连接到'的WebSocket；ws://192.168.5.78:8080/Chat-WebSocket/server.php'；失败：建立连接时出错：网络：：错误\u连接\u被拒绝

大家好,， 我正在尝试通过web套接字进行连接，以取代我的项目中的ajax日志轮询，因为它有太多的开销，尝试了一个简单的websocket聊天代码，问题是我无法在浏览器控制台中执行get-following错误时进行握手 到“ws://192.168.5.78:8080/Chat WebSocket/server.php”的WebSocket连接失败：建立连接时出错：net:：ERR_connection_拒绝

我已在本地计算机客户端上设置客户端代码：

服务器代码位于另一台本地计算机上

如何运行服务器？使用Apache：我有两台本地计算机，一台用作客户端，另一台用作服务器，不会启动服务器。你必须让它运行，这样你才能连接到它。这意味着您的PHP服务器脚本必须在尝试连接之前运行。服务器已处于运行状态：使用xampp控制面板
