Web Api 2基本Auth通用主体未设置

Question

我有以下代码来设置Generic Principal.

public class AuthenticationHandler: DelegatingHandler
{
    protected override System.Threading.Tasks.Task<HttpResponseMessage> SendAsync(HttpRequestMessage request,
                                                                                  CancellationToken cancellationToken)
    {
        var accessToken = request.Headers.Authorization;
        if (accessToken == null)
            return base.SendAsync(request, cancellationToken);

        // Catch an error with regards to the accessToken being invalid
        try
        {
            var formsAuthenticationTicket = FormsAuthentication.Decrypt(accessToken.Parameter);

            if (formsAuthenticationTicket == null)
                return base.SendAsync(request, cancellationToken);

            var data = formsAuthenticationTicket.UserData;
            var userData = JsonConvert.DeserializeObject<LoginRoleViewModel>(data);

            var identity = new GenericIdentity(userData.Id.ToString(), "Basic");

            var userRole = userData.Roles.ToArray();
            var principal = new GenericPrincipal(identity, userRole);
            Thread.CurrentPrincipal = principal;
            HttpContext.Current.User = principal;

        }
        catch (Exception ex)
        {
            var responseMessage = request.CreateResponse(HttpStatusCode.BadRequest, new { ex.Message }); // return ex for full stacktrace
            return Task<HttpResponseMessage>.Factory.StartNew(() => responseMessage);
        }

        return base.SendAsync(request, cancellationToken);
    }

}

以下是控制器的示例

[Authorize(Roles = "Administrator, Customers")]
[HttpGet("customers/{id}")]
public CustomerViewModel GetCustomer(string id)
{
    var param = AuthService.CheckPermission(Request, User, id);
    var customer = Db.Customers.Find(param);
    return Mapper.Map<CustomerViewModel>(customer);
}

这是我检查用户角色的地方

public int CheckPermission(HttpRequestMessage request, IPrincipal user, string param)
{
    if (user.IsInRole("Customers") || user.IsInRole("Dealerships"))
    {
        if (param == null || param != "me")
            throw new HttpResponseException(request.CreateErrorResponse(HttpStatusCode.Forbidden, "unauthorized request"));
        param = user.Identity.Name;
    }

    return Convert.ToInt32(param);
}

这在升级到Web Api 2和MVC 5之前完美运行？现在用户没有角色或身份,有什么改变,我不知道？

Answer 1

不知道为什么它不再起作用,但在Web API 2中,有一个HttpRequestContext带有Principal属性的新类,这就是你应该设置更新的类Principal.您可以从请求中访问上下文对象.

Answer 2

真的不确定为什么这个功能在多年的稳定性后发生了变化.

我们发现了以下工作

request.GetRequestContext().Principal = new GenericIdentity(userData.Id.ToString(), "Basic");

这也有效,IMO在美学上更令人愉悦,因为你没有设置功能的成员

HttpContext.Current.User = new GenericIdentity(userData.Id.ToString(), "Basic");
