使用PHP实现Paynamics集成

Question

我有一个需要paynamics支付网关的项目，我已经有了商家id和商家密钥，在提交了包含详细信息和金额的表单后，它必须去支付网址，但交易总是失败。paynamics后台保存成功，但状态为签名验证失败。

$_mid = "xxxxxxxxxxxxxxxxxxxxxx"; //<-- your merchant id
$_requestid = substr(uniqid(), 0, 13);
$_responseid = rand(9,100);
// $_ipaddress = "192.168.10.1";
$_ipaddress = "192.168.51.1";
$_noturl = "http://localhost/aspr/checkout-2/"; // url where response is posted
$_resurl = "http://localhost/aspr/checkout-2/"; //url of merchant landing page
$_cancelurl = "http://localhost/aspr/cancel/"; //url of merchant landing page
$_fname = "Juan"; // kindly set this to first name of the cutomer
$_mname = "O"; // kindly set this to middle name of the cutomer
$_lname = "Dela Cruz"; // kindly set this to last name of the cutomer
$_addr1 = "1609 Cityland 10 HV Dela Costa St.Salecedo Village"; // kindly set this to address1 of the cutomer
$_addr2 = "longos malolos";// kindly set this to address2 of the cutomer

$_phone = "3308772"; // kindly set this to phone number of the cutomer
$_mobile = "09178134828"; // kindly set this to mobile number of the cutomer
$_clientip = $_SERVER['REMOTE_ADDR'];

$_amount = number_format((float)20, 2, '.', ''); // kindly set this to the total amount of the transaction. Set the amount to 2 decimal point before generating signature.
$_currency = "PHP"; //PHP or USD

$forSign = $_mid . 
        $_requestid . 
        $_ipaddress . 
        $_noturl . 
        $_resurl .

        $_clientip . 
        $_amount . 
        $_currency . 
        $_sec3d . 
        "xxxxxxxxxxxxxxxxxxxxxxxxxxx"; //<-- your merchant key


$_sign = hash("sha512", $forSign);

$b64string =  base64_encode($strxml);


 ?>

这是我的提交表格

<form name="surecollect" id="surecollect" method="post" action="https://testpti.payserv.net/webpaymentv2/default.aspx">
    <input type="hidden" name="paymentrequest" value="<?php echo $b64string; ?>">
    <input type="submit" name="submit" value="Submit">
</form>

Answer 1

最近Paynamics有很多变化。请以此repl.it为例，将xxxx替换为Paynamics提供给enter code hereyou的密钥。paynamics.php

确保第41行等于$_amount。公式为Amount = <quantity /> * <amount />

Answer 2

签名是密钥敏感的。你应该把所有字母都小写。
