Вам не нужно разделять входной или выходной поток.
Вы можете загрузить большой файл с составной сущностью. В составной сущности есть класс FileEntity, который отвечает за загрузку файла
У меня есть код для составного объекта, см. Код ниже.
public class uploadFile extends AsyncTask<Void, Void, Boolean> {
private final ProgressDialog dialog = new ProgressDialog(parentActivity);
protected void onPreExecute() {
this.dialog.setMessage("Uploading file");
this.dialog.setCancelable(false);
this.dialog.show();
}
@Override
protected Boolean doInBackground(Void... arg0) {
try {
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(URLS.PRESCRIPTION_POST_URL);
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("title", new StringBody("This is a title of video file"));
try {
File f = new File(Environment.getExternalStorageDirectory(), "your file name with extension");
FileBody body = new FileBody(f);
reqEntity.addPart("parameter that server will read", body);
} catch (Exception e) {
reqEntity.addPart("parameter that server will read", new StringBody(""));
}
reqEntity.addPart("description", new StringBody("description"));
postRequest.setEntity(reqEntity);
HttpResponse response = httpClient.execute(postRequest);
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String sResponse; StringBuilder s = new StringBuilder();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
Log.v("Response for POst", s.toString());
return true;
} catch (Exception e) {
Log.e("MyPharmacyOptions", "Error :: " + e);
}
return false;
}
@Override
protected void onPostExecute(Boolean result) {
if (this.dialog.isShowing()) {
this.dialog.dismiss();
}
if (result) {
Toast.makeText(parentActivity,
"File uploaded successfully", Toast.LENGTH_LONG)
.show();
} else {
Toast.makeText(parentActivity, "Your Request not complete",
Toast.LENGTH_LONG).show();
}
}
}
Для использования MultipartEntity вам потребуется файл jar httpmime-4.1.2.jar
.
Есть и другая альтернатива этому
HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inputStream = null;
String pathToOurFile = "/sdcard/file_to_send.mp3"; //complete path of file from your android device
String urlServer = "URL of your server";// complete path of server
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
try
{
FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile) );
URL url = new URL(urlServer);
connection = (HttpURLConnection) url.openConnection();
// Allow Inputs & Outputs
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
// Enable POST method
connection.setRequestMethod("POST");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
outputStream = new DataOutputStream( connection.getOutputStream() );
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
outputStream.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
byte []buffer = new byte[4096];
int read = 0;
while ( (read = fileInputStream.read(buffer)) != -1 ) {
outputStream.write(buffer, 0, read);
}
outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = connection.getResponseCode();
serverResponseMessage = connection.getResponseMessage();
fileInputStream.close();
outputStream.flush();
outputStream.close();
}
catch (Exception ex)
{
//Exception handling
}
