我正在我的 WCF 服务中进行此调用:
public User GetStudentRecord(string userName)
{
try
{
return new DashboardFacade().GetStudentRecord(userName);
}
catch (Exception ex)
{
ServiceFault fault = new ServiceFault();
fault.Operation = "GetStudentRecord";
fault.Reason = "Who knows...";
fault.Message = ex.Message;
throw new FaultException<ServiceFault>(fault, fault.Message, new FaultCode(fault.Reason), fault.Operation);
}
}
DashboardFacade().GetStudentRecord(..) 定义如下:
public User GetStudentRecord(string userName)
{
User user = ctx.Users.Where(x => x.ADUserName == userName).SingleOrDefault();
return user;
}
ctx 是我的 DbContext。我首先使用实体框架代码。用户对象如下所示:
public class User
{
public User()
{
//UserDetails = new UserDetail();
}
[Key]
public Guid MasterKey { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string ADUserName { get; set; }
public string UserType { get; set; }
public virtual UserDetail UserDetails { get; set; }
public Nullable<DateTime> LastModifiedDate { get; set; }
}
最后,您可能需要查看 WCF 应用程序上的 web.config:
<?xml version="1.0"?>
<configuration>
<connectionStrings>
<add name="NotMyDBContextDB" connectionString="[omitted]" providerName="System.Data.SqlClient"/>
<add name="ApplicationContext" connectionString="Data Source=.;Initial Catalog=MyApp;Integrated Security=True;Pooling=False" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
谁能指出我在这里出错的地方?
这是我得到的确切错误:
An error occurred while receiving the HTTP response to http://localhost:5843/MyService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
Inner Exception:
The underlying connection was closed: An unexpected error occurred on a receive.
Inner Exception:
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
