如何读取 WCF Web 服务中的 HTTP 请求标头? [英] How to read HTTP request headers in a WCF web service?

问题描述

在 WCF Web 服务中，如何读取 HTTP/HTTPS 请求标头?在这种情况下，我试图确定客户端使用的原始 URL 主机.这可能在来自负载均衡器的 X-Forwarded-Host 标头中，或者在主机标头中(如果它是直接框).

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.

我已经尝试过 OperationContext.Current.IncomingMessageHeaders.FindHeader 但我认为这是在查看 SOAP 标头而不是 HTTP 标头.

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

那么，如何读取 HTTP 标头?当然，这是一个简单的问题，我遗漏了一些明显的东西.

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

编辑 - @sinfere 的回答几乎正是我所需要的.为了完整起见，这是我最终得到的:

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

推荐答案

Try WebOperationContext.Current.IncomingRequest.Headers

我使用以下代码查看所有标题:

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("-------------------------------------------------------");
