招行收款通支付对接来了个国密sm2，sm3，文档也写得不完整，给的demo还是java，哎苦了我们php的，现在直接给出php版本$post_data = [ 'version'=>'2.0', 'merchId'=>$merchId, //商户号 'payNo'=>$payNo, 'orderId' => $orderId, 'feeAmt'=>$money, 'custName'=>$name, 'custPhone'=>$tel, 'userId'=>$userId, 'returnUrl'=>$returnUrl];ksort($post_data);//body SM3$jsonstr=json_encode($post_data);echo 'BODY:'; var_dump($jsonstr);$sign=$sm3->digest($jsonstr,1);//Header SM2$post_data_apisign = array();$post_data_apisign["appid"]=$appid;$post_data_apisign["secret"]=$appsecret;$post_data_apisign["timestamp"]=$timestamp;$post_data_apisign["sign"]=$sign;//$apisign = Sign($post_data_apisign,$privateKey);//签名ksort($post_data_apisign);$post_data_apisign = ToUrlParams($post_data_apisign);$apisign = $sm2->doSign($post_data_apisign,$privateKey,'1234567812345678');$apisign = SM2_Asn1ToRaw($apisign);echo '
