Wcf REST 服务和客户端

Question

你好，我找了很久，但每一个答案都没有解决我的问题。我有 REST 服务

namespace WcfService1
{

[ServiceContract]
public interface IRestServiceImpl
{
    [OperationContract]
    [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Xml,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "images")]
    List<MyImage> getImages();        
}
[DataContract]
public class MyImage
{
    public MyImage(string name, Image img)
    {
        Name = name;
        Img = img;
    }
    [DataMember]
    public string Name
    {
        get;
        set;
    }
    [DataMember]
    public Image Img
    {
        get;
        set;
    }
}
}

实现如下：

namespace WcfService1
{

public class RestServiceImpl : IRestServiceImpl
{
    public List<MyImage> getImages()
    {
        List<MyImage> images = new List<MyImage>();
        string[] files = Directory.GetFiles(AppDomain.CurrentDomain.BaseDirectory, "*.jpg");

        foreach (string file in files)
        {
            Image im = Image.FromFile(file);
            images.Add(new MyImage(file, im));
        }
        return images;
    }
}
}

Web.Config:

    <?xml version="1.0"?>
     <configuration>
      <system.web>
       <compilation debug="true" targetFramework="4.0" />
      </system.web>
      <system.serviceModel>
       <services>
        <service name="WcfService1.RestServiceImpl" behaviorConfiguration="ServiceBehaviour">
         <endpoint address="" binding="webHttpBinding" contract="WcfService1.IRestServiceImpl" behaviorConfiguration="web">        
         </endpoint>
        </service>
       </services>
       <behaviors>
        <serviceBehaviors>
         <behavior name="ServiceBehaviour">
           <serviceMetadata httpGetEnabled="true"/>
           <serviceDebug includeExceptionDetailInFaults="false"/>
         </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
        <behavior name="web">
         <webHttp/>
        </behavior>
       </endpointBehaviors>
      </behaviors>
      <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
     </system.serviceModel>
     <system.webServer>
      <modules runAllManagedModulesForAllRequests="true"/>
     </system.webServer>
    </configuration>

接下来，我创建了客户端应用程序并添加了服务引用，并从上层声明的本地主机中选择引用

有客户端代码

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        ServiceReference1.RestServiceImplClient service = new ServiceReference1.RestServiceImplClient();

        ServiceReference1.MyImage[] images = service.getImages();
        service.Close();
        List<ServiceReference1.MyImage> files = images.Select(im => new ServiceReference1.MyImage() { Img = im.Img, Name = im.Name }).ToList();

        listViewImages.ItemsSource = files;

    }
}

这一行：

ServiceReference1.MyImage[] images = service.getImages();

我有例外：

There was no endpoint listening at http://localhost:55008/RestServiceImpl.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

当我查看 InnerException 时，我有：

The remote server returned an error: (404) Not Found.

这是我的 app.config 客户文件：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
 <system.serviceModel>
  <client>
   <endpoint address="http://localhost:55008/RestServiceImpl.svc" binding="basicHttpBinding" contract="ServiceReference1.IRestServiceImpl">
   </endpoint>
  </client>
  <behaviors>
   <serviceBehaviors>
    <behavior name="ServiceBehaviour">
     <serviceMetadata httpGetEnabled="true"/>
     <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
   </serviceBehaviors>
  </behaviors>
 </system.serviceModel>
</configuration>

我知道这个话题很受欢迎，但所有的答案都帮不了我。

Answer 1

根据您发布的代码，服务 web.config 没有带 BasicHttpBinding 的端点。要通过代理使用服务，我相信您需要根据问题中的客户端 web.config 添加带有 BasicHttpBinding 的端点。它确实公开了一个 REST 端点。要调用 REST 服务，您可以使用 url 调用，如下所示。

http://localhost:55008/RestServiceImpl.svc/images

Answer 2

尝试在客户端代码中添加 REST 服务的 Web 引用而不是服务引用。
