I'm developing an application that can upload data to web server. But I don't know what I'm going to put on my content-length. I tried to get the size of my file and the other text-data that I'm going to upload but it's not correct. Can anyone know what should I gonna put on my content-length?
for (chunkId = 0; chunkId < chunks; chunkId++) {
URL url = new URL(urlString);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(20000 /* milliseconds */);
conn.setConnectTimeout(20000 /* milliseconds */);
// Allow Inputs
conn.setDoInput(true);
// Allow Outputs
conn.setDoOutput(true);
// Don't use a cached copy.
conn.setUseCaches(false);
// Use a post method.
conn.setRequestMethod("POST");
String encoded = Base64.encodeToString((_username+":"+_password).getBytes(),Base64.NO_WRAP);
conn.setRequestProperty("Authorization", "Basic "+encoded);
conn.setRequestProperty("Connection", "Keep-Alive");
//conn.setChunkedStreamingMode(mychunkSize);
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
conn.setRequestProperty("Content-Length", "**I don't know what I'm going to put here**");
conn.connect();
dos = new DataOutputStream( conn.getOutputStream() );
//dos.writeBytes("Content-Length: " + String.valueOf(size) + lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
// Send parameter #file
dos.writeBytes("Content-Disposition: form-data; name=\"fieldNameHere\";filename=\"" + mFile.getName() + "\"" + lineEnd); // filename is the Name of the File to be uploaded
dos.writeBytes("Content-Type: image/jpeg" + lineEnd);
dos.writeBytes(lineEnd);
// Send parameter #chunks
dos.writeBytes("Content-Disposition: form-data; name=\"chunk\"" + lineEnd);
dos.writeBytes(param2 + lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
// Send parameter #name
dos.writeBytes("Content-Disposition: form-data; name=\"name\"" + lineEnd);
dos.writeBytes(param3 + lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
bytesAvailable = stream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = stream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = stream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = stream.read(buffer, 0, bufferSize);
Log.i("BytesAvailable", String.valueOf(bytesAvailable));
Log.i("bufferSize", String.valueOf(bufferSize));
Log.i("buffer", String.valueOf(buffer));
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// close streams
stream.close();
dos.flush();
dos.close();
}
} catch (MalformedURLException ex) {
System.out.println("From CLIENT REQUEST:" + ex);
}catch (IOException ioe) {
System.out.println("From CLIENT REQUEST:" + ioe);
}catch (Exception e) {
Log.e("From CLIENT REQUEST:", e.toString());
}
