# 1、前置 #

1、案列采用java编写

2、介绍PayPal订单整合:  
      https://developer.paypal.com/docs/integration/direct/payments/orders/  
      https://developer.paypal.com/docs/api/orders/v2/

3、会对一些可能出现的坑，或者说我碰到的坑进行标记

5、介最后贴图验证以及做好后的样子

6、创建订单 → 捕获订单 → 查询订单 → 申请退款

7、代码已上传码云,如果起到帮助还请star一下[地址:https://gitee.com/xmaxm/payments\_hodgepodge][https_gitee.com_xmaxm_payments_hodgepodge]

# 2、准备工作 #

## 1、MANEV包: ##

<dependency>
                <groupId>com.paypal.sdk</groupId>
                <artifactId>checkout-sdk</artifactId>
                <version>1.0.2</version>
            </dependency>

## 2、获取Client ID和Secret, 登录地址: [https://developer.paypal.com][https_developer.paypal.com] ##

## 4、登录付款账户:[登录:https://www.sandbox.paypal.com][https_www.sandbox.paypal.com] ##

第三步中获取的账号密码, 账户钱不够, 可以从第三步的编辑中为自己添加测试金额

## 5、登录接受付款的商户:[登录:https://www.sandbox.paypal.com][https_www.sandbox.paypal.com] ##

Unclaimed:这个状态的原因如下:

https://www.paypal.com/c2/smarthelp/article/why-is-my-paypal-payment-unclaimed-faq1490
    无人认领/待处理：如果您的付款尚待处理，则表示收件人尚未接受。有几种原因可能导致您的付款待处理。
    付款可能有待处理，原因是：
    • 收件人尚未注册PayPal帐户。
    • 您将款项汇入了收件人尚未添加到其PayPal帐户的电子邮件地址或电话号码。一旦他们将此信息添加到他们的帐户中，钱就会显示在他们的余额中。
    • 收件人仍在决定是否要接受您的付款。
    • 收款人尚未确认其银行帐户。
    如果您的付款在30天内无人认领/待处理，或者您的付款被拒绝或退款，那么您将获得退款

我的原因是:币单位不一致问题, 因为有汇率的存在, 所以PayPal无法自动收款.  
创建订单时和商户配置的货币单位一致, 就可以直接完成订单

# 2、创建订单 #

@Override
        public CommonResult createOrder(String amount) { 
            PayPalHttpClient client;
            // 设置环境沙盒或生产
            if (true) { 
                client = new PayPalHttpClient(new PayPalEnvironment.Sandbox(clientId, secret));
            } else { 
                client = new PayPalHttpClient(new PayPalEnvironment.Live(clientId, secret));
            }
    
            // 配置请求参数
            OrderRequest orderRequest = new OrderRequest();
            orderRequest.checkoutPaymentIntent("CAPTURE");
            List<PurchaseUnitRequest> purchaseUnits = new ArrayList<>();
            purchaseUnits.add(new PurchaseUnitRequest().amountWithBreakdown(new AmountWithBreakdown().currencyCode(currency).value(amount)));
            orderRequest.purchaseUnits(purchaseUnits);
            orderRequest.applicationContext(new ApplicationContext().returnUrl(notifyURLSuccess).cancelUrl(notifyURLFail));
            OrdersCreateRequest request = new OrdersCreateRequest().requestBody(orderRequest);
    
            HttpResponse<Order> response;
            try { 
                response = client.execute(request);
                Order order = response.result();
                String token = order.id();
                log.debug("payPal 支付操作返回结果: " + order);
    
                String payHref = null;
                String status = order.status();
                if (status.equals("CREATED")) { 
                    List<LinkDescription> links = order.links();
                    for (LinkDescription linkDescription : links) { 
                        if (linkDescription.rel().equals("approve")) { 
                            payHref = linkDescription.href();
                        }
                    }
                }
                Map<String, String> resultMap = new HashMap<String, String>();
                resultMap.put("token", token);
                resultMap.put("payHref", payHref);
    
                return CommonResult.success("SUCCESS", resultMap);
            } catch (IOException ioe) { 
                if (ioe instanceof HttpException) { 
                    HttpException he = (HttpException) ioe;
                    log.error("payPal 下单异常: " + ioe);
                    return CommonResult.failMessage(500, "PayPal支付失败", he.getMessage());
                }
                log.error("payPal 下单异常: " + ioe);
                return CommonResult.fail(500, "NetworkTimeout");
            }
        }

请求上面会得到如下结果, 我们请求一下这个链接, 输入测试账号密码进行支付

{ 
        "code": 200,
        "message": "SUCCESS",
        "data": { 
            "payHref": "https://www.sandbox.paypal.com/checkoutnow?token=96R506274J980111X",
            "token": "96R506274J980111X"
        }
    }

# 3、捕获订单 #

@Override
        public CommonResult captureOrder(String token) { 
            PayPalHttpClient client;
            // 设置环境沙盒或生产
            if (true) { 
                client = new PayPalHttpClient(new PayPalEnvironment.Sandbox(clientId, secret));
            } else { 
                client = new PayPalHttpClient(new PayPalEnvironment.Live(clientId, secret));
            }
            OrdersCaptureRequest request = new OrdersCaptureRequest(token);
    
            try { 
                HttpResponse<Order> response = client.execute(request);
                Order order = response.result();
                String status = order.status();
                if (status.equals("COMPLETED")) { 
                    return CommonResult.success("SUCCESS");
                }
                return CommonResult.success("SUCCESS");
            } catch (IOException ioe) { 
                if (ioe instanceof HttpException) { 
                    HttpException he = (HttpException) ioe;
                    log.error("payPal 捕获订单异常: " + ioe);
                    return CommonResult.failMessage(500, "PayPal支付捕获失败", he.getMessage());
                }
                log.error("payPal 捕获订单异常: " + ioe);
                return CommonResult.fail(500, "NetworkTimeout");
            }
        }

这里捕获失败是因为我已经捕获了订单(一个订单只能捕获一次), 在哪里捕获的请往下看, 支付成功回调

{ 
        "code": 500,
        "message": "PayPal支付捕获失败",
        "data": "{\"name\":\"UNPROCESSABLE_ENTITY\",\"details\":[{\"issue\":\"ORDER_ALREADY_CAPTURED\",\"description\":\"Order already captured.If 'intent=CAPTURE' only one capture per order is allowed.\"}],\"message\":\"The requested action could not be performed, semantically incorrect, or failed business validation.\",\"debug_id\":\"8c7d935811111\",\"links\":[{\"href\":\"https://developer.paypal.com/docs/api/orders/v2/#error-ORDER_ALREADY_CAPTURED\",\"rel\":\"information_link\",\"method\":\"GET\"}]}"
    }

# 4、查询订单 #

@Override
        public CommonResult queryOrder(String token) { 
            PayPalHttpClient client;
            // 设置环境沙盒或生产
            if (true) { 
                client = new PayPalHttpClient(new PayPalEnvironment.Sandbox(clientId, secret));
            } else { 
                client = new PayPalHttpClient(new PayPalEnvironment.Live(clientId, secret));
            }
    
            OrdersGetRequest request = new OrdersGetRequest(token);
    
            try { 
                HttpResponse<Order> response = client.execute(request);
                Order order = response.result();
                return CommonResult.success("SUCCESS", order.status());
            } catch (IOException ioe) { 
                if (ioe instanceof HttpException) { 
                    HttpException he = (HttpException) ioe;
                    log.error("payPal 查询订单异常: " + he.getMessage());
                    return CommonResult.failMessage(500, "PayPal支付查询失败", he.getMessage());
                }
                log.error("payPal 查询订单异常: " + ioe);
                return CommonResult.fail(500, "NetworkTimeout");
            }
        }

状态码请参考最后

{ 
        "code": 200,
        "message": "SUCCESS",
        "data": "COMPLETED"
    }

# 5、申请退款 #

@Override
        public CommonResult refundOrder(String token) { 
            PayPalHttpClient client;
            // 设置环境沙盒或生产
            if (true) { 
                client = new PayPalHttpClient(new PayPalEnvironment.Sandbox(clientId, secret));
            } else { 
                client = new PayPalHttpClient(new PayPalEnvironment.Live(clientId, secret));
            }
    
            // 查询支付订单, 拿到退款订单号
            OrdersGetRequest ordersGetRequest = new OrdersGetRequest(token);
            try { 
                HttpResponse<Order> orderResponse = client.execute(ordersGetRequest);
                Order order = orderResponse.result();
                String captureId = null;
                for (PurchaseUnit purchaseUnit : order.purchaseUnits()) { 
                    for (Capture capture : purchaseUnit.payments().captures()) { 
                        captureId = capture.id();
                    }
                }
                if (captureId == null) { 
                    return CommonResult.fail(500, "PayPal申请退款失败");
                }
                // 申请退款
                CapturesRefundRequest request = new CapturesRefundRequest(captureId);
                HttpResponse<com.paypal.payments.Refund> response = client.execute(request);
                com.paypal.payments.Refund refund = response.result();
                if ("COMPLETED".equals(refund.status())) { 
                    return CommonResult.success("SUCCESS", captureId);
                }
                return CommonResult.fail(500, "PayPal申请退款失败");
            } catch (IOException ioe) { 
                if (ioe instanceof HttpException) { 
                    HttpException he = (HttpException) ioe;
                    log.error("payPal 申请退款异常: " + he.getMessage());
                    return CommonResult.failMessage(500, "PayPal支付查询失败", he.getMessage());
                }
                log.error("payPal申请退款异常: " + ioe);
                return CommonResult.fail(500, "NetworkTimeout");
            }
        }

状态码请参考最后

{ 
        "code": 200,
        "message": "SUCCESS",
        "data": "0LX49400YH7782525"
    }

# 6、支付成功回调通知 #

@Override
        public CommonResult paypalSuccess(HttpServletRequest request) { 
            // 通过 token 查询到订单记录
            String token = request.getParameter("token");
            // 拿到订单记录对订单进行捕获操作
            // 目前测试订单没有保存起来, 就手动填写进来
            return captureOrder(token);
        }

# 7、支付失败回调通知 #

@Override
        public CommonResult paypalFail(HttpServletRequest request) { 
            return CommonResult.fail(500, "FAIL");
        }

# 8：杂谈 #

1、前期有点繁琐, 碰到问题不是太好找到解决方法, 后期感觉也还好

2、货币单位这个很重要, 不然订单不能自动结账, 需要手动处理, 因为汇率问题

3、然后打开网页的这个网速, 确实有点说不过去, 太慢了, 唉

4、代码上传码云地址:https://gitee.com/xmaxm/payments\_hodgepodge

5、捕获订单操作, 一般是直接由回调进行触发, 而不是单独的去调用这个接口

6、订单状态码: [跳转地址:https://developer.paypal.com/docs/api/orders/v2/\#definition-order\_status][https_developer.paypal.com_docs_api_orders_v2_definition-order_status]

8、退款状态码:[跳转地址:https://developer.paypal.com/docs/api/orders/v2/\#definition-refund\_status][https_developer.paypal.com_docs_api_orders_v2_definition-refund_status]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4NjM3NTU4_size_16_color_FFFFFF_t_70_pic_center 7]

提供一个群：807770565，欢迎各位进来尬聊 (人不多, 进了就不要退了, 要不就不进, 跪求留一点人, 人多了就活跃了, 跪谢)
