需要SFTP InputStream的URL(need URL for SFTP InputStream)

 我正在编写一个需要通过sftp连接到服务器上的GATE数据存储的应用程序。 为了打开数据存储，我需要有它的网址。 我在Jsch类的帮助下通过sftp和公钥/私钥授权访问数据存储。 
 
 我可以通过ChannelSftp获取数据，然后获取相应目录的InputStream 。 我试图用sftp.getHome()来获取路径，但是这只给了我相对路径。 但是，为了连接到数据存储，我需要这样的东西： 
 
"sftp://path/to/datastore"
 
 有没有办法获得sftp InputStream的url？ 
 
 我知道我可以将InputStream中的数据加载到本地文件中，但我不想那样做，因为数据存储很大。 我也知道我可以通过在URL中输入用户名和密码来连接到sftp，但我想使用公钥。 

I am writing an application that needs to connect via sftp to a GATE datastore that is living on a server. In order to open the datastore, I need to have the url for it. I am accessing the datastore through sftp and public/private key authorization with help of the Jsch class.
 
I can get to the data with ChannelSftp and then get an InputStream for the respective directory. I tried to get the path with sftp.getHome(), but that only gives me the relative path. In order to connect to the datastore, though, I need something like:
 
"sftp://path/to/datastore"
 
Is there a way to get the url of the sftp InputStream?
 
I know I could load the data from the InputStream to a local file, but I don't want to do that, because the datastore is huge. I also know that I can connect to sftp by putting username and password in the url, but I want to use a public key.
