Ya i know. After this above code i am using "buffer" value to post the data as follows:
public byte[] getBody() {
ByteVector buff = new ByteVector();
for (int i = 0; i < parameters.size(); i++) {
RequestParam param = (RequestParam) parameters.elementAt(i);
if (param instanceof BinaryRequestParam)
{
appendArray(buff, getBinaryHeader((BinaryRequestParam)param));
appendArray(buff, ((BinaryRequestParam)param).getData());
appendArray(buff, CRLF.getBytes());
} else {
appendArray(buff, postParameter(param.getName(), param.getValue()));
}
}
appendArray(buff, closeBoundary().getBytes());
return buff.getArray();
}
//for string values//
==============
private static String postParameterAsString(String name, String value) {
String result = boundary() + CRLF;
result = result + "Content-Disposition: form-data; name=\"" + name + "\"" + CRLF + CRLF;
result = result + value + CRLF;
return result;
}
//for image//
==========
private byte[] getBinaryHeader(BinaryRequestParam param) {
String header = boundary() + CRLF;
header += "Content-Disposition: form-data; filename=\"" + param.getName() + "\"" + CRLF+ CRLF;
header+= ((BinaryRequestParam)param).getData()+CRLF;
// header += "Content-Type: "+ param.getContentType() + CRLF + CRLF;
return header.getBytes();
}
//for sending image and data//
=========================
try {
String urlToSend = url;
connection = (HttpConnection)Connector.open(urlToSend, Connector.READ_WRITE, true);
connection.setRequestMethod(HttpConnection.POST);
connection.setRequestProperty("Content-Type", MULTIPART_CONTENT_TYPE);
connection.setRequestProperty("Content-Length", String.valueOf(bytes.length));
outputStream = connection.openOutputStream();
int offset = 0;
int chunk = DATA_CHUNK_SIZE;
int len = bytes.length;
while (offset < len) {
if (offset + chunk >= len) {
chunk = len - offset;
}
outputStream.write(bytes, offset, chunk);
offset += chunk;
}
return getResponseAsSting(connection);
} finally {
safelyCloseStream(outputStream);
safelyCloseStream(connection);
if (bytes != null) {
bytes = null; // notify VM it can safely free the RAM
}
}
//for getting the result//
===================
private static String getResponseAsSting(HttpConnection conn) throws IOException {
String result = "";
InputStream inputStream = null;
try {
inputStream = conn.openInputStream();
int len;
byte[] data = new byte[512];
do {
len = inputStream.read(data);
if(len > 0){
result += new String(data, 0, len);
}
} while(len > 0);
} catch (Exception e) {
if (e instanceof IOException) {
throw (IOException)e;
}
} finally {
safelyCloseStream(inputStream);
}
return result;
}
