使用MVC asp.net重定向到操作不起作用

Question

我有一个要求，在此我要使用Windows身份验证来验证用户。到那里为止，它工作得很好。但是，当我尝试重定向到各自的controllers时，它什么也没做。

下面是我的代码。

public ActionResult ValidateUser(string strUsername, string strPassword)
    {
        string strReturn = "";
        string strDbError = string.Empty;
        strUsername = strUsername.Trim();
        strPassword = strPassword.Trim();

        UserProviderClient ObjUMS = new UserProviderClient();            
        bool result = ObjUMS.AuthenticateUser(strUsername, strPassword, out strDbError);

        Session["isUserAuthenticated"] = result;

        if (result == true)
        {
            Session["isUserOutsideINDomain"] = true;
            Session["OutsideINDomainUsername"] = strUsername;
            //redirect to respective controller

            UMS ObjUMSDATA = new UMS();

            string strUserName = "";
            string strCurrentGroupName = "";
            int intCurrentGroupID = 0;

            strUserName = System.Web.HttpContext.Current.User.Identity.Name.Split('\\')[1];                
            _UMSUserName = strUserName;

            if (!string.IsNullOrEmpty(strUserName))
            {
                List<UMSGroupDetails> lstUMSGroupDetails = null;
                List<UMSLocationDetails> lstUMSLocationDetails = null;

                ObjUMSDATA.GetUMSGroups(strUserName, out strCurrentGroupName, out intCurrentGroupID, out lstUMSLocationDetails, out lstUMSGroupDetails);
                if (strCurrentGroupName != "" && intCurrentGroupID != 0)
                {
                    ViewBag.LoginUserName = strUserName.ToUpper();
                    ViewBag.CurrentGroupName = strCurrentGroupName;
                    ViewBag.CurrentGroupID = intCurrentGroupID;
                    ViewBag.GroupDetails = lstUMSGroupDetails;
                    ViewBag.LocationDetails = lstUMSLocationDetails;
                    TempData["Location"] = lstUMSLocationDetails;

                    TempData["strCurrentGroupName"] = strCurrentGroupName;
                    TempData.Keep();

                    if (strCurrentGroupName == "NEIQC_SAP_ENGINEER")
                    {
                        return RedirectToAction("Assign","App"); // here its not redirecting properly.
                    }
                    else if (strCurrentGroupName == "NEIQC_FIBER_ENGINEER")
                    {
                        return RedirectToAction("App", "Certify");
                    }
                    else if (strCurrentGroupName == "NEIQC_CMM")
                    {
                        return RedirectToAction("App", "Approver");
                    }
                }
                else
                {
                    return RedirectToAction("ErrorPage", "UnAuthorize");
                }
            }

        }
        else
        {
            strReturn = "Login UnSuccessful";
        }

        return Json(strReturn);
    }

请帮助为什么它不起作用

        routes.MapRoute(

}

您的路由配置无法区分您给定的两条路由，因为它们没有区别。另外，您的默认路由应始终位于末尾。请将路由配置更改为此：

注意，我更改了“分配”路由的网址，并在末尾移动了“默认”路由。

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Assign",
        url: "App/{action}/{id}",
        defaults: new { controller = "App", action = "Assign", id = UrlParameter.Optional }               
    );

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Login", id = UrlParameter.Optional }

    );

}

由于您正在使用AJAX调用控制器操作，因此显然RedirectToAction在那里不起作用，因为AJAX调用旨在保留在同一页面中。您应该为所有响应返回JSON字符串，并在客户端脚本上使用switch...case块或if条件来重定向到相应的动作，并使用location.href和@Url.Action()助手来生成URL字符串：< / p>

[HttpPost]
public ActionResult ValidateUser(string strUsername, string strPassword)
{
    string strReturn = "";
    string strDbError = string.Empty;
    strUsername = strUsername.Trim();
    strPassword = strPassword.Trim();

    UserProviderClient ObjUMS = new UserProviderClient();            
    bool result = ObjUMS.AuthenticateUser(strUsername, strPassword, out strDbError);

    Session["isUserAuthenticated"] = result;

    if (result == true)
    {
        Session["isUserOutsideINDomain"] = true;
        Session["OutsideINDomainUsername"] = strUsername;
        //redirect to respective controller

        UMS ObjUMSDATA = new UMS();

        string strUserName = "";
        string strCurrentGroupName = "";
        int intCurrentGroupID = 0;

        strUserName = System.Web.HttpContext.Current.User.Identity.Name.Split('\\')[1];                
        _UMSUserName = strUserName;

        if (!string.IsNullOrEmpty(strUserName))
        {
            List<UMSGroupDetails> lstUMSGroupDetails = null;
            List<UMSLocationDetails> lstUMSLocationDetails = null;

            ObjUMSDATA.GetUMSGroups(strUserName, out strCurrentGroupName, out intCurrentGroupID, out lstUMSLocationDetails, out lstUMSGroupDetails);
            if (strCurrentGroupName != "" && intCurrentGroupID != 0)
            {
                ViewBag.LoginUserName = strUserName.ToUpper();
                ViewBag.CurrentGroupName = strCurrentGroupName;
                ViewBag.CurrentGroupID = intCurrentGroupID;
                ViewBag.GroupDetails = lstUMSGroupDetails;
                ViewBag.LocationDetails = lstUMSLocationDetails;
                TempData["Location"] = lstUMSLocationDetails;

                TempData["strCurrentGroupName"] = strCurrentGroupName;
                TempData.Keep();

                // here you need to return string for success result
                return Json(strCurrentGroupName);
            }
            else
            {
                return Json("Error");
            }
        }

    }
    else
    {
        strReturn = "Login UnSuccessful";
    }

    return Json(strReturn);
}

AJAX通话

$.ajax({
    url: AppConfig.PrefixURL + "Home/ValidateUser",
    dataType: 'json',
    type: 'post',
    contentType: 'application/json',
    data: JSON.stringify(Values),
    processData: false,
    success: function (result) {
        switch (result) {
            case 'NEIQC_SAP_ENGINEER':
               location.href = '@Url.Action("Assign", "App")';
               break;
            case 'NEIQC_FIBER_ENGINEER':
               location.href = '@Url.Action("Certify", "App")';
               break;
            case 'NEIQC_CMM':
               location.href = '@Url.Action("Approver", "App")';
               break;
            case 'Error':
               location.href = '@Url.Action("ErrorPage", "UnAuthorize")';
               break;
            case 'Login UnSuccessful':
               // do something
               break;

            // other case options here

        }
    },
    error: function (xhr, status, err) {
        // error handling
    }
});

附加说明：

RouteConfig处理从最特定的路由到更通用的路由，因此Default路由必须在最后声明，并且自定义路由定义必须与默认路由不同。

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Assign",
        url: "App/{action}/{id}",
        defaults: new { controller = "App", action = "Assign", id = UrlParameter.Optional }               
    );

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Login", id = UrlParameter.Optional }
    );

}

Answer 3

所以您当前有一个像这样的ajax调用：

$.ajax({
    url: AppConfig.PrefixURL + "Home/ValidateUser",
    dataType: 'json',
    type: 'post',
    contentType: 'application/json',
    data: JSON.stringify(Values),
    processData: false,
    success: function () {
    },
    error: function () {

    }
});

这很好，但是目前成功不起作用。您有一个返回字符串的控制器方法

return Json(strReturn);

现在，我希望您不要返回该值，而是将角色作为字符串返回。

我希望您的ajax类似：

$.ajax({
    url: AppConfig.PrefixURL + "Home/ValidateUser",
    dataType: 'json',
    type: 'post',
    contentType: 'application/json',
    data: JSON.stringify(Values),
    processData: false,
    success: function (result) {
        //Here we will be returning the role as a string from the first ajax call and using it to check against in here

        //I just want you to essentiatly do the if statements in the controller here such as this

        if(result == "NEIQC_SAP_ENGINEER")
        {
            window.location.href = '@url.Action("Assign", "App")'
        }
    },
    error: function () {

    }
});

编辑：这个答案似乎与@TetsuyaYamamoto的非常相似。两者都应该起作用，但是是否使用switch语句的偏好完全取决于您
