通过appid和appsecret获取access_token的定义函数
这里用的是memcache缓存存储用户信息7000秒
<?php
function getAccessToken($appid,$appsecret)
{
$mem = new CacheMemcache();
$acc = $mem->get('access_token_'.$appid);
if (!$acc)
{
$url = "https:///cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret";
$result = https_request($url);
$jsoninfo = json_decode($result, true);
$access_token = $jsoninfo['access_token'];
if ($access_token)
{
$expire = time() + 7000;
$mem = new CacheMemcache();
$mem->set('access_token_'.$appid,$access_token,$expire);
}
}
else
{
$access_token = $acc;
}
return $access_token;
}
?>
