Question

我写这个程序但不能在某些borwser工作，如IE（8） **为什么IE（8）显示错误的FileName？**换句话说它改为unicode名称！

当使用显式名称时，它的工作正确，但当我使用“fileName”时，它无法正常工作我的源代码

请帮帮我非常感谢

只有Chrome显示正确的结果！

Answer 1

问题在于Internet Explorer处理包含Unicode字符的文件名与Chrome之类的其他浏览器不同。不幸的是，没有简单的跨浏览器解决方案。

我们已使用此问题中讨论的解决方案解决了问题：How to encode the filename parameter of Content-Disposition header in HTTP?
