ssh2.sftp问题

wenxin1234114

想在通过php和ssh在远程服务器把一个文件拷贝到本地，之前scp_recv不行，后来用了ssh2_scp也不行，请大神帮看一下，代码如下:

1. if (isset($_POST['download'])) {
   
2.         # code...
   
3.         $ip = $_POST['ip'];
   
4.         $filename=$ip.".tar.gz ";
   
5.         $cmd = "tar zcvf ".$filename.$_POST['path'];
   
6.         $remote_file="/home/test/$filename";
   
7.         $local_file="/tmp/$filename";
   
8.         $conn=ssh2_connect($ip,22,array('hostkey' => 'ssh-rsa' ));
   
9.         ssh2_auth_pubkey_file($conn, 'test', 'test.pub', 'test');
   
10.         $sftp = ssh2_sftp($conn);
    
11.         $stream = @fopen("ssh2.sftp://$sftp$remote_file",'r');
    
12.         @fclose($stream);
    
13.     $data = file_get_contents("ssh2.sftp://$sftp$remote_file");
    
14.     file_put_contents($local_file, $data);
    
15.    
    
16. }

apache日志报错如下：
