我想要做的是在Powerpoint中打开下载的文件.
我现在的问题是,如果有一个标题设置,以便使用正确的应用程序打开此文件(在本例中为Powerpoint)
最佳答案
只需尝试正确设置Content Type标头,如果是pptx,则为application / vnd.openxmlformats-officedocument.presentationml.presentation,如下所示：
原文链接：https://www.f2er.com/spring/437344.htmlresponse.setContentType(
"application/vnd.openxmlformats-officedocument.presentationml.presentation"
);
response.setHeader(
"Content-Disposition",String.format("inline; filename=\"%s\"",documentFile.getFileName())
);
response.setContentLength((int) new File(filePath).length());
