关于Google Play Billing结算服务,付款后如何将google的订单与自己服务器的订单数据相关联? 5C

公司最近有海外的业务,打算接入google支付,不过现在新版的接入跟以往有所不同,关于透传参数这块改了。
以前的支付是 AIDL ,客户端先在服务端下单,传递给客户传订单号,客户端在支付的时候传递给谷歌,然后支付回来,谷歌透传给客户端,客户端再回调给服务端订单id。但是现在新版,这个透传参数反而是支付完了之后, 客户端要去谷歌确认支付完成订单的时候,才去设置这个参数。
这是原话。
您可以将任意字符串或开发人员有效负载附加到购买中。但是,请注意,只有在确认购买或消费后才能附加开发人员有效负载。这与AIDL中的开发人员有效负载不同,在AIDL中,开发人员有效负载可以在购买时指定启动购买流程。
现在客户端支付回调给服务端的时候不知道关联了?有哪位大大知道,麻烦讲解下,感激不尽!!

您可以将任意字符串或开发人员有效负载附加到购买中。
也就是你可以自己生成一个流水号,比如用2020031912080001这样的,传过去。然后确认购买返回后,再关联给这个流水

学步大师 回复tb1230123: 你解决了这个问题没,它透传字段没了。掉单后,订单号跟商品信息关联不了。头痛

tb1230123 新版的这个跟旧版不一样,它是在你支付发货完了之后,对该订单进行确认已购买的时候进行设置的

google play billing 服务器效验

我在应用内使用google play的支付功能,前面一路正常,结果卡在了服务器效验上,我把google传给我的数据进行效验一直不成功,google传递过来的数据绝对超过了rsa加密的长度,是有做特殊处理吗?

我们如何使用Google Play服务进行后端服务器验证?

<div class="post-text" itemprop="text"> <p>I was following these articles: <a href="http://android-developers.blogspot.com/2013/01/verifying-back-end-calls-from-android.html" rel="nofollow">Verifying Back-End Calls from Android Apps</a> and <a href="http://www.google.com/events/io/2011/sessions/evading-pirates-and-stopping-vampires-using-license-verification-library-in-app-billing-and-app-engine.html" rel="nofollow">Stopping Vampires using License Verification Library (from 24:57 to 25:34)</a> to implement an In-App Purchase verification system for our Android apps.</p> <p>I am a bit confused about how this works end-to-end and what we can assume about the generated token from calling <a href="http://developer.android.com/google/play-services/auth.html#obtain" rel="nofollow">GoogleAuthUtil.getToken()</a> with the first email address found--when AccountManager returns more than one account. My questions are as follows:</p> <ol> <li><p>Should we assume that any e-mail address used by the user to buy our app will generate the same token (i.e., same user + app ==&gt; same token)?</p></li> <li><p>If the answer to question 1 is no, is there a way to launch in-app purchase for a particular account/email?</p></li> <li><p>It looks like Google is picking the first e-mail address returned by AccountManager for its in-app purchase dialog. Can we assume that this won't be changed by the user after in-app purchase dialog is launched? How do we find out if this changed after the in-app purchase returns?</p></li> <li><p>What should we store in our database to identify this user? Is email address and/or token allowed? When does the token expire?</p></li> <li><p>The java-client library looks very promising and powerful at first read. But, a number of things remains confusing. Is there an article that describes the end-to-end scenario--from an app initiating a call to a back-end server through launching the in-app purchase dialog, getting the result and closing with commits on the server?</p></li> <li><p>What articles are the most useful for accomplishing this on Android?</p></li> </ol> <p>The main issue we are trying to solve is to to get the full picture.</p> <p>We've gotten the idea that we can avoid requiring userid/password by using the java client features and using tokens. We have registers our project (both the web app and android app on the same project) per the instructions for Google API Console. We have the php java-client for Google Play Service on our back-end server. We got our Android app to generate a token using the first email address and then call the in-app purchase dialog and handle the user response at the end of the dialog. We've got the parts. Now, we need to glue everything together. We are at the point of integrating with the back-end server. E.g., What is Redirect URi supposed to point to in our server? We've got a php url that we do http post messages to for our server app. We've included the code example for Google API client example--with client-id, secret, simple api key, etc. filled in--as an include to our php. But, what should we put in the redirect uri (we are missing a usage instruction for the example code)?</p> <p>Also, we want to avoid having the e-mail used for the in-app purchase be different from what we log on our server database as the address the user used to buy our app; if the address is the correct thing to track, we want it to be the same as what was used for the purchase. This could be frustrating for our user if we make this mistake and prevent them from the features they paid for. We don't want to make this mistake and need some clarification on how Google Play Service works. If we initiated the server part of the workflow to get app Nonce / Payload / Credentials for the first e-mail address on the Android device, we would want that address to be used throughout the workflow. If the user changed this along the line, we want to be aware of this and gracefully recover. So far the articles have been helpful but incomplete. Any insight/suggestion is appreciated.</p> </div>

Paypal定期付款没有结算周期[关闭]

<div class="post-text" itemprop="text"> <p>I want to implement paypal recurring payment without any specific billing cycle. Consider this scenario: customer buys a service from my account which is charged on usage basis for example downloading content from site.
