PayPal
PayPal, 全球众多用户使用的国际贸易支付工具, 能够轻松完成境外收付款! 一个账户全球通用, 成为PayPal商家, 就能在任何地方接受更多付款方式。
下载paypal sdk
在 composer.json 中加入 “paypal/rest-api-sdk-php” : “1.7.4”,如图:
执行composer update
注册开发者账号,创建测试应用,测试账户
地址:
https://developer.paypal.com
创建沙盒测试账户
账号后台(可以看到自己的消费记录):
https://www.sandbox.paypal.com/signin?returnUri=https%3A%2F%2Fwww.sandbox.paypal.com%2Fmyaccount%2Fsummary&state=%2F
创建应用
查看应用配置
点击创建的应用,查看配置Client ID,Secret,后面请求接口需要用到,sandbox为测试环境,live为线上环境
新建测试账号
可设置金额及密码
接入代码
下单逻辑
<?php namespace App\Http\Controllers\Api; use Illuminate\Http\Request; use App\Http\Controllers\Controller; use PayPal\Api\Payer; use PayPal\Api\Item; use PayPal\Api\ItemList; use PayPal\Api\Details; use PayPal\Api\Amount; use PayPal\Api\Transaction; use PayPal\Api\RedirectUrls; use PayPal\Api\Payment; use PayPal\Auth\OAuthTokenCredential; use PayPal\Exception\PayPalConnectionException; use PayPal\Rest\ApiContext; use PayPal\Api\PaymentExecution; class paypalController extends Controller { const clientId = 'xxxxxxxxx';//应用Client ID const clientSecret = 'xxxxxxxx';//Secret const accept_url = 'http://xxx.laravel.com/Api/paypal/Callback'; //支付成功和取消交易的跳转地址 const Currency = 'USD';//货币单位 protected $PayPal; public function __construct() { $this->PayPal = new ApiContext( new OAuthTokenCredential( self::clientId, self::clientSecret ) ); //如果是沙盒测试环境不设置,请注释掉 // $this->PayPal->setConfig( // array( // 'mode' => 'live', // ) // ); } /** * @param * $product 商品 * $price 价钱 * $shipping 运费 * $description 描述内容 */ public function pay() { $product = '1123'; $price = 1; $shipping = 0; $description = '1123123'; $paypal = $this->PayPal; $total = $price + $shipping;//总价 $payer = new Payer(); $payer->setPaymentMethod('paypal'); $item = new Item(); $item->setName($product)->setCurrency(self::Currency)->setQuantity(1)->setPrice($price); $itemList = new ItemList(); $itemList->setItems([$item]); $details = new Details(); $details->setShipping($shipping)->setSubtotal($price); $amount = new Amount(); $amount->setCurrency(self::Currency)->setTotal($total)->setDetails($details); $transaction = new Transaction(); $transaction->setAmount($amount)->setItemList($itemList)->setDescription($description)->setInvoiceNumber(uniqid()); $redirectUrls = new RedirectUrls(); $redirectUrls->setReturnUrl(self::accept_url . '?success=true')->setCancelUrl(self::accept_url . '/?success=false'); $payment = new Payment(); $payment->setIntent('sale')->setPayer($payer)->setRedirectUrls($redirectUrls)->setTransactions([$transaction]); try { $payment->create($paypal); } catch (PayPalConnectionException $e) { echo $e->getData(); die(); } $approvalUrl = $payment->getApprovalLink(); header("Location: {$approvalUrl}"); }
走完下单逻辑会跳转到paypal的支付页面,第一次需要输入账号密码,如图:
进入支付页面,选择Paypal余额支付,支付完成或取消交易会自动跳转到你下单时传的跳转地址,并会传两个参数 paymentId(paypal订单号),PayerID(用户id),你可以根据你的业务逻辑写对应逻辑,一般同步回调确认用户是否付款,异步回调处理业务逻辑
同步回调
/** * 回调 */ public function Callback() { $success = trim($_GET['success']); if ($success == 'false' && !isset($_GET['paymentId']) && !isset($_GET['PayerID'])) { echo '取消付款';die; } $paymentId = trim($_GET['paymentId']); $PayerID = trim($_GET['PayerID']); if (!isset($success, $paymentId, $PayerID)) { echo '支付失败';die; } if ((bool)$_GET['success'] === 'false') { echo '支付失败,支付ID【' . $paymentId . '】,支付人ID【' . $PayerID . '】';die; } $payment = Payment::get($paymentId, $this->PayPal); $execute = new PaymentExecution(); $execute->setPayerId($PayerID); try { $payment->execute($execute, $this->PayPal); } catch (Exception $e) { echo ',支付失败,支付ID【' . $paymentId . '】,支付人ID【' . $PayerID . '】';die; } echo '支付成功,支付ID【' . $paymentId . '】,支付人ID【' . $PayerID . '】';die; }
异步回调
回调地址配置在后台,地址必须为https开头,设置一般过一段时间才会生效(我是下午申请,第二天上午才生效的,如图:
你可以勾选很多事件发送通知,不过最重要的还是支付完成(Payment sale completed)以及退款(Payment sale refunded)
支付完成
public function notify(){ //获取回调结果 $json_data = $this->get_JsonData(); if(!empty($json_data)){ Log::debug("paypal notify info:\r\n".json_encode($json_data)); }else{ Log::debug("paypal notify fail:参加为空"); } //自己打印$json_data的值看有那些是你业务上用到的 //比如我用到 $data['invoice'] = $json_data['resource']['invoice_number']; $data['txn_id'] = $json_data['resource']['id']; $data['total'] = $json_data['resource']['amount']['total']; $data['status'] = isset($json_data['status'])?$json_data['status']:''; $data['state'] = $json_data['resource']['state']; try { //处理相关业务 } catch (\Exception $e) { //记录错误日志 Log::error("paypal notify fail:".$e->getMessage()); return "fail"; } return "success"; } public function get_JsonData(){ $json = file_get_contents('php://input'); if ($json) { $json = str_replace("'", '', $json); $json = json_decode($json,true); } return $json; }
处理退款
public function returnMoney() { try { $txn_id = "xxxxxxx"; //异步加调中拿到的id $amt = new Amount(); $amt->setCurrency('USD') ->setTotal('99'); // 退款的费用 $refund = new Refund(); $refund->setAmount($amt); $sale = new Sale(); $sale->setId($txn_id); $refundedSale = $sale->refund($refund, $this->PayPal); } catch (\Exception $e) { // PayPal无效退款 return json_decode(json_encode(['message' => $e->getMessage(), 'code' => $e->getCode(), 'state' => $e->getMessage()])); // to object } // 退款完成 return $refundedSale; }

总结
paypal对于扩展海外支付的业务还是很有帮助的,它支持多种货币,可绑定各种信用卡,银行卡,缺点是接入时不会有paypal技术人员和你对接,反正我是在接入完成之后才联系到paypal对接人的,好在接入难度不大,网上资料比较丰富,希望此文章可以给各位带来帮助,对于海外支付有兴趣的可以和我来讨论。
