对等方重置连接：ftp 期间出现套接字写入错误

Question

在尝试 ftp（使用隐式 ssl）将文件发送到服务器时，我始终收到 'Connection Reset By Peer: Socket Write Error' 或异常的 'Connection Aborted By Software' 错误。该文件已上传到服务器，但完全是空的。但是，在设置本地测试 ftp 服务器后，我可以毫无问题地将文件上传到该服务器。这些错误可能是由某种类型的防火墙引起的吗？如果不是，是否还有其他问题。如果是，是否可以更改代码中的任何内容来修复它？

使用 Apache Commons：

String SFTPHOST = compParam.getSftpHostNme();
int SFTPPORT = 990;
String SFTPUSER = compParam.getSftpLogin();
String SFTPPASS = compParam.getSftpPassword();
            FTPSClient ftpClient = new FTPSClient(true);
    try {

        ftpClient.connect(SFTPHOST, SFTPPORT);
        if(!ftpClient.login(SFTPUSER, SFTPPASS)){
            SwingUtils.showMessage(this, "Error: Trouble Connecting \n" + "User Name and Password or Host is incorrect \n"
                    + "or someone else is using these credentials");
            return;
        }
        ftpClient.enterLocalPassiveMode();
        ftpClient.setFileType(FTP.ASCII_FILE_TYPE);

        File f = new File(TLCTripRecordExportDlg.filePath + TLCTripRecordExportDlg.fileName);

        String remoteFile = TLCTripRecordExportDlg.fileName;
  FileInputStream inputStream = new FileInputStream(f);
  ProgressMonitorInputStream pmiStream = new ProgressMonitorInputStream(this,"Uploading the File",inputStream);
//      OutputStream os = ftpClient.storeFileStream(remoteFile);
//      byte[] buffer = new byte[1024];
//      int len;
//      while ((len = pmiStream.read(buffer)) != -1)
//      {
//          os.write(buffer, 0, len);
//          os.flush();
//      }
//      pmiStream.close();
//      os.close();


  if(ftpClient.storeFile(remoteFile, pmiStream)){
    inputStream.close();
    pmiStream.close();
  }else{

    SwingUtils.showMessage(this, "File Not Uploaded: " + ftpClient.getReplyString());
    return;
  }

存储文件中出现错误。这是堆栈跟踪：

Answer 1

我找到了答案。添加这两行：

        ftpClient.execPROT("P");
        ftpClient.execPBSZ(0);
