Question

我有一个托管在IIS7中的WCF服务，这个服务只是另一个服务的包装器，所以它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请求并返回数据，当我发送第二个请求时，我得到以下错误：请你在这里分享一些问题。

这是一项REST服务吗？一个SOAP服务?? 我认为您没有在服务中处理异常，因此您从IIS获取默认响应，这是一个网页。

您应该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，您应该尝试自定义处理服务上的传入请求。

或许这可以帮助Specified argument was out of the range of valid values. Parameter name: site

来自WCF服务的响应不一致
