[英]FTP file upload failure Java
I use Apache's FTPClient and FTPServer libraries in my Java project. 我在Java项目中使用Apache的FTPClient和FTPServer库。 Server and client are on the same machine.
服务器和客户端在同一台机器上。
My FTPServer is supposed to be a local server,nothing related to the Internet. 我的FTPServer应该是本地服务器,与Internet无关。 I can connect to the FTPServer from the client(I get 230 as reply code) but i cant seem to do anything.
我可以从客户端连接到FTPServer(我得到230作为回复代码),但我似乎无能为力。 I cant store or retrieve any files.
我无法存储或检索任何文件。
I read almost every question related to this matter but people who asked other questions were be able to send simple files and had trouble with sending files like pdf etc. I just need to send or retrieve text files. 我几乎阅读了与此事有关的每一个问题,但是那些提出其他问题的人能够发送简单的文件,并且无法发送像pdf等文件。我只需要发送或检索文本文件。
Any suggestions? 有什么建议么?
FTPClient client = new FTPClient();
String host = "mypc";
String Name = "user";
String Pass = "12345";
client.connect(host);
client.login(Name,Pass);
System.out.println("Reply Code: " +client.getReplyCode());
File file = new File("C:\\.....myfile..txt");
FileInputStream in = new FileInputStream("C:\\.....myfile..txt");
boolean isStored = client.storeFile("uploadedfile.txt", in);
in.close();
client.logout();
System.out.println("isStored: " +isStored);
I didnt put the real path names. 我没有把真正的路径名称。 It returns false,no exceptions etc. This might be because of they're on the same machine?
它返回false,没有异常等。这可能是因为它们在同一台机器上?
Edit: Turned out i needed write permission to send a file to ftpserver. 编辑:原来我需要写权限才能将文件发送到ftpserver。 By default, it doesnt give users write permission.
默认情况下,它不会授予用户写入权限。 How can i give users write permission using Apache's ftpserver library?
如何使用Apache的ftpserver库为用户提供写入权限?
Problem Solved: This is how to give a user write permission. 解决问题:这是如何授予用户写入权限。 I added this snippet to server side and it worked.
我将此代码段添加到服务器端并且它可以正常工作。
List<Authority> auths = new ArrayList<Authority>();
Authority auth = new WritePermission();
auths.add(auth);
user.setAuthorities(auths);
There's term Authority
written in this symbol -> < >
after List
and ArrayList
in the first line. 有一个术语
Authority
写在这个符号 - > < >
在第一行的List
和ArrayList
之后。 Site doesn't see words in <>
symbol. 网站在
<>
符号中看不到单词。
