FTP client - listfiles
提问by Raghu
I am unable to get the exact file list using FTPClient. Sample code as below :
我无法使用 FTPClient 获取确切的文件列表。示例代码如下：
FTPClient client = new FTPClient();
client.connect("x.x.x.x");
client.login("abcd", "abcd");
FTPFile[] ftpFiles = client.listFiles();
for (FTPFile ftpFile : ftpFiles) {
System.out.println("FTPFile: " + ftpFile.getName());
}
I tried to set to PASV mode using enterLocalPassiveMode()/enterRemotePassiveMode()/pasv(). But, it doesnt work.
我尝试使用 enterLocalPassiveMode()/enterRemotePassiveMode()/pasv() 设置为 PASV 模式。但是，它不起作用。
Please also check Apache Commons FTPClient.listFiles..
另请检查Apache Commons FTPClient.listFiles..
Thank you
谢谢

I don't know what filesis, but you're getting the results of client.listFilesin ftpFiles, and not in files. Then in your forloop you go over files.
我不知道是什么files，但你得到的结果是client.listFilesin ftpFiles，而不是 in files。然后在你的for循环中你过去了files。

Try this.
试试这个。
String[] fileFtp = client.listNames();//if it is directory. then list of file names
//download file
for (int i =0;i<fileFtp.length;i++) {
String fileName = fileFtp[i];
OutputStream out = new FileOutputStream(new File("local temp file name"));
if (!client.retrieveFile(fileName, out)) {
sysout("Could not download the file. "+ fileName);
} else {
sysout("Downloaded file @ : "+localFileName);
}
}
This should work.
Thanks.
这应该有效。
谢谢。
