我正在尝试在我的Java Servlet中提供二进制响应。首先,我从数据库获取请求的数据,然后尝试将其设置为如下响应:
ResultSet rset = (ResultSet) stmt.executeQuery();
if (rset.next())
{
byte[] bData = rset.getBytes("Soubor");
String sJmenoSouboru = rset.getString("Jmeno_souboru");
response.setHeader("Content-Disposition","attachment;filename=" + sJmenoSouboru);
//response.setHeader("Content-Description", sJmenoSouboru);
response.setHeader("Content-Transfer-Encoding", "binary");
//response.setContentType("application/pdf");
response.setContentType("application/octet-stream");
ServletOutputStream hOutStream = response.getOutputStream();
hOutStream.write(bData);
hOutStream.flush();
hOutStream.close();
}
这很好用,直到文件名中有'§'字符为止。比我得到ERR_SPDY_PROTOCOL_ERROR。据我所知,提到的字符应该在文件名中可用。有人知道,问题可能出在哪里?
答案 0 :(得分:0)
正如评论中的stdunbar所述,问题在于'§'是非ASCII字符,需要在文件名中转义。我通过更改以下代码行解决了该问题:
String sJmenoSouboru = URLEncoder.encode(rset.getString("Jmeno_souboru"), StandardCharsets.UTF_8.toString());
