这是我的第一个网络服务,我正在尝试按照有关为Web服务创建自定义身份验证的教程,因为我收到此错误而停滞不前:
值'WcfOrderingService.Services.AuthenticationTokenService'根据其数据类型'serviceNameType'无效 - 枚举约束失败。
网络配置:
<service name ="WcfOrderingService.Services.AuthenticationTokenService"
behaviorConfiguration="ServiceBehaviourHttp">
<endpoint address="" behaviorConfiguration="WcfOrderingService.AuthenticationTokenServiceAspNetAjaxBehavior"
binding="webHttpBinding" contract="WcfOrderingService.Services.AuthenticationTokenService.Authenticate" />
</service>
.svc.cs -
namespace WcfOrderingService.Services
{
[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class AuthenticationTokenService
{
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
[OperationContract]
public string Authenticate(Credentials creds)
{
ICredentialsValidator validator = new CredentialsValidator();
if (validator.IsValid(creds))
return new TokenBuilder().Build(creds);
throw new InvalidCredentialException("Invalid credentials");
}
}
}
我已经尝试过我在网上找到的大部分内容,服务名称的变体等,但无法找到答案。
提前致谢。

可能对该服务的引用不再正常工作。这可能有几个原因。
解决方案是首先删除服务引用,然后再次添加。

以下是导致我的Web.config错误的原因
<service name="case_info">
<endpoint address="" behaviorConfiguration="case_infoAspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration="webBinding" contract="ICase_Info" />
</service>
我似乎已通过将服务和合同(接口)移到命名空间中解决了该问题。
<service name="mynamesp.case_info">
<endpoint address="" behaviorConfiguration="case_infoAspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration="webBinding" contract="mynamesp.ICase_Info" />
</service>
事实证明,只要您在运行项目时将Web.config保持打开状态,那么所有这些都将正常运行。我最终将服务从名称空间中移出,根本没有实现接口。
<ServiceContract(Namespace:="http://edwardo.com/services/")>
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>
Public Class case_info
<WebGet(ResponseFormat:=WebMessageFormat.Json)>
<OperationContract()>
Public Function GetCasePopup(CaseID As Int32) As CasePopupInfo
Return CasePopup.GetCasePopup(CaseID)
End Function
End Class
Web.config中的以下两项对使此功能通过https工作至关重要。
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="webBinding">
<security mode="Transport" />
</binding>
</webHttpBinding>
</bindings>
</system.serviceModel>
<system.webServer>
<handlers>
<add name=".svc" verb="*" path="*.svc" type="System.ServiceModel.Activation.ServiceHttpHandlerFactory, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</handlers>
</system.webServer>
因此,也许可以摆脱一些话题,但这也许会对某人有所帮助。
