一旦FTP在java中完成，就会创建0 kb文件 [英] 0 kb file created once FTP is done in java

问题描述

我正在尝试将文件FTP到远程计算机上。下面是我的代码： -

I am trying to FTP a file on to a remote machine. Below is my code :-

FTPClient ftpClient = new FTPClient(); 
ftpClient.connect("home.abc.com"); 
ftpClient.login("remote", "guesst12"); 
int replyCode = ftpClient.getReplyCode(); 
ftpClient.changeWorkingDirectory("share")) 
ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);
InputStream input = new FileInputStream(new File("H:/testFile.txt"));
OutputStream out =  ftpClient.storeFileStream("testFile.txt");
Util.copyStream(input, out);
out.close();
input.close();
ftpClient.completePendingCommand()
ftpClient.logout();
ftpClient.disconnect();

当我执行这段代码时，代码执行没有任何问题，但在远程机器上，当我检查文件时，正在创建文件，但没有内容（OKB）文件。我在代码中遗漏了什么。

When i execute this piece of code, the code is executed without any issues, but at the remote machine, when i check the file, the file is being created, but with no content (OKB) file. Am i missing something in code.

[更新]：
我尝试使用以下代码存储文件： -

[Update] : I tried with the following code for storing file :-

if(ftpClient.storeFile("testCopy.txt", input)) {
    System.out.println("File Stored Successfully");
}
System.out.println(ftpClient.getReplyString());

现在收到的回复代码是： - 451写入本地文件失败。这意味着什么。

Now the reply code i recieved is :- 451 Failure writing to local file. What does that means.

谢谢

推荐答案

经过一遍又一遍的观察，我不断提出不同的事情。

After looking at it over and over I keep coming up with different things.

在复制流之前，你确定InputStream正在读取文件吗？因为我不确定FileInputStream是否在启动时读取了该文件。

Are you sure that the InputStream is reading the file before your copying the stream? Because I'm not sure FileInputStream read's the file on initiation.
