Window 应用程序与网站 WCF Web 服务通信

Question

我是新手，在实现与 Windows 应用程序和网站 WCF Web 服务的通信时遇到问题。它一直显示错误，我已经尝试了很多次。希望有人能帮帮我~~

网站

IApiService.cs

[ServiceContract]
public interface IApiService
{
    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    Boolean TestConnection();

    [OperationContract]  
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    Boolean IsPhoneNumberListMatch(int pa, int pb);

    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    List<ClientPhoneModel> GetAllPhoneNumber(string pa);

    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    List<ClientRegistrationModel> GetAllNewRegistration(string pa);
}

web.config

<system.serviceModel>
    <behaviors>
        <endpointBehaviors>
        <behavior name="EndBehavior">
            <webHttp />
        </behavior>
    </endpointBehaviors>
    <serviceBehaviors>
        <behavior name="ServiceBehavior">
            <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
            <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
    </serviceBehaviors>
    </behaviors>
    <services>
        <service behaviorConfiguration="ServiceBehavior" name="ApiService">
            <endpoint address="basic" binding="webHttpBinding" contract="IApiService" behaviorConfiguration="EndBehavior"/>
        </service>
        <service behaviorConfiguration="ServiceBehavior" name="WebService">
            <endpoint address="" binding="webHttpBinding" contract="IWebService" behaviorConfiguration="EndBehavior"/>
        </service>
    </services>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>

窗口应用程序

添加 localhost:5151/ApiService.svc 作为服务参考

Index.cs

try {
    Localhost.ApiServiceClient client = new Localhost.ApiServiceClient();
    client.TestConnection();
}
catch(Exception ex) {
    Log.Exception(ex);
}

App.config

<system.serviceModel>
    <behaviors>
        <serviceBehaviors>
                <behavior name="ServiceBehavior">
                    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
                    <serviceDebug includeExceptionDetailInFaults="true"/>
                </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
            <behavior name="EndBehavior">
                <webHttp/>
            </behavior>
        </endpointBehaviors>
    </behaviors>
    <client>
        <endpoint address="http://localhost:5151/ApiService.svc" behaviorConfiguration="EndBehavior" binding="webHttpBinding" contract="Localhost.IApiService" name="ApiServiceClient" />
    </client>
</system.serviceModel>

我能得到的最新错误是

Message : 
    Operation 'IsPhoneNumberListMatch' of contract 'IApiService' specifies multiple request body parameters to be serialized without any wrapper elements. At most one body parameter can be serialized without wrapper elements. Either remove the extra body parameters or set the BodyStyle property on the WebGetAttribute/WebInvokeAttribute to Wrapped.

请帮帮我~~~万谢

这可能不是您想要的答案，但我建议您在必须提供非肥皂绑定时不要在操作中使用多个参数。主要原因是只使用“Bare”bodyStyle，你可以获得一个很好的帮助页面。 尝试设置：

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

这将：

1. 让用户决定是使用 json 还是 xml 进行通信
   （自动FormatSelectionEnabled）
2. 设置默认 BodyStyle
3. 启用帮助页面

如果您这样做，您可以删除所有 WebInvoke 属性： [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]

您可以在以下位置找到帮助页面： http://your.domain/servicename/endpointAddress/help 因此，如果我在 service.motor.car 有一个名为 Engine.svc 的服务，并且我的端点地址是“v1/web”，我会在 http://service.motor.car/Engine.svc/v1/web/help 找到我的帮助页面

希望这会有所帮助:-)
