apache.commons.net.ftp.FTPClient沒有將文件上傳到所需文件夾

Question

我使用以下代碼將xml文件上載到服務器中的目錄/ home/domainname/public_html/guest。但是，該文件僅上傳到位置/ home/domainname。它不會上傳到子目錄。請指教。

FTPClient client = new FTPClient（）; FileInputStream fis = null;

try { 
     client.connect(Util.getProductsXMLFTPServer()); 
     client.login(Util.getProductsXMLFTPUser(), Util.getProductsXMLFTPPassword()); 

     // 
     // Create an InputStream of the file to be uploaded 
     // 

     fis = new FileInputStream(new File(Util.getProductsXMLFTPInputFilePath(), Util.getProductsXMLFTPOutputFileName())); 
     client.changeWorkingDirectory(Util.getProductsXMLFTPUploadPath()); 


     client.storeFile(Util.getProductsXMLFTPOutputFileName(), fis); 
     client.logout(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } finally { 
     try { 
      if (fis != null) { 
       fis.close(); 
      } 
      client.disconnect(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    }

我檢查了你的代碼，它的工作原理。我只將文件類型聲明更改爲二進制文件，這對於XML文件可能不需要。 這裏是我完整的代碼以供參考：

package apachenet.ftp; 

import java.io.File; 
import java.io.FileInputStream; 
import java.io.IOException; 

import org.apache.commons.net.ftp.FTP; 
import org.apache.commons.net.ftp.FTPClient; 

public class App { 
    public static void main(String[] args) { 
     FTPClient client = new FTPClient(); 
     FileInputStream fis = null; 
     try { 
      client.connect(/*Util.getProductsXMLFTPServer()*/"127.0.0.1"); 
      client.login(/*Util.getProductsXMLFTPUser()*/"pwyrwinski", 
        /*Util.getProductsXMLFTPPassword()*/"secret"); 
      client.setFileType(FTP.BINARY_FILE_TYPE); // optional 
      fis = new FileInputStream(
        new File(/* Util.getProductsXMLFTPInputFilePath() */"/home/pwyrwinski", 
          /* Util.getProductsXMLFTPOutputFileName() */"img.png")); 
      client.changeWorkingDirectory(/*Util.getProductsXMLFTPUploadPath()*/ "someDir"); 


      client.storeFile(/*Util.getProductsXMLFTPOutputFileName()*/"img_bis.png", fis); 
      client.logout(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } finally { 
      try { 
       if (fis != null) { 
        fis.close(); 
       } 
       client.disconnect(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
    } 
} 

正如你可以看到它的大致一樣的你。 Util類調​​用被替換爲原始數據。

當我運行它時，文件/home/pwyrwinski/img.png上傳到ftp服務器上的{FTP_USER_ROOT}/someDir目錄，名稱更改爲img_bis.png。我認爲這正是你想達到的目標。

讓我們回到你的問題。

1. 嘗試檢查從 Util.getProductsXMLFTPUploadPath()返回的內容。我的猜測並不是你期待的 - 所以在你的IDE中進行調試或者打印到控制檯。
2. 檢查從Util.getProductsXMLFTPUploadPath()返回的路徑 調用以斜槓開始，它不應該。

更新1. 是否豬病/home/domainname/public_html/guest服務器上存在嗎？

添加下面的方法到類：

private static void showServerReply(FTPClient ftpClient) { 
    String[] replies = ftpClient.getReplyStrings(); 
    if (replies != null && replies.length > 0) { 
     for (String aReply : replies) { 
      System.out.println("SERVER: " + aReply); 
     } 
    } 
} 

後每 FTP客戶端的方法調用調用它。這將爲您提供每個命令結果的代碼和說明。我懷疑client.changeWorkingDirectory(...)以錯誤結尾，可能是：550 Permission Denied (or No such file or folder)。

下一頁修改爲：

client.login(Util.getProductsXMLFTPUser(), Util.getProductsXMLFTPPassword()); 
System.out.println(client.printWorkingDirectory()); // added this line! 

這將告訴我們什麼是在登錄後，當前的工作目錄

請發表您的結果。

FTPClient ftpClient = new FTPClient(); 
     try { 
       System.out.println("before server connection"); 
      ftpClient.connect(server, port); 
      System.out.println("before user name and passwod"); 
      ftpClient.login(user, pass); 
      ftpClient.enterLocalActiveMode(); 

      ftpClient.setFileType(FTP.BINARY_FILE_TYPE); 

      System.out.println("connection sucess"); 


      // windows working fine 
      File secondLocalFile = new File("/home/aims/archived_reports/tes_S_000000123/test.pdf"); 
//   String secondRemoteFile = "/archived_reports/PermanentRecord.pdf"; 

//linux 
      // File secondLocalFile = new File("/archived_reports/tes_S_000009123/test.pdf"); 

      String secondRemoteFile = "remotefilename.pdf"; 
      InputStream inputStream = new FileInputStream(secondLocalFile); 

      System.out.println("Start uploading second file"); 

        ftpClient.changeWorkingDirectory("/reports");// home/ftp.test/reports folder 


      System.out.println("Prasent Working Directory :"+ftpClient.printWorkingDirectory()); 


      OutputStream outputStream = ftpClient.storeFileStream(secondRemoteFile); 
       int returnCode = ftpClient.getReplyCode(); 
       System.out.println(returnCode); 
      byte[] bytesIn = new byte[4096]; 
      int read = 1; 

      while ((read = inputStream.read(bytesIn)) != -1) { 
       outputStream.write(bytesIn, 0, read); 
      } 

System.out.println();   
      inputStream.close(); 
      outputStream.close(); 
        boolean completed = ftpClient.completePendingCommand(); 
      if (completed) { 
       System.out.println("The second file is uploaded successfully."); 
      }
