C#调用WebService时插入cookie

 

SOAPUI插入Cookie的方法

 

SOAP插入cookie的方法如下,点击Head,点击加号,然后直接设置就可以了。

 

C#中调用webService时插入Cookie

 

由于调用的时候必须要带上cookie,才能成功获取到数据,而正常的通过引用服务,C#会生成一堆代码,但那只是个空壳子,并没有设置cookie的地方。在网上找了很多资料,最后找到了方法,在此总结一下,以便其他人少走弯路。

 

由于我们是客户端,服务端无法控制,所以网上找到那些设置config,什么启用cookie啊,都是没用的,除非你是正在开发的是服务端+客户端。这里我们主要讨论的是调用方,我只有一个wsdl的地址,服务端不可控制的情况。

 

客户端(web应用)并不会自动发送cookie到wcf。所以客户端还得做更多的工作

 

 

  1. 核心在IClientMessageInspector 这个接口,他有BeforeSendRequest和AfterReceiveReply两个方法。
  2. 我们要新建一个类CookieBehavior.cs

     

    public class CookieBehavior : IEndpointBehavior
    {
        private string SID { get; set; }

        public CookieBehavior(string pSid)
        {
            SID = pSid;
        }

        public void Validate(ServiceEndpoint endpoint)
        {
            return;
        }

        public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
        {
            return;
        }

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

        public void ApplyClientBehavior(ServiceEndpoint serviceEndpoint, ClientRuntime behavior)
        {
            behavior.MessageInspectors.Add(new CookieMessageInspector(SID));
        }
    }

  

 

  1. 建立一个类CookieMessageInspector,继承IClientMessageInspector,实现他的BeforeSendRequest和AfterReceiveReply两个方法。

     

      public class CookieMessageInspector : IClientMessageInspector
        {
            private string SID { get; set; }
    
            public CookieMessageInspector(string pSid)
            {
                SID = pSid;
            }
    
            public object BeforeSendRequest(ref Message request, System.ServiceModel.IClientChannel channel)
            {
                var cookie = "SID=" + SID;
    
                HttpRequestMessageProperty httpRequestMessage;
                object httpRequestMessageObject;
    
                if (request.Properties.TryGetValue(HttpRequestMessageProperty.Name, out httpRequestMessageObject))
                {
                    httpRequestMessage = httpRequestMessageObject as HttpRequestMessageProperty;
                    if (string.IsNullOrEmpty(httpRequestMessage.Headers["Cookie"]))
                    {
                        httpRequestMessage.Headers["Cookie"] = cookie;
                    }
                }
                else
                {
                    httpRequestMessage = new HttpRequestMessageProperty();
                    httpRequestMessage.Headers.Add("Cookie", cookie);
                    request.Properties.Add(HttpRequestMessageProperty.Name, httpRequestMessage);
                }
    
                return null;
            }
    
            public void AfterReceiveReply(ref Message reply, object correlationState)
            {
                return;
                
            }
        }
    

      

     

     

  2. 通过vs添加服务引用,他会自动生成一个代理类。在new这个代理类之后,加入我们新建的behavior

 

            WokSearchLiteClient searchLiteClient = new WokSearchLiteClient();
            CookieBehavior c = new CookieBehavior(authentKey);
            searchLiteClient.Endpoint.Behaviors.Add(c);
            var ret = searchLiteClient.search(searchRequest.queryParameters, searchRequest.retrieveParameters);

  

 

这样就完成了,带cookie的webService调用
