我正在尝试允许下载位于文件系统上的 PDF。我有一个扩展 ActionSupport 的动作类 DownloadFileAction,它基本上执行以下操作:
public String execute() {
// lookup file
inputStream = new FileInputStream(file);
return SUCCESS;
}
public String getContentType() {
return "application/pdf";
}
public String getContentDisposition() {
return "attachment;filename=\"filename.pdf\"";
}
我的动作映射定义如您所料:
<action name="downloadFile" class="com.foo.DownloadFileAction">
<result name="success" type="stream">
<param name="allowCaching">false</param>
</result>
</action>
这在 Firefox 和 IE9 中运行良好,但在 IE8 中由于未知原因无法运行。有什么想法吗?
更新:使用 Live HTTP Headers 插件,我在 Firefox 中下载时看到了这一点。我认为这在 IE8 中是相同的:

更新:更多信息。我认为这可能与应用程序在 https 下运行的事实有关。这有帮助吗?
