How to read HTTP request headers in a WCF web service?
提问by b w
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.
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 Host 标头中（如果它是直接框）。
I've tried OperationContext.Current.IncomingMessageHeaders.FindHeaderbut i think this is looking at SOAP headers rather than HTTP headers.
我试过了，OperationContext.Current.IncomingMessageHeaders.FindHeader但我认为这是在查看 SOAP 标头而不是 HTTP 标头。
So, how to read HTTP headers? Surely this is a simple question and i'm missing something obvious.
那么，如何读取 HTTP 标头呢？当然，这是一个简单的问题，我遗漏了一些明显的东西。
EDIT - @sinfere's answer was almost exactly what i needed. For completeness, here's what i ended up with:
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：
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

Try WebOperationContext.Current.IncomingRequest.Headers
尝试 WebOperationContext.Current.IncomingRequest.Headers
I use following codes to see all headers :
我使用以下代码查看所有标题：
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("-------------------------------------------------------");

This is how I read them in one of my Azure WCF web services.
这就是我在我的 Azure WCF Web 服务之一中读取它们的方式。
IncomingWebRequestContext woc = WebOperationContext.Current.IncomingRequest;
string applicationheader = woc.Headers["HeaderName"];
