Android FTP上傳 - 文件未上傳

我想通過ftp上傳文件。我發現了一些信息而已，並建立我的課就像我在這裏找到：http://www.sebastianviereck.de/ftp-upload-mit-android/Android FTP上傳 - 文件未上傳

我還添加Internet權限的清單，並設置strictmode像我在這裏找到： Error StrictMode$AndroidBlockGuardPolicy.onNetwork

的結果storeFile ist treu並且ftpClient的回覆代碼爲226（「關閉數據連接，請求的文件操作成功（例如，文件傳輸或文件中止）」）。

對我來說看起來不錯，但文件沒有上傳。

有人有想法嗎？

這裏是我的代碼：

主營：

FtpDataHandler ftp = new FtpDataHandler("serverName", "userName", "password", "/folder"); 
        ftp.uploadFile("/storage/emulated/0/pictures/test_sig.jpg", "test_sig.jpg");

FTP處理程序：

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"); 
     } 
    } 
}

這裏也是ftpClient.getReplyString（）的ftpClient.login，this.ftpClient後.changeWorkingDirectory（this.serverDirectory），this.ftpClient.setFileType（2）;

FTP Server Response: 200 Type set to I

和this.ftpClient.storeFile（remoteFileName，buffIn）之後的回覆代碼;

Reply code: 226

我可以通過Ftp客戶端（如FileZilla或Turbo FTP Client）上傳文件。在這裏你可以看到我的筆記本電腦上使用的FileZilla的日誌。

的可能的複製[無法上傳在Android的FTP服務器上的文件（https://stackoverflow.com/questions/11427346/unable-to-upload-file-on-ftp-server-in-android） –

@ DimaKozhevin這個問題不是重複的。我真的從storeFile功能回來 – Fabian

告訴我們[mcve]。向我們展示'remoteFileName'的實際值。告訴我們如何檢查*「文件未上傳」*。向我們顯示一個日誌文件。 –

予固定的問題。這是FtpDataHandler中的一個副本並且失敗。我設置this.serverDirectory等於serverAdress。所以Ftp客戶端找不到服務器上的目錄。

下面是代碼片段：

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(); 
}

我也固定在它的問題，所以它更容易找到完整的解決方案。

感謝@Martin Prikryl的支持。
