### 一、前言 ###

本文将基于 `springboot+沙箱环境` 来简单实现支付宝的`电脑网站支付`功能

### 二、获取所需配置参数信息 ###

1.  APPID
2.  支付宝网关
3.  支付宝公钥
4.  RSA2私钥

`登录支付宝` \-> `研发服务` \-> `沙箱` [https://open.alipay.com/platform/appDaily.htm?tab=info][https_open.alipay.com_platform_appDaily.htm_tab_info]

### 三、官网提供的电脑网站支付 Demo ###

> [https://opendocs.alipay.com/open/270/106291][https_opendocs.alipay.com_open_270_106291]  
> 注：这个demo就自己tomcat跑一下看看吧，比较简单，记得修改一下`AlipayConfig`配置文件参数即可~

#### 1、`pom.xml`中新增依赖 ####

<dependency>
         <groupId>com.alipay.sdk</groupId>
         <artifactId>alipay-sdk-java</artifactId>
         <version>4.15.6.ALL</version>
     </dependency>

#### 2、`application.yml`中添加配置 ####

> 根据自己的配置修改即可

alipay:
      # 应用ID,您的APPID，收款账号既是您的APPID对应支付宝账号
      app_id: xxx
      # 商户私钥，您的PKCS8格式RSA2私钥
      merchant_private_key: xxx
      # 支付宝公钥,查看地址：https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。
      alipay_public_key: xxx
      # 服务器异步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数 [需外网能访问]
      notify_url: http://tw6zc5.natappfree.cc/error.html
      # 页面跳转同步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数 [需外网能访问]
      return_url: http://tw6zc5.natappfree.cc/success
      # 签名方式
      sign_type: RSA2
      # 字符编码格式
      charset: utf-8
      # 支付宝网关
      gatewayUrl: https://openapi.alipaydev.com/gateway.do
      # 日志路径
      log_path: "log/"

#### 3、配置类 ####

@Data
    @Configuration
    @ConfigurationProperties(prefix = "alipay", ignoreUnknownFields = false)
    public class AlipayConfigProperty { 
    
        /** * 应用ID,您的APPID，收款账号既是您的APPID对应支付宝账号 */
        public String app_id;
    
        /** * 商户私钥，您的PKCS8格式RSA2私钥 */
        public String merchant_private_key;
    
        /** * 支付宝公钥,查看地址：https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。 */
        public String alipay_public_key;
    
        /** * 服务器异步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问 */
        public String notify_url;
    
        /** * 页面跳转同步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问 */
        public String return_url;
    
        /** * 签名方式 */
        public String sign_type;
    
        /** * 字符编码格式 */
        public String charset;
    
        /** * 支付宝网关 */
        public String gatewayUrl;
    
        /** * 日志路径 */
        public String log_path;
    
    }

#### 4、测试支付接口 ####

@Slf4j
    @Controller
    @RequestMapping("")
    @Api(tags = { "测试支付接口"})
    public class TestController { 
    
        @Autowired
        private AlipayConfigProperty alipayConfigProperty;
    
        @GetMapping("/index")
        public String index() { 
            return "index.html";
        }
    
        // http://127.0.0.1:8080/alipay
        @ApiOperation("支付")
        @GetMapping(value = "alipay")
        @ResponseBody
        @SneakyThrows(Exception.class)
        public String alipay() { 
            //获得初始化的AlipayClient
            AlipayClient alipayClient = new DefaultAlipayClient(alipayConfigProperty.gatewayUrl, alipayConfigProperty.app_id, alipayConfigProperty.merchant_private_key, "json", alipayConfigProperty.charset, alipayConfigProperty.alipay_public_key, alipayConfigProperty.sign_type);
    
            //设置请求参数
            AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
            alipayRequest.setReturnUrl(alipayConfigProperty.return_url);
            alipayRequest.setNotifyUrl(alipayConfigProperty.notify_url);
    
            //商户订单号，商户网站订单系统中唯一订单号，必填
            String out_trade_no = "008";
            //付款金额，必填
            String total_amount = "1";
            //订单名称，必填
            String subject = "测试-商品名称";
            //商品描述，可空
            String body = "测试-商品描述";
    
            alipayRequest.setBizContent("{\"out_trade_no\":\"" + out_trade_no + "\","
                    + "\"total_amount\":\"" + total_amount + "\","
                    + "\"subject\":\"" + subject + "\","
                    + "\"body\":\"" + body + "\","
                    + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
    
            //若想给BizContent增加其他可选请求参数，以增加自定义超时时间参数timeout_express来举例说明
            //alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\","
            // + "\"total_amount\":\""+ total_amount +"\","
            // + "\"subject\":\""+ subject +"\","
            // + "\"body\":\""+ body +"\","
            // + "\"timeout_express\":\"10m\","
            // + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
            //请求参数可查阅【电脑网站支付的API文档-alipay.trade.page.pay-请求参数】章节
    
            //请求
            String result = alipayClient.pageExecute(alipayRequest).getBody();
            log.info("[支付] 请求响应结果：{}", result);
            return result;
        }
    
    
        @ApiOperation("支付成功回调")
        @GetMapping(value = "success")
        @SneakyThrows(Exception.class)
        public String alipaySuccess(HttpServletRequest request) { 
            //获取支付宝GET过来反馈信息
            Map<String, String> params = new HashMap<>();
            Map<String, String[]> requestParams = request.getParameterMap();
            for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext(); ) { 
                String name = iter.next();
                String[] values = requestParams.get(name);
                String valueStr = "";
                for (int i = 0; i < values.length; i++) { 
                    valueStr = (i == values.length - 1) ? valueStr + values[i]
                            : valueStr + values[i] + ",";
                }
                //乱码解决，这段代码在出现乱码时使用
                valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
                params.put(name, valueStr);
            }
    
            // 验签
            boolean signVerified = AlipaySignature.rsaCheckV1(params, alipayConfigProperty.alipay_public_key, alipayConfigProperty.charset, alipayConfigProperty.sign_type); //调用SDK验证签名
    
            // 请在这里编写您的程序（以下代码仅作参考）——
            if (signVerified) { 
                //商户订单号
                String out_trade_no = new String(request.getParameter("out_trade_no").getBytes("ISO-8859-1"), "UTF-8");
    
                //支付宝交易号
                String trade_no = new String(request.getParameter("trade_no").getBytes("ISO-8859-1"), "UTF-8");
    
                //付款金额
                String total_amount = new String(request.getParameter("total_amount").getBytes("ISO-8859-1"), "UTF-8");
    
                log.info("trade_no:" + trade_no + "<br/>out_trade_no:" + out_trade_no + "<br/>total_amount:" + total_amount);
                return "success.html";
            } else { 
                log.error("验签失败");
                return "error.html";
            }
        }
    
    }

#### 5、回调成功/失败 html页面 ####

success.html

<!DOCTYPE html>
    <html>
    <head>
        <meta charset="utf-8">
        <title></title>
    </head>
    <body>
    <h1>SUCCESS</h1>
    </body>
    </html>

error.html

<!DOCTYPE html>
    <html>
    <head>
        <meta charset="utf-8">
        <title></title>
    </head>
    <body>
    <h1>ERROR</h1>
    </body>
    </html>

#### 6、运行 ####

调用支付接口 [http://127.0.0.1:8080/alipay][http_127.0.0.1_8080_alipay]

> 温馨小提示：如果出现提示`支付存在钓鱼风险！` ，解决：换个浏览器清除所有缓存再次尝试即可！

支付成功后，会回调我们配置的`return_url`地址，然后处理自己的业务即可…
