WCF服务的响应不一致

Question

I have a WCF service that is hosted in IIS7, this service is just a wrapper of another service, so what it does it calls the actual service then return a response which is then passed on to the client. 我有一个IIS7中托管的WCF服务，该服务只是另一个服务的包装，因此它调用实际的服务，然后返回响应，然后将响应传递给客户端。 The issue that I'm having is that I send a request and it returns data, when I send another request with the second then I get the below error: Please will you share some light on what could be a problem here. 我遇到的问题是我发送了一个请求，并返回了数据，当我在第二个请求中发送了另一个请求时，出现以下错误：请您就此可能出现的问题分享一些看法。

It's a REST service? 这是REST服务吗？ A SOAP service?? SOAP服务？ I think that you're not handling the exception in the service, so you're getting the default response from IIS, which is a web page. 我认为您没有在服务中处理异常，因此您从IIS（它是一个网页）获取默认响应。

You should handle the exception in the service and return an object (or XML) containing the exception details. 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）。

If it's an invocation error, you should try to custom handle incoming requests on the service. 如果是调用错误，则应尝试自定义处理服务上的传入请求。

Or maybe this could help Specified argument was out of the range of valid values. 也许这可以帮助指定的参数超出有效值范围。 Parameter name: site 参数名称：site
