PHP：利用curl将接口数据返回

 

　　

//接收微信端的api，返回用户openid
    public function wx_api(){

        $app_id = 'wx3472f272ef0129dc'; //更换新小程序时，应该把小程序开发工具（用appid登录的小程序）+后台服务这边的appid都要更新一下
        $secret = '8cd796a81977df7407ed0908a1492f2e';
        $js_code = $_GET['js_code']; //小程序前端随机生成

        //微信api
        $url="https://api.weixin.qq.com/sns/jscode2session?appid=".$app_id."&secret=".$secret."&js_code=".$js_code."&grant_type=authorization_code";

        $ch=curl_init();
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
        curl_setopt($ch,CURLOPT_URL,$url);
        curl_setopt($ch,CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']);
        $resp=curl_exec($ch);
        curl_close($ch);
        $resp=json_decode($resp,true);
        echo json_encode(array('status'=>1, 'wx_info'=>$resp));
