将HTTP标头添加到服务参考服务方法 [英] Adding http headers to a Service Reference service method

问题描述

我已经从WSDL生成了服务引用.我已经成功地根据服务引用对客户端进行了编码.我一直在使用serviceRef.serviceMethod(params ...)的模式来调用基于服务的方法.现在，我需要在发送的邮件中添加http标头.我找不到在哪里为服务的所有消息将它们设置为默认值，也找不到在调用某些方法时可以在何处设置它们的位置.一些文章建议我可以使用IClientMessageInspector，但是实现似乎很复杂.有什么建议吗?

I have generated a service reference from a WSDL. I have been coding a client against the service reference successfully. I have been using a pattern of serviceRef.serviceMethod(params...) to invoke the service based methods. Now I need to add http headers to my sent messages. I can't find where to set them as default for all messages for the service nor can I find where I can set them when invoking certain methods. Some articles suggest I could use IClientMessageInspector but the implementation seems complicated. Any suggestions?

推荐答案

从很多地方借来的钱，但大部分是:

Borrowing from many places but mostly:

我简化了，但是我想我有一个实现将添加自定义httpheader.

I simplified but I think I have an implementation that will add custom httpheaders.

    public class HttpHeaderMessageInspector : IClientMessageInspector
    {
        private readonly Dictionary<string, string> _httpHeaders;

        public HttpHeaderMessageInspector(Dictionary<string, string> httpHeaders)
        {
            this._httpHeaders = httpHeaders;
        }

        public void AfterReceiveReply(ref Message reply, object correlationState) { }

        public object BeforeSendRequest(ref Message request, IClientChannel channel)
        {
            HttpRequestMessageProperty httpRequestMessage;
            object httpRequestMessageObject;

            if (request.Properties.TryGetValue(HttpRequestMessageProperty.Name, out httpRequestMessageObject))
            {
                httpRequestMessage = httpRequestMessageObject as HttpRequestMessageProperty;

                foreach (var httpHeader in _httpHeaders)
                {
                    httpRequestMessage.Headers[httpHeader.Key] = httpHeader.Value;
                }
            }
            else
            {
                httpRequestMessage = new HttpRequestMessageProperty();

                foreach (var httpHeader in _httpHeaders)
                {
                    httpRequestMessage.Headers.Add(httpHeader.Key, httpHeader.Value);
                }
                request.Properties.Add(HttpRequestMessageProperty.Name, httpRequestMessage);
            }
            return null;
        }
    }

internal class HttpHeadersEndpointBehavior : IEndpointBehavior
    {
        private readonly Dictionary<string,string> _httpHeaders;

        public HttpHeadersEndpointBehavior(Dictionary<string, string> httpHeaders)
        {
            this._httpHeaders = httpHeaders;
        }
        public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters) { }

        public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
        {
            var inspector = new HttpHeaderMessageInspector(this._httpHeaders);

            clientRuntime.MessageInspectors.Add(inspector);
        }

        public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { }
        public void Validate(ServiceEndpoint endpoint) { }
    }

然后在更新我的服务参考之后:

Then after newing up my service reference:

    var httpHeaders = new Dictionary<string, string>();
    httpHeaders.Add("header1", "value1");
    httpHeaders.Add("header2", "value2");

    _serviceRef.Endpoint.Behaviors.Add(new HttpHeadersEndpointBehavior(httpHeaders));

没有其他改变.如果您想到了更简单的方法，请告诉我.

Nothing else had to change. If you think of a simpler way, let me know.
