Http_request consumer fold studio transmits, as follows

$access_token = "O1AEwcSsQQlPjGlDdI-f_yd8u2mRmpYY_knJaqQ5t5Wl9Wr_TXeWaI0--JPwU3hcjX1GdtpjHn4tAJFmgKeJKOH9K4GPVjcyhR1utGkEAd4RSNiAAAXYT";
$url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=".$access_token;
$openid = "oiPuduCHIBb2aHvZoqSm1t7KbXtw";

    }
}';
$result = https_request($url,$data);
var_dump($result);

function https_request($url, $data = null){
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
