哪种PAYPAL服务更适合网站在线交易? [英] Which PAYPAL service is better for online transaction for website?
问题描述
我正在一个网站上工作，用户必须付费才能使用某些服务.因此，我知道PayPal是我可以使用的服务.用户可以使用借记卡，信用卡，PayPal帐户等进行付款.我知道可以使用PayPal按钮.但是在我的网站上，我想给用户一个选择，以增加他们选择的数量.用户可以支付$ 5或$ 50,000或他们想要的任何费用.我不知道是否可以使用PayPal按钮.
I am working on a website where users will have to pay to use some services. So I know that PayPal is the service I can use. User can pay with debit card, credit card, PayPal account etc. I know that PayPal button can be used for it. But in my website, I want to give user an option to add amount of their choice. User can pay $5 or $50,000 or anything they want. I don't know if I can use PayPal button or not for this.
简而言之，用户将以表格形式输入金额.提交表单后，它将重定向用户到PayPal网站，他们可以在其中支付金额.作为回报，我想确保他们已经从PayPal支付了多少钱，以及交易是否成功等，因此我可以将详细信息存储在数据库中，如果交易成功，用户将获得帐户中的金额余额.
In short user will enter amount in form. After submitting the form, it will redirect user to PayPal site where they can pay the amount. In return, I wanna make sure how much they have paid, and transaction was successful or not etc from PayPal so I can store details in database and if transaction was successful, user will get the amount balance in account.

推荐答案
我建议使用贝宝快速结帐.这里是一个简单的(PHP)示例:
I recommended use a paypal express checkout. Here one simple (PHP) example:
// Parameters for SetExpressCheckout, which will be sent to PayPal
$padata['L_BILLINGAGREEMENTDESCRIPTION0'] = 'Product description';
$padata['L_BILLINGAGREEMENTDESCRIPTION0'] = $padata['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';
$padata['PAYMENTREQUEST_0_CURRENCYCODE'] = 'USD';
$padata['PAYMENTREQUEST_0_PAYMENTACTION'] = 'SALE';
$padata['PAYMENTREQUEST_0_ITEMAMT'] = $product->price;
$padata['PAYMENTREQUEST_0_AMT'] = $product->price;
$padata['L_BILLINGTYPE0'] = 'RecurringPayments';
$padata['L_PAYMENTREQUEST_0_NAME0'] = $product->name;
$padata['L_PAYMENTREQUEST_0_NUMBER0']= '322';
$padata['L_PAYMENTREQUEST_0_QTY0'] = '1';
$padata['L_PAYMENTREQUEST_0_AMT0'] = $product->price;
$paypal_data = http_build_query($padata);
$httpParsedResponseAr = $this->PPHttpPost('SetExpressCheckout', $paypal_data);
//Respond according to message we receive from Paypal
if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])){
//Redirect user to PayPal store with Token received.
$paypalurl ='https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token='.$httpParsedResponseAr["TOKEN"].'';
header('Location: '.$paypalurl);
}else{
echo 'Error : '.urldecode($httpParsedResponseAr["L_LONGMESSAGE0"]).'';
}
页面返回网址:
$hosteddata['L_BILLINGAGREEMENTDESCRIPTION0'] = 'Recurring Description';
$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('Y-m-d') . 'T' . date('H:i:s').'Z';
$hosteddata['SUBSCRIBERNAME'] = $GetExpressCheckoutDetails['FIRSTNAME'] . ' ' . $GetExpressCheckoutDetails['LASTNAME'];
$hosteddata['TOKEN'] = urlencode($_POST['token']);
$hosteddata['DESC'] = $hosteddata['L_BILLINGAGREEMENTDESCRIPTION0'];
$hosteddata['AMT'] = $pr->price;
$hosteddata['BILLINGPERIOD'] = 'Month';
$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'] = 'RecurringPayments';
$hosteddata['L_PAYMENTREQUEST_0_ITEMCATEGORY0'] = 'Digital';
$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);
我使用了一种单独的方法将参数发布到Paypal
private function PPHttpPost( $methodName_, $nvpStr_ ) {
$api_username = 'yourpaypal@email.com';
$api_password = 'QWEQWEWQEQWEQEQWE';
$api_signature = 'WQEQWEQWEQWEWQEQWEQWEQWEQWEQWE.cT';
$api_endpoint = "https://api-3t.paypal.com/nvp";
$version = '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);
$nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$api_password&USER=$api_username&SIGNATURE=$api_signature&$nvpStr_";
curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);
$httpResponse = curl_exec($ch);
if(!$httpResponse) {
exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');
}
// Extract the response details.
$httpResponseAr = explode("&", $httpResponse);
$httpParsedResponseAr = array();
foreach ($httpResponseAr as $i => $value) {
$tmpAr = explode("=", $value);
if(sizeof($tmpAr) > 1) {
$httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
}
}
if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {
exit("Invalid HTTP Response for POST request($nvpreq) to $api_endpoint.");
}
return $httpParsedResponseAr;
}
