Magento2: How to get content of file from remote sftp?

Question

I have one requirement in which i need to get zip file from remote sftp and read its data after extract it.

I see there is class Magento\Framework\Filesystem\Io\Sftp which i can use like below.

   \Magento\Framework\Filesystem\Io\Sftp $ftp
   ){
       $this->ftp = $ftp;
   }

   public function uploadFile(){
       $open = $this->ftp->open(
                   array(
                       'host' => 'hostname here',
                       'username' => 'username',
                       'password' => 'password'
                   )
               );
}

but how to retrieve files and extract it so i can copy to my server.

Answer 1

You can try using the read() function defined in that same class:

/**
 * Read a file
 *
 * @param string $filename remote file name
 * @param string|null $destination local file name (optional)
 * @return mixed
 */
public function read($filename, $destination = null)
{
    if ($destination === null) {
        $destination = false;
    }
    return $this->_connection->get($filename, $destination);
}

And the code to copy a remote file to your local would be like:

$result = $this->ftp->read('/path/to/remote/filename', '/path/to/local/filename');

$result here is a boolean, which can be used to determine whether it's successful or not.
