使用ConfigurationChannelFactory.CreateChannel当请求头添加到

我需要使用ConfigurationChannelFactory.CreateChannel时请求头添加到WCF请求。

使用OperationContextScope我已经试过了。

我具有被如下所示的函数：

    public O Execute<O>(Func<T, O> action, string configFilePath, string endpoint, StringDictionary headers)
    {
        bool closed = false;
        T channel = default(T);
        O output = default(O);

        try
        {
            channel = this.GetChannel(configFilePath, endpoint);

            if (headers != null && headers.Count > 0)
            {
                (channel as IClientChannel).Open();
                using (new OperationContextScope(channel as IClientChannel))
                {
                    HttpRequestMessageProperty requestMessage = new HttpRequestMessageProperty();
                    foreach (DictionaryEntry header in headers)
                    {
                        requestMessage.Headers[header.Key.ToString()] = header.Value.ToString();
                    }

                    OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = requestMessage;
                    output = action(channel);
                }
                (channel as IClientChannel).Close();
            }
            else
            {
                (channel as IClientChannel).Open();
                output = action(channel);
                (channel as IClientChannel).Close();
            }

            closed = true;
        }
        finally
        {
            if (!closed && channel != null)
            {
                (channel as IClientChannel).Abort();
            }
        }

        return output;
    }

    private T GetChannel(string configFilePath, string endpoint)
    {
        //Get the ChannelFactoryObject
        ConfigurationChannelFactory<T> wcfClientFactory = null;
        ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap { ExeConfigFilename = configFilePath };
        wcfClientFactory = new ConfigurationChannelFactory<T>(endpoint, ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None), null); 
        return wcfClientFactory.CreateChannel();
    }

配置文件条目：

&lt;security mode="Transport"&gt;
   &lt;transport clientCredentialType="None" proxyCredentialType="None" realm="" /&gt;;clientCredentialType="Windows" negotiateServiceCredential="true" /&gt;
&lt;/security&gt;

上述功能是从另一个cs文件调用，如以下所示，通过Func<T,O>作为参数：

Execute&lt;MyService.InformationResponse[]&gt;=&gt;IMyService.GetInformation(Request), ConfigPath, myServiceEndPoint, headers);

我得到400错误请求的服务的请求头，它是不是能找到期待“授权”。

我们可以使用WebOperationContext类来修改，并添加HTTP头，请参考下面的代码段。

  IService service = factory.CreateChannel();
            using (OperationContextScope scope = new OperationContextScope((IContextChannel)service))
            {
                WebOperationContext.Current.OutgoingRequest.ContentType = "application/json; charset=utf-8";
                WebOperationContext.Current.OutgoingRequest.Headers.Add("Authorization", "bearer xxxxxxxx");
                service.GetData();
            }

结果。
