是否可以通过城堡温莎注入 WCF REST 服务客户端答案

【问题标题】：Is it possible to inject WCF REST service client via castle windsor是否可以通过城堡温莎注入 WCF REST 服务客户端

【问题描述】：

我创建了两个 WCF 休息服务 service1 和 service2 托管在不同的端口中，并在 service1 中使用 Castle Windsor 进行依赖注入，现在从 service1 尝试调用 service2。但是当我创建一个实例并调用service2 时，我收到一个异常说bad request(400)。当我从 REST 客户端请求 service2 时，我能够获得 200 response。错误是由于温莎城堡的生活方式行为造成的吗？。

容器配置（服务 1）

Container.AddFacility<WcfFacility>().Register(
                           Component.For(type).AsWcfClient(
                               new DefaultClientModel { 
                                       Endpoint = WcfEndpoint.FromConfiguration("*") }));

配置（服务 1）

<system.serviceModel>
<client>
    <endpoint address="http://localhost:8082/BLDBService" binding="webHttpBinding" bindingConfiguration="customHttpBinding" contract ="DataSourceContracts.IBLDBService" behaviorConfiguration ="serviceEndpointHttpBehavior">
  </endpoint>
</client>
<services>
  <service name="BusinessService.MetaDataService" behaviorConfiguration="basicHttpBehavior">        
    <host>
      <baseAddresses >
        <add baseAddress ="http://localhost:8084/"/>
      </baseAddresses>
    </host>
   <endpoint address="MetaDataService" binding="webHttpBinding" contract ="BusinessServiceContracts.IMetaDataService" behaviorConfiguration="endpointHttpBehavior" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
<bindings>
  <!--<basicHttpsBinding>
    <binding name="BasicHttpsBinding">
      <security mode="Transport">
        <transport clientCredentialType="None"></transport>
      </security>
    </binding>
  </basicHttpsBinding>-->
  <webHttpBinding>
    <binding name ="customHttpBinding" transferMode ="Streamed">          
    </binding>
  </webHttpBinding>
</bindings>
<behaviors>
  <endpointBehaviors>
    <behavior name="endpointHttpBehavior">
      <webHttp helpEnabled ="true" automaticFormatSelectionEnabled ="true" defaultOutgoingResponseFormat ="Json"></webHttp>
    </behavior>
    <behavior name="serviceEndpointHttpBehavior">
      <webHttp defaultOutgoingResponseFormat="Json" automaticFormatSelectionEnabled ="true" helpEnabled ="true"  />
      <dataContractSerializer/>
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="basicHttpBehavior">
     <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

服务调用（服务 1）

_bldbService = Container.resolve<IBLDBService>();
WebOperationContext.Current.OutgoingRequest.ContentType = "application/json";
viewModel = _bldbService.GetBLDBData(viewModel);

配置（服务2）

 <service name="BusinessService.BLDBService" behaviorConfiguration="basicHttpBehavior">
    <!--<endpoint address="net.tcp://localhost:8082/BLDBService" binding="netTcpBinding" contract="BusinessServiceContracts.IBLDBService"/>-->
    <host>
      <baseAddresses>
        <add baseAddress ="http://localhost:8082/"/>
      </baseAddresses>
    </host>
    <endpoint address="BLDBService" binding="webHttpBinding"    contract ="BusinessServiceContracts.IBLDBService" behaviorConfiguration="endpointHttpBehavior"/>
  </service>

从 REST 客户端调用时

附：我用 net/tcp 协议测试过，效果很好。

【问题讨论】：

您分享的代码是从“Service1”调用“Service2”？您是否也为“Service2”配置了设置和容器？你也可以分享那个配置吗？您是否尝试调试并检查它是否到达了“Service2”代码？
@chetan-ranpariya 如果我从 REST 客户端调用，它将到达并给出 200 响应，但是当我通过 Castle Windsor 容器实例调用时，它说请求错误，这意味着请求将发送到服务器但请求类型无效.
当您收到服务的“Bad Request”响应时，是否还有其他信息，例如错误信息、数据验证错误、授权失败等？此外，当您调试“Service1”时，它是否在“Service1”中达到viewModel = _bldbService.GetBLDBData(viewModel); 行？
更新了日志详细信息
奇怪的行为。第一眼看不出有什么问题。可能您可能想检查客户端应用程序和服务端的绑定设置是否同步，并且您可以在服务端启用跟踪以查看发送意外响应的原因是什么。 msdn.microsoft.com/en-us/library/ms733025.aspx

【解决方案1】：

终于找到答案了。

我将服务的请求-响应格式硬编码为 JSON。现在我从服务合同中删除了它，它工作得很好。新的服务合同和 web.config 如下所示。

namespace DataSourceContracts
{
using System.ServiceModel;
using System.ServiceModel.Web;
using ViewModel.DataSource;

    /// <summary>
    /// This is same as the exposed BLDB data REST service in abother project we need to keep both in sync. 
    /// The reason for not refering to the same project is the .Net framework version
    /// </summary>
    [ServiceContract]
    public interface IBLDBService : IDataSourceService
    {
        /// <summary>
        /// Sample method
        /// </summary>
        /// <param name="viewModel"></param>
        /// <returns></returns>
        [OperationContract]
        [WebInvoke(Method = "POST",  UriTemplate = "GetBLDBData")]
        MetaDataViewModel GetBLDBData(MetaDataViewModel viewModel);
    }
}

Web.Config

  <behaviors>
      <endpointBehaviors>
        <behavior name="endpointHttpBehavior">
          <webHttp helpEnabled="true" automaticFormatSelectionEnabled="true"  defaultBodyStyle="Bare"></webHttp>
        </behavior>
    </endpointBehaviors>
</behaviors>
