Question

经过几天的测试后，我发现使用身份验证创建WCF Web服务的唯一方法是将证书放在localmachine / trustedpeople证书库中。主持人不会为我这样做。您知道如何在不在该商店中放置证书的情况下启用WCF身份验证吗？有没有其他方法可以让WCF安全工作在共享主机上？

我已经在codeproject上使用了一个示例，该示例将证书放在app_data中，但我无法让它工作。

我在本地IIS上做了一些非常简单的测试。我用单一方法提供非常简单的服务。要公开服务，我使用此配置：

<configuration>
  <appSettings>
    <add key="CertificatePath" value="D:\Applications\CertificateFromFile\App_Data\ServerCert.pfx" />
    <add key="CertificatePassword" value="password" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="CertificateFromFile.MyPasswordValidator, CertificateFromFile" />
          </serviceCredentials>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <protocolMapping>
      <clear />
      <add scheme="http" binding="wsHttpBinding" />
    </protocolMapping>
    <bindings>
      <wsHttpBinding>
        <binding>
          <security mode="Message">
            <message clientCredentialType="UserName" establishSecurityContext="false" negotiateServiceCredential="false" />
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true">
      <serviceActivations>
        <add service="CertificateFromFile.MyService" factory="CertificateFromFile.MyServiceHostFactory" relativeAddress="Service.svc" />
      </serviceActivations>
    </serviceHostingEnvironment>
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
  </system.webServer>
</configuration>

配置定义：

两个自定义appSettings，描述证书和密码的路径。
基于配置的激活的单一服务 - 它将具有带有wsHttpBinding（通过protocolMapping定义）的默认端点，需要进行消息级别身份验证。
定义自定义密码验证程序但没有服务证书的默认行为！
使用自定义ServiceHostFactory在自定义服务主机上激活服务。

加载证书的神奇之处在于自定义服务主机和服务主机工厂：

namespace CertificateFromFile
{
    public class MyServiceHostFactory : ServiceHostFactory
    {
        protected override System.ServiceModel.ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
            string path = ConfigurationManager.AppSettings["CertificatePath"];
            string password = ConfigurationManager.AppSettings["CertificatePassword"];
            return new MyServiceHost(serviceType, path, password, baseAddresses);
        }
    }

    public class MyServiceHost : ServiceHost
    {
        private readonly string _certificatePath;
        private readonly string _certificatePassword;

        public MyServiceHost(Type serviceType, string certificatePath, string certificatePassword, params Uri[] baseAddresses)
            : base(serviceType, baseAddresses)
        {
            _certificatePath = certificatePath;
            _certificatePassword = certificatePassword;
        }

        protected override void OnOpening()
        {
            base.OnOpening();

            var certificate = new X509Certificate2(_certificatePath, _certificatePassword);
            var credentials = Description.Behaviors.Find<ServiceCredentials>();
            credentials.ServiceCertificate.Certificate = certificate;
        }
    }
}
