php - 通过 sftp 使用 curl 下载文件

Question

这只会创建一个空文件..文件中没有内容

$host = 'domain.com';
$pass = 'xxx';

$remote = 'sftp://var/www/test.txt';
$local = 'C:\wamp\www\test.txt';

$curl = curl_init();
$file = fopen($local, 'w');
curl_setopt($curl, CURLOPT_URL, $remote);
curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_SFTP);
curl_setopt($curl, CURLOPT_USERPWD, "root:$pass");
curl_setopt($curl, CURLOPT_FILE, $file);
curl_exec($curl);
curl_close($curl);
fclose($file);

解决方案

$host = 'domain.com';
$pass = 'xxx';

$remote = "sftp://root:$pass@$host/var/www/test.txt";
$local = 'C:\wamp\www\test.txt';

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $remote);
curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_SFTP);
curl_setopt($curl, CURLOPT_USERPWD, "root:$pass");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
file_put_contents($local, curl_exec($curl));
curl_close($curl);

Answer 1

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$d = curl_exec($curl);
// data is in $d var, write it somewhere ;)
$local = "/tmp/myfile.txt";
file_put_contents($local, $d);
