 iAP服務(wù)端驗(yàn)證，網(wǎng)絡(luò)上介紹的東西不多，找很很久才找到蘋果的官方文檔，記錄下來。

Verifying an App Receipt

Communication with the App Store is structured as JSONdictionaries, as defined in RFC 4627. To verify the receipt,perform the following steps:

1. Retrieve the receipt data and base64 encode it (using the RFC 4648form of base64). Use the appStoreReceiptURL methodof NSBundle to locate theapp’s receipt, and then read the entire file.

   If the appStoreReceiptURL methodis not available, you can fall back to the value of atransaction's transactionReceipt property forbackward compatibility.

2. Create a JSON object with a single key named receipt-data whosevalue is the base64-encoded receipt data. Your JSON object shouldlook like this:

   {

   "receipt-data" : "(receipt bytes here)"

   }

3. Send the JSON object to the App Store using an HTTP POST request.The URL for the store is https://buy.itunes.apple.com/verifyReceipt.

4. The response received from the App Store is a JSON object with thekeys status and receipt.(When validating an auto-renewable subscription, the responsecontains additional keys, as described in “Verifyingan Auto-Renewable Subscription Receipt”). Itshould look something like this:

   {

   "status" : 0,

   "receipt" : { (receipt here) }

   }

   If the value of the status keyis 0,this is a valid receipt. If the value is anything otherthan 0,this receipt is invalid.

The value of the receipt keyis a JSON object that contains the receipt’s fields. Forinformation about the fields in a receipt,see “ReceiptFields.”

沙盒測(cè)試的時(shí)候地址是：https://sandbox.itunes.apple.com/verifyReceipt 

下面這個(gè)差不多就是上面官方文檔的中文介紹版本：

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

 同時(shí)還提供了JAVA版的代碼：

public int verifyReceipt( byte[] receipt){
      int status = -1;

       //This is the URL of the REST webservice in iTunes App Store
       URL url = new URL("https://buy.itunes.apple.com/verifyReceipt");

       //make connection, use post mode
       HttpsURLConnection connection = (HttpsURLConnection)url.openConnection();
       connection.setRequestMethod("POST");
       connection.setDoOutput(true);
       connection.setAllowUserInteraction(false);

       //Encode the binary receipt data into Base 64
       //Here I'm using org.apache.commons.codec.binary.Base64 as anencoder, since commons-codec is already in Grails classpath
       Base64 encoder = new Base64();
       String encodedReceipt = newString(encoder.encode(receipt));

       //Create a JSON query object
       //Here I'm using Grails'org.codehaus.groovy.grails.web.json.JSONObject
       Map map = new HashMap();
       map.put("receipt-data", encodedReceipt);
       JSONObject jsonObject = new JSONObject(map);

       //Write the JSON query object to the connection output stream
       PrintStream ps = newPrintStream(connection.getOutputStream());
       ps.print(jsonObject.toString());
       ps.close();

       //Call the service
       BufferedReader br = new BufferedReader(newInputStreamReader(connection.getInputStream()));
       //Extract response
       String str;
       StringBuffer sb = new StringBuffer();
       while ((str = br.readLine()) != null) {
           sb.append(str);
           sb.append("/n");
       }
       br.close();
       String response = sb.toString();

       //Deserialize response
       JSONObject result = new JSONObject(response);
      status = result.getInt("status");
       if (status == 0) {
           //provide content
       } else {
           //signal error, throw an exception, do your stuff honey!
       }

       return status ;

   }
