QuickBooks不适用于Google App Engine

问题描述 投票：1回答：2

我试图通过运行这个简单的代码从谷歌应用引擎在线连接到quickbooks：

OAuthCredentials oauthcredentials = new OAuthCredentials(consumerKey, consumerSecret, accessToken, accessTokenSecret);

PlatformSessionContext context = new PlatformSessionContext(oauthcredentials, appToken, PlatformServiceType.QBO, realmID);

QBCustomerService customerService = QBServiceFactory.getService(context, QBCustomerService.class);

QBIdType idType = new QBIdType(context);

idType.setValue("2");

QBCustomer c = customerService.findById(context, idType);

System.err.println(c.getName());

它总是抛出这个错误：

在我的代码中，com.xyz.server.tasks.SyncCustomerTask.runMethod(SyncCustomerTask.java:85)是findbyId("2")行。有什么建议如何解决这个问题？任何帮助都会非常贴切

AppEngine仅提供有限的Socket API。特别是，你不能使用大多数getsockopt / setsockopt调用，在你的情况下抛出错误（setTcpNoDelay(..)）。

QuickBooks SDK似乎是封闭源代码，因此没有办法解决它。

更新：

从GAE Java SDK 1.8.1。开始，可以使用套接字选项方法：它们是无操作的，但它们不会像过去那样抛出异常：

The Sockets API now allows client code to call get/set options against sockets. Previously, calls raised "Not Implemented" exceptions. When java.net.Socket.get<option>() is called, a mock value is returned, calls to set<option>() will be silently ignored.

我很感谢你发布了这个问题。除了我用Go语言而不是Java开发我的谷歌应用程序之外，我一直在用相同的问题敲打墙头几天。但我做了它的工作！我希望我的解决方案也能帮到你。基本上，我没有使用套接字服务，而是使用URL Fetch服务，这里记录了Java：https://developers.google.com/appengine/docs/java/urlfetch/

我对你原帖中的一些细节很不了解（我没有用Java开发，也不熟悉QBServiceFactory和OAuthCredentials）。所以我不确定你对它如何实际向QB发送请求有多少控制权。但最糟糕的情况是，我认为您可以编写自己的函数来替换QBServiceFactory（我必须在Go中执行），如果您确保使用URL Fetch服务而不是套接字，那么您可能会更好运气。

正如我所说，我非常感谢你的问题，因为我不认为我会偶然发现我的答案，谢谢！
