我找到了自己问题的答案。
import pysftp
srv = pysftp.Connection(host="www.destination.com", username="root",
password="password",log="./temp/pysftp.log")
with srv.cd('public'): #chdir to public
srv.put('C:\Users\XXX\Drop@R_692_2419@\test.txt') #upload file to nodejs/
# Closes the connection
srv.close()
放在srv.put里面srv.cd
