha.digest()来代替hexdigest()。您想要将 20 字节的二进制哈希传递给您的 Base64 编码器； digest() 执行此操作，同时 hexdigest() 将这些字节中的每一个转换为 2 字节十六进制表示形式。
请参阅python sha docs了解详情。
