SWF上传IO错误
我在我的网站中使用 SWFUpload 来上传文件。一位用户在所有浏览器中始终出现 IO 错误，这使我得出结论：他的闪存一定已损坏。
但我们有什么办法可以检测到这一点，以便我可以给他提供替代品。
在创建swfupload对象时，有什么方法可以调用服务器并检查flash是否能够成功连接到服务器。
I am using SWFUpload in my website for uploading files. One of the user is consistently getting IO error across all browser which leads me to the conclusion that his flash must be corrupt.
But is there any way by which we can detect this so that I can give him alternates.
While creating the swfupload object, is there any way by which we can make a call to the server and check if the flash is able to make a successfull connection to the server.

我在诊断这个问题时也遇到了问题。后来它出现在两台 64 位 Windows 7 机器上。所有浏览器都出现IO错误，它们是新安装的，播放器是最后一个版本。
在尝试了来自网络的多种修复后，此修复有效：
Flash 播放器将安装在 chrome 上，但不会安装在 Firefox 上，因此您必须在其上再次安装播放器。进行相同的安装并且现在可以工作，这很奇怪，但我想从 IE 进行的安装一定有更多的魔力。
观察到的一个问题：如果没有签名证书，swfupload 将无法在 SSL 下工作，这是 swfupload 论坛上讨论的一个已知问题。
I also been having problem diagnosing this problem. Later occurrences of it have been on two 64bit windows 7 machines. The IO error appeared on all browsers, they were freshly installed, and the player was the last version.
After trying several fixes from the web, this one worked:
The flash player will be installed on chrome but not on Firefox, so you will have to install the player again on it. It is strange doing the same installation and now working, but i guess the installation from IE must have more mojo on it.
One issue observed: the swfupload will not work under SSL if there is no signed certificate, this is a known issue discussed on the swfupload forum.
