What is the URL in the SFTP case?
[Lin Huangyang] The URL is sftp://xxx.xxx.xxx.xxx, without directory information.

Surely sftp didn't mention 257?

With libcurl you don't "login" to the site the same way your other clients may and I think that adds to the confusion.

With libcurl you specify a URL to libcurl and that includes (an implied or
explicit) directory. Directory treatment of URLs is quite different in FTP compared to SFTP URLs. In FTP you get the user's home directory by default if you don't explicilty ask for an absolute directory, in SFTP you get the root directory by default unless you explicilty ask for the user's home directory.

[Lin Huangyang] Do you mean that I have to explicitly add home directory to sftp URL in order to be at right place once connected? If I don't know the user home directory, is there other way to get to it when connected? Thanks.
