为什么尝试建立网络套接字时连接被拒绝？
[英]Why is connection refused when trying to establish a web-socket?
问题描述
I'm attempting to set up a web-socket connection between a java script client and a php server.
我正在尝试在 java 脚本客户端和 php 服务器之间建立 Web 套接字连接。 However, whenever I try to connect I get the error "connection refused".但是，每当我尝试连接时，都会收到错误“连接被拒绝”。
I am already able to create a web-socket connection between two php scripts which makes me think the server side code is correct.我已经能够在两个 php 脚本之间创建 web-socket 连接，这让我认为服务器端代码是正确的。
Please explain how I can fix this problem.请解释我如何解决这个问题。
Server (PHP):服务器（PHP）：
$host = "108.167.140.91";
$port = 5353;
set_time_limit(30);
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n");
// bind socket to port
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
// start listening for connections
$result = socket_listen($socket, 20);
// accept incoming connections
// spawn another socket to handle communication
$spawn = socket_accept($socket) or die("Could not accept incoming connection\n");
socket_write($spawn, "connected", strlen ("connected"));
// close sockets
socket_close($spawn);
socket_close($socket);
Client (HTML):客户端（HTML）：
<html>
<script>
var socket = new WebSocket("ws://108.167.140.91:5353");
// Open the socket
socket.onopen = function(event) {
console.log("connected");
// To close the socket....
socket.close()
};
</script>
</html>
You can test it for yourselves here:你可以在这里自己测试：

Try changing the host to "0.0.0.0".... that means it can accept socket connections requests from any host.尝试将主机更改为“0.0.0.0”......这意味着它可以接受来自任何主机的套接字连接请求。
