使用clientCredentialType="UserName"
连接WCF服务时,我遇到了问题。
当我运行下面的代码时,出现了以下错误:
FaultException: 验证消息的安全性时发生错误。
当我尝试更改一些绑定值时,还会出现拒绝访问
的错误。
Fiddler显示没有授权标头,请求中也找不到用户名或密码。
这是我的配置文件的摘录:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
<services>
<service name="InventoryServices.MobileAPI" behaviorConfiguration="customBehaviour">
<endpoint address=""

<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>
我的用户名/密码验证器如下所示:
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");
}
}
}
我在我的服务中有一个简单的测试:
[OperationContract]
[XmlSerializerFormat]
void Test();
[PrincipalPermission(SecurityAction.Demand, Name = "test")]
public void Test() {
}
我的服务器上有一个自签名的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,并尝试使用以下代码连接到服务:
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) {
}
}
}
我在服务器上检查了事件查看器,发现每个请求都出现了这个错误:
MessageSecurityException: 安全处理程序无法在消息中找到安全头。这可能是因为消息是一个未安全化的 fault,或者由于通信双方之间的绑定不匹配。如果服务配置为安全性,而客户端没有使用安全性,则可能会出现此问题。
