IJPay 接口

    /**
     * APP支付
     * @param model
     * @param notifyUrl
     * @return {String}
     * @throws {AlipayApiException}
     */
    public static String startAppPay(AlipayTradeAppPayModel model, String notifyUrl) throws AlipayApiException{
        AlipayTradeAppPayResponse response = appPayToResponse(model,notifyUrl);
        return response.getBody();
    }

    /**

     * @param model
     * @param notifyUrl
     * @return {AlipayTradeAppPayResponse}
     * @throws {AlipayApiException}
     */
    public static AlipayTradeAppPayResponse appPayToResponse(AlipayTradeAppPayModel model, String notifyUrl) throws AlipayApiException{
        //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)。
        request.setBizModel(model);
        request.setNotifyUrl(notifyUrl);
        //这里和普通的接口调用不同，使用的是sdkExecute
        AlipayTradeAppPayResponse response = AliPayApiConfigKit.getAliPayApiConfig().getAlipayClient().sdkExecute(request);
        return response;
    }

    /**
     * APP支付
     * @param model
     * @param notifyUrl
     * @return {AlipayTradeAppPayResponse}
     * @throws {AlipayApiException}
     */
    @Deprecated
    public static AlipayTradeAppPayResponse appPay(AlipayTradeAppPayModel model, String notifyUrl) throws AlipayApiException{
        return appPayToResponse(model, notifyUrl);
    }

服务端代码示例

生成订单并返回唤起客户端支付的orderInfo,具体实现如下：

Spring Boot版本Demo

    /**
     * app支付
     */
    @RequestMapping(value = "/appPay")
    @ResponseBody
    public AjaxResult appPay() {
        try {
            AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
            model.setBody("我是测试数据-By Javen");
            model.setSubject("App支付测试-By Javen");
            model.setOutTradeNo(StringUtils.getOutTradeNo());
            model.setTimeoutExpress("30m");
            model.setTotalAmount("0.01");
            model.setPassbackParams("callback params");
            model.setProductCode("QUICK_MSECURITY_PAY");
            String orderInfo = AliPayApi.startAppPay(model, aliPayBean.getDomain() + "/alipay/notify_url");
            result.success(orderInfo);
        } catch (AlipayApiException e) {
            e.printStackTrace();
            result.addError("system error:"+e.getMessage());
        }
        return result;
    }

JFinal版本Demo

    /**
     * app支付
     */
    public void appPay() {
        try {
            AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
            model.setBody("我是测试数据-By Javen");
            model.setSubject("App支付测试-By Javen");
            model.setOutTradeNo(StringUtils.getOutTradeNo());
            model.setTimeoutExpress("30m");
            model.setTotalAmount("0.01");
            model.setPassbackParams("callback params");
            model.setProductCode("QUICK_MSECURITY_PAY");
            String orderInfo = AliPayApi.startAppPay(model, notify_domain + "/alipay/app_pay_notify");
            result.success(orderInfo);
            renderJson(result);

        } catch (AlipayApiException e) {
            e.printStackTrace();
            result.addError("system error");
        }
    }

客户端实现

官方App支付Android集成流程这里就不做过多解释了，下面我们来看看如何使用JPay快速接入Android APP支付。

对微信App支付、支付宝App支付、银联App支付的二次封装,对外提供一个相对简单的接口以及支付结果的回调

GitHub:https://github.com/Javen205/JPay

Gitee:http://gitee.com/Javen205/JPay

使用方法

1、坐标

Step 1. Add it in your root build.gradle at the end of repositories:

    allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

Step 2. Add the dependency

compile 'com.github.javen205.JPay:JPay:latest.release.here'

例如：版本号为0.0.4

compile 'com.github.javen205.JPay:JPay:0.0.4'

2. Android Manifest配置

2.1权限声明

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2.2注册activity

application节点添加如下类容

        <!-- 支付宝支付 -->

        <activity
            android:name="com.alipay.sdk.app.H5PayActivity"
            android:configChanges="orientation|keyboardHidden|navigation|screenSize"
            android:exported="false"
            android:screenOrientation="behind"
            android:windowSoftInputMode="adjustResize|stateHidden" >
        </activity>
        <activity
            android:name="com.alipay.sdk.app.H5AuthActivity"
            android:configChanges="orientation|keyboardHidden|navigation"
            android:exported="false"
            android:screenOrientation="behind"
            android:windowSoftInputMode="adjustResize|stateHidden" >
        </activity>

        <!-- 支付宝支付 end -->

3. 发起支付

如需开启测试模式只需要在OnCreate中添加如下代码。沙箱环境测试APP支付中请使用沙箱版钱包测试

EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);

通过服务端接口获取到orderInfo后唤起App客户端进行支付

JPay.getIntance(mContext).toPay(JPay.PayMode.ALIPAY, orderInfo, new JPay.JPayListener() {
            @Override
            public void onPaySuccess() {
                Toast.makeText(mContext, "支付成功", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPayError(int error_code, String message) {
                Toast.makeText(mContext, "支付失败>"+error_code+" "+ message, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPayCancel() {
                Toast.makeText(mContext, "取消了支付", Toast.LENGTH_SHORT).show();
            }
        });

或者

Alipay.getInstance(mContext).startAliPay(orderInfo, new JPay.JPayListener() {
            @Override
            public void onPaySuccess() {

            }

            @Override
            public void onPayError(int error_code, String message) {

            }

            @Override
            public void onPayCancel() {

            }
        });
