DROP TABLE IF EXISTS `access_token`;
CREATE TABLE `access_token` (

public function getAccessToken(){
  $appid = '你的appid'; //获取用户唯一凭证
  $secret = '你的secret'; //用户唯一凭证密钥
  $time = time()+7000; //当前时间+2小时等于过期时间
  if (!$token) {
    $res = file_get_contents('https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=' .$appid.'&secret='. $secret);
    $res = json_decode($res, true);
    $token = $res['access_token'];
    $model = D('access_token'); //把获取的token存储到数据库中
    if($token){
      $data = array(
      'access_token' => $token,
      'expires_time' => $time
      );
      $data = $model->add($data); //把获得的token存储到数据库中
    }
  }
  return $token;
}

/**
* 添加微信分享接口
* 第二步：用第一步拿到的access_token 采用http GET方式请求获得jsapi_ticket
*/
public function getJsapiTicket(){
  $time = time()+7000; //当前时间+2小时等于过期时间
  $map['ticket_expires_time'] = array('gt',time());
  $res = D('access_token')->where('ticket_expires_time')->field('ticket')->find();
  if($res){
    $ticket = $res['ticket'];
    $result['result'] = $ticket; //没查询到符合条件的
    jsonpReturn($result);
  } else{
    $token = $this->getAccessToken();
    $res = file_get_contents("https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token=".$token."&type=jsapi");
    $res = json_decode($res, true);
    $ticket = $res['ticket'];
    // ticket不能频繁的访问接口来获取，在每次获取后，我们把它保存到数据库中。
    $model = D('access_token'); //把获取的ticket存储到数据库中
    if($ticket){
      $data = array(
      'access_token' => $token,
      'expires_time' => $time,
      'ticket' => $ticket,
      'ticket_expires_time' => $time
      );
      $data = $model->add($data); //把获得的token存储到数据库中
    }
    $result['result'] = $ticket; //没查询到符合条件的
    jsonpReturn($result);
  }
