Question

PHP 怎么设置过期时间

Answer 1

<?php
class Qiniu_RS_GetPolicy
{
public $Expires;

public function MakeRequest($baseUrl, $mac) // => $privateUrl
{
$deadline = $this->Expires;
if ($deadline == 0) {
$deadline = 3600;
}
$deadline += time();

$pos = strpos($baseUrl, '?');
if ($pos !== false) {
$baseUrl .= '&e=';
} else {
$baseUrl .= '?e=';
}
$baseUrl .= $deadline;

$token = Qiniu_Sign($mac, $baseUrl);
return "$baseUrl&token=$token";
}
}

<?php
function Qiniu_RequireMac($mac) // => $mac
{
if (isset($mac)) {
return $mac;
}

global $QINIU_ACCESS_KEY;
global $QINIU_SECRET_KEY;

return new Qiniu_Mac($QINIU_ACCESS_KEY, $QINIU_SECRET_KEY);
}
