php实现的ssh api类，php实现sshapi,class SshApi

class SshApi extends BaseObject{   public $session = null;   public $authenticated = false;   public function __construct(){   }   public function connect($host){      $this->session = ssh2_connect($host);      return $this->session;   }   public function pubkeyFile($sshUser, $sshPub, $sshPriv, $sshPass){      if ( ! $this->session ) return false;      if ( empty($sshPass) ){         $b = ssh2_auth_pubkey_file( $this->session, $sshUser, $sshPub, $sshPriv);      }      else         $b = ssh2_auth_pubkey_file( $this->session, $sshUser, $sshPub, $sshPriv, $sshPass);      if ( $b ) $this->authenticated = true;      return $b;   }   public function send($localfile, $remotefile, $perms=0660){      $this->debug(__METHOD__);      if ( ! $this->session ) return false;      $this->debug('Sending '. $localfile .
