Verify an App Store Transaction Receipt "Apple server verifies the validity of a transaction receipt for an app shop"

Transferred from: http://blog.csdn.net/saindy5828/article/details/6414014

1, from the transaction transactionreceipt attribute received data, and Base64 encoding;

2, create JSON object, dictionary format, single key value pair, the key name is "Receiptdata", the value is the last encoded data, the effect:

{"Receipt-data": "Base64 Data after encoding}"

3. Send an HTTP POST request to send the data to the app Store with the address: Https://buy.itunes.apple.com/verifyReceipt

4. The return value of the APP store is also a JSON-formatted object, including two key-value pairs:

{
"Status": 0,
"Receipt": {...}
}
Description

If the value of status is 0, it means that the receipt is valid, otherwise it is invalid.

The authentication can also take the HTTP protocol: HttpClient, download httpcomponents-client, and then import several jar packages in lib.

This is also a way to no longer make redundant explanations. The so-called roads Pass "apples".
