如何向 WCF 中的请求添加授权标头?

How can I add authorization header to the request in WCF?(如何向 WCF 中的请求添加授权标头?)

问题描述

我正在开发一个 Windows 窗体应用程序，并且需要调用一个 WCF 服务.在将请求发送到服务之前，我需要向请求添加标头(授权 - 自定义).我也有一个自定义检查器类.我尝试了以下方法，但不知何故未调用该服务，它返回异常.

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;
}

我也试过这样最简单的方法:

I also tried simplest way like this one:

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

但是一样，添加了授权头但没有到达服务，我怎么知道服务收到了什么头?当我在请求中手动添加这样的标头时(在运行之前)，我使用了 SOAP UI 并且服务响应良好.

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

最简单的方法是在客户端添加:

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);
     }
}

并在服务器端检索它:

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