Since sftpruns over SSH, you can place your public key on the remote server.
由于sftp通过SSH运行，您可以将公钥放在远程服务器上。
If for some reason you can't place your key on the server, then you can write an Expectscript to sendyour password when the prompt appears. See this example.
如果由于某种原因您不能将您的密钥放在服务器上，那么您可以在出现提示时为您的密码编写一个Expect脚本send。请参阅此示例。
