WCF AfterReceiveRequest 获取标头 [英] WCF AfterReceiveRequest get headers

问题描述

我刚刚开始拦截对我的 WCF 服务的请求.

I just got started intercepting requests to my WCF service.

我正在使用如下所示的 Java 代码调用 Web 服务(简短版本)

I'm calling the web service with java code that looks like this ( short version )

connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("Username", "Testname");

我收到了请求，但我无法获取/找到消息请求中的标头.我试过这样的事情:

I'm receiving the request but I cant get/find the headers in the message request. I've tried something like this:

public object AfterReceiveRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel, System.ServiceModel.InstanceContext instanceContext)
{
    int headerIndex = request.Headers.FindHeader("Username", string.Empty);
    var username = request.Headers["Username"]

    return null;
}

但我总是以 -1 或异常结束.这样做的正确方法是什么?我在 Java 方面也做错了吗?

But I always end up with -1 or exceptions. What is the right way to do this? Am I doing it wrong on the Java side as well?

推荐答案

Message 类中的 Headers 属性将为您提供 SOAP标题；您正在寻找的是 HTTP 标头.要获得这些，您应该使用 HttpRequestMessageProperty:

The Headers property in the Message class will give you the SOAP headers; what you're looking for are the HTTP headers. To get to those, you should use the HttpRequestMessageProperty:

    public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
    {
        var prop = (HttpRequestMessageProperty)request.Properties[HttpRequestMessageProperty.Name];
        var userName = prop.Headers["Username"];

        return null;
    }
