Question

从客户端向服务器发送数据时遇到问题 - Python websocket。这是我的客户代码：

<script type="text/javascript">
    var s = new WebSocket('ws://127.0.0.1:8999');
    s.onopen = function (e) {
        console.log("Socket opened.");
    };
    s.onclose = function (e) {
        console.log("Socket closed.");
    };
    s.onmessage = function(t){alert(t)};
    function onSubmit() {
        s.send("Hello from client");
    }
</script>

服务器 - Python代码：

import socket
import re
from base64 import b64encode
from hashlib import sha1

websocket_answer = (
    'HTTP/1.1 101 Switching Protocols',
    'Upgrade: websocket',
    'Connection: Upgrade',
    'Sec-WebSocket-Accept: {key} \r\n\r\n',
)

GUID = "258EAFA5-E914-47DA-95CA-C5AB0DC85B11"

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('127.0.0.1', 8999))
s.listen(10)

client, address = s.accept()
text = client.recv(1024)

print "Get data text from client and send back this data: "
print text

key = (re.search('Sec-WebSocket-Key:\s+(.*?)[\n\r\r\n]+', text)
    .groups()[0]
    .strip())

response_key = b64encode(sha1(key + GUID).digest())
response = '\r\n'.join(websocket_answer).format(key=response_key)

client.send(response)

clientData = client.recv(4096)
client.send("Hello from server")

运行Python Socket Server时，我可以从客户端连接，它的意思是“console.log（”Socket open。“）;”工作中。但是当我通过运行函数onSubmit（）数据从客户端向服务器发送数据时，我在Chrome开发工具的控制台日志中收到错误“无效的帧头”。当我从发送到服务器的客户端（Python文件中的clientData变量）调试数据时，我得到了一个破解字符串：“ Ϭ Ջ ߕ ܉ ”。有人可以帮我解决这个问题吗？
