ASP.NET MVC5身份：避免在注册后更改登录用户

Question

我想更改MVC5 ASP.NET Application的默认注册操作。我的情况是，授权用户（如admin）将登录并且可以创建新用户。然而，使用下面的代码片段，创建用户后，当前登录用户将更改为注册用户。

如何更改以下代码以避免更改登录用户？

// POST: /Account/Register 
[HttpPost] 
[AllowAnonymous] 
[ValidateAntiForgeryToken] 
public async Task<ActionResult> Register(RegisterViewModel model) 
{ 
    if (ModelState.IsValid) 
    { 
     var user = new ApplicationUser() { UserName = model.UserName,Name=model.Name }; 
     var result = await UserManager.CreateAsync(user, model.Password); 
     if (result.Succeeded) 
     { 
      await SignInAsync(user, isPersistent: false); 
      return RedirectToAction("Index", "Home"); 
     } 
     else 
     { 
      AddErrors(result); 
     } 
    } 

    // If we got this far, something failed, redisplay form 
    return View(model); 
} 

Answer 1

删除SignInAsync并添加[授权]注释：

[HttpPost] 
[Authorize] 
[ValidateAntiForgeryToken] 
public async Task<ActionResult> Register(RegisterViewModel model) 
{ 
    if (ModelState.IsValid) 
    { 
     var user = new ApplicationUser() { UserName = model.UserName,Name=model.Name }; 
     var result = await UserManager.CreateAsync(user, model.Password); 
     if (result.Succeeded) 
     { 
      //await SignInAsync(user, isPersistent: false); 
      return RedirectToAction("Index", "Home"); 
     } 
     else 
     { 
      AddErrors(result); 
     } 
    } 

    // If we got this far, something failed, redisplay form 
    return View(model); 
}

只要做到这一点：

if (result.Succeeded) 
{ 
    if (!User.IsAuthenticated) // if they're already logged in, don't log in again 
     await SignInAsync(user, isPersistent: false); 
    return RedirectToAction("Index", "Home"); 
}
