i'm desperately trying to validate a receipt for in-app in a futur IOS application written with Swift, IOS8.1 I'm using the Alamofire framework to compensate a bug in NSURLConnection for swift but still not having any return from the Apple Server. func checkReceipt(data:NSData) { let ITMS_PROD_VERIFY_RECEIPT_URL = "https://buy.itunes.apple.com/verifyReceipt" let ITMS_SANDBOX_VERIFY_RECEIPT_URL = "https://sandbox.itunes.apple.com/verifyReceipt" let base64String = self.base64forData(data) if base64String != nil { let decodedData = NSData(base64EncodedString: base64String!, options:

/*注意事项： 1.沙盒环境测试appStore内购流程的时候，请使用没越狱的设备。 2.请务必使用真机来测试，一切以真机为准。 3.项目的Bundle identifier需要与您申请AppID时填写的bundleID一致，不然会无法请求到商品信息。 4.如果是你自己的设备上已经绑定了自己的AppleID账号请先注销掉,否则你哭爹喊娘都不知道是怎么回事。 5.订单校验 苹果审核app时，仍然在沙盒环境下测试，所以需要先进行正式环境验证，如果发现是沙盒环境则转到沙盒验证。 识别沙盒环境订单方法： 1.根据字段 environment = sandbox。 2.根据验证接口返回的状态码,如果status=21007，则表示当前为沙盒环境。 苹果反馈的状态码： 21000App Store无法读取你提供的JSON数据 21002 订单数据不符合格式 21003 订单无法被验证 21004 你提供的共享密钥和账户的共享密钥不一致 21005 订单服务器当前不可用 21006 订单是有效的，但订阅服务已经过期。当收到这个信息时，解码后的收据信息也包含在返回内容中 21007 订单信息是测试用（sandbox），但却被发送到产品环境中验证 21008 订单信息是产品环境中使用，但却被发送到测试环境中验证 */ 开发内购功能，首先需要一个开发者账号，在 App store connect ->

用设计模式来替代if-else 前言 物流行业中，通常会涉及到EDI报文(XML格式文件)传输和回执接收，每发送一份EDI报文，后续都会收到与之关联的回执（标识该数据在第三方系统中的流转状态）。这里枚举几种回执类型： MT1101、MT2101、MT4101、MT8104、MT8105、MT9999 ，系统在收到不同的回执报文后，会执行对应的业务逻辑处理。当然，实际业务场景并没有那么笼统，这里以 回执处理为演示案例 模拟一个回执类 @Data public class Receipt { /** * 回执信息 */ String message; /** * 回执类型(`MT1101、MT2101、MT4101、MT8104、MT8105、MT9999`) */ String type; } 模拟一个回执生成器 public class ReceiptBuilder { public static List<Receipt> generateReceiptList(){ //直接模拟一堆回执对象 List<Receipt> receiptList = new ArrayList<>(); receiptList.add(new Receipt("我是MT2101回执喔","MT2101")); receiptList.add(new Receipt("我是MT1101回执喔",

For example, he can send something like: M1VYXX7VX7 (as written in his purchases list in appstore) and ask to return his purchase (may be he had deleted his app accidentally), But when I get order information inside of my code (through SKPaymentTransaction ) I have no access to that identifier. Then only ID i have looks like: 1000000020706713. So is there any ways to validate that purchase ID using information which was sent to me by app store? Thanks. 回答1: Read

I have been trying to implement receipt validation in my spritekit game. I have been following various tutorial and basically ended up with this code enum RequestURL: String { case production = "https://buy.itunes.apple.com/verifyReceipt" case sandbox = "https://sandbox.itunes.apple.com/verifyReceipt" case myServer = "my server address" } enum ReceiptStatusCode: Int { // Not decodable status case unknown = -2 // No status returned case none = -1 // valid status case valid = 0 // The App Store could not read the JSON object you provided. case JSONNotReadable = 21000 // The data in the receipt
