以下为PHP代码demo.

<?php

//echo phpinfo();
$url=urldecode($_SERVER['REQUEST_URI']);

//echo $url;

$url=parse_url($url);
//print_r($url);
$path=$url['path'];
$path_arry=explode('/', $url['path']);
//print_r($path_arry);
$query_arry=explode('/', $url['query']);
//print_r($_SERVER);
//echo "haojinglong";
//print_r($query_arry);

$exe="convert -resize ".$query_arry[3]."x".$query_arry[5]." ".$path_arry[2]." test_".$path_arry[2];
//echo $exe;
exec($exe,$o,$e);
//print_r($o);
//echo $e;
//print_r($exec_out);
header("Content-type:png");
echo file_get_contents("test_".$path_arry[2]);
?>
