如何读取HTTP请求头中的一个WCF Web服务？ [英] How to read HTTP request headers in a WCF web service?

问题描述

在一个WCF Web服务，一个人如何读取HTTP / HTTPS请求头？在这种情况下，我试图确定原始URL主机所使用的客户端。这可能是在X - 转发，主机头从负载均衡器，或者在主机头，如果是直接框。

我试过 OperationContext.Current.IncomingMessageHeaders.FindHeader ，但我认为这是在看SOAP头，而不是HTTP标头。

那么，如何读取HTTP头？当然，这是一个简单的问题，我缺少明显的东西。

编辑 - @ sinfere的回答几乎正是我需要的。为了完整起见，这里是我结束了：

  IncomingWebRequestContext请求= WebOperationContext.Current.IncomingRequest;
WebHeaderCollection头= request.Headers;
字符串主机= NULL;如果（标题[X  - 转发，主机]！= NULL）
    主机=标题[X  - 转发，主机];
否则，如果（标题[HOST]！= NULL）
    主机=标题[主机];
其他
    主机= defaulthost; //从配置值设置
 

解决方案

尝试WebOperationContext.Current.IncomingRequest.Headers

我用下面的codeS看到所有的标题

  IncomingWebRequestContext请求= WebOperationContext.Current.IncomingRequest;
WebHeaderCollection头= request.Headers;Console.WriteLine（--------------------------------------------- ----------）;
Console.WriteLine（request.Method ++ request.UriTemplateMatch.RequestUri.AbsolutePath）;
的foreach（在headers.AllKeys串headerName）
{
  Console.WriteLine（headerName +：+报头[headerName]）;
}
Console.WriteLine（--------------------------------------------- ----------）;
 

In a WCF web service, how does one read an HTTP/HTTPS request header? In this case, i'm trying to determine the original URL host the client used. This might be in the X-Forwarded-Host header from a load balancer, or in the Host header if it's direct-box.

I've tried OperationContext.Current.IncomingMessageHeaders.FindHeader but i think this is looking at SOAP headers rather than HTTP headers.

So, how to read HTTP headers? Surely this is a simple question and i'm missing something obvious.

EDIT - @sinfere's answer was almost exactly what i needed. For completeness, here's what i ended up with:

IncomingWebRequestContext request = WebOperationContext.Current.IncomingRequest;
WebHeaderCollection headers = request.Headers;
string host = null;

if (headers["X-Forwarded-Host"] != null)
    host = headers["X-Forwarded-Host"];
else if (headers["Host"] != null)
    host = headers["Host"];
else 
    host = defaulthost; // set from a config value

解决方案

try WebOperationContext.Current.IncomingRequest.Headers

I use following codes to see all headers

IncomingWebRequestContext request = WebOperationContext.Current.IncomingRequest;
WebHeaderCollection headers = request.Headers;

Console.WriteLine("-------------------------------------------------------");
Console.WriteLine(request.Method + " " + request.UriTemplateMatch.RequestUri.AbsolutePath);
foreach (string headerName in headers.AllKeys)
{
  Console.WriteLine(headerName + ": " + headers[headerName]);
}
Console.WriteLine("-------------------------------------------------------");
