Android FTP загрузка - файлы не загружены
Я хочу загрузить файл через ftp. Я нашел некоторую информацию об этом и построил свой класс, как я нашел это здесь: http://www.sebastianviereck.de/ftp-upload-mit-android/
Я также добавил интернет-разрешение в манифест и установил строгий режим, как нашел его здесь: Ошибка StrictMode$AndroidBlockGuardPolicy.onNetwork
Результат storeFile ist treu и код ответа ftpClient - 226 ( "Закрытие подключения к данным. Требуемое действие файла успешно (например, передача файла или прерывание файла)").
Так что это выглядит хорошо для меня, но файлы не загружены.
У кого-то есть идея?
Вот мой код:
Главный:
FtpDataHandler ftp = new FtpDataHandler("serverName", "userName", "password", "/folder");
ftp.uploadFile("/storage/emulated/0/pictures/test_sig.jpg", "test_sig.jpg");
FTP-обработчик:
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import org.apache.commons.net.ftp.FTPClient;
import android.util.Log;
public class FtpDataHandler {
private static final String TAG = "FtpDataHandler";
String serverAdress;
String userName;
String password;
String serverDirectory;
FTPClient ftpClient;
public FtpDataHandler(String serverAdress, String userName, String password, String serverDiretory) {
this.serverAdress = serverAdress;
this.userName = userName;
this.password = password;
//this was my problem. I set the serverAdress to the serverDirectory insted the serverDirectory
//this.serverDirectory = serverAdress;
this.serverDirectory = serverDirectory;
connect();
}
public String getServerAdress() {
return serverAdress;
}
public String getUserName() {
return userName;
}
public String getServerDirectory() {
return serverDirectory;
}
public boolean uploadFile(String localFilePath, String remoteFileName) {
boolean result = false;
BufferedInputStream buffIn = null;
try {
buffIn = new BufferedInputStream(new FileInputStream(localFilePath));
} catch (FileNotFoundException e) {
Log.d(TAG,
"FileNotFoundException: local File to be uploaded not Found: " + localFilePath);
}
ftpClient.enterLocalPassiveMode();
try {
result = ftpClient.storeFile(remoteFileName, buffIn);
Log.d(TAG, "Reply code: " + ftpClient.getReplyCode());
} catch (IOException e) {
Log.d(TAG, "IOException: remote File could not be accessed");
}
try {
buffIn.close();
} catch (IOException e) {
Log.d(TAG, "IOException: buffIn.close()");
}
return result;
}
public boolean connect(){
boolean bool = false;
ftpClient = new FTPClient();
try {
ftpClient.connect(this.serverAdress);
bool = ftpClient.login(this.userName, this.password);
if (!bool){
Log.d(TAG, "Login Reply Code" + ftpClient.getReplyCode());
}
ftpClient.changeWorkingDirectory(this.serverDirectory);
ftpClient.setFileType(org.apache.commons.net.ftp.FTP.BINARY_FILE_TYPE);
} catch (IOException e) {
Log.d(TAG,
"IOException ftp Client could not be established.controll Login, Server, Pw.");
}
Log.d(TAG, "FTP Server Response: " + ftpClient.getReplyString());
return bool;
}
public void unregisterConnection(){
try {
ftpClient.logout();
ftpClient.disconnect();
} catch (IOException e) {
Log.d(TAG, "IOException: ftpClient close/logout");
}
}
}
Здесь также есть ftpClient.getReplyString() после ftpClient.login, this.ftpClient.changeWorkingDirectory(this.serverDirectory), this.ftpClient.setFileType(2);
FTP Server Response: 200 Type set to I
И код ответа после this.ftpClient.storeFile(remoteFileName, buffIn);
Reply code: 226
Я могу загрузить файл через FTP-клиент, такой как FileZilla или Turbo FTP Client. Здесь вы можете увидеть журнал FileZilla, используемый на моем ноутбуке.

Решение
Я исправил проблему. Это была копия и прошлая ошибка в FtpDataHandler. Я установил this.serverDirectory равным serverAdress. Таким образом, Ftp Client не может найти каталог на сервере.
Вот фрагмент кода:
public FtpDataHandler(String serverAdress, String userName, String password, String serverDiretory) {
this.serverAdress = serverAdress;
this.userName = userName;
this.password = password;
//this was my problem. I set the serverAdress to the serverDirectory insted the serverDirectory
//this.serverDirectory = serverAdress;
this.serverDirectory = serverDirectory;
connect();
}
Я также исправил это в вопросе, чтобы было легче найти полное решение.
Спасибо @Martin Prikryl за поддержку.
