我收到此错误（550 文件名、目录名或卷标语法不正确。）我认为 url 是正确的（但显然不是）。有什么想法吗？
这是网址：
STOR /images/report/6F81CB22-3D04-4BA3-AC3F-3D34663449E0**9.png
下面是调用方法：
private void uploadImageToFtp(String location, String imageName) throws Exception{
File imageFile = new File(location);
System.out.println("Start");
FTPUploader ftpUploader = new FTPUploader("ftp.xxx.com", "user", "password");
ftpUploader.uploadFile(imageFile, imageName, "/images/report/");
imageFile.delete();
ftpUploader.disconnect();
System.out.println("Done");
}
Here is the
ftp类：
