Service业务处理

//第零步：前端授权处理，传identityToken给到后端

//第一步：验证identityToken

//第二步：对identityToken解码,获取苹果账号的openId(唯一标识)

   public JSONObject appleLogin(String identityToken) throws Exception {
        JSONObject jsonObject = new JSONObject();
        log.info("苹果 identityToken,{}", identityToken);
        //第一步：验证identityToken
        if (!AppleUtils.verify(identityToken)) {
            throw new Exception("授权验证失败");
        }
        log.info("苹果授权验证成功！");
        //第二步：对identityToken解码
        JSONObject json = AppleUtils.parserIdentityToken(identityToken);
        if (json == null) {
            throw new Exception("授权解码失败");
        }
        log.info("返回认证信息 ：{}", json);
        String openId = (String) json.get("sub");
        if (StringUtils.isBlank(openId)) {
            throw new Exception("未获取到openId信息");
        }
        //TODO 获取到苹果的 openId 后，做自己的业务逻辑处理
