Difference with and without enctype=“multipart/form-data” for html form in browser and server
<form action="upload" method="post" enctype="multipart/form-data">
<input type="text" name="description" />
<input type="file" name="file" />
<input type="submit" />
</form>
It is known that the code request.getParameter("description");
returns null
.
I do understand that I can get parameter like below explained here (How to upload files to server using JSP/Servlet?). But my question what is the difference while browser sent the data (Like how exactly the request is being constructed) to server with and without enctype="multipart/form-data"
or what is different handling done on server side while enctype
is set to multipart/form-data
List<FileItem> items = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
for (FileItem item : items) {
if (item.isFormField()) {
//my code
}
jsp servlets file-upload
