用Uploadify上传文件 遇到错误：SecurityError #2156 null

使用swfupload出现SecurityError Error #2156问题

使用swfupload出现SecurityError Error #2156问题

原来网站是在一个服务器运行是正常的，上传文件也正常。但是当把网站迁移到另外一个服务器时，上传文件就会出现在这个错误：

2156

SecurityError

Error #2156

null

一直上传失败

检查了老半天，在网上也问了很多人，都说是目录权限错误，但我检查过后，是没有问题的。

最后在官网上看到如下的解释：

The same application published to server by two site,

one is OK, and other site show the error message, like this:

SWF DEBUG: ReturnUploadStart: Exception occurred: null

SWF DEBUG: Event: uploadError(): Upload Failed. Exception occurred: 2156

SWF DEBUG: SecurityError

SWF DEBUG: Error #2156

SWF DEBUG: null

SWF DEBUG: Event: uploadComplete : Upload cycle complete.

and in the page, the placehoader is white, no appoint image。who can tell me why?Thank you!

sorry, my English is not good!

I'm not sure what is triggering your error but here are some guesses:

1) You are uploading to a different domain (or port number) than that which hosts your swfupload.swf file.

2) You are loading swfupload.swf via https (SSL) but are using an HTTP url for your upload url.

If you must upload to a different domain you must place a crossdomain.xml file on your server. See Adobe's live docs for details on setting it up.

于是我改了一下网站的端口（原来是87，改为88）

呵呵。居然成功了，个人认为应该是Flash组件对我原来的这个端口不支持吧。
