[英]ASP.NET MVC4 c# : Get user roles
這是我用於Global.asax中的成員資格的代碼
protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
{
if (FormsAuthentication.CookiesSupported == true)
{
if (Request.Cookies[FormsAuthentication.FormsCookieName] != null)
{
try
{
//let us take out the username now
string username = FormsAuthentication.Decrypt(Request.Cookies[FormsAuthentication.FormsCookieName].Value).Name;
string roles = string.Empty;
IUserService _userService= new UserService();
UserViewModel user = _userService.SelectUserByUserName(username).UserList.FirstOrDefault();
roles = user.role;
//let us extract the roles from our own custom cookie
//Let us set the Pricipal with our user specific details
HttpContext.Current.User = new System.Security.Principal.GenericPrincipal(
new System.Security.Principal.GenericIdentity(username, "Forms"), roles.Split(','));
}
catch (Exception)
{
//somehting went wrong
}
}
}
}
我正在嘗試將用戶重定向到其他視圖(如果他的角色是“經理”),這是我試圖在控制器中獲取用戶角色的方法,但是它返回一個空列表:
[Authorize(Roles = "admin, manager")]
public ActionResult Index()
{
string[] rolesArray;
rolesArray = Roles.GetAllRoles();// returns an empty array
foreach(var item in rolesArray){
if(item == "manager"){
return RedirectToAction("index", "Manager");
}
}
return View();
}
您應該可以調用.IsInRole()
if (User.IsInRole("manager"))
{
return RedirectToAction("index", "Manager");
}
