问题描述
我在用ASP.net MVC4自定义角色提供程序的问题。我实现了一个重量很轻的RoleProvider这似乎做工精细的权利，直到我换
[授权]
公共类BlahController：....
}
到
[授权（角色=管理员）]
公共类BlahController：....
}
只要我做出的改变用户不再验证，我得到401错误。这是奇怪，因为我基本上RoleProvider为返回的isUserInRole和含有GetUserRoles将管理员列表真。我曾在地方断点在我的自定义RoleProvider每一个方法，发现他们无一被调用。
接下来我实现了从AuthorizeAttribute继承了我自己的授权属性。在此我把破发点，所以我可以看到发生了什么事情。原来，User.IsInRole（），它是由基础属性被称为返回false。
我相信，角色提供的设置是否正确。我有这个在我的配置文件
＆LT; roleManager启用=真正的defaultProvider =SimplicityRoleProvider＆GT;
＆LT;供应商＆GT;
＆LT;清/＆GT;
＆LT;添加名称=SimplicityRoleProviderTYPE =Simplicity.Authentication.SimplicityRoleProvider的applicationName =简单/＆GT;
＆LT; /供应商＆GT;
＆LT; / roleManager＆GT;
和检查哪个角色提供程序是当前使用的方法描述如下：参考电流RoleProvider例如产生正确的结果。然而User.IsInRole坚持返回false。
我使用Azure的访问控制服务，但我看不出这将是一个自定义角色提供程序不兼容。
我能做些什么来纠正用户的IPrincipal这样IsInRole返回从我的自定义RoleProvider的价值？

似乎System.Web.Security.Roles.GetRolesForUser（用户名）不会被自动挂接，当你有一个自定义AuthorizeAttribute和一个自定义RoleProvider。
那么，在您的自定义AuthorizeAttribute你需要从数据源中检索角色列表，然后比较他们对作为参数传递给AuthorizeAttribute的角色。
我看到一对夫妇的博客文章评论暗示手动比较的角色是没有必要的，但是当我们覆盖AuthorizeAttribute看来，我们是燮pressing这种行为，需要向它提供自己。
无论如何，我会通过我什么工作走。希望这会有些帮助的。
我欢迎是否有更好的方式来做到这一点的意见。
请注意，在我的情况下，AuthorizeAttribute被应用于ApiController虽然我不知道这是一个相关的资料片。

I'm having an issue with a custom role provider in ASP.net MVC4. I implemented a very light weight RoleProvider which seems to work fine right up until I change
[Authorize]
public class BlahController:....
}
to
[Authorize(Roles="Administrator")]
public class BlahController:....
}
as soon as I make that change users are no longer authenticated and I get 401 errors. This is odd because my RoleProvider basically returns true for IsUSerInRole and a list containing "Administrator" for GetUserRoles. I had breakpoints in place on every method in my custom RoleProvider and found that none of them were being called.
Next I implemented my own authorize attribute which inherited from AuthorizeAttribute. In this I put in break points so I could see what was going on. It turned out that User.IsInRole(), which is called by the underlying attribute was returning false.
I am confident that the role provider is properly set up. I have this in my config file
<roleManager enabled="true" defaultProvider="SimplicityRoleProvider">
<providers>
<clear />
<add name="SimplicityRoleProvider" type="Simplicity.Authentication.SimplicityRoleProvider" applicationName="Simplicity" />
</providers>
</roleManager>
and checking which role provider is the current one using the method described here: Reference current RoleProvider instance? yields the correct result. However User.IsInRole persists in returning false.
I am using Azure Access Control Services but I don't see how that would be incompatible with a custom role provider.
What can I do to correct the IPrincipal User such that IsInRole returns the value from my custom RoleProvider?
RoleProvider source:
public class SimplicityRoleProvider : RoleProvider { private ILog log { get; set; }
public SimplicityRoleProvider()
{
log = LogManager.GetLogger("ff");
}
public override void AddUsersToRoles(string[] usernames, string[] roleNames)
{
log.Warn(usernames);
log.Warn(roleNames);
}
public override string ApplicationName
{
get
{
return "Simplicity";
}
set
{
}
}
public override void CreateRole(string roleName)
{
}
public override bool DeleteRole(string roleName, bool throwOnPopulatedRole)
{
return true;
}
public override string[] FindUsersInRole(string roleName, string usernameToMatch)
{
log.Warn(roleName);
log.Warn(usernameToMatch);
return new string[0];
}
public override string[] GetAllRoles()
{
log.Warn("all roles");
return new string[0];
}
public override string[] GetRolesForUser(string username)
{
log.Warn(username);
return new String[] { "Administrator" };
}
public override string[] GetUsersInRole(string roleName)
{
log.Warn(roleName);
return new string[0];
}
public override bool IsUserInRole(string username, string roleName)
{
log.Warn(username);
log.Warn(roleName);
return true;
}
public override void RemoveUsersFromRoles(string[] usernames, string[] roleNames)
{
}
public override bool RoleExists(string roleName)
{
log.Warn(roleName);
return true;
}
}
It seems that System.Web.Security.Roles.GetRolesForUser(Username) does not get automatically hooked up when you have a custom AuthorizeAttribute and a custom RoleProvider.
So, in your custom AuthorizeAttribute you need to retrieve the list of roles from your data source and then compare them against the roles passed in as parameters to the AuthorizeAttribute.
I have seen in a couple blog posts comments that imply manually comparing roles is not necessary but when we override AuthorizeAttribute it seems that we are suppressing this behavior and need to provide it ourselves.
Anyway, I'll walk through what worked for me. Hopefully it will be of some assistance.
I welcome comments on whether there is a better way to accomplish this.
Note that in my case the AuthorizeAttribute is being applied to an ApiController although I'm not sure that is a relevant piece of information.
public class RequestHashAuthorizeAttribute : AuthorizeAttribute
{
bool requireSsl = true;
public bool RequireSsl
{
get { return requireSsl; }
set { requireSsl = value; }
}
bool requireAuthentication = true;
public bool RequireAuthentication
{
get { return requireAuthentication; }
set { requireAuthentication = value; }
}
public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext ActionContext)
{
if (Authenticate(ActionContext) || !RequireAuthentication)
{
return;
}
else
{
HandleUnauthorizedRequest(ActionContext);
}
}
protected override void HandleUnauthorizedRequest(HttpActionContext ActionContext)
{
var challengeMessage = new System.Net.Http.HttpResponseMessage(HttpStatusCode.Unauthorized);
challengeMessage.Headers.Add("WWW-Authenticate", "Basic");
throw new HttpResponseException(challengeMessage);
}
private bool Authenticate(System.Web.Http.Controllers.HttpActionContext ActionContext)
{
if (RequireSsl && !HttpContext.Current.Request.IsSecureConnection && !HttpContext.Current.Request.IsLocal)
{
//TODO: Return false to require SSL in production - disabled for testing before cert is purchased
//return false;
}
if (!HttpContext.Current.Request.Headers.AllKeys.Contains("Authorization")) return false;
string authHeader = HttpContext.Current.Request.Headers["Authorization"];
IPrincipal principal;
if (TryGetPrincipal(authHeader, out principal))
{
HttpContext.Current.User = principal;
return true;
}
return false;
}
private bool TryGetPrincipal(string AuthHeader, out IPrincipal Principal)
{
var creds = ParseAuthHeader(AuthHeader);
if (creds != null)
{
if (TryGetPrincipal(creds[0], creds[1], creds[2], out Principal)) return true;
}
Principal = null;
return false;
}
private string[] ParseAuthHeader(string authHeader)
{
if (authHeader == null || authHeader.Length == 0 || !authHeader.StartsWith("Basic")) return null;
string base64Credentials = authHeader.Substring(6);
string[] credentials = Encoding.ASCII.GetString(Convert.FromBase64String(base64Credentials)).Split(new char[] { ':' });
if (credentials.Length != 3 || string.IsNullOrEmpty(credentials[0]) || string.IsNullOrEmpty(credentials[1]) || string.IsNullOrEmpty(credentials[2])) return null;
return credentials;
}
private bool TryGetPrincipal(string Username, string ApiKey, string RequestHash, out IPrincipal Principal)
{
Username = Username.Trim();
ApiKey = ApiKey.Trim();
RequestHash = RequestHash.Trim();
//is valid username?
IUserRepository userRepository = new UserRepository();
UserModel user = null;
try
{
user = userRepository.GetUserByUsername(Username);
}
catch (UserNotFoundException)
{
throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.Unauthorized));
}
//is valid apikey?
IApiRepository apiRepository = new ApiRepository();
ApiModel api = null;
try
{
api = apiRepository.GetApi(new Guid(ApiKey));
}
catch (ApiNotFoundException)
{
throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.Unauthorized));
}
if (user != null)
{
//check if in allowed role
bool isAllowedRole = false;
string[] userRoles = System.Web.Security.Roles.GetRolesForUser(user.Username);
string[] allowedRoles = Roles.Split(','); //Roles is the inherited AuthorizeAttribute.Roles member
foreach(string userRole in userRoles)
{
foreach (string allowedRole in allowedRoles)
{
if (userRole == allowedRole)
{
isAllowedRole = true;
}
}
}
if (!isAllowedRole)
{
throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.Unauthorized));
}
Principal = new GenericPrincipal(new GenericIdentity(user.Username), userRoles);
Thread.CurrentPrincipal = Principal;
return true;
}
else
{
Principal = null;
throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.Unauthorized));
}
}
}
The custom authorize attribute is governing the following controller:
public class RequestKeyAuthorizeTestController : ApiController
{
[RequestKeyAuthorizeAttribute(Roles="Admin,Bob,Administrator,Clue")]
public HttpResponseMessage Get()
{
return Request.CreateResponse(HttpStatusCode.OK, "RequestKeyAuthorizeTestController");
}
}
In the custom RoleProvider, I have this method:
public override string[] GetRolesForUser(string Username)
{
IRoleRepository roleRepository = new RoleRepository();
RoleModel[] roleModels = roleRepository.GetRolesForUser(Username);
List<string> roles = new List<string>();
foreach (RoleModel roleModel in roleModels)
{
roles.Add(roleModel.Name);
}
return roles.ToArray<string>();
}
这篇关于自RoleProvider失败时施加作用AuthorizeAttribute的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
