prepay_id都获取正常，调起支付的时候，报jsapi缺少参数 total_free的问题。那位大神能给看看
下面是PHP的签名代码。现在不知道是获取prepay_id的问题，还是调起支付签名的问题？
//根据prepay_id,
//微信小程序调起支付的参数和签名
$prepay_id = $wechatPayMsg;
//时间戳
$timeStampMini = time() . "";
//随机串
$nonceStr = Order::rand_code();
$package = "prepay_id=" . $prepay_id;
$miniMessage = $config["miniapp_id"] . chr(10) . $timeStampMini. chr(10) .$nonceStr . chr(10) .$package . chr(10);
openssl_sign($miniMessage, $mini_sign, $private_key, 'sha256WithRSAEncryption');
$sign = base64_encode($mini_sign);
$signType = "RSA";
$data = [
"timeStamp" => $timeStampMini,
"nonceStr" => $nonceStr,
"package" => $package,
"signType" => $signType,
"paySign" => $sign
];
您好，查询到该参数日志没有调起支付记录，大概率是您代码里的prepayid传错了，辛苦您再检查下。
请问解决了吗？怎么解决的求教
之前也遇到过，建议下单之后，先把参数写死在小程序里面调试下。
先检查参数是否正确，如果参数都没问题，检查小程序主体和支付商户主体是否一致，如果主体不一致的话也会出现这个错误；主体不一致需要填写授权书才可以使用的

$params = [ 'appId' => $config["miniapp_id"], 'timeStamp' => (string)Formatter::timestamp(), 'nonceStr' => Formatter::nonce(), 'package' => 'prepay_id='.$prepay_id, ]; $params += ['paySign' => Rsa::sign( Formatter::joinedByLineFeed(...array_values($params)), $merchantPrivateKeyInstance ), 'signType' => 'RSA'];参考链接：https://developers.weixin.qq.com/community/develop/doc/000eca8d8143a080bacbecfd351009?_at=1676555520977
这个你要检查统一下单方面的代码。支付金额要整数，必须提交。如果没有提交的话调起微信支付的时候会这样提示。
