IAP Process
The IAP process is divided into two types:
One is to purchase and verify directly with Apple's servers,
The other is to assume that the server is validating. Because the domestic network connection Apple server verification is very slow, but also to prevent hackers to forge proof of purchase, the general practice is to set up a server to verify.
Let's take a look at the differences between the two ways:
Using the Apple server
Set up your own server
The important thing here is to talk about the service side of this piece of the verification process because it involves verifying legitimacy. 1, first get the client's payment Receiptdata and transaction information 2, the service side through the Receiptdata through to the Apple Server Post data Verification 3, the service end of the Apple server Response data processing and verifying the legitimacy of the order. 3. If the order is lawful, the order will be processed accordingly.
