localhost页面无效.localhost重定向了你太多次了

Question

调试我的MVC程序时遇到问题,我想访问名为"UserActivity"的数据库.在浏览器上,它说"localhost页面不起作用

localhost重定向了你太多次了."

但没有显示具体的错误位置.

这是我的UserActivtyController,GET/UserActivity/Index代码:

public class UserActivityController : BaseController
{
    //GET /UserActivity/Index
    public ActionResult Index(string returnUrl, int page = 1, string sort = "Id", string sortDir = "ASC", string filter = null)
    {
        String query = @"
            SELECT Id
            ,CreatedBy
            ,CreatedOn
            ,ModifiedBy
            ,ModifiedOn
            ,ContactId
            ,EntityName
            ,EntityId
            ,ActivityType
            ,ActivityStatus
            ,DueDate
            ,ActualEndDate
            ,MasqueradeOn
            ,MasqueradeBy 
        FROM UserActivity 
        -- ORDER BY CreatedOn DESC
        -- OFFSET (@PageNumber -1) * 30 ROWS
        -- FETCH NEXT 30 ROWS ONLY
            ";

        //string countQuery = @""

        List<UserActivityModels> userActivity = null;

        using (IDbConnection db = new MySqlConnection(ConfigurationManager.ConnectionStrings["CRMPORTALSQLCONN"].ConnectionString))
        {
            userActivity = (List<UserActivityModels>)db.Query<UserActivityModels>(query, new
            {
                @PageNumber = page,

            });

            /*ViewData["TotalCount"] = (int)db.ExecuteScalar(countQuery, new
            {
                @PageNumber = page,
                @Id = string.IsNullOrEmpty(filter) ? null : filter
            });
            */

            ViewData["PageSize"] = 30;
            ViewData["Filter"] = filter;
        }

        if (userActivity != null)
        {
            return RedirectToAction(returnUrl);
        }

        return View(userActivity);
    }
}

如果有人知道这个问题,真的很感激.谢谢

if (userActivity != null)
{
    return RedirectToAction(returnUrl);
}

如果returnUrl指向相同的操作（“ UserActivity / Index”），它将创建无限重定向循环。如果要将请求重定向到其他操作，请确保传递正确的名称。
