我正在使用 asp.net 核心1.1和身份1.1。我的应用程序中有 2 个角色包含"管理员"和"用户"。我希望"管理员"用户在登录后导航到"/AdminProfile/Index","用户"用户在登录后导航到"/UserProfile/Index"。
我的登录代码 :
[HttpGet]
public IActionResult Login(string returnUrl = null)
{
ViewData["ReturnUrl"] = returnUrl;
return View();
}
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null)
{
ViewData["ReturnUrl"] = returnUrl;
if (ModelState.IsValid)
{
var result = await _signInManager.PasswordSignInAsync(model.UserName, model.Password, model.RememberMe, lockoutOnFailure: false);
if (result.Succeeded)
{
return RedirectToLocal(returnUrl);
}
else
{
ModelState.AddModelError(string.Empty, "Error");
return View(model);
}
}
return View(model);
}
在重定向到本地操作中:
private IActionResult RedirectToLocal(string returnUrl)
{
if (Url.IsLocalUrl(returnUrl))
{
return Redirect(returnUrl);
}
else
{
if (User.IsInRole("Admin"))
{
return Redirect("/AdminProfile/Index");
}
else
{
return Redirect("/UserProfile/Index");
}
}
}
我使用User.IsInRole("Admin")
来验证用户角色,但它总是返回 false。如何在标识 1.1 中检查用户角色?
经过多次研究,我可以解决它。试试吧 :
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null)
{
ViewData["ReturnUrl"] = returnUrl;
if (ModelState.IsValid)
{
var result = await _signInManager.PasswordSignInAsync(model.UserName, model.Password, model.RememberMe, lockoutOnFailure: false);
if (result.Succeeded)
{
var user = await _userManager.FindByNameAsync(model.UserName);
string existingRole = _userManager.GetRolesAsync(user).Result.Single();
return RedirectToLocal(returnUrl,existingRole);
}
else
{
ModelState.AddModelError(string.Empty, "Error");
return View(model);
}
}
return View(model);
}
private IActionResult RedirectToLocal(string returnUrl,string roleName)
{
if (Url.IsLocalUrl(returnUrl))
{
return Redirect(returnUrl);
}
else
{
if (roleName == "Admin")
{
return Redirect("/Admin/User");
}
else
{
return Redirect("/User/UserProfile");
}
}
}
