目标：
１.客户端与服务器端通信使用x509证书验证，但不用客户端安装证书。只需要服务器端配置好证书即可。
２.验证使用用户名密码形式。
操作：
（这里的测试使用wcf项目模板缺省的服务，即只要新建一个使用vs2008自动生成的wcf项目就行了，
它会自动生成有一个GetData方法，我就用这个方法进行测试）
1.新建WCF服务应用程序.
1.1生成一个服务器证书：运行Visual Studio 2008 命令提示工具：
输入：makecert -r -pe -n "CN=MyServer" -sr LocalMachine -ss My -sky exchange执行。
-sr LocalMachine 请一定保存到LodcalMachine中.目的就是到时如果你部署这个wcf服务的时候可以让IIS找到证书，
反之，IIS会报找不到x509证书.
2.配置web.config文件：
这里要注意的是把storeLocation设为LocalMachine,原因也是到时需要部署的时候可以免掉很多麻烦，因为以后发布到iis时很可以不能正常验证到证书的私钥.
1: <system.serviceModel>
2: <bindings>
3: <wsHttpBinding>
4: <binding name="NewBinding0">
5: <security>
6: <message clientCredentialType="UserName" />
7: </security>
8: </binding>
9: </wsHttpBinding>
10: </bindings>
11: <services>
12: <service behaviorConfiguration="WcfService2.Service1Behavior"
13: name="WcfService2.Service1">
14: <endpoint address="" binding="wsHttpBinding" bindingConfiguration="NewBinding0"
15: contract="WcfService2.IService1">
16: </endpoint>
17: <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
18: </service>
19: </services>
20: <behaviors>
21: <serviceBehaviors>
22: <behavior name="WcfService2.Service1Behavior">
23: <serviceMetadata httpGetEnabled="true" />
24: <serviceDebug includeExceptionDetailInFaults="false" />
25: <serviceCredentials>
26: <clientCertificate>
27: <authentication certificateValidationMode="None" />
28: </clientCertificate>
29: <serviceCertificate findValue="MyServer" storeLocation="LocalMachine" x509FindType="FindBySubjectName" />
30: <userNameAuthentication userNamePasswordValidationMode="Custom"
31: customUserNamePasswordValidatorType="WcfService2.MyUserNamePasswordValidator,WcfService2" />
32: </serviceCredentials>
33: </behavior>
34: </serviceBehaviors>
35: </behaviors>
36: </system.serviceModel>
3.建造验证客户端用户名和密码的方法.
这里注意的是必须与web.config文件中的customUserNamePasswordValidatorType=中的内容一致，
格式是："命名空间.方法名,命名空间"
实际项目应用中这里应该是从数据库里确认用客是否合法。
1: namespace WcfService2
2: {
3: public class MyUserNamePasswordValidator : UserNamePasswordValidator
4: {
5: public override void Validate(string userName, string password)
6: {
7: if (userName != "jac" || password != "jac")
8: {
9: throw new SecurityTokenException("Unknown Username or Password");
10: }
11: }
12: }
13: }
至此，wcf服务配置完成。
4.新建一个asp.net项目，并添加服务引用这个wcf服务.
5.修改asp.net项目的web.config文件(一定要在引用wcf服务后）.
添加一个endpointBehaviors:
1: <behaviors>
2: <endpointBehaviors>
3: <behavior name="jacBehavior">
4: <clientCredentials>
5: <serviceCertificate>
6: <authentication certificateValidationMode="None" />
7: </serviceCertificate>
8: </clientCredentials>
9: </behavior>
10: </endpointBehaviors>
11: </behaviors>
然后让它生效,
1: <endpoint address="http://j-8de9be98d1184/Service1.svc" behaviorConfiguration="jacBehavior"
2: binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService1"
3: contract="ServiceReference1.IService1" name="WSHttpBinding_IService1">
以下是完整的asp.net客户端的web.config文件的system.serviceModel部份
1: <system.serviceModel>
2: <behaviors>
3: <endpointBehaviors>
4: <behavior name="jacBehavior">
5: <clientCredentials>
6: <serviceCertificate>
7: <authentication certificateValidationMode="None" />
8: </serviceCertificate>
9: </clientCredentials>
10: </behavior>
11: </endpointBehaviors>
12: </behaviors>
13: <bindings>
14: <wsHttpBinding>

23: enabled="false" />
24: <security mode="Message">

27: <message clientCredentialType="UserName" negotiateServiceCredential="true"
28: algorithmSuite="Default" establishSecurityContext="true" />
29: </security>
30: </binding>
31: </wsHttpBinding>
32: </bindings>
33: <client>
34: <endpoint address="http://j-8de9be98d1184/Service1.svc" behaviorConfiguration="jacBehavior"
35: binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IService1"
36: contract="ServiceReference1.IService1" name="WSHttpBinding_IService1">
37: <identity>
38: <certificate encodedValue="AwAAAAEA.....................eGtnWJsvtFQsEuzDYw==" />
39: </identity>
40: </endpoint>
41: </client>
42: </system.serviceModel>
6.调用.
1: ServiceReference1.Service1Client sc = new WebApplication1.ServiceReference1.Service1Client();
2: sc.ClientCredentials.UserName.UserName = "jac";
3: sc.ClientCredentials.UserName.Password = "jac";
4: Label1.Text = sc.GetData(22);
完成.
