php - 如何在没有 PayPal 帐户的情况下取消 PayPal 订阅？

Question

我当前的项目允许用户在不注册贝宝帐户的情况下订阅会员资格。

用户的用户名和密码由我自己的应用程序创建和管理，而不是 PayPal。

谁能告诉我如何创建一个取消订阅的 hTMl 表单？我可以通过发送取消订阅txn_id吗？

我相信我可以使用 IPN 捕获此信息。

我还应该提到，我是一名 DBA，而不是真正的开发人员，所以如果我有点新手，请多多包涵。

提前致谢。

这就是我最终做的事情。

<?php
require 'core/init.php';
require 'core/conn.php';
/*The paypal_transactions table is a table I'm using to store the IPN data.  This is necessary to capture the Profile_ID/Subscr_ID.  The Custom parameter is being used to pass the username.*/

$profileid_sql = "select subscr_id from paypal_transactions where custom ='". escape($user->data()->username)."'";
$result=mysql_query($profileid_sql); 

      while($row=mysql_fetch_array($result)){ 
      $profileid = $row['subscr_id'];
      }


include 'functions/change_subscription_status.php';
change_subscription_status( $profileid, 'Cancel' );
header('Location: Cancelled.php');
?>

change_subscription_status 函数在这里...

<?php

/**
 * Performs an Express Checkout NVP API operation as passed in $action.
 *
 * Although the PayPal Standard API provides no facility for cancelling a subscription, the PayPal
 * Express Checkout  NVP API can be used.
 */
function change_subscription_status( $profile_id, $action ) {

    $api_request = 'USER=' . urlencode( 'API_username' )
                .  '&PWD=' . urlencode( 'API_Password' )
                .  '&SIGNATURE=' . urlencode( 'API_Signature' )
                .  '&VERSION=76.0'
                .  '&METHOD=ManageRecurringPaymentsProfileStatus'
                .  '&PROFILEID=' . urlencode( $profile_id )
                .  '&ACTION=' . urlencode( $action )
                .  '&NOTE=' . urlencode( 'Profile cancelled at store' );

    $ch = curl_init();
    curl_setopt( $ch, CURLOPT_URL, 'https://api-3t.sandbox.paypal.com/nvp' ); // For live transactions, change to 'https://api-3t.paypal.com/nvp'
    curl_setopt( $ch, CURLOPT_VERBOSE, 1 );

    // Uncomment these to turn off server and peer verification
    // curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
    // curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, FALSE );
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt( $ch, CURLOPT_POST, 1 );

    // Set the API parameters for this transaction
    curl_setopt( $ch, CURLOPT_POSTFIELDS, $api_request );

    // Request response from PayPal
    $response = curl_exec( $ch );

    // If no response was received from PayPal there is no point parsing the response
    if( ! $response )
        die( 'Calling PayPal to change_subscription_status failed: ' . curl_error( $ch ) . '(' . curl_errno( $ch ) . ')' );

    curl_close( $ch );

    // An associative array is more usable than a parameter string
    parse_str( $response, $parsed_response );

    return $parsed_response;
}
?>

使用 paypal api 方法 ManageRecurringPaymentsProfileStatus ( API Operation NVP )，使用 ACTION 参数可以：

取消 – 只能取消处于活动或暂停状态的配置文件。
暂停 – 只有处于活动状态的配置文件可以暂停。
重新激活 – 只能重新激活处于暂停状态的配置文件。

贝宝文档 - https://developer.paypal.com/docs/classic/api/merchant/ManageRecurringPaymentsProfileStatus_API_Operation_NVP/

要创建重复配置文件，请遵循以下 (PHP) 示例：

// SetExpressCheckout 的参数，将发送到 PayPal

$pada['L_BILLINGAGREEMENTDESCRIPTION0'] = '产品描述';
$pada['L_BILLINGAGREEMENTDESCRIPTION0'] = $pada['L_BILLINGAGREEMENTDESCRIPTION0'] 。
'$'.$product->price.'/month';
$padata['L_PAYMENTREQUEST_0_DESC0'] = $padata['L_BILLINGAGREEMENTDESCRIPTION0'] 。
'$'.$product->price.'/month'; 
$padata['PAYMENTREQUEST_0_NOTIFYURL'] = 'http://site_url/paypal/ipn';
$padata['PAYMENTREQUEST_0_DESC'] = $product->name;
$padata['RETURNURL'] = 'http://site_url/paypal/returnurl';
$padata['CANCELURL'] = 'http://site_url/paypal/cancelurl';

$pada['PAYMENTREQUEST_0_CURRENCYCODE'] = 'USD';
$pada['PAYMENTREQUEST_0_PAYMENTACTION'] = '销售';
$pada['PAYMENTREQUEST_0_ITEMAMT'] = $product->price; 
$padata['PAYMENTREQUEST_0_AMT'] = $product->price; 
$pada['L_BILLINGTYPE0'] = 'RecurringPayments'; 
$pada['L_PAYMENTREQUEST_0_NAME0'] = $product->name; 
$pada['L_PAYMENTREQUEST_0_NUMBER0']='322'; 
$pada['L_PAYMENTREQUEST_0_QTY0'] = '1'; 
$pada['L_PAYMENTREQUEST_0_AMT0'] = $product->price;


$paypal_data = http_build_query($pada);
$httpParsedResponseAr = $this->PPHttpPost('SetExpressCheckout', $paypal_data);

//根据我们从 Paypal 收到的消息进行响应
if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])){

    //使用收到的令牌将用户重定向到 PayPal 商店。
    $paypalurl ='https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token='.$httpParsedResponseAr["TOKEN"].'';
    header('位置：'.$paypalurl);

}别的{
    echo '错误： '.urldecode($httpParsedResponseAr["L_LONGMESSAGE0"]).'';


}

$hosteddata['L_BILLINGAGREEMENTDESCRIPTION0'] = '重复描述'; 
$hosteddata['L_BILLINGAGREEMENTDESCRIPTION0'] = $hosteddata['L_BILLINGAGREEMENTDESCRIPTION0'] 。'$'.$pr->price.'/month'; 
$hosteddata['L_PAYMENTREQUEST_0_NAME0'] = $pr->name; 
$hosteddata['PROFILEREFERENCE'] = $GetExpressCheckoutDetails['L_PAYMENTREQUEST_0_NUMBER0']; 
$hosteddata['PROFILESTARTDATE'] = date('Ymd') 。'T'。日期('H:i:s').'Z'; 
$hosteddata['SUBSCRIBERNAME'] = $GetExpressCheckoutDetails['FIRSTNAME'] 。' ' 。$GetExpressCheckoutDetails['LASTNAME']; 
$hosteddata['令牌'
$hosteddata['DESC'] = $hosteddata['L_BILLINGAGREEMENTDESCRIPTION0']; 
$hosteddata['AMT'] = $pr->price; 
$hosteddata['BILLINGPERIOD'] = '月'; 
$hosteddata['BILLINGFREQUENCY'] = '1'; 
$hosteddata['TOTALBILLINGCYCLES'] = '12'; 
$hosteddata['REGULARTOTALBILLINGCYCLES'] = '1'; 
$hosteddata['VERSION'] = '74.0'; 
$hosteddata['MAXFAILEDPAYMENTS'] = '1'; 
$hosteddata['L_PAYMENTREQUEST_0_QTY0'] = '1'; 
$hosteddata['L_BILLINGTYPE0'] = ' 经常性付款”；
$hosteddata['L_PAYMENTREQUEST_0_ITEMCATEGORY0'] = '数字';
$hosteddata['L_PAYMENTREQUEST_0_AMT0'] = $pr->price; 
$hosteddata['INITAMT'] = $pr->price; 
$hosteddata['L_PAYMENTREQUEST_0_NUMBER0'] = $pr->id; 
$hosteddata['PAYMENTREQUEST_0_NOTIFYURL'] = 'http://site_url/paypal/ipn';


$paypal_data = http_build_query($hosteddata);
$hosted_saas_response = $this->PPHttpPost('CreateRecurringPaymentsProfile', $paypal_data);

我使用单独的方法将参数发布到贝宝

私有函数 PPHttpPost( $methodName_, $nvpStr_ ) {

$api_username = 'yourpaypal@email.com';
$api_password = 'QWEQWEWQEQWEQEQWE'; 
$api_signature = 'WQEQWEQWEQWEWQEQWEQWEQWEQWEQWE.cT'; 
$api_endpoint = "https://api-3t.paypal.com/nvp"; 
$版本 = '124.0';

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $api_endpoint); 
   curl_setopt($ch, CURLOPT_VERBOSE, 1); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

curl_setopt($ch, CURLOPT_POST, 1); 
 
$nvpreq = "方法=$methodName_&VERSION=$version&PWD=$api_password&USER=$api_username&SIGNATURE=$api_signature&$nvpStr_"; 

curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq); 
$httpResponse = curl_exec($ch);

    如果（！$http响应）{
        exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')'); 
}

    // 提取响应详细信息。
    $httpResponseAr = explode("&", $httpResponse);

    $httpParsedResponseAr = 数组（）；
    foreach ($httpResponseAr as $i => $value) {
        $tmpAr = explode("=", $value);
        如果（大小（$tmpAr）> 1）{
            $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
         }
    }

    if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) { 

        exit("对 $api_endpoint 的 POST 请求 ($nvpreq) 的 HTTP 响应无效。");

    }

    返回 $httpParsedResponseAr;

}

另一种取消方法是在用户帐户内：

登录到您的 PayPal 帐户。
单击页面顶部附近的个人资料。
点击我的钱。
在我的预先批准的付款部分点击更新。
单击取消、取消自动计费或取消订阅，然后按照说明进行操作。
