WCF Membership and Role Provider

本文介绍的是如何使用Membership 和 Role Provider 来控制 WCF 调用方法的权限。

比如我们有一个WCF Method 叫 GetData(int num),然后我们只允许Role = "Administrator"的用户来调用它，这就是本文要介绍的。

首先，我们先建立一个Solution，Solution里面有两个Project,一个是我们的WCF Service叫MyService,另外是一个客户端的Web Project,叫 MyClientApp, 在MyClientApp下有个Default.aspx，来调用MyService.

 

里面的MyService是默认建立的WCF Service,这里我们不介绍如何写一个简单的WCF 程序。

重要的是，在我们的方法GetData(int value)上加上这么一句话

1. [PrincipalPermission(SecurityAction.Demand, Role = "Administrator")]

意思是我们只允许Administrator Role的用户来调用GetDate这个方法

整个的代码为

1. [PrincipalPermission(SecurityAction.Demand, Role = "Administrator")]
2.        public string GetData(int value)
3.        {
4.            return string.Format("You entered: {0}", value);
5.        }

 

 

当运行Default.aspx的时候，我们看到这样的结果。

 

aspnet_regsql建立Membership 数据库。

完成后修改MyService里面的Web.config，在这里一定看好，不是MyClientApp,而是MyService的web.config

添加如下

1. <connectionStrings>
2.     <add name="WCFDemoConnection"
3.          connectionString="Data Source=localhost;Initial Catalog=WCFDemo;User ID=sa;Password=9ijn)OKM;"
4.          providerName="Sql.Data.SqlClient" />
5.   </connectionStrings>

 

1. <roleManager enabled="true" defaultProvider="AspNetSqlRoleProvider" >
2.       <providers>
3.         <remove name="AspNetSqlRoleProvider" />
4.         <remove name="AspNetWindowsTokenRoleProvider" />
5.         <add connectionStringName="WCFDemoConnection"
6.              applicationName="WCFDemo"
7.              name="AspNetSqlRoleProvider"
8.              type="System.Web.Security.SqlRoleProvider" />
9.       </providers>
10.     </roleManager>
11.     <membership defaultProvider="AspNetSqlProvider" >
12.       <providers>
13.         <remove name="AspNetSqlMembershipProvider" />
14.         <add connectionStringName="WCFDemoConnection"
15.              applicationName="WCFDemo"
16.              minRequiredPasswordLength="2"
17.              minRequiredNonalphanumericCharacters="0"
18.              requiresQuestionAndAnswer="false"
19.              requiresUniqueEmail=" false"
20.              name="AspNetSqlProvider"
21.              type="System.Web.Security.SqlMembershipProvider "
22.              enablePasswordRetrieval="true"
23.              passwordFormat="Encrypted"
24.              maxInvalidPasswordAttempts="20"/>
25.       </providers>
26.     </membership>
27.     <machineKey validationKey="0D9EA75EE7CEF839CACB3DBAC68F420060EC381F315C2C12A80DBBBE7A8ED02079B8371B0654F11549248F58E55B5E74051DC888BA978BE1D733CF452511ECB7 " decryptionKey="BD9A8F945ACCB35EAB54542B771D34CFFE01F026A5FC5857A4253FAA20EA207F" validation="SHA1" decryption=" AES" />

 

 

 

选择MyService的Project,然后进入到ASP.NET Web Site Administration Tool的界面，在里面建立两个Role，一个Administrator,一个是User

然后我们在建立两个User,一个是Administrator group里面的admin,密码Password,一个是User group里面的user1,密码是Password

 

 

在MyServiceweb.config,进行修改，这里我们暂时不做Certificate Check, 所以我们使用NoCheck.

1. <behaviors>
2.  
3.       <serviceBehaviors>
4.  
5.         <behavior>
6.           <serviceAuthorization principalPermissionMode="UseAspNetRoles" roleProviderName="AspNetSqlRoleProvider">
7.           </serviceAuthorization>
8.           <serviceMetadata httpGetEnabled="true" />
9.           <serviceDebug includeExceptionDetailInFaults="false" />
10.           <serviceCredentials>
11.             <clientCertificate >
12.               <authentication certificateValidationMode="PeerOrChainTrust" revocationMode="NoCheck"/>
13.               <certificate findValue="localhost" storeLocation="LocalMachine" storeName="My" x509FindType="FindBySubjectName" />
14.             </clientCertificate>
15.             <serviceCertificate findValue="localhost" storeLocation="LocalMachine" storeName="My" x509FindType="FindBySubjectName" />
16.             <userNameAuthentication userNamePasswordValidationMode="MembershipProvider"
17.               membershipProviderName="AspNetSqlProvider" />
18.           </serviceCredentials>
19.         </behavior>
20.       </serviceBehaviors>
21.     </behaviors>

 

在MyClientApp端进，Add Reference,自动生成web.config，

进行测试，输入正确的用户名密码

1. try
2.            {
3.                ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
4.                client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;
5.                client.ClientCredentials.UserName.UserName = "admin";
6.                client.ClientCredentials.UserName.Password = "Password";
7.                Response.Write(client.GetData(5));
8.            }
9.            catch (Exception ex)
10.            {
11.                Response.Write(ex.Message);
12.            }

 

输入另外User group内User1,

1. try
2.             {
3.                 ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
4.                 client.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = System.ServiceModel.Security.X509CertificateValidationMode.None;
5.                 client.ClientCredentials.UserName.UserName = "user1";
6.                 client.ClientCredentials.UserName.Password = "Password";
7.                 Response.Write(client.GetData(5));
8.             }
9.             catch (Exception ex)
10.             {
11.                 Response.Write(ex.Message);
12.             }
