IsOneWay WCF REST服务上的WebOperationContext.Current.IncomingRequest.Headers为空 [英] WebOperationContext.Current.IncomingRequest.Headers Empty on an IsOneWay WCF REST service

问题描述

I'm experiencing an unexpected behavior within a WCF REST service that is marked as IsOneWay.

我正在将参数添加到客户端的请求标头中，在服务器端，我试图通过 WebOperationContext.Current.IncomingRequest.Headers  为空.

I am adding params to the request headers from the client, on the server side I'm trying to access these via WebOperationContext.Current.IncomingRequest.Headers. On a standard service method, the Headers collection is filled and has the headers that I have set. When I change the method to IsOneWay however, WebOperationContext.Current.IncomingRequest.Headers is empty.

// Works
[WebInvoke(UriTemplate = "MyMethod/{id}")] 
public void MyMethod(string id, object data) 
{ 
   WebOperationContext.Current.IncomingRequest.Headers.Count; // > 1
}

// Fails
[WebInvoke(UriTemplate = "MyMethod/{id}")] 
[OperationContract(IsOneWay = true)] // <-- This is the issue
public void MyMethod(string id, object data) 
{ 
   WebOperationContext.Current.IncomingRequest.Headers.Count; // 0
}

Any idea how I can still access the headers with IsOneWay set?

推荐答案

客户端发送的标头是?与提琴手确认.

are the headers sent by the client? check with fiddler.
