I have many images in a folder, and I want to upload this files, in that folder, to a php server, in java using httpurlconnection.
Until now, I made it but just with one photo, like the code I show you down.

// might not need to specify the content-length when sending chunked

lig.setRequestProperty("Content-Length", String.valueOf((message1
.length() + message2.length() + imgData.length)));
System.out.println("open os");
os = lig.getOutputStream();
System.out.println(message1);

// SEND THE IMAGE
int index = 0;
int size = 1024;
do {
System.out.println("write:" + index);
if ((index + size) > imgData.length) {

}
os.write(imgData, index, size);
index += size;
} while (index < imgData.length);
System.out.println("written:" + index);
System.out.println(message2);
os.write(message2.getBytes());
os.flush();
System.out.println("open is");
is = lig.getInputStream();
char buff = 512;
int len;
byte[] data = new byte[buff];
do {
System.out.println("READ");
len = is.read(data);
if (len > 0) {
System.out.println(new String(data, 0, len));
}
} while (len > 0);
System.out.println("DONE");
}catch(Exception e){
e.printStackTrace();
}finally {
System.out.println("Close connection");
try {
os.close();
} catch (Exception e) {
}
try {
is.close();
} catch (Exception e) {
}
try {
} catch (Exception e) {

}
}
}
But I want send all photos in that folder
if you can, show me the code in php too please.

We have to connect to a asp.net server to download media items.
We've got this code:
URLConnection urlConnection;
try {
String localTempPath = SettingsManager.getInstance().getLocalTempMediaItemFilePath(loadingItem);
URL serverPath = new URL(SettingsManager.getInstance().getServerMediaItemFilePath(loadingItem));
urlConnection = serverPath.openConnection();
String urlParameters = "http://tempuri.org/";
HttpURLConnection connection = (HttpURLConnection) serverPath.openConnection();
connection.setFollowRedirects(true);
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("GET");
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
for (String cookie:cookies.keySet()) {
connection.setRequestProperty("Cookie", cookie + "=" + cookies.get(cookie));
} //only one Cookie: ASPNET_SessionId=...
connection.connect();
int response = connection.getResponseCode();
File f = new File (localTempPath);
f.createNewFile();
if (f.exists()){
FileOutputStream fileOutput = new FileOutputStream(f);
//Get Response
InputStream is = connection.getInputStream();
int totalsize = connection.getContentLength();
int downloadedSize = 0;
byte[] buffer = new byte [1024];
int bufferLength = 0;
while ((bufferLength = is.read(buffer)) > 0){
fileOutput.write(buffer,0,bufferLength);
downloadedSize += bufferLength;
}
fileOutput.close();
}
return null;
} catch (Exception e) {
e.printStackTrace();
return null;
} finally {
}
We have to send the Session-Cookie to the server but we always get a 404:java.io.FileNotFoundException: http://possuite.emmgt.at/v30/dataservice/MediaItem/6629.mi
I have following code, it downloads the file, but Adobe says that the file is damage. The file is 74KB big, but I can only download about 27KB. Can you tell me what's wrong. Thanks

I want to upload an audio file into server.
I am able upload audio file to server through above code but the file is not working(not playing in system). If u have any idea please help me.
You should be using neither FileReader nor StringBuilder here as it treats the data as characters (encoded according to the default system character set). Really, you should not be using a Reader at all. Binary data should be handled via InputStream, e.g.
final ByteArrayOutputStream out = new ByteArrayOutputStream();
try (final InputStream in = new FileInputStream(file)) {
final byte[] buf = new byte[2048];
int n;
while ((n = in.read(buf)) >= 0) {
out.write(buf, 0, n);
}
}
final byte[] data = out.toByteArray();
Did you check checksum on server? Is it arriving unmodified?
If not, try other method to post files. This one helped me a lot:
/**
* Post request (upload files)
* #param sUrl
* #param params Form data
* #param files
* #return
*/
public static HttpData post(String sUrl, Hashtable<String, String> params, ArrayList<File> files) {
HttpData ret = new HttpData();
try {
String boundary = "*****************************************";
String newLine = "rn";
int bytesAvailable;
int bufferSize;
int maxBufferSize = 4096;
int bytesRead;
URL url = new URL(sUrl);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setDoInput(true);

//dos.writeChars(params);
//upload files
for (int i=0; i<files.size(); i++) {
Log.i("HREQ", i+"");

dos.writeBytes("--" + boundary + newLine);

I think , you must call "dos.flush()" method. My code runs perfectly, postContent is string buffer and contanins 300KB string.
if (getPostContent() == null) {
httpConnection.setRequestMethod(HttpConnection.GET);
} else {
String type = "application/x-www-form-urlencoded";
byte[] bytes = postContent.toString().getBytes("UTF-8");
httpConnection.setRequestProperty("Content-Type", type);
httpConnection.setRequestProperty("Content-Length", bytes.length + "");
httpConnection.setRequestMethod(HttpConnection.POST); //setupPost method for this conn
DataOutputStream dos = new DataOutputStream(httpConnection.openOutputStream());
dos.write(bytes);
dos.flush();
dos.close();
}
