支付宝公众号授权获取用户信息

1.第一步在蚂蚁开放平台注册申请应用上线

2.下载支付宝秘钥生成器，生成秘钥（加在代码里面）和公钥（填写到蚂蚁开放平台）下载sdk放到extend文件夹里面

3.引用SDK

//头部加上
use think\Loader;
header("Content-type:text/html;charset=utf-8");
Loader::import('alipay.AopSdk', EXTEND_PATH);

4.访问方法拼写授权地址

$encoded_url = 回调地址;
$appid = APPID;
$code_url = "https://openauth.alipay.com/oauth2/publicAppAuthorize.htm?app_id=$appid&scope=auth_user&redirect_uri=".urlencode($encoded_url);//获取auth_code
$this->redirect($code_url);

5.获取用户信息

$code = $_GET['auth_code'];
        //APPID
        $appid = '2018092761533618';
        //应用私钥  文件名（rsa_private_key.pem）
