公共网络 FTP 问题
我遇到一个问题:我的 FTP 连接似乎正确且未收到错误,但文件未放置在 ftp 服务器上。
我正在使用 commons-net-ftp。
代码:
int retCode = 0;
FTPClient client = new FTPClient();
client.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out)));
InputStream input = null;
try
{
int replyCode;
client.connect(pHostName);
replyCode = client.getReplyCode();
if (!FTPReply.isPositiveCompletion(replyCode))
{
client.disconnect();
logInfo("ftpFile() - FTP Server refused connection");
retCode = 1;
}
else
{
if(client.login(pUserName, pPassword))
{
//default is FTP.ASCII_FILE_TYPE
if(this.isBinaryTransfer())
{
client.setFileType(FTP.BINARY_FILE_TYPE);
}
// Use passive mode as default because most of us are
// behind firewalls these days.
client.enterLocalPassiveMode();
input = new FileInputStream(pLocalFileName);
if(this.isRemoveRemoteFile())
{
client.deleteFile(pRemoteFileName);
client.getReply();
this.logReplyStringInfo(client.getReplyStrings(), "Removing Remote File");
}
if(this.isOverwriteFile())
{
replyCode = client.sendCommand("-O");
this.logReplyStringInfo(client.getReplyStrings(), "Overwrite File");
}
if(!client.storeFile(pRemoteFileName, input))
{
logError("ftpFile() - Not able to store the file on the server" );
retCode = 6;
}
input.close();
client.logout();
client.disconnect();
}
else
{
client.logout();
client.disconnect();
retCode = 3;
}
}
}
catch (FileNotFoundException fileNotFoundException)
{
logError("ftpFile(String, String, String, String, String)", fileNotFoundException); //$NON-NLS-1$
fileNotFoundException.printStackTrace();
retCode = 5;
}
catch (FTPConnectionClosedException e)
{
logError("ftpFile(String, String, String, String, String)", e); //$NON-NLS-1$
retCode = 4;
e.printStackTrace();
}
catch (IOException e)
{
logError("ftpFile(String, String, String, String, String)", e); //$NON-NLS-1$
e.printStackTrace();
e.printStackTrace();
retCode = 2;
}
finally
{
if (client.isConnected())
{
try
{
if(null != input)
{
input.close();
}
client.disconnect();
}
catch (IOException f)
{
logWarning("ftpFile(String, String, String, String, String) - exception ignored", f); //$NON-NLS-1$
}
}
}

对于问题是什么有什么建议吗?有什么可以运行的测试吗?
我可以使用 FileZilla 进行 ftp 和上传文件。
进行进一步的测试,当我从本地开发环境运行时,我能够执行成功的 FTP put - 这是 Windows (Eclipse/JBoss) 但是,当 FTP 从生产服务器 (Linux/JBoss) 运行时,跟踪表明它成功,但 FTP 服务器上未放置任何内容。

Any suggestions as to what the issue is? Any test that can be run?
I can ftp and upload a file using FileZilla.
Doing further testing I am able to execute a successful FTP put when I run from my local dev env - which is Windows (Eclipse/JBoss) But, when the FTP is run from the production servier (Linux/JBoss) The trace indicates that it is successful but nothing is placed on the FTP Server.

Commons FTP 的一些命令要求您调用completePendingCommand:
尝试在storeFile 之后添加以上内容。更多信息在这里:
http ://commons.apache.org/net/api/org/apache/commons/net/ftp/FTPClient.html#completePendingCommand()
A few of the commands with Commons FTP require you to call completePendingCommand:
Try adding the above after storeFile. More info here:
