本文详细介绍了如何使用PayPal支付接口，包括Checkout收银台支付与Subscription订阅支付计划的完整流程。我们将一步步解析这些支付过程，帮助您顺利实现集成。一、生命周期解析1. Checkout - 收银台支付下面是Checkout支付的流程图，类似于支付宝的收银台支付：Checkout流程流程详解：本地应用组装好参数并请求Checkout接口，接口同步返回一个支付URL；本地应用重定向至此URL，用户登录PayPal账户并确认支付，支付后跳转到设置好的本地应用地址；本地请求PayPal执行付款接口发起扣款；PayPal发送异步通知至本地应用，本地收到数据包后进行验签；验签成功后，执行支付后的业务，如修改订单状态、增加销量、发送邮件等。2. Subscription - 订阅支付下面是Subscription支付的流程图：Subscription流程流程详解：创建一个订阅计划；激活该计划；使用激活的计划创建订阅申请；用户授权并完成第一期付款，支付后携带token跳转至设置好的本地应用地址；回跳后请求执行订阅；收到订阅授权的异步回调，验证支付结果，执行支付完成后的业务。二、具体实现Checkout流程在项目中安装PayPal SDK$ composer require paypal/rest-api-sdk-php:* // 使用最新版本 创建PayPal配置文件$ touch config/paypal.php 配置文件内容如下（包括沙箱与生产环境的配置）：<?php return [ 'sandbox' => [ 'client_id' => env('PAYPAL_SANDBOX_CLIENT_ID', ''), 'secret' => env('PAYPAL_SANDBOX_SECRET', ''), 'notify_web_hook_id' => env('PAYPAL_SANDBOX_NOTIFY_WEB_HOOK_ID', ''), ], 'live' => [ 'client_id' => env('PAYPAL_CLIENT_ID', ''), 'secret' => env('PAYPAL_SECRET', ''), 'notify_web_hook_id' => env('PAYPAL_NOTIFY_WEB_HOOK_ID', ''), ], ]; 创建PayPal服务类$ mkdir -p app/Services && touch app/Services/PayPalService.php 代码实现使用PayPal API来执行支付与订阅。以下是服务类的部分代码：namespace App\Services; use PayPal\Api\Currency; use PayPal\Api\Payment; use PayPal\Api\RedirectUrls; use PayPal\Api\Transaction; use PayPal\Api\Payer; use PayPal\Api\Amount; use PayPal\Api\ItemList; use PayPal\Api\Item; use PayPal\Api\PaymentExecution; use Symfony\Component\HttpKernel\Exception\HttpException; class PayPalService { public function checkout(Order $order) { try { $payer = new Payer(); $payer->setPaymentMethod('paypal'); $item = new Item(); $item->setName($order->product->title) ->setDescription($order->no) ->setCurrency($order->product->currency) ->setQuantity(1) ->setPrice($order->total_amount); $itemList = new ItemList(); $itemList->setItems([$item]); $details = new Details(); $details->setShipping(0) ->setSubtotal($order->total_amount); $amount = new Amount(); $amount->setCurrency($order->product->currency) ->setTotal($order->total_amount) ->setDetails($details); $transaction = new Transaction(); $transaction->setAmount($amount) ->setItemList($itemList) ->setDescription($order->no) ->setInvoiceNumber(uniqid()); $redirectUrls = new RedirectUrls(); $redirectUrls->setReturnUrl(route('payment.paypal.return', ['success' => 'true', 'no' => $order->no])) ->setCancelUrl(route('payment.paypal.return', ['success' => 'false', 'no' => $order->no])); $payment = new Payment(); $payment->setIntent('sale') ->setPayer($payer) ->setRedirectUrls($redirectUrls) ->setTransactions([$transaction]); $payment->create($this->apiContext); return $payment->getApprovalLink(); } catch (HttpException $e) { Log::error('PayPal Checkout Create Failed', ['msg' => $e->getMessage(), 'code' => $e->getStatusCode()]); return null; } } } 订阅流程创建订阅计划并激活public function createPlan(Order $order) { try { $plan = new Plan(); $plan->setName($order->no) ->setDescription($order->product->title) ->setType('INFINITE'); $paymentDefinition = new PaymentDefinition(); $paymentDefinition->setAmount(new Currency([ 'value' => $order->product->price, 'currency' => $order->product->currency ])); $plan->setPaymentDefinitions([$paymentDefinition]); $plan->create($this->apiContext); $patch = new Patch(); $value = new PayPalModel('{"state":"ACTIVE"}'); $patch->setOp('replace') ->setPath('/') ->setValue($value); $patchRequest = new PatchRequest(); $patchRequest->addPatch($patch); $plan->update($patchRequest, $this->apiContext); return Plan::get($plan->getId(), $this->apiContext); } catch (HttpException $e) { Log::error('PayPal Create Plan Failed', ['msg' => $e->getMessage()]); return false; } } 常见问题微软邮箱问题：使用outlook、hotmail、live等邮箱注册PayPal账户，升级至GPT Plus或绑定API后会出现账户封禁的问题，建议避免使用这些邮箱。排队等待问题：若在PayPal升级页面看到排队提示，可以尝试使用提供的链接直接进入升级页面，避免排队。取消自动续费：PayPal订阅会默认自动续费，确保在不再需要订阅时手动取消自动续费设置。☞ WildCard | 一分钟注册，轻松订阅海外线上服务使用门槛极低，微信支付宝均可开通使用。支持开通各类海外平台：ChatGPT、Claude、Google Play、Apple Store、OpenAI、X、Patreon、MidJourney、Amazon、POE、Microsoft、Facebook、GitHub、Telegram、PayPal等各类海淘订阅平台。使用邀请码：ACCPAY，立享消费0手续费，减免开卡费用。
