Problems using HttpUrlconnection to do login and upload an image

I've made an API which has an authorization part and a body part. The body part is for users to upload an image. For the basic auth part, it just need the username and the password. For the uploading part, it needs two parameters and an jpeg image file. I just got from some resources for uploading file but not combining the login part, so I modify it myself, but I don't know what's wrong in my code, it doesn't work. The following is my code:
public String multipartRequest(String urlTo, Map<String, String> parmas, String filepath, String filefield, String fileMimeType) throws CustomException {
HttpsURLConnection connection = null;
DataOutputStream outputStream = null;
InputStream inputStream = null;
String twoHyphens = "--";
String boundary = "*****" + Long.toString(System.currentTimeMillis()) + "*****";
String lineEnd = "\r\n";
String result = "";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
String[] q = filepath.split("/");
int idx = q.length - 1;
try {
File file = new File(filepath);
FileInputStream fileInputStream = new FileInputStream(file);
URL url = new URL(urlTo);
connection = (HttpsURLConnection) url.openConnection();
///// certification
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
SSLSocketFactory newFactory = sc.getSocketFactory();
connection.setSSLSocketFactory(newFactory);
connection.setHostnameVerifier(new HostnameVerifier() {
#Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
String a = username + ":" + password;
byte[] data = a.getBytes();
String info = "Basic " + Base64.encodeToString(data, Base64.DEFAULT);
connection.setRequestProperty("Authorization", info);
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Content-Type", "text/plain");
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("User-Agent", "Android Multipart HTTP Client 1.0");
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
outputStream = new DataOutputStream(connection.getOutputStream());
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"" + filefield + "\"; filename=\"" + q[idx] + "\"" + lineEnd);
outputStream.writeBytes("Content-Type: " + fileMimeType + lineEnd);
outputStream.writeBytes("Content-Transfer-Encoding: binary" + lineEnd);
outputStream.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
outputStream.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
outputStream.writeBytes(lineEnd);
// Upload POST Data
Iterator<String> keys = parmas.keySet().iterator();
while (keys.hasNext()) {
String key = keys.next();
String value = parmas.get(key);
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"" + key + "\"" + lineEnd);
outputStream.writeBytes("Content-Type: text/plain" + lineEnd);
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(value);
outputStream.writeBytes(lineEnd);
}
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
inputStream = connection.getInputStream();
result = this.convertStreamToString(inputStream);
fileInputStream.close();
inputStream.close();
outputStream.flush();
outputStream.close();
return result;
} catch (Exception e) {
throw new CustomException("error e");
}
}
private String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
I don't know why it doesn't work.
Does anyone know how to use httpurlconnection to do both login and uploading files? In my code, I add both the following lines, is this a problem? I mean use "Content-Type" for multiple times(Login and Uploading files):
For Login part:
connection.setRequestProperty("Content-Type", "text/plain");
For uploading file part:
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
But I call them at the same time(same function), is this a problem?

Uploading file to server NOT WORKING

My code is below.
After uploading (time is varying for different file sizes) I got 200 Ok and response
public class CloudFileUploader extends AsyncTask<String, Void, String> {
#Override

String contentLength=Long.toString(mFile.length());
// conn.setRequestProperty("Content-Length",contentLength );
AppSharedPreference mPref = new AppSharedPreference(mContext);

dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"myFile\";filename=\"" + mFile.getName() + "\"" + lineEnd);
dos.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
Log.i(TAG, "Initial .available : " + bytesAvailable);
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
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);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
serverResponseCode = conn.getResponseCode();
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException | FileNotFoundException | ProtocolException ex) {

} catch (IOException e) {

}
if (serverResponseCode == 200) {
StringBuilder sb = new StringBuilder();
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(conn
.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
sb.append(line);
}
rd.close();
} catch (IOException ex) {
ex.printStackTrace();
if (onFileUploadListener != null) {
onFileUploadListener.onUploadFailed(mMessage, new AppError(ErrorHandler.ERROR_FROM_SERVER, ErrorHandler.ErrorMessage.ERROR_FROM_SERVER));
}
}
return sb.toString();
} else {
return "Could not upload";
}
}
}
I put conn.setRequestProperty("Content-Length",contentLength ); but it will throw java.net.ProtocolException.
I tested differnt code but the issue is still there.
Below given is my php server script.
$status['apiId'] = _GROUP_FILE_UPLOAD_API;
$user_id = $this->user['user_id'];
$target_dir = ROOTDIR_PATH . DS . "data" . DS . "GroupFileUploads" . DS;
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$fileUpload = NULL;
if ($this->headers->get('groupId')) {
$fileUpload['groupId'] = $groupId = $this->headers->get('groupId')->getFieldValue();
}
if ($this->headers->get('messageType')) {
$fileUpload['messageType'] = $messageType = $this->headers->get('messageType')->getFieldValue();
} if ($this->headers->get('message')) {
$fileUpload['message'] = $message = $this->headers->get('message')->getFieldValue();
}
if ($this->headers->get('senderName')) {
$fileUpload['senderName'] = $senderName = $this->headers->get('senderName')->getFieldValue();
}
The code is not working. It is not saving anything to the folder I given.
But It is working from Postman and AdvancedRestClient
When I put die() then i Got
Array( [myFile] => Array ( [name] => 1495018448FaceApp_1494992050886.jpg [type] => [tmp_name] => /tmp/phpH2kH47 [error] => 0 [size] => 917953 ))
The [type] => should be image/jpg but it is empty

Android: Why am I unable to upload an image to a web server?

I'm using HttpUrlConnection to upload an image to a web server. When I run the app and attempt to upload an image I get a Http response 200 as well as receive the filename and the imageid of the supposed image that has been uploaded, but when i check the server the image was not uploaded. The filename and the id are now part of the list but when I attempt to retrieve the image it returns null.
public String uploadFile(String apiPath, String filePath, String type)
{
String path = "";
String result = "";
switch (type)
{
case "M":
path = "Merchant/" + apiPath;
break;
case "C":
path = "Customer/" + apiPath;
break;
}
Log.i(ApiSecurityManager.class.getSimpleName(), m_token);
String href = "http://tysomapi.fr3dom.net/" + path + "?token=" + m_token;
Log.i(ApiSecurityManager.class.getSimpleName(), href);
try
{
String myIp = getIp();
URL url = new URL(href);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("User-Agent", "java");
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type", "multipart/form-data; boundary = " + boundary);
conn.setRequestProperty("X-Forwarded-For", myIp);
conn.setDoOutput(true);
File file = new File(filePath);
DataOutputStream ds = new DataOutputStream(conn.getOutputStream());
ds.writeBytes(twoHyphens + boundary + LINE_FEED);
ds.writeBytes("Content-Disposition: form-data; name=\"image\"; filename=\"" + file.getName() + "\"" + LINE_FEED);
ds.writeBytes("ContentType: image/peg" + LINE_FEED);
ds.writeBytes(twoHyphens + boundary + LINE_FEED);
FileInputStream fStream = new FileInputStream(file);
int bytesAvailable = fStream.available();
int maxBufferSize = 1024;
int bufferSize = Math.min(bytesAvailable, maxBufferSize);
byte[] buffer = new byte[bufferSize];
int bytesRead = fStream.read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
ds.write(buffer, 0, bufferSize);
bytesAvailable = fStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fStream.read(buffer, 0, bufferSize);
}
ds.writeBytes(LINE_FEED);
ds.writeBytes(twoHyphens + boundary + twoHyphens + LINE_FEED);
fStream.close();
ds.flush();
ds.close();
Log.i(getClass().getSimpleName(), "Response Code: " + conn.getResponseCode());
if (conn.getResponseCode() != HttpURLConnection.HTTP_OK)
{
throw new RuntimeException("Failed : HTTP error code : "
+ conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
String output;
while ((output = br.readLine()) != null)
{
result = result + output;
}
conn.disconnect();
}
catch (
MalformedURLException e
)
{
e.printStackTrace();
}
catch (
IOException e
)
{
e.printStackTrace();
}
return result;
}

I was able to fix the problem by using PrintWriter and OutputStream instead of DataOutputStream to pass the headers and the image.

Uploading large files from android app to server using Perl

I need to upload videos from my android app to my website.
I use an async task and a method (included here below) to send the video, but I do not know how to set up the Perl scrip on my site that would interact with the app.
By now any test perl script (with any chmod combination) I use as a targetURL returns:
03-30 17:09:06.771: I/Server Response Code(21092): 403
03-30 17:09:06.771: I/Server Response Message(21092): Forbidden
I would greatly appreciate any general direction on how to make the Perl script and what permissions to give it.
I looked around the Internet for example, but there are few and in PHP, and I need it in Perl.

Here is a example of server side code is written in Php. What it should be in Perl?
<?php

/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
echo "filename: " . basename( $_FILES['uploadedfile']['name']);
echo "target_path: " .$target_path;
}
?>
