Hello
I have an applet that upload a file choosen by the user:
/**********************************************/
URL url = new
URL("http://192.168.0.1/put";);
conn = (HttpURLConnection)
url.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" +
boundary);
dos = new
DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens +
boundary + lineEnd);
dos.writeBytes(
"Content-Disposition: form-data; name=\"" + parameterName + "\";"
+
" filename=\""
+
fileName
+
"\""
+
lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum
size
bytesAvailable =
fileInputStream.available();
bufferSize =
Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into
form...
bytesRead =
fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable =
fileInputStream.available();
bufferSize =
Math.min(bytesAvailable, maxBufferSize);
bytesRead =
fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data
necesssary after file data...
dos.writeBytes(lineEnd);
if(extraParams != null) {
for(Enumeration
enum = extraParams.keys(); enum.hasMoreElements(); ) {
String param = (String)enum.nextElement();
String value = extraParams.getProperty(param);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes(
"Content-Disposition: form-data; name=\"" + param + "\";" +
lineEnd + lineEnd + value + lineEnd);
}
}
dos.writeBytes(twoHyphens +
boundary + twoHyphens + lineEnd);
// close streams
fileInputStream.close();
dos.flush();
dos.close();
int httpStatus =
conn.getResponseCode();
/********************************/
On the server side
/********************************/
server = HttpServer.create(new InetSocketAddress(port), 0);
server.createContext("/put", new PutHandler());
/********************************/
How should I implement PutHandler to store the file on the server ?
Thanks,
Guy Smadja
