functiongetAccessToken(){
//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);
