Not really doing work in Java (so there may be better ways of doing it) but I did encounter similar issue when working on a blog post on same topic. This is how I found out error details:
Assuming con
is your HttpsURLConnection
object:
int responseCode = con.getResponseCode();
InputStream errorStream = con.getErrorStream();//Get the error stream
if (errorStream != null) {//Read the detailed error message from the stream
String detailedErrorMessage = getStringFromInputStream(errorStream);
System.out.println(detailedErrorMessage);
}
and here's the implementation of getStringFromInputStream
method:
// Source - http://www.mkyong.com/java/how-to-convert-inputstream-to-string-in-java/
private static String getStringFromInputStream(InputStream is) {
BufferedReader br = null;
StringBuilder sb = new StringBuilder();
String line;
try {
br = new BufferedReader(new InputStreamReader(is));
while ((line = br.readLine()) != null) {
sb.append(line);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (br != null) {
try {
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return sb.toString();
}
Here's a generic post method I wrote:
private static int processPostRequest(URL url, byte[] data, String contentType, String keyStore, String keyStorePassword) throws UnrecoverableKeyException, KeyManagementException, KeyStoreException, NoSuchAlgorithmException, IOException, ProtocolException {
SSLSocketFactory sslFactory = getSSLSocketFactory(keyStore, keyStorePassword);
HttpsURLConnection con = null;
con = (HttpsURLConnection) url.openConnection();
con.setSSLSocketFactory(sslFactory);
con.setDoOutput(true);
con.setRequestMethod("POST");
con.addRequestProperty("x-ms-version", "2013-08-01");
con.setRequestProperty("Content-Length", String.valueOf(data.length));
con.setRequestProperty("Content-Type", contentType);
DataOutputStream requestStream = new DataOutputStream (con.getOutputStream());
requestStream.write(data);
requestStream.flush();
requestStream.close();
int responseCode = con.getResponseCode();
InputStream errorStream = con.getErrorStream();
if (errorStream != null) {
String detailedErrorMessage = getStringFromInputStream(errorStream);
System.out.println(detailedErrorMessage);
}
return responseCode;
}
