nginx secure link防盗链 伪静态重写

nginx.conf配置文件

location ~ \.mp4 {
		rewrite ^(.*)/(.*)/(.*)/media/(.+)\.mp4$ $1/media/$4.mp4?s=$2&e=$3 last;
		secure_link $arg_s,$arg_e;
		secure_link_md5 test$uri$arg_e;
		if ($secure_link = "") {
		    return 403;
		}
		if ($secure_link = "0") {
		    return 403;
		}
		mp4;
		mp4_buffer_size       5m;
		mp4_max_buffer_size   50m;
	}

php代码：

$cdn = "http://www.test.com";
$path = "/media/000.mp4";
$secret = "test";
$expire = time() + 3600;  # Link 1 hours expire 1小时过期
$md5 = base64_encode(md5($secret . $path . $expire, true));
$md5 = strtr($md5, '+/', '-_');
$md5 = str_replace('=', '', $md5);
$url = $cdn.$path."?s=".$md5."&e=".$expire;
echo $url."
";
$seo = $cdn."/".$md5."/".$expire.$path;
echo $seo;
