服务元数据可能无法访问在WCF

我打电话给我使用Ajax的wcf服务，为此我配置了我的web.config文件。但现在当我运行我的服务时，它会发出这样的错误。服务元数据可能无法访问在WCF

Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata.

这是我Interface

namespace WcfWithJson 
{ 
    [ServiceContract] 
    public interface IMyservice 
    { 
     [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)] 
     UserDetails[] GetUserDetails(string Username); 
    } 
}

注：为userDetails是我的类名。现在我已经实现了我的界面这里

namespace WcfWithJson 
{ 
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
    public class MyService : IMyservice 
    { 
     public UserDetails[] GetUserDetails(string Username) 
     { 
      string strConnection = ConfigurationManager.ConnectionStrings["MyDbEntities"].ConnectionString; 
      List<UserDetails> userdetails = new List<UserDetails>(); 
      using (SqlConnection con = new SqlConnection(strConnection)) 
      { 
       // some sql Code here 
      } 
      return userdetails.ToArray(); 
     } 
    } 
}

，这是我web.config文件

<system.serviceModel> 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> 
    <services> 
     <service name="WcfWithJson.MyService" behaviorConfiguration="metadataBehavior"> 
     <endpoint address="" binding="basicHttpBinding" contract="WcfWithJson.IMyservice" behaviorConfiguration="EndPointBehavior" /> 
     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> 
     </service> 
    </services> 
    <behaviors> 
     <serviceBehaviors> 
     <behavior name="ServiceBehavior"> 
      <serviceMetadata httpGetEnabled="true"/> 
      <serviceDebug includeExceptionDetailInFaults="true"/> 
     </behavior> 
     </serviceBehaviors> 
     <endpointBehaviors> 
     <behavior name="EndPointBehavior"> 
      <enableWebScript /> 
     </behavior> 
     </endpointBehaviors> 
    </behaviors> 
    </system.serviceModel> 
    <system.webServer> 
    <modules runAllManagedModulesForAllRequests="true"/> 
    </system.webServer>

这是完全错误：

Error: Cannot obtain Metadata from http://localhost:61762/MyService.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.

尝试为元数据添加额外的端点。 – jadavparesh06 2014-10-09 05:19:47

@ jadavparesh06：我加了这个，但是仍然有同样的问题 – 2014-10-09 05:33:19

在WCF的情况下使用Ajax，该<endpoint />为服务应该使用WebHttpBinding和ASP.NET AJAX行为conf在<endpointBehaviors>标记下配置。

所以，条目应该是：

<services> 
<service name="WcfWithJson.MyService" behaviorConfiguration="ServiceBehavior"> 
    <endpoint address="" binding="webHttpBinding" 
    contract="WcfWithJson.IMyservice" behaviorConfiguration="EndPointBehavior" /> 
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> 
</service> 
</services>

[所述<service>标记的“behaviourConfiguration”属性应该被设置为构造成用于该服务的相应的行为。在这里，您已经配置了名称为“ServiceBehaviour”的服务的行为 ]
