WCF Web API preview 6: No 'MediaTypeFormatter' is available

由 点点圈 提交于 2019-12-06 13:15:13

Their HTTP responses have the Content-Type header set to text/plain. It appears that having the response Content-Type set to text/plain is causing problems. I'm making the request to the service as follows: Task<HttpResponseMessage> result = client.PostAsync(apiEndpoint, new ObjectContent(typeof (LeaveAccrualRequest), request)); Using Fiddler, I can see the request go to the service and an appropriate, expected response come back. However

Uploading files WCF Web API Endpoint

由 a 夏天 提交于 2019-12-06 12:13:19

In the overrides you will be given the NetworkStream when the HTTPClient is ready to receive the stream. If you are asking about the server side, then you can simply get hold of the HTTPRequestMessage and

How does WCF WebApi map a request URI to the appropriate service type / operation?

由 徘徊边缘 提交于 2019-12-06 12:07:05
问题 How does WCF REST (and WCF WebApi) map a Uri to the correct service endpoint? Within the context of WCF WebApi Preview 4: Inside a custom delegating channel, I would like to find the associated route prefix or service Type based on the incoming HttpRequestMessage.RequestUri. So for instance, RouteTable.Routes.MapServiceRoute<ManagersResource>("employees/managers", config); RouteTable.Routes.MapServiceRoute<EmployeesResource>("employees", config); Say a request comes in for http://server
