我们如何在Windows Phone 7中的应用购买中实现 [英] How do we implement in app purchase in windows phone 7

问题描述

我正在创建Windows Phone 7.1应用程序，需要在应用程序内购买

Hi i am creating a windows phone 7.1 application, which requires in app purchases

由于WP7没有像iphone一样具有特定的应用内购买SDK，我们可以使用paypal进行应用内购买

As WP7 does not have a specific in app purchase SDK like iphone does, can we use paypal for in app purchases,

我是Windows Phone 7和Paypal API的新手

I am new to windows phone 7 and paypal API

就像在browsercontrol中打开移动Paypal网站.

like open a mobile paypal site in browsercontrol when i click on payment button and get the payment done by the user and if the payment success return success message or if fail return failure message.

我不认为Movend是最佳选择，因为我们也不得不在他们的网站上维护我不想要的产品数据库.

i do not think Movend is a best option, as we have to maintain products database in their website also which i don't want.

推荐答案

这是我的问题的答案

Paypal没有针对WP7的特定sdk，因此我尝试通过以下方式解决上述问题

Paypal does not have specific sdk for WP7, so i tried to solve above the problem in following way

1. 创建一个网站，该网站将使用查询字符串中的商品价格/详细信息
2. 仅在该网站上实施ExpressCheckout.我已经使用贝宝实现了沙盒Web服务
3. 在WP7应用中放置一个浏览器控件，并为该控件添加事件BrowserControl_Navigated
4. 为我们自己的网站(如string.Format("http://localhost:62744/PaymentGateway/ExpressCheckout.aspx?ItemName={0}&Number={1}&Desc={2}&ItemPrice={3}&ItemUrl={4}", ItemName, ItemNumber, ItemDescription, ItemPrice, ItemUrl).Replace(" ", "+");
)创建网址
5. 使用我们的WP7应用代码BrowserControl.Navigate(new Uri(url));
调用网站
6. 完成付款后，贝宝服务会将应用重定向到成功网址，否则我们将重定向到失败网址
7. 在BrowserControl_Navigated事件中添加条件以检查贝宝的成功和失败网址

8. 如果条件成功，请导航到WP7中的成功页面

1. Create a website which will take item prices/details in querystring
2. implement ExpressCheckout in that website only. I've implemented using paypal Sandbox Web service
3. Place a browser control in the WP7 app and add an event BrowserControl_Navigated for that control
4. Create the Url for for our own website like string.Format("http://localhost:62744/PaymentGateway/ExpressCheckout.aspx?ItemName={0}&Number={1}&Desc={2}&ItemPrice={3}&ItemUrl={4}", ItemName, ItemNumber, ItemDescription, ItemPrice, ItemUrl).Replace(" ", "+");
5. Call the Website in our WP7 app code BrowserControl.Navigate(new Uri(url));
6. After completion of the payment paypal service will redirect the app to a success url which we mentioned otherwise redirect to failure url
7. in the BrowserControl_Navigated event add conditions to check the paypal success and failure urls

8. if the condition success navigate to success page in WP7

if (BrowserControl.Source.ToString().Contains( "http://localhost:62744/PaymentGateway/Success.html"))
     NavigationService.Navigate(new Uri("/Success.xaml", UriKind.Relative));

更新:

以上代码会将页面重定向到PayPal移动页面，在外观上不如iOS登录页面好.我们可以使用Windows Phone 7中的一个小技巧来获取PayPal iOS页面

通过更改浏览器的标题(客户端的用户代理)，将为我们提供PayPal iPhone页面

By changing the headers(user-agent of client) of the browser will give us the PayPal iPhone page

像下面一样

  string header = "User-Agent:Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8B117 Safari/6531.22.7";

  string url = string.Format("http://10.11.32.211:88/PaymentGateway/ExpressCheckout.aspx?ItemName={0}&Number={1}&Desc={2}&ItemPrice={3}&ItemUrl={4}", ItemName, ItemNumber, ItemDescription, ItemPrice, ItemUrl).Replace(" ", "+");

  BrowserControl.IsScriptEnabled = true;

  BrowserControl.Navigate(new Uri(url),null, header);
