android接入支持海外的支付，visa，mastercard

为了支持海外的支付，我真的是找遍了各种方法，研究过google支付，最后因为手续费太高放弃。最后还是找到了支付宝海外支付。

sdk文档地址：http://www.alipay-seller.mpymnt.com/node/82（对，只有英文文档，没有中文）

该渠道支持的visa、mastercard、jcb等信用卡，既然是信用卡支付，是有一定的失败概率的，没有开通国际汇款的信用卡不能支付（这个目前我们应用测试结果是这样子的）。

国内的信用卡不能支付，不管是双币还是其他（这个很忧伤）。我在测试环境测试好后，只能麻烦海外用户帮忙测试。。。

下面我把基本步骤给贴出来，还有一些注意事项。

开发前的准备工作

申请注册webhook  http://www.alipay-seller.mpymnt.com/node/35《－－这里有说明

按照文档说，发送申请邮件到指定邮箱，在发之前，最好跟支付宝技术人员先联系上，说明想接入他们这个sdk。否则人家看到你发的邮件都不知道是多久以后了。

webhook的作用：主要是通知我们的服务端，支付结果。

1、选择下载哪个demo

官方网站有三个demo（mCommerce Sample App、CheckoutScreens Sample App、Tokenization Sample）,我接入的是第一个，

第二个放入我们工程会报错，第三个支付宝技术人员说不要用（我就想既然建议不要用，为何要有）。

下面我说的，就是按照demo里面的代码该注意的地方重点说明。

下面的这个两个参数，测试环境下就按照官方给的值，不用改。在正式环境中，建议吧这两个值放在服务端。

在测试环境中.初始化initializaProvider(PWProviderMode.TEST,

APPLICATIONIDENTIFIER, PROFILETOKEN);  正式环境中记得改成PWProviderMode.LIVE.

创建订单，

这里我选择的是美元收款，文档里面可以有多种收款币种选择的。最后支付宝会结算成人民币给我们。信用卡类型，我总共就用两个visa和mastercard。两种充值类型逻辑都是一样的，唯一的区别就是这个PWCreditCardType.VISA还是PWCreditCardType.MASTERCARD.根据自己的需求。

创建订单后要选择对订单中哪些数据进行风控。这个风控系统是支付宝自己的系统，主要判断订单的风险性，他们自己有套过滤标准。

这个demo里面绝对没有，除非后面更新了。

这里的美元单位是要美分的

设置订单号：

paymentParams.setCustomIdentifier(orderNum+"");

发起注册预授权（pa）

_binder.createAndRegisterPreauthorizationTransaction(paymentParams);

在回调函数

creationAndRegistrationSucceeded中

发起pa：

_binder.preauthorizeTransaction(transaction);

pa成功后，注册cp：

_binder.createAndRegisterCaptureTransaction(paymentParams, transaction.getMobileIdentifier());

注册cp成功，发起cp：

_binder.captureTransaction(transaction);

下面讲讲服务端的处理的时候注意事项（.net）

服务端测试的通知回调地址是：https://test.payworks.io

服务端正式的通知回调地址是：https://api.payworks.io

服务端需要有ssl证书的，我测试的时候没有ssl证书，有时候会出现因为这个失败

下面是我们服务端的主要代码
