//當單擊頁面中的某按鈕呼叫此方法時，瀏覽器直接彈出“另存為...”對話方塊， Chorme則直接下載該檔案
// 而不用其它頁面做中轉
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//取得輸出流
ServletOutputStream out = response.getOutputStream();request.setCharacterEncoding("UTF-8");
int
byte data[] = new byte[BUFFER];
BufferedInputStream bis = null;
FileInputStream fis = new FileInputStream(zipFileName);
int read;
bis = new BufferedInputStream(fis,BUFFER);
response.setContentType("application/OCTET-STREAM" );
//
檔名可以任意指定， 本例中輸出的檔名為 test.zip,
while((read = bis.read(data)) != -1){
out.write(data, 0, read);
}
fis.close();
bis.close();
}
