获取是否关注公众号

获取微信用户的信息(普通版)

public function getAccessToken($code)
    {
        // 获取openid
        $appid = WX_PUBLIC_APPID;
        $secret = WX_PUBLIC_APPSECRET;
        $oauth2Url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$secret&code=$code&grant_type=authorization_code";
        $oauth2 = json_decode(file_get_contents($oauth2Url),true);

        if (!isset($oauth2["access_token"])){
            return null;
        }

        $access_token = $oauth2["access_token"]; // 获得 access_token(获取用户信息的access_token) 和openid
        $openid = $oauth2['openid'];

        // 获取用户信息(不包含是否关注公众号字段 - subscribe)
        $get_user_info_url = "https://api.weixin.qq.com/sns/userinfo?access_token=$access_token&openid=$openid&lang=zh_CN";
        $userInfo = json_decode(file_get_contents($get_user_info_url),true);
        return $userInfo;
    }



获取微信用户的信息(包含是否关注公众号信息)

public function getAccessToken($code)
    {
        // 获取openid,因为需要知道是否关注公众所以此次请求 与普通的微信登录不同
        $appid = WX_PUBLIC_APPID;
        $secret = WX_PUBLIC_APPSECRET;
        $oauth2Url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$secret&code=$code&grant_type=authorization_code";
        $oauth2 = json_decode(file_get_contents($oauth2Url),true);

        if (!isset($oauth2["access_token"])){
            return null;
        }
        $openid = $oauth2['openid'];

        // 获取是否关注公众号所需要的access_token
        $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$secret;
        $access = file_get_contents($url);
        $access_arr = json_decode($access,true);
        if (!isset($access_arr["access_token"])){
            return null;
        }
        $new_access_token = $access_arr['access_token'];

        // 获取用户信息
        $get_user_subscribe_url = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$new_access_token."&openid=".$openid."&lang=zh_CN";
        $res = file_get_contents($get_user_subscribe_url);
        $userInfo = json_decode($res,true);
        return $userInfo;
    }
