PayPal IPN -不能沙盒

Question

我正试图在我的网站上编写一个简单的PayPal购买页面选项。然而，我在测试时遇到了麻烦。由于一些奇怪的原因，当我使用"http://paypal.com/cgi-bin/webscr"作为表单URL时，它似乎可以工作，但是如果没有人购买，我无法测试IPN。如果我把它留在"http://sandbox.paypal.com/cgi-bin/webscr"，它会弹出这样的PayPal沙盒网站，

由于卖家网站的问题，PayPal无法处理此交易。请直接与卖方联系解决此问题。

下面是我的表单:

<form action="https://www.sandbox.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="YDPZBQ2LRBCSE">
    <table>
    <tr><td><input type="hidden" name="on0" value="Packages">Packages</td></tr><tr><td><select name="os0">
    <option value="Bronze">Bronze $10.00 USD</option>
    <option value="Silver">Silver $25.00 USD</option>
    <option value="Gold">Gold $50.00 USD</option>
    </select> </td></tr>
    <tr><td><input type="hidden" name="on1" value="Wubbo Username">Wubbo Username</td></tr><tr><td><input type="text" name="os1" maxlength="200"></td></tr>
    </table>
    <input type="hidden" name="currency_code" value="USD">
    <input type="image" src="http://wubbo.me/paypal/buynow.png" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">

</form>

我的IPN代码:

<?php
mysql_connect("localhost", "root", "PASSWORD") or die(mysql_error());
mysql_select_db("DATABASE") or die(mysql_error());
// 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($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($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,

    // error_log("Got " . curl_error($ch) . " when processing IPN data");
curl_close($ch);

    // 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
    $package = $_POST['os0'];
    $username = $_POST['os1'];
    if ($package == 'Bronze') {
        mysql_query("UPDATE `users` SET `vip_points` = (`vip_points` + 10) WHERE username = '" . $username . "'");
    } else if ($package == 'Silver') {
        mysql_query("UPDATE `users` SET `vip_points` = (`vip_points` + 30) WHERE username = '" . $username . "'");

    }
}

} else if (strcmp ($res, "INVALID") == 0) {
// IPN invalid, log for manual investigation
echo "The response from IPN was: <b>" .$res ."</b>";

任何帮助都将非常感激!

您应该创建一个沙箱帐户并创建一个沙箱按钮进行测试。要创建一个沙盒账户，你应该访问developer.paypal.com，登录你的PayPal账户，然后按照下面的链接创建一个沙盒帐户(从步骤2开始):https://ppmts.custhelp.com/app/answers/detail/a_id/744/kw/sandbox

创建沙盒帐户后，您可以访问www.sandbox.paypal.com并使用沙盒帐户登录，然后按照下面的链接为沙盒环境创建一个按钮:https://ppmts.custhelp.com/app/answers/detail/a_id/740/kw/create%20button

Answer 2

您得到错误消息是因为您修改了托管按钮。如果你在PayPal上创建按钮，然后在你复制它后更改按钮代码，你会得到这个错误。你需要在PayPal上进行所有修改，或者使用开源按钮。

这是一个开源按钮的例子，你需要从你的PayPal账户添加你自己的电子邮件或商家id，让它工作:
