I have a client application in Android which uses HttpURLConnection
to send files to the server. The server uses the Apache Commons FileUpload API to parse the form-data values.
The HttpURLConnection
sends this request:
-----------------------------4912995119421
Content-Disposition: form-data; name="deviceid"
9428103
-----------------------------4912995119421
Content-Disposition: form-data; name="countryid"
598
-----------------------------4912995119421
Content-Disposition: form-data; name="number"
98621360
-----------------------------4912995119421
Content-Disposition: form-data; name="file"; filename="2012-12-08 17.42.18.jpg"
Content-Type: image/jpeg

The server code:
String contentType = request.getContentType();
if ((contentType.indexOf("multipart/form-data") == -1)) {
response.setStatus(HttpServletResponse.SC_NOT_FOUND);
return;
}
long maxFileSize = (2 * 1024 * 1024);
int maxMemSize = (2 * 1024 * 1024);
DiskFileItemFactory factory = new DiskFileItemFactory();
// maximum size that will be stored in memory
factory.setSizeThreshold(maxMemSize);
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// maximum file size to be uploaded.
upload.setSizeMax(maxFileSize);
List fileItems = upload.parseRequest(request);
Iterator i = fileItems.iterator();
//leo primero todas las variables.
int deviceID = 0;
int countryID = 0;
String phoneNumber = "";
while (i.hasNext()) {
FileItem fi = (FileItem) i.next();
if (fi.isFormField()) {
String variable = fi.getFieldName();
if (variable.equals("deviceid")) {
deviceID = Integer.parseInt(fi.getString());
} else if (variable.equals("countryid")) {
countryID = Integer.parseInt(fi.getString());
} else if (variable.equals("number")) {
phoneNumber = String.valueOf(Long.parseLong(fi.getString()));
}
}
}
if (deviceID == 0 || countryID == 0 || phoneNumber.equals("")) {
response.setStatus(HttpServletResponse.SC_NOT_FOUND);
return;
}
The problem is in the line List fileItems = upload.parseRequest(request);
.
The returned list is empty and I can not get the form-data values.
