我在 Windows 上有一个 Java Web Service 应用程序,现在需要一个 SFTP 进程。我正在尝试使用 JSch 实现 SFTP 以通过 SSH 连接到文件位置,但出现错误:
"com.jcraft.jsch.JSchException: UnknownHostKey: *my_IP_Address*. RSA key fingerprint is a6:54:a8:f7:00:ed:e5:62:6b:ec:60:29:db:eb:ad:0c"
下面的主题类似,但我不能使用“StrictHostKeyChecking”部分,因为我需要维护文件的安全性!
com.jcraft.jsch.JSchException: UnknownHostKey
该解决方案似乎指向将主机文件添加到 .ssh 但所有信息都适用于 Linux\Unix。有人可以告诉我如何在 Windows 上执行此操作吗?
这是有问题的函数(它涉及 MD5 加密,因此引用了 MD5);
public DocumentByteArrayWithChecksum getRawBytesFromFile(String filename)
throws IOException, Exception {
DocumentByteArrayWithChecksum dba = new DocumentByteArrayWithChecksum();
InputStream in = null;
ByteArrayOutputStream out = new ByteArrayOutputStream();
MessageDigest md = MessageDigest.getInstance("MD5");
String SFTPHost = "my_IP_Address";
int SFTPPort = 22; // This is the default sftp port
String SFTPUsername = "my_Username";
String SFTPPassword = "my_Password";
Channel channel = null;
ChannelSftp channelsftp = null;
JSch jsch = new JSch();
com.jcraft.jsch.Session session = jsch.getSession(SFTPUsername,
SFTPHost,
SFTPPort);
try {
session.setPassword(SFTPPassword);
session.connect();
channelsftp = (ChannelSftp)session.openChannel("sftp");
channelsftp.connect();
in = channelsftp.get(filename);
// used to get an MD5 length
in = new DigestInputStream(in, md);
logger.debug("The file is " + filename);
long length = filename.length();
if (length > Integer.MAX_VALUE) {
logger.error("File is too large " + length);
throw new Exception("file exceeds maximum length of "
+ String.valueOf(Integer.MAX_VALUE));
}
byte[] buffer = new byte[(int) length];
int n = 0;
while ((n = in.read(buffer)) != -1) {
out.write(buffer, 0, n);
} // End of while block
} catch(JSchException e) {
System.err
.println("%%%% Error in JSch process %%%%");
e.printStackTrace();
}
catch(Exception e) {
System.err
.println("%%%% Error during getRawBytesFromFile function %%%%");
e.printStackTrace();
}
finally {
in.close();
channelsftp.disconnect();
session.disconnect();
}// End of try block
dba.orginalPDFDocumentChecksum = md.digest();
dba.bytePDFDocument = out.toByteArray();
return dba;
}
谢谢
