用曲线传输图像

PHP

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
// true to return the transfer as a string of the return value
// of 'curl_exec' instead of outputting it directly
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_URL, 'http://localhost/test/curl/receiver.php');
curl_setopt($ch, CURLOPT_POST, true);
$post = array(
  'euro' => '@eurodance.pls',
  'flush' => '@flush_next.png',
  'first_name' => 'Vadim'
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
print_r($response);

从未使用过,也没有必要使用。但应该帮助你开始。

使用curl似乎使用了错误的工具(即当你有锤子时,每个问题看起来都像钉子),基于你所给的,如果scp/sftp不够灵活,为什么不查看scp/sftp,甚至rsync。如果没有,则必须在源服务器上托管该文件并启动curl以请求该文件(即通过HTTP)。
