用java流下载txt文件,通过report_download.action请求去下载弹出保存框中文件名是report_download.action,且能打开是在ie中直接打开,不能进行保存是什么原因???

五码无真相。

我做过类似的,你配置有问题吧,我给你找找代码
------解决方案--------------------------------------------------------
- Java code
response.setContentType("text/plain");response.setHeader("Content-Disposition", "attachment; filename=\"" + URLEncoder.encode(fileName, "UTF8").replace("+", "%20") + "\"");
------解决方案--------------------------------------------------------
"UTF8"->"UTF-8"
------解决方案--------------------------------------------------------
既然能出来文件下载框,怎么会不能打开或者保存呢。。。
出来框后好像就是windows干的事了吧。

这是下载请求action,前台传过来文件名和路径即可,
- Java code
