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)
{
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$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;
}
?>
文件存储access_token
function getAccessToken() { // access_token 应该全局存储与更新，以下代码以写入到文件中做示例 $data = json_decode(file_get_contents("access_token.json")); if ($data->expire_time < time()) { $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret"; $res = json_decode($this->httpGet($url)); $access_token = $res->access_token; if ($access_token) { $data->expire_time = time() + 7000; $data->access_token = $access_token; $fp = fopen("access_token.json", "w"); fwrite($fp, json_encode($data)); fclose($fp); } } else { $access_token = $data->access_token; } return $access_token; }
