获取token，参数值错误，直接抛异常，而且异常信息不是json，如何解析code值，代码如下

[Tim-Zhang]

Map<String, Object> appAccessTokenBody = new HashMap<>();
appAccessTokenBody.put("app_id", Constant.FeiSuOpenAiAppId);
appAccessTokenBody.put("app_secret", Constant.FeiSuOpenAiAppSecret);

    try {
        RawResponse resp = getClient().post(Constant.FeiShuAppAccessToken, appAccessTokenBody, AccessTokenType.Tenant);

        // 处理结果
        System.out.println(resp.getStatusCode());
        System.out.println(Jsons.DEFAULT.toJson(resp.getHeaders()));
        System.out.println(new String(resp.getBody()));
        System.out.println(resp.getRequestID());
    } catch (Exception e) {
        e.printStackTrace();
    }
