支付寶支付-PC電腦網站支付

支付產品全面升級(更新時間：2017/05/05 )，若您使用的是老接口，請移步老版本即時到賬文檔。

支持沙盒環境的測試

此項目已開源歡迎Start、PR、發起Issues一起討論交流共同進步

1、有圖有真相

使用手機掃碼進行支付

PC 端登錄賬號進行支付

2、如何申請PC電腦網站支付

費率、申請條件、簽約、使用場景 傳送門接入指引

3、如何快速接入PC電腦網站支付

如果你是使用新版本接入就比較方便了，因爲官方提供了開放平臺服務端SDK

3.1 接口調用流程圖

主要涉及到的接口有：

• 支付接口alipay.trade.page.pay

• 退款接口alipay.trade.refund

• 退款查詢接口alipay.trade.fastpay.refund.query

• 交易關閉接口alipay.trade.close

• 查詢對賬單下載地址查詢接口alipay.data.dataservice.bill.downloadurl.query

3.2 支付接口alipay.trade.page.pay封裝

初始化接口

static {
        alipayClient = new DefaultAlipayClient(SERVICE_URL, APP_ID, PRIVATE_KEY, FORMAT, CHARSET, ALIPAY_PUBLIC_KEY, SIGN_TYPE);
    }

封裝支付接口並將SDK生成的表單響應給頁面

/**
     * 電腦網站支付(PC支付)
     * @param model
     * @param notifyUrl
     * @param returnUrl
     * @return
     * @throws AlipayApiException
     * @throws IOException 
     */
    public static void tradePage(HttpServletResponse httpResponse, AlipayTradePayModel model, String notifyUrl, String returnUrl) throws AlipayApiException, IOException{
        AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
        request.setBizModel(model);
        request.setNotifyUrl(notifyUrl);
        request.setReturnUrl(returnUrl);
        String form  = alipayClient.pageExecute(request).getBody();//調用SDK生成表單
        httpResponse.setContentType("text/html;charset=" + CHARSET);
        httpResponse.getWriter().write(form);//直接將完整的表單html輸出到頁面
        httpResponse.getWriter().flush();
        httpResponse.getWriter().close();
    }

3.3 其他支付接口封裝

可以參考 支付寶支付-常用支付API詳解(查詢、退款、提現等)

3.4 封裝測試

/**
     * PC支付
     */
    public void pcPay(){
        try {
            String totalAmount = "88.88"; 
            String outTradeNo =StringUtils.getOutTradeNo();
            log.info("pc outTradeNo>"+outTradeNo);

            String returnUrl = AliPayApi.NOTIFY_DOMAIN + "/alipay/return_url";
            String notifyUrl = AliPayApi.NOTIFY_DOMAIN + "/alipay/notify_url";
            AlipayTradePayModel model = new AlipayTradePayModel();

            model.setOutTradeNo(outTradeNo);
            model.setProductCode("FAST_INSTANT_TRADE_PAY");
            model.setTotalAmount(totalAmount);
            model.setSubject("Javen PC支付測試");
            model.setBody("Javen IJPay PC支付測試");

            AliPayApi.tradePage(getResponse(),model , notifyUrl, returnUrl);
        } catch (Exception e) {
            e.printStackTrace();

        }

    }

異步通知處理

public void notify_url() {
        try {
            // 獲取支付寶POST過來反饋信息
            Map<String, String> params = AliPayApi.toMap(getRequest());

            for (Map.Entry<String, String> entry : params.entrySet()) {
                System.out.println(entry.getKey() + " = " + entry.getValue());
            }

            boolean verify_result = AlipaySignature.rsaCheckV1(params, AliPayApi.ALIPAY_PUBLIC_KEY, AliPayApi.CHARSET,
                    AliPayApi.SIGN_TYPE);

            if (verify_result) {// 驗證成功
                // TODO 請在這裏加上商戶的業務邏輯程序代碼 異步通知可能出現訂單重複通知 需要做去重處理
                System.out.println("notify_url 驗證成功succcess");
                renderText("success");
                return;
            } else {
                System.out.println("notify_url 驗證失敗");
                // TODO
                renderText("failure");
                return;
            }
        } catch (AlipayApiException e) {
            e.printStackTrace();
            renderText("failure");
        }
    }

同步商戶頁面驗籤，這裏只是返回驗籤的狀態

public void return_url() {
        try {
            // 獲取支付寶GET過來反饋信息
            Map<String, String> map = AliPayApi.toMap(getRequest());
            for (Map.Entry<String, String> entry : map.entrySet()) {
                System.out.println(entry.getKey() + " = " + entry.getValue());
            }

            boolean verify_result = AlipaySignature.rsaCheckV1(map, AliPayApi.ALIPAY_PUBLIC_KEY, AliPayApi.CHARSET,
                    AliPayApi.SIGN_TYPE);

            if (verify_result) {// 驗證成功
                // TODO 請在這裏加上商戶的業務邏輯程序代碼 
                System.out.println("return_url 驗證成功");
                renderText("success");
                return;
            } else {
                System.out.println("return_url 驗證失敗");
                // TODO
                renderText("failure");
                return;
            }
        } catch (AlipayApiException e) {
            e.printStackTrace();
            renderText("failure");
        }
    }

將參數轉化爲Map，爲驗籤做準備

/**
     * 
     * @param request
     * @return
     */
    public static Map<String, String> toMap(HttpServletRequest request) {
        System.out.println(">>>>" + request.getQueryString());
        Map<String, String> params = new HashMap<String, String>();
        Map<String, String[]> requestParams = request.getParameterMap();
        for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext();) {
            String name = (String) iter.next();
            String[] values = (String[]) requestParams.get(name);
            String valueStr = "";
            for (int i = 0; i < values.length; i++) {
                valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ",";
            }
            // 亂碼解決，這段代碼在出現亂碼時使用。
            // valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
            params.put(name, valueStr);
        }
        return params;
    }
