我该如何授权头添加到WCF的要求？ [英] How can I add authorization header to the request in WCF?

问题描述

我工作的一个Windows窗体应用程序，有需要调用WCF服务。我需要一个头（授权 - 自定义）之前添加它发送到服务请求。我有一个自定义类检查为好。我尝试以下，但该服务不叫，不知何故，它返回一个例外。

I'm working on a Windows Form application and there's a WCF service that needs to be called. I need to add a header (authorization - custom) to the request before it's sent to the service. I have a custom inspector class as well. I tried the following but the service is not called, somehow, and it returns an exception.

public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
    MessageHeader header = MessageHeader.CreateHeader("Authorization", "", "Basic Y19udGk6Q29udGlfQjNTVA==");
    OperationContext.Current.OutgoingMessageHeaders.Add(header);
    HttpRequestMessageProperty httpRequestProperty = new HttpRequestMessageProperty();
    httpRequestProperty.Headers.Add("Authorization", "Basic Y19udGk6Q29udGlfQjNTVA==");
    httpRequestProperty.Headers.Add(HttpRequestHeader.UserAgent, "Continental");
            OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;
    sentMessages.Add(request.ToString());
    return null;
}

我也试过像这样的简单的方法：

I also tried simplest way like this one:

MessageHeader header = MessageHeader.CreateHeader("Authorization", "", "Basic Y19udGk6Q29udGlfQjNTVA==");
request.Headers.Add(header);

但它是相同的，授权头被添加，但它没有达到的服务，我怎么能知道是由服务接收什么头？我用SOAP UI和服务响应很好，当我在请求中手动添加这样的标题（运行前）。

but it's the same, authorization header is added but it does not reach the service, how can I know what header is received by the service? I used SOAP UI and service responds well when I add such a header manually in the request (before running).

推荐答案

最简单的方法是将添加在客户端

using (MyServ.ServiceClient proxy = new MyServ.ServiceClient())
{
     using (new System.ServiceModel.OperationContextScope(proxy.InnerChannel))
     {
         MessageHeader head = MessageHeader.CreateHeader("Authorization", "http://yournamespace.com/v1", data);
         OperationContext.Current.OutgoingMessageHeaders.Add(head);
     }
}

和获取它在服务器端

string  auth = OperationContext.Current.IncomingMessageHeaders.
GetHeader<string>("Authorization", "http://mynamespace.com/v1");
