＆QUOT;错误＃2038＆QUOT; ：当文件上传的柔性 [英] "Error #2038" : while file upload in flex
本文介绍了＆QUOT;错误＃2038＆QUOT; ：当文件上传的柔性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想通了一个错误，因为错误＃2038对的ioEvent，而文件中的柔性上传。
我GOOGLE了，但我没有找到任何合适的解决方案可能是如何实现这一点。在code正常工作了。但现在它显示出此错误。
这是IE浏览器的工作，但在其他浏览器中的显示错误。
任何机构有主意吗？
好这里是AS3 code ......请看看

解决方案
嘿，我终于得到了解决。如果任何机构面临着这样的问题，请遵循一些基本的步骤
在这里，我面对的是文件上传功能在IE浏览器（所有版本），但问题它不工作在其他浏览器。
然后按照以下步骤
-
- 首先尝试调度HTTPStatusEvent
-
- 检查什么错误来了。如果URL是有效的它不会给错误其他明智的，它会显示错误responseURL = NULL
-
- 然后检查你的服务器端脚本路径（您使用上传的文件什么的）
-
- 在我来说，我已经通过了完整的URL的文件的路径不一样（资产/.../ fileuploader.php）
- - 那么错误将得到解决
您会发现在互联网上的许多解决方案。但大多数情况下，检查filereference.IOerrorevent和放大器; filereference.HTTPStatusEvent
请参考以下链接：

I figured out an error as Error #2038 for IOEvent while file uploading in flex.
I googled out but i didn't find any proper solution may be how to implement that. The code is working properly before. But now its showing this error.
This is working in IE but in other browsers its showing error.
Any body having idea ?

The error

解决方案
Hey finally i got the solution. If any body facing like this problem please follow the some basic steps
Here the problem i faced is the file is uploading in IE(All version) but its not working in other browsers.
Then follow these steps
-- First try dispatching the HTTPStatusEvent
-- Check what error is coming. If the URL is valid it will not give error other wise it will show error responseURL=null
-- Then check your server side script path (what you are using to upload the file)
-- In my case i have passed the full URL for the file as a path not like (assets/.../fileuploader.php)
- -- Then the error will be solved
You will find many solution on internet. But the most of the cases to check filereference.IOerrorevent & filereference.HTTPStatusEvent
