Question

我想知道是否有人可以帮我解决一个小问题，我试图用.NET中的Fleck Web套接字库和PHP来识别每个客户端

PHP：

if (isset($_POST['web_socket_username_submit'])) {
    $_SESSION['web_socket_username'] = $_POST['web_socket_username'];
    header("location: ");
}

if (!isset($_SESSION['web_socket_username'])) {
    echo 'You need to select a username before continuing, this username will stick with you untill you clean your cache.<br>';
    echo '<form name="webSocketUsernameForm" method="post">';
    echo '';
    echo '<input type="text" name="web_socket_username" placeholder="Username...">';
    echo '<input type="submit" name="web_socket_username_submit" value="Continue">';
    echo '</form>';
    exit();
}
?>

如果客户不被欺骗，我如何识别客户？

Answer 1

实现此目的的一种简单方法是使用socket.ConnectionInfo.Id，它为每个套接字返回一个唯一的GUID。
