所以我在网络内部的不同服务器上有几个应用程序，我使用node.js和socket.io js来处理它们之间的实时通信，当每个单独运行时工作正常，但是当我放在应用程序1上的iframe内部的应用程序2我收到以下错误 “阻止具有原点的帧”http：// 192.128.1.97“访问具有原始”http：// intranet“的帧。协议，域和端口必须匹配。” *注意我在上面的网址中添加了空格，因为页面告诉我不允许链接。
有什么方法可以让iframe连接到socket.io？代码很简单，但这是服务器代码...

对于大量代码感到抱歉，但试图提供所有必需的conte4xt。本质上服务器已启动并运行，应用程序1连接并获取唯一的会话ID，然后当应用程序2尝试从iframe连接时，我得到上述错误，当应用程序2不在iframe中时，它连接正常并获得会话ID。请尽可能帮助，我无法弄清楚为什么它会被阻止，我真的需要这个并且正常运行。提前感谢您的任何帮助
