如何从UserProfile获取自定义信息
本文关键字:自定义 信息 获取 UserProfile | 更新日期: 2023-09-27 18:26:16
我在UserProfile中添加自定义字段UserType作为字符串。我想更改我的login post method to get the value from UserType
,并在TempData中传递此值。
这是我在AccountController上的代码:
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginModel model, string returnUrl)
{
if (ModelState.IsValid && WebSecurity.Login(model.UserName, model.Password, persistCookie: model.RememberMe))
{
var context = new UsersContext();
var currentUser = Membership.GetUser(User.Identity.Name);
string username = currentUser.UserName;
var user = context.UserProfiles.SingleOrDefault(u => u.UserName == username);
var userType = user.UserType;
TempData["UserType"] = user.UserName; //Taking UserType from User Profile to validate in _Layout
return RedirectToLocal(returnUrl);
}
// If we got this far, something failed, redisplay form
ModelState.AddModelError("", "The user name or password provided is incorrect.");
return View(model);
}
我对这个方法进行了调试,这是我所掌握的信息:
> **On WebSecurity.Login()** I can see the UserName and Password.
> **Var CurrentUser** I can't get the value from User.Identity.Name
> **string Username** This error is displayed *Object reference not set to an instance of an object*. Application crash.
有人能解决这个问题吗?我是ASP.NET的新手,但如果我实现自定义成员身份,它可能会起作用,你觉得呢?你能给我举个例子吗?谢谢大家。
此处的解决方案:
`[HttpPost][AllowAnonyment][ValidateAntiForgeryToken]public ActionResult登录(LoginModel模型,字符串returnUrl){if(ModelState.IsValid&&WebSecurity.Login(model.UserName,model.Password,persistCookie:model.ErememberMe)){var context=new UsersContext();var user=上下文。UserProfiles.Where(u=>u.UserName==model.UserName);var userType=用户。选择(m=>m.UserType);
TempData["UserType"] = user.UserName; //Taking UserType from User Profile to validate in _Layout
return RedirectToLocal(returnUrl);
}
// If we got this far, something failed, redisplay form
ModelState.AddModelError("", "The user name or password provided is incorrect.");
return View(model);
}`
这只是一个想法,以防我无法评论我的声誉,为什么不直接使用model.UserName
而不是使用var currentUser = Membership.GetUser(User.Identity.Name);
这背后的原因是,任何登录的人都将是其自身的当前用户,您可以从数据库中检索其详细信息。
更新
你可以使用
UserProfile User = udb.UserProfiles.Where(m => m.UserName == model.UserName).FirstOrDefault();
var userType=User.UserType; // this brings your UserType from database
// then you can use this as
TempData["UserType"]=userType;
希望这对你有帮助!
