asp.net-mvc – 在MVC中将值从Controller传输到Shared View

我需要从控制器发送一些值到共享视图以显示在顶部

[HttpPost]
    [Route("login")]
    public async Task<ActionResult> Login(LogInRequest logInRequest)
    {
        IEnumerable<UserClaim> UserClaims = null;
        User user = null;
        if (ModelState.IsValid)
        {
      user = await GetUserByEmailAndPassword(logInRequest.UserName,logInRequest.Password);
            if (user.Id != 0)
            {
                 showMenu = await ShowLoanMenu(logInRequest);
                if (showMenu)
                {
        ******** I need to send showMenu and user.Name to shared view
             return RedirectToAction(Constants.Views.SearchView,Constants.Views.LoanDriverController);
                }
            }
               .....
              return View(logInRequest);
    }

我不想使用TempData,viewdata,viewbag或session,我如何通过查询字符串或添加到模型来发送它.

这是布局之一：

<ul>
            <li class="logo">
                <img src="~/Content/Images/logo.png" alt="" />
            </li>
            <li class="nav-item">
                  ***  @if(showmenu is true)
                 {
                    <ul>
                        @Html.ActionLink("Loan Driver","Index","Home",new { area = "" },new { @class = "navbar-brand" })
                    </ul>
                }
            </li>
        </ul>

这是另一种布局：

<div class="header">
       <div class="master-container">
        <div class="heading">Garage</div>
        <div class="primary-nav">
            <ul>
                <li>******show name of the person</li>
                <li>@Html.ActionLink("Logout","logout","Home")</li>
               </ul>
           </div>
        </div>

解决方法

HttpContext.Items["UIOptions"] = new UIOptions { ShowMenu = true };

您可以使用扩展名对此进行抽象：

public static class HttpContextExtensions
    {
        public static UIOptions GetUIOptions(this HttpContext httpContext)
        {
            var options = httpContext.Items["UIOptions"] ?? (object) new UIOptions();
            httpContext.Items["UIOptions"] = options;
            return options;
        }
    }

然后在您的控制器中,设置选项

HttpContext.GetUIOptions().ShowMenu= true

在您的视图中,像这样访问它：

ViewContext.HttpContext.GetUIOptions()

我通常会进一步抽象,以便您使用类似的属性对其进行配置

[UIOptions(ShowMenu=true)]
public ActionResult MyAction()
{
    return View();
}

因此,您编写了一个ActionFilter,它检查操作的属性,并在ActionExecuting阶段使用属性属性设置httpContext.GetUIOptions()对象的属性.
