问题
I uploading zip file using chunk method. After some iteration completed in while loop TotalParts variable automatically changed to some value. When connected to debugger its works fine for some time, but when disconnected again value changed for some files. But, after some iteration finally it will upload.Value is changing in Jsonbody in http service.
Actually TotalParts variable is final and also not declared inside while loop, although its changing to some value.
public Boolean uploadFile(String filePath,int chunkSize,JSONObject jsonObj)
{
boolean dataUploaded=false;
InputStream inStream=null;
try
{
File zipFile = new File(filePath);
int fileSize = (int)zipFile.length();
inStream = new BufferedInputStream( new FileInputStream(filePath));
final int totalparts =(int) Math.ceil((double)fileSize / (double)chunkSize);
Logger.i("outside loop- file size", String.valueOf(fileSize));
Logger.i("outside loop- chunk Size", String.valueOf(chunkSize));
Logger.i("outside loop- file totalparts", String.valueOf(totalparts));
System.out.println(totalparts);
byte [] data = new byte[chunkSize];
int index=0,checkCount=0;
boolean readNextData=true;
while ( true )
{
if(readNextData) {
inStream.read(data, 0, chunkSize);
checkCount=0;
++index;
}
if(totalparts > 200){
break;
}
Logger.i("before upload chunkList index", String.valueOf(index));
Logger.i("before upload file totalparts", String.valueOf(totalparts));
System.out.println(totalparts);
jsonObj.put("fileName", zipFile.getName());
jsonObj.put("base64Content", convertToBase64EncodingFromByteArray(data));
jsonObj.put("partNo", index);
jsonObj.put("totalParts", totalparts);
//jsonObj.put("md5checksum","A0A0");
jsonObj.put("md5checksum",CheckSum.getMd5OfByteArray(data));
String responseData = sendData(jsonObj.toString());
Logger.v("responseData",responseData);
JSONObject responData=new JSONObject(responseData);
String errorCode=(String) responData.get("ErrorCode");
if(!errorCode.equals("0"))
{
checkCount++;
readNextData=false;
if(checkCount>4)
break;
} else if(errorCode.equals("0"))
{
readNextData=true;
if( index==totalparts ){
dataUploaded=true;
break;
}
}else
{
break;
}
// status = fileUpload(chunkList.get(i), "videoChunk" + "/" + chunkList.get(i).split("/")[4]);
Logger.i("after upload chunkList index status",String.valueOf(index) );
Logger.i("after upload file totalparts", String.valueOf(totalparts));
System.out.println(totalparts);
}
}catch(Exception e){
Logger.ex(e);
}finally {
if(inStream!=null)
{
try {
inStream.close();
}catch (Exception e)
{
Logger.ex(e);
}
}
}
return dataUploaded;
}
Please check below log files about value of TotalParts-

when calling service only its changing value in jsonbody-
JSONObject object = new JSONObject(jsonbody);
//here its value changed
System.out.println("jsonbody before response totalparts-"+object.getString("totalParts"));
//normal http connection
HttpURLConnection conn = null;
// 2. open the HTTP connection
conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
// 3.2 Sets the flag indicating this connection does not use cache
conn.setUseCaches(false);
// 3.3 Sets the length of the body
conn.setDoInput(true);
// 3.4 Sets the method to POST
conn.setRequestMethod("POST");
// 3.5 Sets Content-Type
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Accept", "application/json");
OutputStream outputStream = conn.getOutputStream();
try {
try {
outputStream.write(jsonbody.toString().getBytes("UTF-8"));
outputStream.close();
} catch (Exception e) {
Logger.ex(e);
EvidensFramework.mErrorLogger.writeLog(null, this.getClass().getSimpleName()
+ ": getResponse", e.getStackTrace().toString(), "Error");
return "";
}
// handle the response
int status = conn.getResponseCode();
if (status != 200) {
InputStream is = conn.getErrorStream();
Logger.d("", "");
throw new IOException("Connection failed with error code " + status);
}
// Get Response
InputStream is = conn.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
String line;
StringBuffer response = new StringBuffer();
while ((line = rd.readLine()) != null) {
response.append(line);
response.append('\n');
}
System.out.println("jsonbody after response totalparts-"+object.getString("totalParts"));
resp = response.toString();
rd.close();
plz give any suggestion or solution for this
