PHP對接 paypal 支付的方法？這個問題可能是我們?nèi)粘W習或工作經(jīng)常見到的。希望通過這個問題能讓你收獲頗深。下面是小編給大家?guī)淼膮⒖純?nèi)容，讓我們一起來看看吧！
環(huán)境準備
注冊paypal賬號
注冊paypal開發(fā)者賬號
創(chuàng)建沙盒應用APP
下載SDK

composer require paypal/rest-api-sdk-php實現(xiàn)支付
以下是生成支付的代碼片段，偽代碼
function createPayPal(){
$shippingPrice = 2;
$taxPrice = 0;
$subTotal = 26;
$item1 = new PayPal\Api\Item();
$item1->setName("產(chǎn)品2")->setCurrency("USD")->setQuantity(1)->setPrice(10);
$item2 = new PayPal\Api\Item();
$item2->setName("產(chǎn)品1")->setCurrency("USD")->setQuantity(2)->setPrice(8);
$itemList = new PayPal\Api\ItemList();
$itemList->addItems([$item1,$item2]);
// Set payment details
$details = new PayPal\Api\Details();
$details->setShipping($shippingPrice)->setTax($taxPrice)->setSubtotal($subTotal);
// Set payment amount
//注意，此處的subtotal，必須是產(chǎn)品數(shù)*產(chǎn)品價格，所有值必須是正確的，否則會報錯
$total = $shippingPrice + $subTotal + $taxPrice;
$amount = new PayPal\Api\Amount();
$amount->setCurrency("USD")->setTotal($total)->setDetails($details);
// Set transaction object
$transaction = new PayPal\Api\Transaction();
$transaction->setAmount($amount)->setItemList($itemList)->setDescription("這是交易描述")
->setInvoiceNumber(uniqid());//setInvoiceNumber為支付唯一標識符,在使用時建議改成訂單號
$payer = new PayPal\Api\Payer();
$payer->setPaymentMethod('paypal');//["credit_card", "paypal"]
$redirectUrls = new PayPal\Api\RedirectUrls();
$redirectUrl = "http://test.com/redirect/success";//支付成功跳轉(zhuǎn)的回調(diào)
$cancelUrl = "http://test.com/redirect/cancel";//取消支付的回調(diào)
$redirectUrls->setReturnUrl($redirectUrl)->setCancelUrl($cancelUrl);
// Create the full payment object
$payment = new PayPal\Api\Payment();
$payment->setIntent("sale")->setPayer($payer)->setRedirectUrls($redirectUrls)->addTransaction($transaction);
try {
$clientId = "xxxxxx";//上面應用的clientId和secret
$secret = "XXXXXX";
$oAuth = new \PayPal\Auth\OAuthTokenCredential($clientId, $secret);
$apiContext = new \PayPal\Rest\ApiContext($oAuth);
if(env('APP_DEBUG') === false ){
$apiContext->setConfig(['mode' => 'live']);//設置線上環(huán)境,默認是sandbox
}
$payment->create($apiContext);
$approvalUrl = $payment->getApprovalLink();
dd($approvalUrl);//這個是請求支付的鏈接，在瀏覽器中請求此鏈接就會跳轉(zhuǎn)到支付頁面
} catch (\Exception $e) {
dd($e->getMessage());//錯誤提示
}
}
以下是支付成功的回調(diào)代碼片段，偽代碼
function payRedirect(Request $request)
{
$paymentID = $request->get('paymentId');
$payerId = $request->get('PayerID');
$clientId = "xxxxxx";//上面應用的clientId和secret
$secret = "XXXXXX";
$oAuth = new \PayPal\Auth\OAuthTokenCredential($clientId, $secret);
$apiContext = new \PayPal\Rest\ApiContext($oAuth);
if(env('APP_DEBUG') === false ){
$apiContext->setConfig(['mode' => 'live']);//設置線上環(huán)境,默認是sandbox
}
$payment = \PayPal\Api\Payment::get($paymentID, $apiContext);
$execute = new \PayPal\Api\PaymentExecution();
$execute->setPayerId($payerId);
try{
$payment = $payment->execute($execute, $apiContext);//執(zhí)行,從paypal獲取支付結(jié)果
$paymentState = $payment->getState();//Possible values: created, approved, failed.
$invoiceNum = $payment->getTransactions()[0]->getInvoiceNumber();
$payNum = $payment->getTransactions()[0]->getRelatedResources()[0]->getSale()->getId();//這是支付的流水單號，必須保存，在退款時會使用到
$total = $payment->getTransactions()[0]->getRelatedResources()[0]->getSale()->getAmount()->getTotal();//支付總金額
$transactionState = $payment->getTransactions()[0]->getRelatedResources()[0]->getSale()->getState();//Possible values: completed, partially_refunded, pending, refunded, denied.
if($paymentState == 'approved' && $transactionState == 'completed'){
//處理成功的邏輯，例如：判斷支付金額與訂單金額，更新訂單狀態(tài)等
return "success";//返回成功標識
}else{
//paypal回調(diào)錯誤,paypal狀態(tài)不正確
return "error";//返回錯誤標識
}
}catch(\Exception $e){
dd($e->getMessage());
}
}退款
退款必須要有支付成功的流水單號
一個流水單號可以進行多次退款
退款成功之后，在賬號的交易記錄中不體現(xiàn)，測試時請登錄測試賬號自己記錄一下余額的變化情況，以確定退款是否成功
商家賬號會減少余額并增加手續(xù)費（手續(xù)費是之前付款多收的），用戶賬號會增加余額
function refundOrder()
{
try{
$refundRequest = new \PayPal\Api\RefundRequest();
$amount = new \PayPal\Api\Amount();
$amount->setCurrency("USD")->setTotal(10);//退總金額
$refundRequest->setAmount($amount);
$refundRequest->setDescription("退款測試");
$sale = new \PayPal\Api\Sale();
$sale->setId("XXXXXXXXX");//支付單號,支付成功時保存的支付流水單號
$clientId = "xxxxxx";//上面應用的clientId和secret
$secret = "XXXXXX";
$oAuth = new \PayPal\Auth\OAuthTokenCredential($clientId, $secret);
$apiContext = new \PayPal\Rest\ApiContext($oAuth);
if(env('APP_DEBUG') === false ){
$apiContext->setConfig(['mode' => 'live']);//設置線上環(huán)境,默認是sandbox
}
$detailedRefund = $sale->refundSale($refundRequest, $apiContext);//調(diào)接口
$refundState = $detailedRefund->getState();//Possible values: pending, completed, cancelled, failed.
//var_dump($refundedSale);
if($refundState == 'completed'){
//退款成功,返回
}else{
dd('paypal 退款失敗, 狀態(tài)不正確');
}
}catch (\Exception $exception){
dd($exception->getMessage());//發(fā)生異常
}
