SOAP Header

要添加 SOAP 标头，请使用以下代码客户端:

To add a SOAP header, use the following code client-side:

using (OperationContextScope scope = new OperationContextScope((IContextChannel)channel))
{
    MessageHeader<string> header = new MessageHeader<string>("MyHttpHeaderValue");
    var untyped = header.GetUntypedHeader("User-Auth", ns);
    OperationContext.Current.OutgoingMessageHeaders.Add(untyped);

    // now make the WCF call within this using block
}

然后，服务器端，使用:

MessageHeaders headers = OperationContext.Current.IncomingMessageHeaders;
string identity = headers.GetHeader<string>("User-Auth", ns);

注意.ns 是头部 XML 元素的命名空间 URI.

HTTP 标头

添加一个 Http 头:

To add an Http header:

// Add a HTTP Header to an outgoing request 
HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();
requestMessage.Headers["MyHttpHeader"] = "MyHttpHeaderValue";
OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;

并抓取它服务器端

IncomingWebRequestContext request = WebOperationContext.Current.IncomingRequest; 
WebHeaderCollection headers = request.Headers; 
Console.WriteLine(request.Method + " " + request.UriTemplateMatch.RequestUri.AbsolutePath); 

foreach (string headerName in headers.AllKeys)
{ 
    Console.WriteLine(headerName + ": " + headers[headerName]); 
}
