PHP实现微信获取用户基本信息(openid、头像、昵称)

开发->基本配置->AppID
$appKey = '';   //微信公众平台->开发->基本配置->AppSecret
/* 配置结束 */

//①、获取用户openid
$wxPay = new WxService($appid,$appKey);
$data = $wxPay->GetOpenid();      //获取openid
if(!$data['openid']) exit('获取openid失败');
//②、获取用户信息
$user = $wxPay->getUserInfo($data['openid'],$data['access_token']);
?>
