我正在尝试进行非常简单的文件上传.我想要一个可以上传我告诉它的任何文件的 Java FTPClient.但是 pdf 总是一团糟,我的 pdf 编辑器 (Adobe) 不会打开它,说存在 I/O 错误.
I'm trying to do a VERY simple file upload. I want a Java FTPClient that can upload any file I tell it to. But the pdf always gets all messed up and my pdf editor (Adobe) won't open it, saying there is an I/O error.
我正在使用以下类:
import org.apache.commons.net.ftp.FTPClient;
....
FTPClient client = new FTPClient();
FileInputStream fis = null;
try {
client.connect("mydomain.com");
client.login("user", "password");
String filename = "myPDF.pdf";
fis = new FileInputStream(filename);
client.storeFile("temp.pdf", fis);
fis.close();
client.logout();
} catch (IOException e) {
e.printStackTrace();
}
为什么这不起作用,我该如何解决?
Why doesn't this work, and how do I fix it?
因为 FTPClient 是 FTP.ASCII_FILE_TYPE
.您只需要更新配置即可以二进制模式传输.
It doesn't work because the default transfer mode for FTPClient is FTP.ASCII_FILE_TYPE
. You just need to update the configuration to transfer in binary mode.
