我试图在我的网站上销售,而且我是Paypal的新手,我已经阅读了很多教程和文档,但钢铁没有结果。
所以我创建了立即购买按钮,据我所知,过去有许多隐藏输入的按钮,具有重定向网址的支付价值。 ,但现在当我创建按钮时它只是给按钮ID ..这就是它
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick" />
<input type="hidden" name="hosted_button_id" value="JGPBAD3STWN6Q" />
<input type="image" alt="PayPal - The safer, easier way to pay online!" name="submit" src="https://www.paypalobjects.com/en_US/i/btn/btn_buynowCC_LG.gif" />
<img alt="" src="https://www.paypalobjects.com/ru_RU/i/scr/pixel.gif" width="1" height="1" border="0" />
</form>
我在创建按钮时填写的价格和重定向网址。
这是我的ipn代码
<?php
// STEP 1: read POST data
// Reading POSTed data directly from $_POST causes serialization issues with array data in the POST.
// Instead, read raw POST data from the input stream.
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
$keyval = explode ('=', $keyval);
if (count($keyval) == 2)
$myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
$get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
$value = urlencode(stripslashes($value));
} else {
$value = urlencode($value);
}
$req .= "&$key=$value";
}
// STEP 2: POST IPN data back to PayPal to validate
$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
// In wamp-like environments that do not come bundled with root authority certificates,
// please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set
// the directory path of the certificate as shown below:
// curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
if( !($res = curl_exec($ch)) ) {
// error_log("Got " . curl_error($ch) . " when processing IPN data");
curl_close($ch);
exit;
}
curl_close($ch);
// STEP 3: Inspect IPN validation result and act accordingly
if (strcmp ($res, "VERIFIED") == 0) {
// The IPN is verified, process it:
// check whether the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process the notification
// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
// IPN message values depend upon the type of notification sent.
// To loop through the &_POST array and print the NV pairs to the screen:
foreach($_POST as $key => $value) {
echo $key." = ". $value."<br>";
}
} else if (strcmp ($res, "INVALID") == 0) {
// IPN invalid, log for manual investigation
echo "The response from IPN was: <b>" .$res ."</b>";
}
?>
因此,当我试图购买我的产品时,交易似乎没有问题但是当重定向到我的网站代码打印时,来自IPN的回复是:无效
有人可以帮助解决这个问题吗? 谢谢高级

问题出在您的IPN处理程序中,而不是此代码中。显而易见,此代码必须正常工作,否则根本不会发生IPN。您需要发布相关的代码。可能您没有正确构建验证回调URL,或者您没有将其发送到正确的URL(沙箱或实时)。

在表单操作中,您指向 https://www.paypal.com/cgi-bin/webscr
但是在IPN代码中你的
$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');
所以有人指向沙箱,而不指向另一个。这应该是问题。
