本地主机上的 ChatScript 机器人

Question

我使用聊天脚本创建了一个聊天机器人。当我执行 chatscript.exe 程序时，它在 .cmd 中完美运行。现在我正在尝试运行使用 xampp 浏览器的聊天机器人。我已经完成了以下步骤：

我已经在C盘安装了XAMPP
在 XAMPP > HTDOCS 文件夹中我添加了 Chatscript 文件夹。
我正在使用聊天脚本提供的更好的网络界面。
当我尝试运行 index.php 文件时，机器人没有回复。

请在网络界面中找到以下代码。 Index.php

请在下面找到问题的屏幕截图： Issue while accessing chatbot on localhost:8080

我在连接聊天脚本服务器和本地主机时遇到困难。请让我知道我应该在 UI.php 中更改什么，以便机器人发送回复。

提前致谢。

Answer 1

UI.php 文件中有一个错误。 $ret 变量因未声明而中断。如果您在 fputs 上方添加 $ret = ''; 代码应该有效：

 // write message to socket server
    $ret = '';
    fputs($fp,$msg);
    while (!feof($fp))
    {
        $ret .= fgets($fp, 512);
    }

    fclose($fp);
    exit($ret);
}

Answer 2

除了 $ret 更正之外，在运行 in XAMPP 之后，由于 Web 主机是 Apache，因此客户端在使用 CS over Web 时使用端口 8080 或 8088。 ChatScript 作为服务器，需要使用端口 1024（或用户自定义）启动 ChatScript 系统。此外，index.php文件中也调用了Harry Bot，改为ui.php文件中的Rose。做完这些我有CS回复。
