WebSocket 客户端只能连接到本地主机上的我的服务器
我一直在玩网络套接字，并且制作了一个小客户端，并将其发布在网站上。当我尝试从网站（从我的计算机）连接到同一台计算机上的简单 Python 服务器时，它工作正常，连接到本地主机。但是我无法从另一台计算机连接。我在这里的很多问题中都看到了这个问题，但没有解决方案。根据此网站，问题可能无法解决。
另一种选择是socket.io，显然，我如何将它用于网络主机上的客户端？ GitHub socket.io 页面在安装方面相当模糊，至少对于像我这样的人来说是这样。
一个在本地工作的简单例子是：
# Python server
import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(("", 12345))
sock.listen(5)
newsock, addr = sock.accept()
print "Connection"
// Client
<script type = "text/javascript">
window.onload = function()
{
// Works
var sock = new WebSocket("ws://127.0.0.1:12345");
// Doesn't work
var sock = new WebSocket("ws://194.237.*.*:12345");
}
</script>
I've been playing with websockets, and I've made a little client that I've put up on a website. When I try to connect from the website ( from my computer ) to a simple Python server on the same computer it works fine, connecting to localhost. However I cannot connect from another computer. I've seen this problem in quite a few questions here, but no solutions. According to this website the problem probably can't be solved.
An alternative is socket.io, apparently, how can I use this for a client on a webhost? The GitHub socket.io page is quite vague on installation, at least for someone like me.
Well a simple example which works locally would be;
# Python server
import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(("", 12345))
sock.listen(5)
newsock, addr = sock.accept()
print "Connection"
// Client
<script type = "text/javascript">
window.onload = function()
{
// Works
var sock = new WebSocket("ws://127.0.0.1:12345");
// Doesn't work
var sock = new WebSocket("ws://194.237.*.*:12345");
}
</script>

您是否尝试过绑定到
0.0.0.0？Have you tried binding to
0.0.0.0?对我来说，问题是我没有打开 python 传入连接的防火墙。
For me, the problem was that I had not opened the firewall for incoming connections to python.
