wcf 配置总结

最近在配置WCF的时候，需要一点麻烦，避免以后才出现错误，特记录起来

1.wcf需要使用用户名和X509证书验证

A.服务器的config配置

  a.bindings/binding中使用

<security mode="Message">
      <transport clientCredentialType="Windows" />
      <message clientCredentialType="UserName" />
     </security>

说明: mode等于Message可以不用https方式。

b.service中 <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />中，需要确认binding是否为http

说明: http的binding为mexHttpBinding，而https的binding为mexHttpsBinding

c.behaviors/serviceBehaviors/behavior需要设置证书的位置

<serviceCertificate findValue="CnServer" storeLocation="LocalMachine"
    x509FindType="FindBySubjectName" />

d.behaviors/serviceBehaviors/behavior需要设置使用的方式。 http就是使用 httpGetEnabled

<serviceMetadata httpGetEnabled="true" />

B.客户端的config配置

a.bindings/binding下面配置为

<security mode="Message">
      <transport clientCredentialType="Windows" proxyCredentialType="None"
       realm="" />
      <message clientCredentialType="UserName" negotiateServiceCredential="true"
       establishSecurityContext="true" />
     </security>

b.如果你有一个真正的X509证书，那么现在的代码就可以正常运行了。但是很不幸，我们的证书是测试用的，我们运行的时候出错：'X.509 certificate CN=MyServerCert 链生成失败。所使用的证书具有无法验证的信任链。请替换该证书或更改 certificateValidationMode。已处理证书链，但是在不受信任提供程序信任的根证书中终止'，WCF无法验证测试证书的信任链，那我们要做的就是绕过这个信任验证，具体做法如下

<behaviors>
   <endpointBehaviors>
    <behavior name="myClientBehavior">
     <clientCredentials>
      <serviceCertificate>
       <authentication certificateValidationMode="Custom" customCertificateValidatorType="xxxxxx.MyX509Validator,xxxxx.TestApplication" />
      </serviceCertificate>
     </clientCredentials>
    </behavior>
   </endpointBehaviors>
  </behaviors>

c.客户端代码增加

 public class MyX509Validator : X509CertificateValidator     {

        /// <summary>         /// Validates a certificate.         /// </summary>         /// <param name="certificate">The certificate the validate.</param>         public override void Validate(X509Certificate2 certificate)         {             // validate argument             //if (certificate == null)             //    throw new ArgumentNullException("X509认证证书为空！");             //// check if the name of the certifcate matches             //if (certificate.SubjectName.Name != ConfigurationManager.AppSettings["CertName"])             //    throw new SecurityTokenValidationException("Certificated was not issued by thrusted issuer");             return;         }

    }

2.wcf需要使用SSL及证书

A.服务器的config配置

a.bindings/binding中使用

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

说明: mode使用Transport，TransportWithMessageCredential必须是https方式。

b.service中 <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />中，需要确认binding是否为https

说明: http的binding为mexHttpBinding，而https的binding为mexHttpsBinding

c.behaviors/serviceBehaviors/behavior需要设置证书的位置

<serviceCertificate findValue="CnServer" storeLocation="LocalMachine"     x509FindType="FindBySubjectName" />

d.behaviors/serviceBehaviors/behavior需要设置使用的方式。 http就是使用 httpsGetEnabled

<serviceMetadata httpsGetEnabled="true" />

B.客户端的config配置

a.bindings/binding下面配置为

<security mode="TransportWithMessageCredential">
      <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
      <message clientCredentialType="UserName" negotiateServiceCredential="true"
                            algorithmSuite="Default" establishSecurityContext="true" />
     </security>

b.如果你有一个真正的X509证书，那么现在的代码就可以正常运行了。但是很不幸，我们的证书是测试用的，我们运行的时候出错：'X.509 certificate CN=MyServerCert 链生成失败。所使用的证书具有无法验证的信任链。请替换该证书或更改 certificateValidationMode。已处理证书链，但是在不受信任提供程序信任的根证书中终止'，WCF无法验证测试证书的信任链，那我们要做的就是绕过这个信任验证，具体做法如下

<behaviors>    <endpointBehaviors>     <behavior name="myClientBehavior">      <clientCredentials>       <serviceCertificate>        <authentication certificateValidationMode="Custom" customCertificateValidatorType="xxxxxx.MyX509Validator,xxxxx.TestApplication" />       </serviceCertificate>      </clientCredentials>     </behavior>    </endpointBehaviors>   </behaviors>

c.客户端代码增加

public class MyX509Validator : X509CertificateValidator     {

        /// <summary>         /// Validates a certificate.         /// </summary>         /// <param name="certificate">The certificate the validate.</param>         public override void Validate(X509Certificate2 certificate)         {             // validate argument             //if (certificate == null)             //    throw new ArgumentNullException("X509认证证书为空！");             //// check if the name of the certifcate matches             //if (certificate.SubjectName.Name != ConfigurationManager.AppSettings["CertName"])             //    throw new SecurityTokenValidationException("Certificated was not issued by thrusted issuer");             return;         }

    }

d.客户端代码增加以下代码，在调用服务的时候，就先调用Util.SetCertificatePolicy();

 public static class Util     {         /// <summary>         /// Sets the cert policy.         /// </summary>         public static void SetCertificatePolicy()         {             ServicePointManager.ServerCertificateValidationCallback                        += RemoteCertificateValidate;         }

        /// <summary>         /// Remotes the certificate validate.         /// </summary>         private static bool RemoteCertificateValidate(            object sender, X509Certificate cert,             X509Chain chain, SslPolicyErrors error)         {             // trust any certificate!!!             System.Console.WriteLine("Warning, trust any certificate");             return true;         }     }
