在现有 WCF SOAP 服务中添加 Http 标头不起作用 [英] Adding Http Header in an existing WCF SOAP Service is not working

问题描述

我想要一个 HTTP 标头到我的 WCF SOAP 服务.我的最终目标是通过这个 HTTP 标头发送 API 密钥.

I would like to an HTTP header to my WCF SOAP Service. My end goal is to send API keys through this HTTP header.

下面是我的代码:

[ServiceBehavior(Namespace = "http://****.com/**/1.1")]
public class MyWcfSvc : IMyVerify
{
    const int MaxResponseSize = 0xffff; // 64K max size - Normally it will be MUCH smaller than this

    private static readonly NLogLogger Logger;

    static MyWcfSvc()
    {
        Logger = new NLogLogger();
        // Add an HTTP Header to an outgoing request 
        HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();
        requestMessage.Headers["User-Auth"] = "MyHttpHeaderValue";
        OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;
    }
}

我在 HTTP 请求标头下没有看到 User-Auth 标头.

I do not see User-Auth header under HTTP request headers.

我也尝试过另一种方式.

I also tried with another way.

public AnalyzeResponse Analyze(AnalyzeRequest analyzeRequest)
    {
        HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();
        requestMessage.Headers["User-Auth"] = "MyHttpHeaderValue";
        OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;
.
.
. Rest of the service implementation
.
.
.
}

但是，我仍然没有在请求消息中看到任何 HTTP 标头信息.我正在使用 SOAP UI 发送请求并查看响应.

But, still, I don't see any HTTP header information with the request message. I am using SOAP UI to send the requests and to view the responses.

我该怎么办?我是否应该对与课程相关的服务进行更改?或者我需要对 web.config 文件进行一些更改?

How should I go about this? Am I suppose to make changes to the Service related to class? Or I need to make some changes to web.config file?

推荐答案

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]); 
}
