This is my code to send file to server over HTTP,
but i am trying to transfer using HTTPS i tried it for passing values using parameters it was working but i don't know how to code it with file stream,
can anybody help me with this i have ssl certificate

I'm experienced with PHP, JavaScript and a lot of other scripting languages, but I don't have a lot of experience with Java or Android.
I'm using below code to send file to sever, that is run without any problem, but I want to POST other data like "operation=upload_file" with file.
FileInputStream fileInputStream = new FileInputStream(selectedFile);
URL url = new URL(SERVER_URL);
connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);//Allow Inputs
connection.setDoOutput(true);//Allow Outputs
connection.setUseCaches(false);//Don't use a cached Copy
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("ENCTYPE", "multipart/form-data");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
//creating new dataoutputstream
dataOutputStream = new DataOutputStream(connection.getOutputStream());
//writing bytes to data outputstream
dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
+ selectedFilePath + "\"" + lineEnd);
dataOutputStream.writeBytes(lineEnd);
//returns no. of bytes present in fileInputStream
bytesAvailable = fileInputStream.available();
//selecting the buffer size as minimum of available bytes or 1 MB
bufferSize = Math.min(bytesAvailable,maxBufferSize);
//setting the buffer as byte array of size of bufferSize
buffer = new byte[bufferSize];
//reads bytes from FileInputStream(from 0th index of buffer to buffersize)
bytesRead = fileInputStream.read(buffer,0,bufferSize);
//loop repeats till bytesRead = -1, i.e., no bytes are left to read
while (bytesRead > 0){
//write the bytes read from inputstream
dataOutputStream.write(buffer,0,bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable,maxBufferSize);
bytesRead = fileInputStream.read(buffer,0,bufferSize);
}
dataOutputStream.writeBytes(lineEnd);
dataOutputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
serverResponseCode = connection.getResponseCode();
String serverResponseMessage = connection.getResponseMessage();
Log.i(TAG, "Server Response is: " + serverResponseMessage + ": " + serverResponseCode);
//response code of 200 indicates the server status OK
if(serverResponseCode == 200){
runOnUiThread(new Runnable() {
#Override
public void run() {
tvFileName.setText("File Upload completed.\n\n You can see the uploaded file here: \n\n" + "http://coderefer.com/extras/uploads/"+ fileName);
}
});
}
//closing the input and output streams
fileInputStream.close();
dataOutputStream.flush();

int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
String responseFromServer = "";
String urlString = BASE_URL + "upload.php";
try {
//------------------ CLIENT REQUEST
FileInputStream fileInputStream = new FileInputStream(new File(filePath));

dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + filePath + "\"" + 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...

} catch (MalformedURLException ex) {

i have a problem and it is with encoding Strings.
some of my strings are in persian and when send to server they get changet to other characters like below:
,3ED3ED3~'3E'3ED4
or
*G1'F
How can i send params correctlly?
Find the appropriate encoding for the server, and encode your request with that encoding, and decode the response with that encoding too. For example, the code I did write yesterday on Python:
params = urllib.parse.urlencode({'tool': tool, 'input': full_text, 'token': token}).encode("UTF-8") # Encoding parameters
result = urllib.request.urlopen(api_url, params) # Making request
readed_result = result.read().decode("UTF-8") # Decoding response
The logic is the same in the Java too.
How to find appropriate encoding for server? Check http header for encoding.
For example:
public String uploadFile(String sourceFileUri) {
fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
return "";
}
else
{
try {
// open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL urls = new URL(url_upload);
conn = (HttpURLConnection) urls.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setChunkedStreamingMode(1024);
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("fileName", fileName);
String cookie=AppController.getInstance().getPrefManger().getCookie();
Log.i("hello","cookie"+cookie);
conn.setRequestProperty("Cookie", cookie);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"albumId\"" + lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes(selectedAlbumId); // mobile_no is String variable
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"caption\"" + lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes(caption.getText().toString()); // mobile_no is String variable
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=files;fileName="

I really confuse about this , Is my code wrong?
I need help.
Thanks in advance.
it solved , u can see my code in here
