java - Apple 购买：使用 Rest 模板验证收据

Question

我必须实现一个 API，旨在使用 Rest 模板通过 Apple 服务器验证收据。但是，我总是从https://sandbox.itunes.apple.com/verifyReceipt收到状态代码 21002

 public void verifyReceipt(Purchase purchase) {

    String uri = "https://sandbox.itunes.apple.com/verifyReceipt";
    String receipt = new String(Base64.getEncoder().encode(purchase.getReceipt().getBytes()));

    Map<String, String> params = new HashMap<>();
    params.put("receipt-data", receipt);
    params.put("password", "secret");

    Gson gson = new Gson();
    String json = gson.toJson(params);
    RestTemplate restTemplate = new RestTemplate();
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity<String> request = new HttpEntity<>(json, headers);
    ResponseEntity<String> response = restTemplate.exchange(uri, HttpMethod.POST, request ,String.class);
....

}

任何的想法 ？

Answer 1

什么是Purchase班级？客户端（iOS 应用程序）发送到我们服务器端的收据数据应该已经是 base64 编码的。
