通过 GET 请求和响应将对象传递给 WCF 服务

Question

我对 WCF 服务有点陌生。在我目前，我开发了一个 hello world Restful WCF 服务。以下是我的 RESTful Web 服务的代码。

RESTful 服务契约如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace RestfulWCFService
{
    [ServiceContract]
    public interface IRestfulTestService
    {
        [OperationContract]
        [WebInvoke(Method="GET", ResponseFormat= WebMessageFormat.Xml, UriTemplate="xml/{name}")]
        string SayHelloXml(string name);

        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "json/{name}")]
        string SayHelloJson(string name);
    }
} 

接口实现如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace RestfulWCFService
{

    public class RestfulTestService : IRestfulTestService
    {


        string IRestfulTestService.SayHelloXml(string name)
        {
            return "Hello  " + name;
        }

        string IRestfulTestService.SayHelloJson(string name)
        {
            return "Hello  " + name;
        }
    }
}

我已在 IIS 上部署此服务，现在我正在使用以下 URL 访问此 Web 服务。

http://localhost/RestfulWCFService/RestfulTestService.svc/xml/pankesh

网络服务正在向我返回以下数据。

<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">Hello pankesh</string> 

现在，我的问题是 - 在上面的 web 服务中，我传递了一个简单的数据类型，即 STRING。现在，我的要求是我想通过 REST 请求传递一个复杂的自定义对象。您能否告诉我 - 在上述情况下，如何通过 REST 请求传递自定义对象？

web.config文件内容如下：

<?xml version="1.0" encoding="utf-8"?>
<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="RestfulWCFService.RestfulTestService">
        <endpoint behaviorConfiguration="WebBehavior" binding="webHttpBinding" bindingConfiguration="" contract="RestfulWCFService.IRestfulTestService" />
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="WebBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
    <!--
        To browse web app root directory during debugging, set the value below to true.
        Set to false before deployment to avoid disclosing web app folder information.
      -->
    <directoryBrowse enabled="true" />
  </system.webServer>

</configuration>

Answer 1

1. 将对象序列化为流
2. 作为流传递给服务
3. 反序列化为数据契约
   Serializing/deserializing with memory stream
