如何从一个WCF REST方法返回一个自定义HTTP状态code？ [英] How can I return a custom HTTP status code from a WCF REST method?

问题描述

如果出现错误的WCF REST调用，如所请求的资源是找不到的，我怎么能与HTTP响应code打（它设定成类似HTTP 404为例），在我的OperationContract的方法？

If something goes wrong in a WCF REST call, such as the requested resource is not found, how can I play with the HTTP response code (setting it to something like HTTP 404, for example) in my OperationContract method?

推荐答案

有一个<一个href="http://msdn.microsoft.com/en-us/library/system.servicemodel.web.weboperationcontext.aspx"><$c$c>WebOperationContext您可以访问，它有一个<一个href="http://msdn.microsoft.com/en-us/library/system.servicemodel.web.weboperationcontext.outgoingresponse.aspx"><$c$c>OutgoingResponse类型的财产<一href="http://msdn.microsoft.com/en-us/library/system.servicemodel.web.outgoingwebresponsecontext.aspx"><$c$c>OutgoingWebResponseContext其中有一个<一href="http://msdn.microsoft.com/en-us/library/system.servicemodel.web.outgoingwebresponsecontext.status$c$c.aspx"><$c$c>Status$c$c属性可设置

There is a WebOperationContext that you can access and it has a OutgoingResponse property of type OutgoingWebResponseContext which has a StatusCode property that can be set.

WebOperationContext ctx = WebOperationContext.Current;
ctx.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.OK;
