snsapi_userinfo方式获取用户信息

config.php 存放appid和appsecret

<?php$config = [    'appid' => '************',    'appsecret' => '*******************',];

test.php跳转并获取code

<?phprequire_once './config.php';$appid = $config['appid'];$redirect_uri = urlencode('http://www.haoyiya.cn/weixin/auth.php');//授权url$url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=$appid&redirect_uri=$redirect_uri&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect";//如果用户同意授权，页面将跳转至 redirect_uri/?code=CODE&state=STATE。header("location:$url");exit;
auth.php获取用户信息
<?phpheader("Content-type:text/html;charset=utf-8");require_once './config.php';//获取codeif (isset($_GET['code'])){    $code = $_GET['code'];}else{    die("NO CODE");}$obj = new snsapi_userinfo;//获取access_token和openid$res = $obj->access_token($config['appid'],$config['appsecret'],$code);//获取用户信息$userInfo = $obj->userInfo($res->access_token,$res->openid);//输出用户信息echo "<h1>";print_r($userInfo);echo "</h1>";/** * Class snsapi_userinfo * 获取用户信息 */class snsapi_userinfo{    //获取access_token和openid    public function access_token($appid,$appsecret,$code){        $url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$appsecret&code=$code&grant_type=authorization_code";        $res = json_decode($this->httpGet($url));        return $res;    }    public function userInfo($access_token,$openid){        $userUrl = "https://api.weixin.qq.com/sns/userinfo?access_token=$access_token&openid=$openid&lang=zh_CN";        $res = json_decode($this->httpGet($userUrl));        return $res;    }    //curl方式获取返回值    public function httpGet($url) {        $curl = curl_init();        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);        curl_setopt($curl, CURLOPT_TIMEOUT, 500);        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, true);        curl_setopt($curl, CURLOPT_URL, $url);        $res = curl_exec($curl);        curl_close($curl);        return $res;    }}
