WCF 服务的响应不一致

本文关键字：不一致 响应 服务 WCF | 更新日期: 2023-09-27 18:35:18

我有一个在 IIS7 中承载的 WCF 服务，此服务只是另一个服务的包装器，因此它的作用调用实际服务，然后返回一个响应，然后传递给客户端。我遇到的问题是我发送了一个请求并返回数据，当我用第二个请求发送另一个请求时，我收到以下错误： 请您分享一些关于这里可能出现的问题的见解。

WCF 服务的响应不一致

这是一个 REST 服务？一个肥皂服务？？我认为您没有处理服务中的异常，因此您从 IIS（一个网页）获得默认响应。

应在服务中处理异常，并返回包含异常详细信息的对象（或 XML）。

如果是调用错误，则应尝试自定义处理服务上的传入请求。

或者这可能有助于指定的参数超出了有效值的范围。参数名称：站点
