问题描述
我正在使用JSP将blob文件从HTML表单上传到MySQL数据库。我需要将文件名插入DB。我知道文件名存储在Content-Disposition标题中,我怎么能得到它?提前致谢!
I'm uploading a blob file from HTML form to MySQL database using JSP. I need to insert the filename into DB. I know that the filename is stored in the Content-Disposition header, how could I get that? Thanks in advance!
推荐答案如果您使用带有 HttpServletRequest.getPart :
Part part = request.getPart("xxx"); // input type=file name=xxx String disposition = part.getHeader("Content-Disposition"); String fileName = disposition.replaceFirst("(?i)^.*filename=\"?([^\"]+)\"?.*$", "$1");参见部分。
As @ Marc提到我没有处理URL编码。(他还使文件名周围的引号可选。)
As @Marc mentioned I did not treat URL encoding. (He also made the quotes around the filename optional.)
fileName = URLDecoder.decode(fileName, StandardCharsets.ISO_8859_1);未选中,但标头的HTTP编码应为默认ISO -8859-1。
Not checked, but HTTP encoding for headers should be the default ISO-8859-1.
