Question

我创建了一个示例桌面应用程序来检查Windows应用程序中的自托管REST服务。这是我的样本

public class PayMentService : IPayMentService
{
    public string PayBill()
    {
        return "Transaction having PayId 12 was successful";
    }
}

[ServiceContract]
public interface IPayMentService
{
    [OperationContract]
    [WebInvoke(Method = "GET", UriTemplate = "/PayBill", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
    string PayBill();

}

我的配置文件就像

<configuration>
  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="JsonBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="SelfHostedWCFService.WCFService">
        <endpoint address="" behaviorConfiguration="JsonBehavior" binding="webHttpBinding"
          contract="SelfHostedWCFService.IWCFService" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8785" />
          </baseAddresses>
        </host>
      </service>
      <service name="SelfHostedWCFService.WCFCheck">
        <endpoint address="" binding="basicHttpBinding" contract="SelfHostedWCFService.IWCFCheck">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8733/Design_Time_Addresses/SelfHostedWCFService/WCFCheck/" />
          </baseAddresses>
        </host>
      </service>
      <service name="SelfHostedWCFService.PayMentService">
        <endpoint address="" binding="basicHttpBinding" contract="SelfHostedWCFService.IPayMentService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8733/Design_Time_Addresses/SelfHostedWCFService/PayMentService/" />
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>
</configuration>

我将其托管到配置的网址，如

    static void Main()
    {
        ServiceHost host = new ServiceHost(typeof(SelfHostedWCFService.PayMentService));
        host.Open();
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }

我尝试在网址http://localhost:8785/service/PayMentService/PayBill的帮助下致电我的服务。但它失败了。我知道服务正在运行，我可以在我的PayMentService构造函数中捕获我的请求，但我无法执行我的PayBill（）函数。我尝试了不同的选择，但没有任何作用。任何人都可以给出一些建议......？

提前致谢

我尝试在网址http://localhost:8785/service/PayMentService/PayBill的帮助下致电我的服务。但它失败了。您需要启用默认情况下关闭的元数据发现。您几乎就在那里，缺少的是

命名元服务行为实现。

 <serviceBehaviors>
        <behavior name="metadataDiscovery">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>

将其添加到您的付款服务。

 <service name="SelfHostedWCFService.PayMentService" behaviorConfiguration="metadataDiscovery">
        <endpoint address="" binding="basicHttpBinding" contract="SelfHostedWCFService.IPayMentService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

现在您可以浏览wsdl，http://localhost:8733/Design_Time_Addresses/SelfHostedWCFService/PayMentService/。同样，将行为标记配置添加到所有服务名称标记中。

您还解释了构造函数在调试模式下命中，代码中缺少一些东西。

 <endpointBehaviors>    
        <behavior name="JsonBehavior">   
          <webHttp/>    
        </behavior>    
      </endpointBehaviors>   

    <endpoint binding="webHttpBinding" 
contract="PayMentRESTService.IPayMentService" behaviorConfiguration="JsonBehavior">
