如您所见,我创建了一个 wcf 服务:
[OperationContract]
[PrincipalPermission(SecurityAction.Demand, Role = "Admin")]
[WebInvoke(Method = "GET", UriTemplate = "/Data/{data}")]
string GetData(string data);
所以我创建了一个自定义授权,如您所见:
public class AuthorizationPolicy : IAuthorizationPolicy
{
string id = Guid.NewGuid().ToString();
public string Id
{
get { return this.id; }
}
public System.IdentityModel.Claims.ClaimSet Issuer
{
get { return System.IdentityModel.Claims.ClaimSet.System; }
}
// this method gets called after the authentication stage
public bool Evaluate(EvaluationContext evaluationContext, ref object state)
{
// get the authenticated client identity
IIdentity client = HttpContext.Current.User.Identity;
// set the custom principal
evaluationContext.Properties["Principal"] = new CustomPrincipal(client);
return true;
}
}
public class CustomPrincipal : IPrincipal
{
private IIdentity _identity;
public IIdentity Identity
{
get
{
return _identity;
}
}
public CustomPrincipal(IIdentity identity)
{
_identity = identity;
}
public bool IsInRole(string role)
{
//my code
return true;
// return Roles.IsUserInRole(role);
}
}
和身份验证:
public class RestAuthorizationManager: ServiceAuthorizationManager
{
protected override bool CheckAccessCore(OperationContext operationContext)
{
//Extract the Authorization header, and parse out the credentials converting the Base64 string:
var authHeader = WebOperationContext.Current.IncomingRequest.Headers["Authorization"];
if ((authHeader != null) && (authHeader != string.Empty))
{
var svcCredentials = System.Text.ASCIIEncoding.ASCII
.GetString(Convert.FromBase64String(authHeader.Substring(6)))
.Split(':');
var user = new
{
Name = svcCredentials[0],
Password = svcCredentials[1]
};
if ((user.Name == "1" && user.Password == "1"))
{
//here i get the role of my user from the database
// return Admin role
//User is authrized and originating call will proceed
return true;
}
else
{
//not authorized
return false;
}
}
else
{
//No authorization header was provided, so challenge the client to provide before proceeding:
WebOperationContext.Current.OutgoingResponse.Headers.Add("WWW-Authenticate: Basic realm=\"MyWCFService\"");
//Throw an exception with the associated HTTP status code equivalent to HTTP status 401
throw new WebFaultException(HttpStatusCode.Unauthorized);
}
}
}
所以我在我的 IIS 中创建和 https 托管并上传服务,我的身份验证类正在工作,但我的授权没有。为什么?我在我的 Web 配置中定义了我的身份验证,如您所见。但我没有知道如何在我的网络配置中定义我的授权。

我的意思是,当我在客户端调用我的服务时。该服务不检查授权功能。我应该在 webconfig 中定义我的自定义授权类,但我不知道如何定义?
public bool IsInRole(string role)
{
//my code
return true;
// return Roles.IsUserInRole(role);
}
最佳答案
您可能需要在 web config
文件中设置 serviceCredentials
:
<serviceCredentials type="YourString">
<YourTagsHere>
</YourTagsHere>
</serviceCredentials>
