ข้อเสียของ JSP อีกตัวหนึ่งก็คือ อันนี้แหละครรับ ยังมีรูปแบบการอ่านยากเหมือน ASP ไม่มีผิด ลองดูวิธ๊นี้ครับ
Code (JSP-Java)
FileItemFactory factory = new DiskFileItemFactory();
// Set factory constraints
// factory.setSizeThreshold(yourMaxMemorySize);
// factory.setRepository(yourTempDirectory);
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload( factory );
// upload.setSizeMax(yourMaxRequestSize);
// Parse the request
List<FileItem> uploadItems = upload.parseRequest( request );
for( FileItem uploadItem : uploadItems )
{
if( uploadItem.isFormField() )
{
String fieldName = uploadItem.getFieldName();
String value = uploadItem.getString();
}
}
