My code for uploading image to server is :
String userIdParameter = String.valueOf(userId);
String fileName = "temporary_holder.jpg";
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
String sourceFileUri = HomeScreen.get_path();
String upLoadServerUri = "http://10.120.10.87:8080/WebImage/UploadImage";
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
Log.e("Huzza", "Source File Does not exist");
return;
}
int serverResponseCode = 0;
try {
// open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
// ------------------ CLIENT REQUEST
URL url = new URL(upLoadServerUri);
// Open a HTTP connection to the URL
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
// Use a post method.
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type",
"multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("file_name", fileName);
conn.setRequestProperty("file_name_audio", fileName);
conn.setRequestProperty("X-myapp-param1", userIdParameter);
// conn.setFixedLengthStreamingMode(1024);
// conn.setChunkedStreamingMode(1);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"file_name\";filename=\""
+ fileName + "\"" + lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
int streamSize = (int) sourceFile.length();
bufferSize = streamSize / 10;
System.out.println("streamSize" + streamSize);
buffer = new byte[streamSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
int count = 0;
while (bytesRead > 0) {
progress = (int) (count);
displayNotification();
Thread.sleep(500);
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
// bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
count += 10;
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
System.out.println("Upload file to serverHTTP Response is : "
+ serverResponseMessage + ": " + serverResponseCode);
// close streams
System.out.println("Upload file to server" + fileName
+ " File is written");
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
ex.printStackTrace();
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
e.printStackTrace();
}
// this block will give the response of upload link
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(
conn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
System.out.println("RESULT Message: " + line);
}
rd.close();
} catch (IOException ioex) {
Log.e("Huzza", "error: " + ioex.getMessage(), ioex);
}
return; // like 200 (Ok)
Uploading image to server works fine. I need to upload both mp3 file and image to the server.
