如何在WCF服务中使用角色管理器?

在我的.NET应用程序中,我可以使用[Authorize(Roles=)]标记限制类或方法。如何为我的WCF服务启用此功能?

我目前为每个端点设置了以下绑定:

  <webHttpBinding>
    <binding name="TransportSecurity" maxReceivedMessageSize="5242880">
      <security mode="Transport">
        <transport clientCredentialType="None"/>
      </security>
    </binding>
  </webHttpBinding>

由于我希望用户登录并接收带主体的cookie,我是否需要将其更改为另一种clientCredentialType

修改1:

这是使用REST,而不是SOAP。还需要注意的是,它适用于移动设备(Android,iPhone)并且可以使用cookie来维护会话。到目前为止,我无法使用以下代码/配置来实现此功能:

配置文件:

   <roleManager enabled="true" defaultProvider="ActiveDirectoryRoleProvider" cacheRolesInCookie="true" cookieName="RoleCookie" cookiePath="/" cookieTimeout="30" cookieRequireSSL="false" cookieSlidingExpiration="true" createPersistentCookie="false" cookieProtection="All">
      <providers>
        <clear />
        <add name="ActiveDirectoryRoleProvider" connectionStringName="ADServices" connectionUsername="" connectionPassword="" attributeMapUsername="sAMAccountName" type="" />
      </providers>
    </roleManager>

    <membership defaultProvider="MembershipADProvider">
      <providers>
        <add name="MembershipADProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" applicationName="" connectionStringName="ADServices" connectionUsername="" connectionPassword="" attributeMapUsername="sAMAccountName" />
      </providers>
    </membership>

<bindings>
  <webHttpBinding> <!-- webHttpBinding is for REST -->
    <binding name="TransportSecurity" maxReceivedMessageSize="5242880">
      <security mode="Transport">
      </security>
    </binding>
  </webHttpBinding>
</bindings>

<behaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp />
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehaviour">
      <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true" />
      <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true" />
      <serviceAuthorization principalPermissionMode="UseAspNetRoles" roleProviderName="ActiveDirectoryRoleProvider" />
      <serviceCredentials>
        <userNameAuthentication userNamePasswordValidationMode="MembershipProvider" membershipProviderName="MembershipADProvider" />
      </serviceCredentials>
    </behavior>
  </serviceBehaviors>
</behaviors>

代码

    public void SignIn2(string userName, bool createPersistentCookie)
    {
        if (String.IsNullOrEmpty(userName)) throw new ArgumentException("Value cannot be null or empty.", "userName");

        // put the attributes in a string for userdata
        string userData = "";

        // create the ticket
        FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1,
                                                userName,
                                                DateTime.Now,
                                                DateTime.Now.AddMinutes(240),
                                                createPersistentCookie,
                                                userData);

        // Now encrypt the ticket.
        string encryptedTicket = FormsAuthentication.Encrypt(authTicket);

        // Create a cookie and add the encrypted ticket to the cookie as data.
        HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);

        // add the cookie
        HttpContext.Current.Response.Cookies.Add(authCookie);
    }

现在使用Principal Permission ,我得到SecurityException(我知道该角色在服务器上有效)

    [PrincipalPermission(SecurityAction.Demand, Role = Constants.RoleUser)]
    public Message TestRoles()
    {
        var context = NetworkHelper.GetWebOperationContext();

        return context.CreateTextResponse("You have successfully activated the endpoint.");
    }

我错过了关键的一步吗?

我写了关于如何在WCF中使用ASP.NET身份验证的a blog post;它的要点是你想使用以下绑定:

  <basicHttpBinding>
    <binding>
      <security mode="TransportWithMessageCredential">
        <message clientCredentialType="UserName"/>
      </security>
    </binding>
  </basicHttpBinding>

您还必须应用以下serviceBehavior

    <behavior>
      <!-- no need for http get;
          but https get exposes endpoint over SSL/TLS-->
      <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/>
      <!-- the authorization and credentials elements tie
        this behavior (defined as the default behavior) to
        the ASP.NET membership framework-->
      <serviceAuthorization
          principalPermissionMode="UseAspNetRoles"
          roleProviderName="AspNetRoleProvider" />
      <serviceCredentials>
        <userNameAuthentication
            userNamePasswordValidationMode="MembershipProvider"
            membershipProviderName="AspNetMembershipProvider" />
      </serviceCredentials>
    </behavior>

需要注意的一点是,如果要使用名称和密码保护WCF,则必须使用SSL,这就是指定传输安全性的原因。

完成此操作后,您应该可以使用PrincipalPermission属性来保护您的服务方法。

很久以前,我和校长有类似的问题。我不记得细节了,但是从我很老的项目中试试这个:

我。你必须添加2个辅助类:


using System.Web;
using System.IdentityModel.Claims;
using System.IdentityModel.Policy;

namespace TicketingCore
{
    public class HttpContextPrincipalPolicy : IAuthorizationPolicy
    {
        public bool Evaluate(EvaluationContext evaluationContext, ref object state)
        {
            HttpContext context = HttpContext.Current;

            if (context != null)
            {
                evaluationContext.Properties["Principal"] = context.User;
            }

            return true;
        }

        public System.IdentityModel.Claims.ClaimSet Issuer
        {
            get { return ClaimSet.System; }
        }

        public string Id
        {
            get { return "TicketingCore HttpContextPrincipalPolicy"; }
        }
    }
} 


using System;
using System.Collections.Generic;
using System.IdentityModel.Claims;
using System.IdentityModel.Policy;
using System.Text;
using System.Web;
using System.Security.Principal;

namespace TicketingCore
{
    // syncs ServiceSecurityContext.PrimaryIdentity in WCF with whatever is set 
    // by the HTTP pipeline on Context.User.Identity (optional)
    public class HttpContextIdentityPolicy : IAuthorizationPolicy
    {
        public bool Evaluate(EvaluationContext evaluationContext, ref object state)
        {
            HttpContext context = HttpContext.Current;

            if (context != null)
            {
                // set the identity (for PrimaryIdentity)
                evaluationContext.Properties["Identities"] = 
                    new List<IIdentity>() { context.User.Identity };

                // add a claim set containing the client name
                Claim name = Claim.CreateNameClaim(context.User.Identity.Name);
                ClaimSet set = new DefaultClaimSet(name);
                evaluationContext.AddClaimSet(this, set);
            }

            return true;
        }

        public System.IdentityModel.Claims.ClaimSet Issuer
        {
            get { return ClaimSet.System; }
        }

        public string Id
        {
            get { return "TicketingCore HttpContextIdentityPolicy"; }
        }
    }
}

II。更改webconfig以添加这两个策略,这是我的配置(格式:add policyType =“namespace.class,assembly”)

<serviceBehaviors>
    <behavior name="ServiceBehavior">
      <serviceCredentials>
        <userNameAuthentication userNamePasswordValidationMode="MembershipProvider" membershipProviderName="SQLMembershipProvider"/>
      </serviceCredentials>
      <serviceAuthorization principalPermissionMode="Custom">
        <authorizationPolicies>
          <add policyType="TicketingCore.HttpContextIdentityPolicy, TicketingCore"/>
          <add policyType="TicketingCore.HttpContextPrincipalPolicy, TicketingCore"/>
        </authorizationPolicies>
      </serviceAuthorization>
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>

III。确保cookie和角色正常运行

注意:我也不记得解决方案的来源,你可能需要谷歌的类名来查找,希望对你有所帮助,祝你好运!

答案 2 :(得分:2)

我认为这样的事情会提供你想要的东西:

// Only members of the SpecialClients group can call this method.
[PrincipalPermission(SecurityAction.Demand, Role = "SpecialClients")]
public void DoSomething()
{ 
}

您可以在此处找到有关设置服务的不同选项的好文章:MSDN Article。您可能希望使用以下内容更新配置:

<security mode="TransportWithMessageCredential" >
    <transport clientCredentialType="Windows" />
</security>

两年前,我在博客上发表了与表单身份验证和主要权限属性的wcf集成。我相信你会觉得这很有用:

答案 4 :(得分:1)

查看此问题Passing FormsAuthentication cookie to a WCF service。重点是由于cookie域/ asp设置/ auth加密密钥,无法发送或接收验证cookie。我建议您为了调试目的而转储该cookie值Request.Cookies [“。ASPXAUTH”]。
