Can't get JSOn Response when I POST to

I'm using Java HttpURLConnection to send a POST request to https://www.arcgis.com/sharing/generateToken with the parameters username, password, f, expiration, referer.

 

I need to get back the JSON response to extract the Token  and store in my object, but the result I get seemingly is an HTML Page.

This is what I' sing, I simplified the code to keep my question clean

DataOutputStream wr = new DataOutputStream(httpConnection.getOutputStream());
wr.write(bytesArray);
wr.flush();
wr.close();

InputStream in = httpConnection.getInputStream();
Reader reader = new BufferedReader(new InputStreamReader(in, "UTF-8"));
StringBuilder content = new StringBuilder();
char[] buffer = new char[5000];
int n;
while ( ( n = reader.read(buffer)) != -1 ) {
    content.append(buffer, 0, n);
}
reader.close();
return content.toString();

 

Initial Params string: username=<correct username>&passowrd=<correct password>&f=json&expiration=60&referer=http%3Aww.arcgis.com
Data Bytes: [B@7506e922Sending POST request to URL : https://www.arcgis.com/sharing/generateToken

This is the response I get back.
