IOS购买订阅通知信息解析说明Java

1、IOS 接受通知信息，及对应参数信息 
JSONObject iosNotification(@RequestBody JSONObject request) 

2、获取加密需要解密的字符串

String signedPayLoad= request.getString("signedPayload");

3、对JWT密文进行解析

JSONObject jsonObject = ApplePayUtil.verifyAndGet(signedPayLoad);

4、对最近一次交易的详细信息进行解析

ApplePayUtil.verifyAndGet(signedTransactionInfo);

5、对关于未来续订的信息进行解析

ApplePayUtil.verifyAndGet(signedRenewalInfo);

6、解析密文方法：

public static JSONObject verifyAndGet(String jws) throws CertificateException {DecodedJWT decodedJWT = JWT.decode(jws);// 拿到 header 中 x5c 数组中第一个String header = new String(java.util.Base64.getDecoder().decode(decodedJWT.getHeader()));String x5c = JSONObject.parseObject(header).getJSONArray("x5c").getString(0);// 获取公钥PublicKey publicKey = getPublicKeyByX5c(x5c);// 验证 tokenAlgorithm algorithm = Algorithm.ECDSA256((ECPublicKey) publicKey, null);try {algorithm.verify(decodedJWT);} catch (SignatureVerificationException e) {throw new RuntimeException("签名验证失败");}// 解析数据return JSONObject.parseObject(new String(java.util.Base64.getDecoder().decode(decodedJWT.getPayload())));
}
