java - GAE 1.7.2 的套接字连接错误

Question

我刚刚将我的应用程序更新到最新的 java GAE SDK 1.7.2，但出现以下错误。

ATTENTION: /_ah/channel/dev

看来我必须设置一些权限才能在这个新版本中使用 channel API。我找不到它的任何踪迹。

有人听说过这样的事情吗？

谢谢

Answer 1

这是 1.7.2 开发服务器中引入的错误。

有一个解决方法，请参阅错误中的“过滤器”解决方法。 http://code.google.com/p/googleappengine/issues/detail?id=8166

将在 1.7.3 中修复。
