Question

我正在创建WCF服务，并且在我将其连接到WinForms客户端时工作正常。但我想通过浏览器访问它。有些方法工作正常，但是当我尝试发回包含多个对象的对象时，它会返回错误消息＆＃34;重置连接＆＃34; ...我试图测试我的服务ARC和JQuery Ajax，以及我收到同样错误的所有情况。

我差点忘了告诉你，只有在我创建一个Period属性的实例时才会出现这个问题。如果我将对象清除，我就不会有任何问题。

我与您分享了我根据原始代码进行的测试。我希望你能帮助我。

Answer 1

我刚刚在我正在使用的WCF服务中发现了一段相同的问题，即（现在）使用webHttpBinding（对于REST客户端）。罪魁祸首是财产＆＃34; IsReference = true＆＃34;在DataContract类中。我需要将该标志设置为TRUE，因为对象图包含循环引用;这样返回的响应比真实对象序列化的字节少得多。

我不知道为什么这适用于SOAP和其他绑定但不适用于webHttpBinding，但由于我需要添加REST支持，因此当返回一个IsReference = true的DataContract类时，服务停止工作。

我的临时解决方案是创建另一个具有与原始属性相同的属性的类，但没有IsReference属性。我需要进一步调查，但与此同时，我希望这会有所帮助。
