对于PayStack，您应该包含官方的接受支付javascript，它将在支付完成时触发一个事件（无论支付是否成功，都会触发此触发器）
注意：我将首先使用系统生成的“参考”（例如[日期]-[随机字符串]）在数据库中插入一条付款记录（包括姓名、电子邮件、金额），然后使用以下 HTML接受付款：
接受付款的 HTML
<form id="paymentForm">
<div class="form-group">
<label for="email">Email Address</label>
<input type="email" id="email-address" required />
</div>
<div class="form-group">
<label for="amount">Amount</label>
<input type="tel" id="amount" required />
</div>
<div class="form-group">
<label for="first-name">First Name</label>
<input type="text" id="first-name" />
</div>
<div class="form-group">
<label for="last-name">Last Name</label>
<input type="text" id="last-name" />
</div>
<div class="form-submit">
<button type="submit" onclick="payWithPaystack()"> Pay </button>
</div>
</form>
<script src="https://js.paystack.co/v1/inline.js"></script>
js是这样的：
const paymentForm = document.getElementById('paymentForm');
paymentForm.addEventListener("submit", payWithPaystack, false);
function payWithPaystack(e) {
e.preventDefault();
let handler = PaystackPop.setup({
key: 'pk_test_xxxxxxxxxx', // Replace with your public key
email: document.getElementById("email-address").value,
amount: document.getElementById("amount").value * 100,
ref: ''+Math.floor((Math.random() * 1000000000) + 1), // generates a pseudo-unique reference. Please replace with a reference you generated. Or remove the line entirely so our API will generate one for you
// label: "Optional string that replaces customer email"
onClose: function(){
alert('Window closed.');
},
callback: function(response){
let message = 'Payment complete! Reference: ' + response.reference;
alert(message);
}
});
handler.openIframe();
}
请确保上面的 ref 使用的是之前生成的 [date]-[random string]。
注意：支付步骤完成后，会触发回调事件。
当然，您不会希望在回调中“提醒消息”，您应该调用（例如通过 ajax）触发 CURL 以“验证/检查”付款状态的 PHP。一个典型的 CRUL 是这样的：
curl https://api.paystack.co/transaction/verify/:reference
-H "Authorization: Bearer YOUR_SECRET_KEY"
-X GET
如果你在PHP中实现curl，会是这样的：
// Generated by curl-to-PHP: http://incarnate.github.io/curl-to-php/
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.paystack.co/transaction/verify/:reference');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
$headers = array();
$headers[] = 'Authorization: Bearer YOUR_SECRET_KEY';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
curl_close($ch);
现在上述 CURL 返回的 $result 将类似于以下之一：
案例 1：成功

案例 3：无效

}
因此，您应该依靠 CURL 返回的状态，根据事务“参考”更新您的数据库（例如，如果数据状态为“成功”，则将您的数据库表的事务记录更新为“PAID”）。
最后，如果数据状态为“成功”，请将用户页面重定向到您的比赛页面。
