WCF身份验证-在验证消息的安全性时发生错误

本文关键字:安全性 错误 消息 身份验证 验证 WCF | 更新日期: 2023-09-27 18:07:31

我与clientCredentialType="UserName"连接WCF服务有问题。

当我运行下面的代码,我得到一个错误

FaultException: a error occurred when verify for the message.

当使用一些绑定值时,我也得到Access is denied.

Fiddler说没有授权头,我也无法在请求中找到用户名或密码。

以下是我的配置摘录:

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
    <services>
      <service name="InventoryServices.MobileAPI"  behaviorConfiguration="customBehaviour">
        <endpoint address=""
                  binding="basicHttpBinding"
                  bindingConfiguration="secureHttpBinding"
                  contract="InventoryServices.IMobileAPI"/>
        <endpoint address="mex"
                  binding="mexHttpsBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="customBehaviour">
          <serviceSecurityAudit auditLogLocation="Application" serviceAuthorizationAuditLevel="Failure" messageAuthenticationAuditLevel="Failure" suppressAuditFailure="true" />
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpsGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="Custom"
               customUserNamePasswordValidatorType="InventoryLibrary.Helpers.UserAuthentication,InventoryLibrary"/>
          </serviceCredentials>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <bindings>
      <basicHttpBinding>
        <binding name="secureHttpBinding">
          <security mode="TransportWithMessageCredential">
            <transport clientCredentialType="Basic" proxyCredentialType="Basic" realm="MyRealm"/>
            <message clientCredentialType="UserName" algorithmSuite="Default"  />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>

我的用户名/密码验证器看起来像这样:

  public class UserAuthentication : UserNamePasswordValidator {
        public override void Validate(string userName, string password) {
            EntitiesContext db = new EntitiesContext();
            db.Logs.Add(new DomainModels.Log() {
                DateLogged = DateTime.Now,
                Message = "hit auth",
                Type = DomainModels.LogType.Info
            });
            db.SaveChanges();
            try {
                if (userName == "test" && password == "test123") {
                    Console.WriteLine("Authentic User");
                }
            }
            catch (Exception ex) {
                throw new FaultException("Unknown Username or Incorrect Password");
            }
        }
    }

我在我的服务上做了一个简单的测试:

[OperationContract]
[XmlSerializerFormat]
void Test();
[PrincipalPermission(SecurityAction.Demand, Name = "test")]
public void Test() {
}

我的服务器上有一个自签名SSL证书,我可以访问我的服务/元数据。

然后我在控制台应用程序中添加了一个服务引用,并尝试使用下面的代码连接到服务:
class Program {
    static void Main(string[] args) {
        Stuff.InitiateSSLTrust();
        BasicHttpBinding binding = new BasicHttpBinding();
        binding.Security.Mode = BasicHttpSecurityMode.Transport;
        binding.Security.Transport.Realm = "MyRealm";
        ServiceReference1.MobileAPIClient serviceProxy = new ServiceReference1.MobileAPIClient(binding, new EndpointAddress("https://xx.xx.xx.xx/InventoryServices.MobileApi.svc"));
        serviceProxy.ClientCredentials.UserName.UserName = "test";
        serviceProxy.ClientCredentials.UserName.Password = "test123";
        try {
            var a = serviceProxy.Login("a", "b");
        }
        catch (Exception ex) {
            var ex2 = ex;
        }
    }
}
public class Stuff {
    public static void InitiateSSLTrust() {
        try {
            //Change SSL checks so that all checks pass
            ServicePointManager.ServerCertificateValidationCallback =
                new RemoteCertificateValidationCallback(
                    delegate { return true; }
                );
        }
        catch (Exception ex) {
        }
    }
}

我已经检查了服务器上的事件查看器,每个请求都出现这个错误:

MessageSecurityException:安全处理器无法在消息中找到安全标头。这可能是因为消息是不安全的错误,或者因为通信双方之间存在绑定不匹配。如果服务配置了安全性,而客户端没有使用安全性,则可能发生这种情况。

WCF身份验证-在验证消息的安全性时发生错误

您指定客户端使用BasicHttpSecurityMode.Transport,而服务期望使用BasicHttpSecurityMode.TransportWithMessageCredential。这是一个问题,因为服务正在SOAP消息头中查找客户端凭据,并且客户端不会以这种方式配置绑定发送它们。

因此,这就是为什么用户名/密码对没有出现在您所看到的消息头中。因此,事件查看器是正确的,通信双方之间存在绑定不匹配。

对于Message级别的安全,也将客户端的ClientCredentialType设置为BasicHttpMessageCredentialType.UserName。默认情况下,BasicHttpBinding使用的是匿名客户端None

下面是描述上述更改的代码片段:

var basicHttpBinding = new BasicHttpBinding(
                              BasicHttpSecurityMode.TransportWithMessageCredential);
basicHttpBinding.Security.Message.ClientCredentialType = 
                                     BasicHttpMessageCredentialType.UserName;

这也可能是由于客户机和服务器之间的时间不同步造成的。如果证书或签名令牌基于时间无效,则可能返回相同的An error occurred when verifying security for the message.消息。

在添加服务引用并从4.4中指向这些依赖项后编辑.csproj文件。*到4.6.*

<ItemGroup> <PackageReference Include="System.ServiceModel.Duplex" Version="4.6.*" /> 
    <PackageReference Include="System.ServiceModel.Http" Version="4.6.*" /> 
    <PackageReference Include="System.ServiceModel.NetTcp" Version="4.6.*" /> 
    <PackageReference Include="System.ServiceModel.Security" Version="4.6.*" /> 
</ItemGroup>

并加上

 binding.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.TransportWithMessageCredential;
 binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
