Question

这可能是WCF中非常基本的问题。我是新手，不知道如何解决这个问题。

我已经从visual studio中获取了WCF服务应用程序模板，这里是我所拥有的代码

**接口：IService1.cs **

using System.ServiceModel;
namespace WcfService1
{
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);
    }
}

**服务文件名：Service1.svc **

using System.ServiceModel;
namespace WcfService1
{
    public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }
    }
}

我已将web.config文件编辑为

<?xml version="1.0"?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="mexBehaviour">
          <serviceMetadata httpGetEnabled="True"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="mexBehaviour" name="WcfService1.IService1">
        <endpoint address="Service1" binding="basicHttpBinding" contract="WcfService1.IService1"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>
  <system.web>
    <compilation debug="true"/>
  </system.web>
</configuration>

，我得到的错误是： 无法添加服务。可能无法访问服务元数据。确保您的服务正在运行并公开元数据。

Visual Studio生成的原始Webconfig文件

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>  
</configuration>

我确信这必须是简单的配置文件问题。不知道如何弄明白。感谢您的帮助。

修改Web.config以添加netTcpBinding Binding，这会在WCF testClient中抛出错误：

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="mexBehaviour">
          <serviceMetadata httpGetEnabled="True"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="mexBehaviour" name="WcfService1.Service1">
        <endpoint address="Service1" binding="basicHttpBinding" contract="WcfService1.IService1"/>
        <endpoint address="Service1" binding="netTcpBinding" contract="WcfService1.IService1"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/"/>
            <add baseAddress="net.tcp://localhost:8090/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>

项目2：在控制台应用中托管的BasicHttp和NetTcp绑定

我有以下web.config文件（刚刚再次复制，以便我们可以一目了然）

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="HelloService.HelloService"  behaviorConfiguration="mexBehaviour">
        <endpoint address="HelloService" binding="basicHttpBinding" contract="HelloService.IHelloService"></endpoint>
        <endpoint address="HelloService" binding="netTcpBinding" contract="HelloService.IHelloService"></endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:59084/"/>
            <add baseAddress="net.tcp://localhost:59076/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="mexBehaviour">
          <serviceMetadata httpGetEnabled="True"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

和用于托管的控制台应用代码

using System.ServiceModel;

namespace HelloServiceHost
{
    class Program
    {
        static void Main()
        {
            using(ServiceHost host  = new ServiceHost(typeof(HelloService.HelloService)))
            {
                host.Open();
                Console.WriteLine("Host Started");
                Console.ReadLine();
            }
        }
    }
}

错误：我在host.Open（）方法中遇到错误，

 HTTP could not register URL http://+:8080/. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details).

我尝试了其他端口号，如53895，认为端口8080可能是预先的占据。没运气！！
当我浏览这个错误时，我来了由于我的帐户不是管理员，因此知道此问题。现在我怀疑了 WCFTest客户端也在我的帐户下执行。怎么运行类似的代码，我可以＆＃39;
此外，任何建议，以此工作会得到满足。可能与Webconfig有关再次??

扩展接口

的类

using System.ServiceModel;
namespace HelloService
{
    public class HelloService : IHelloService
    {
        public string GetMessage(string Name)
        {
            return "Hello " + Name;
        }
    }
}

界面：

namespace HelloService
{
    [ServiceContract]
    public interface IHelloService
    {
        [OperationContract]
        String GetMessage(String Name);
    }
}

提前致谢!!

Answer 1

web.config中的所有内容看起来都没问题，但有一个例外：下面一行中的“名称”应为“WcfService1.Service1”而不是“WcfService1.IService1”：

<service behaviorConfiguration="mexBehaviour" name="WcfService1.Service1">

我的网页配置如下，对我有用：

<?xml version="1.0"?>
<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>
    <behaviors>
      <serviceBehaviors>
        <behavior name="mexBehaviour">
          <serviceMetadata httpGetEnabled="True"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="mexBehaviour" name="WcfService1.Service1">
        <endpoint address="Service1" binding="basicHttpBinding" contract="WcfService1.IService1"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <directoryBrowse enabled="true"/>
  </system.webServer>
</configuration>

Answer 2

有时，system.web部分下面的以下web.config行可能会导致您的开发计算机出现问题

<identity impersonate="true" />
