该接口用于用户在商户PC页进行红包的发放，付款时会链接到支付宝PC登录页面进行登录和后续的支付，在支付成功后跳转回商户页。参数详情点击参考文档 我这边分享一下java版的示例供大家参考，适用于jdk版本1.5及以上的开发环境

public class AlipayFundCouponOrderPagePay{
    public static void main(String[] args) throws AlipayApiException {
            //在SDK调用前需要进行初始化
            AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", Config.appId, Config.privateKey, "json","utf-8", Config.alipayPulicKey, "RSA");
            AlipayFundCouponOrderPagePayRequest request = new AlipayFundCouponOrderPagePayRequest();
            AlipayFundCouponOrderPagePayModel model = new AlipayFundCouponOrderPagePayModel();
            ////商户的授权资金订单号 （后面可用此参数用于打款接口）
            model.setOutOrderNo("2017122716463213");
            //商户本次资金操作的请求流水号 
            model.setOutRequestNo("201712271645325");
            model.setOrderTitle("红包页面支付接口发送红包");
            model.setAmount("0.03");
            request.setBizModel(model);
            AlipayFundCouponOrderPagePayResponse response = alipayClient.pageExecute(request,"get");
            if(response.isSuccess()){
                System.out.println("调用成功");
            } else {
                System.out.println("调用失败");
            }
            System.out.println(response.getBody());
    }
}

我们上面使用的是get方式，调用成功则返回访问链接（这个不是同步返回，是请求成功返回）：

https://openapi.alipay.com/gateway.do?alipay_sdk=alipay-sdk-java-dynamicVersionNo&app_id=2016112803499836&biz_content=%7B%22amount%22%3A%220.03%22%2C%22order_title%22%3A%22%E7%BA%A2%E5%8C%85%E9%A1%B5%E9%9D%A2%E6%94%AF%E4%BB%98%E6%8E%A5%E5%8F%A3%E5%8F%91%E9%80%81%E7%BA%A2%E5%8C%85%22%2C%22out_order_no%22%3A%222017122716463213%22%2C%22out_request_no%22%3A%22201712271645325%22%7D&charset=utf-8&format=json&method=alipay.fund.coupon.order.page.pay&return_url=https%3A%2F%2Fopenhome.alipay.com%2FdevelopmentDocument.htm&sign=MPLStxWVevgN6QNH1HjwtkNqM6Y0NNzPj%2B3asC71baZ4MMuHsZ7IK99U9nVoWq0yhvS%2FXXuELgd4CdXQaXCsiEN5okJioJchD4Lp4V4ycFomTOGygFGRhTcM6CqMQps%2Bm0YSaFPxwCa4wBJv%2FBq%2BaunFez3rcDsjFB9fiZYV3VA%3D&sign_type=RSA&timestamp=2017-12-27+16%3A47%3A11&version=1.0&sign=MPLStxWVevgN6QNH1HjwtkNqM6Y0NNzPj%2B3asC71baZ4MMuHsZ7IK99U9nVoWq0yhvS%2FXXuELgd4CdXQaXCsiEN5okJioJchD4Lp4V4ycFomTOGygFGRhTcM6CqMQps%2Bm0YSaFPxwCa4wBJv%2FBq%2BaunFez3rcDsjFB9fiZYV3VA%3D

使用链接访问,则会跳到扫码支付页面，使用手机扫码支付或者登陆账号支付 

如果我们去掉get，直接alipayClient.pageExecute(request);则返回

<form name="punchout_form" method="post" action="https://openapi.alipay.com/gateway.do?charset=utf-8&method=alipay.fund.coupon.order.page.pay&sign=SKLQtYB%2FoM5DdeAmhR8ZecWdxeU9rrRU%2FMSXnxPSkwDvZE7IVe57OOkjYG%2FCKV0rRzr9ThMJDXajUDxNFMzID1Jz3ffHGpOwiF2cDxCOSuYI%2BBwPebLuHXY%2FVG0Yq2gyeM2r8z%2BzFFaTiINbG7lmJfgT3b%2BFPP2Fkc8I2e2YuB4%3D&return_url=https%3A%2F%2Fopenhome.alipay.com%2FdevelopmentDocument.htm&version=1.0&app_id=2016112803499836&sign_type=RSA&timestamp=2017-12-27+16%3A53%3A17&alipay_sdk=alipay-sdk-java-dynamicVersionNo&format=json">
<input type="hidden" name="biz_content" value="{"amount":"0.03","order_title":"红包页面支付接口发送红包","out_order_no":"2017122716463213","out_request_no":"201712271645325"}">
<input type="submit" value="立即支付" style="display:none" >
form>
<script>document.forms[0].submit();script>

将form表单放传入前台访问即可成功显示如上图一样的扫码页面 大家记住这里调用的是 alipayClient.pageExecute(request);不要调用错用execute了，否则会报错的！！！ 如有其它问题，欢迎论坛评论留言，如有不足之处也欢迎多多吐槽！！！
