支付宝支付-PC电脑网站支付

支付产品全面升级(更新时间：2017/05/05 )，若您使用的是老接口，请移步老版本即时到账文档。

支持沙盒环境的测试

此项目已开源欢迎Start、PR、发起Issues一起讨论交流共同进步

1、有图有真相

使用手机扫码进行支付

PC 端登录账号进行支付

2、如何申请PC电脑网站支付

费率、申请条件、签约、使用场景 传送门接入指引

3、如何快速接入PC电脑网站支付

如果你是使用新版本接入就比较方便了，因为官方提供了开放平台服务端SDK

3.1 接口调用流程图

主要涉及到的接口有：

• 支付接口alipay.trade.page.pay

• 退款接口alipay.trade.refund

• 退款查询接口alipay.trade.fastpay.refund.query

• 交易关闭接口alipay.trade.close

• 查询对账单下载地址查询接口alipay.data.dataservice.bill.downloadurl.query

3.2 支付接口alipay.trade.page.pay封装

初始化接口

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

封装支付接口并将SDK生成的表单响应给页面

/**
	 * 电脑网站支付(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();//调用SDK生成表单
		httpResponse.setContentType("text/html;charset=" + CHARSET);
		httpResponse.getWriter().write(form);//直接将完整的表单html输出到页面
	    httpResponse.getWriter().flush();
	    httpResponse.getWriter().close();
	}

3.3 其他支付接口封装

可以参考 支付宝支付-常用支付API详解(查询、退款、提现等)

3.4 封装测试

/**
	 * 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支付测试");
			model.setBody("Javen IJPay PC支付测试");

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

		}

	}

异步通知处理

public void notify_url() {
		try {
			// 获取支付宝POST过来反馈信息
			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) {// 验证成功
				// TODO 请在这里加上商户的业务逻辑程序代码 异步通知可能出现订单重复通知 需要做去重处理
				System.out.println("notify_url 验证成功succcess");
				renderText("success");
				return;
			} else {
				System.out.println("notify_url 验证失败");
				// TODO
				renderText("failure");
				return;
			}
		} catch (AlipayApiException e) {
			e.printStackTrace();
			renderText("failure");
		}
	}

同步商户页面验签，这里只是返回验签的状态

public void return_url() {
		try {
			// 获取支付宝GET过来反馈信息
			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) {// 验证成功
				// TODO 请在这里加上商户的业务逻辑程序代码
				System.out.println("return_url 验证成功");
				renderText("success");
				return;
			} else {
				System.out.println("return_url 验证失败");
				// TODO
				renderText("failure");
				return;
			}
		} catch (AlipayApiException e) {
			e.printStackTrace();
			renderText("failure");
		}
	}

将参数转化为Map，为验签做准备

/**
	 *
	 * @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] + ",";
			}
			// 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);
		}
		return params;
	}
