java - 使用 QBOVendorService 的 NPE

Question

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

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

其中上下文是有效的 PlatformSessionContext。我知道平台 session 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，就像我的 vService 为空一样。如果初始化 QBOVendorService 失败，我不应该收到错误吗？由于 intuit 开发者论坛已关闭，是否有一个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片段。替换您的 OAuth token 和 relamId。应该可以正常工作。

    public static void main(String args[]) {
        PlatformSessionContext context = getPlatformContext();
        CodegenStubVendorall testObj = new CodegenStubVendorall(context);
        testObj.testAdd();
    }

    public static PlatformSessionContext getPlatformContext() {

        String accesstoken = "rplce_your_application_token";
        String accessstokensecret = "rplce_your_application_token";
        String appToken = "rplce_your_application_token";
        String oauth_consumer_key = "rplce_your_application_token";
        String oauth_consumer_secret = "rplce_your_application_token";
        String realmID = "123456";
        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 token 并检查创建 Vendor API 端点。

请让我知道进展如何。
