支付宝支付-集成服务端和客户端

服务端 

在pom文件中添加.

        <dependency>
            <groupId>com.alipay.sdk</groupId>
            <artifactId>alipay-sdk-java</artifactId>
            <version>4.10.204.ALL</version>
        </dependency>

 讲一下

sdkExecute和pageExecute的区别.

sdkExecute是作为app的sdk拼接参数来使用.这个后面降到.

pageExecute是作为form表单放入html中.直接转就行

        AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", APPID, APP_PRIVATE, "json", CHARSET, ALIPAY_PUBLIC_KEY, "RSA2");
//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay
        AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。
        AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
        model.setBody("商品");
        model.setSubject("商品名称");
        // 唯一订单号,保证唯一就行
        model.setOutTradeNo(System.currentTimeMillis() + "");
        model.setTimeoutExpress("30m");
        // 价格
        model.setTotalAmount("0.0.1");
        model.setProductCode("QUICK_MSECURITY_PAY");
        request.setBizModel(model);
        request.setNotifyUrl("唤醒地址");
        try {
            //这里和普通的接口调用不同，使用的是sdkExecute
            AlipayTradeAppPayResponse response = alipayClient.sdkExecute(request);
            return response.getBody();
        } catch (AlipayApiException e) {
            e.printStackTrace();
        }
        return "";

客户端操作

   final String orderInfo = "将服务端返回的数据放到这里";
        final Runnable payRunnable = new Runnable() {

            @Override
            public void run() {
                PayTask alipay = new PayTask(PayDemoActivity.this);
                Map<String, String> result = alipay.payV2(orderInfo, true);
                Log.i("msp", result.toString());

                Message msg = new Message();
                msg.what = SDK_PAY_FLAG;
                msg.obj = result;
                mHandler.sendMessage(msg);
            }
        };

        // 必须异步调用
        Thread payThread = new Thread(payRunnable);
        payThread.start();
