在PHP中使用cURL从SFTP服务器下载文件时，权限被拒绝 - Permission denied when tring to download file from SFTP server using cURL in PHP

Permission denied when tring to download file from SFTP server using cURL in PHP

我正试图通过集成SFTP和cURL来缩短从SFTP下载文件所需的时间。

我的代码如下:

$host = "192.168.1.1";
$username = "testuser";
$password = "testpass";
$fn = 'testfile.zip';
$remote = "sftp://".$username.":".$password ."@".$host.":22/home/testfolder/saleskits/".$fn;
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $remote); #input
curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_SFTP);
curl_exec($curl);
if (!curl_errno($curl)) {
    $info = curl_getinfo($curl);
    echo 'Took ', $info['total_time'], ' seconds to send a request to ', $info['url'], "'n";
}
else{
    echo 'Curl error: ' . curl_error($curl);
}
curl_close($curl);

，输出是"Curl错误:Could not open remote file for reading: Permission denied"。如何获得权限或更改文件的权限?

文档中cURL URL不包含port。此外，SFTP默认为22，因此在您的示例中它是假的。你可以使用:

$remote = "sftp://".$username.":".$password ."@".$host."/home/testfolder/saleskits/".$fn;
