我在家庭网络中的覆盆子PI上运行pytHon服务器，设置简单。在我的电脑上我有一个基本的HTML页面，有一些Javascript tHat s可以与我的覆盆子pi上的py服务器进行通信。服务器上的覆盆子pi工作完美wHen从我的PC上的telnet测试。
这是PytHon代码：
import socket
from time import*
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = ""
port = 51025
s.bind((host, port))
s.listen(1)
conn, addr = s.accept()
print "Connection open"
print conn, addr
while 1:
data = conn.recv(4096)
if data:
print "msg received"
conn.sendall(data +" 12 uniflu")
else:
print "connection lost"
s.listen(1)
conn, addr = s.accept()
print "Connection open"
print conn, addr
这是javascript代码：
window.onload = function() {
// Get references to elements on the page.
var form = document.getElementById('message-form');
var messageField = document.getElementById('message');
var messagesList = document.getElementById('messages');
var socketStatus = document.getElementById('status');
var closeBtn = document.getElementById('close');
var openBtn = document.getElementById('open');
// The rest of the code in this tutorial will go here...
// Create a new WebSocket.
var socket = new WebSocket('ws://192.168.0.81:51025');
// Close the WebSocket connection when the close button is clicked.
// Show a connected message when the WebSocket is opened.
socket.onopen = function(event) {
socketStatus.innerHTML = 'Connected to: ' + event.currentTarget.URL;
socketStatus.className = 'open';
};
// Handle any errors that occur.
socket.onerror = function(error) {
console.log('WebSocket Error: ' + error);
};
// Close the WebSocket connection when the close button is clicked.
closeBtn.onclick = function(e) {
e.preventDefault();
// Close the WebSocket.
socket.close();
return false;
};
// Show a disconnected message when the WebSocket is closed.
socket.onclose = function (event) {
var reason;
alert(event.code);
// See http://tools.ietf.org/html/rfc6455#section-7.4.1

};
当我在我的firefox浏览器中加载HTML页面时，我可以看到通过打印输出在pytHon中建立连接，但是在服务器变得没有响应之后。我还在浏览器中看到错误消息1006。有谁知道他的区域，可以帮助我吗？它是什么从putty而不是从Web浏览器中运行得很好？
