Description:
------------
CURLOPT_SSH_PUBLIC_KEYFILE and CURLOPT_SSH_PRIVATE_KEYFILE are not documented. They are useful when we require to scp or sftp a file thru curl api.
I could achieve successful sftp using above said curl_setopts
Test script:
---------------
<?php
$certPath="/home/y/conf/yapache/ssh-keys/akamai.id_rsa.pub";
$keyPath="/home/y/conf/yapache/ssh-keys/akamai.id_rsa";
error_reporting(E_ALL);
ini_set('display_errors', 1);
$ch = curl_init();
$localfile = 'scp-small-file.txt';
$fp = fopen($localfile, 'r');
curl_setopt($ch, CURLOPT_URL, 'sftp://@72.246.194.54/21996/'.$localfile);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch,CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_PROTOCOLS, CURLPROTO_SFTP);
curl_setopt($ch, CURLOPT_SSH_PUBLIC_KEYFILE, $certPath);
curl_setopt($ch, CURLOPT_SSH_PRIVATE_KEYFILE, $keyPath);
curl_setopt($ch, CURLOPT_USERPWD,'sshacs');
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
curl_exec ($ch);
$error_no = curl_errno($ch);
curl_close ($ch);
if ($error_no == 0) {
$error = 'File uploaded succesfully.';
} else {
$error = 'File upload error.';
}
echo $error.' '.$error_no;
