使用 QBOVendorService 的 NPE

Question

我正在尝试使用 QBOVendorService 查询供应商，但没有运气。 我正在按如下方式创建服务：

       QBOVendorService vService = QBServiceFactory.getService(context, QBOVendorService.class);

上下文是有效的 PlatformSessionContext。我知道平台会话上下文很好，因为我可以使用它获取有关用户的信息。当我尝试时

           vService.addVendor(context, vendor);

我最终得到一个 NPE，比如我的 vService 为空。如果 QBOVendorService 失败，我不应该得到一个错误初始化吗？由于 intuit 开发者论坛已关闭，有没有好地方可以找到更多使用此功能的示例？

我正在分享一个示例代码 sn-p。替换您的 OAuth 令牌和 relamId。它应该可以正常工作。

    public static void main(String args[]) {

        String dataSource = "QBO";

        PlatformServiceType serviceType;
        if (dataSource.equalsIgnoreCase("QBO")) {
            serviceType = PlatformServiceType.QBO;
        } else {
            serviceType = PlatformServiceType.QBD;
        }

        final OAuthCredentials oauthcredentials = new OAuthCredentials(
                oauth_consumer_key, oauth_consumer_secret, accesstoken,
                accessstokensecret);

        final PlatformSessionContext context = new PlatformSessionContext(
                oauthcredentials, appToken, serviceType, realmID);

        return context;
    }
}

您可以尝试使用 ApiExplorer 工具来验证您的 OAuth 令牌并检查创建供应商 API 端点。

请告诉我进展如何。
