Hello, when you start a web application on ASP.NET MVC, the default Default.aspx page loads, it does not display png pictures, and an error occurs

: 33120 / Views / Default? ReturnUrl =% 2fScripts% 2fjquery-3.1.0.js: 2 Uncaught SyntaxError: Unexpected token <

and in the address bar is displayed

localhost: 33120 / Views / Default? ReturnUrl =% 2fViews% 2fDefault.aspx

at the same time, the line number in the error apparently refers to this line in Default.aspx (since as you move this line, the number in the error changes accordingly.)

<!DOCTYPE html>

After searching for similar errors on the Internet, I found that the problem could be related to the use of System.Web.Routing. The application has a general structure.

  • Views
    • Default.aspx
  • Content
    • bootstrap.min.css
  • Resources
    • Images
      • logo.png
  • Scripts
    • jquery-3.1.0.js
  • Global.asax.cs

Therefore, in the RegisterRoutes method of the class Global.asax.cs added

 routes.RouteExistingFiles = false; routes.IgnoreRoute("{folder}/{*pathInfo}", new { folder = "Scripts" }); routes.IgnoreRoute("{folder}/{*pathInfo}", new { folder = "Content" }); routes.IgnoreRoute("{folder}/{*pathInfo}", new { folder = "Resources" });

When calling a picture in Default.aspx

 <img class="img-responsive center-block" src=" <% ResolveUrl("~/Resources/Images/logo.png");%>" alt="Image is lost."/>

But nothing has changed and did not help. Help solve this problem, please.

PS Contents default.aspx (without the first default line)

Part of the code from Default.aspx.cs

 protected void btnLogin_OnClick(object sender, EventArgs e) { CustomValidator_UserEmail.Validate(); CustomValidator_UserPass.Validate(); if (!Page.IsValid) { return; } var login = ClientServiceFactoryClass.CompanyService.AuthenticateUser(UserEmail.Text, UserPass.Text); if (login != -1) { FormsAuthentication.RedirectFromLoginPage(UserEmail.Text, cbRememberPassword.Checked); Response.Redirect(login == 1 ? Routes.HOME_PAGE_OF_ADMIN : Routes.PAGE_OF_COMPANY_SHORT); } else { lblMessageIncredential.Text = Dictionary.INVALID_LOGIN; UserEmail.Text = string.Empty; UserPass.Text = string.Empty; } }

Where, for example, public const string HOME_PAGE_OF_ADMIN =@"HomeAdmin.aspx";

Content of the RegisterRoutes method

 routes.RouteExistingFiles = false; routes.IgnoreRoute("{folder}/{*pathInfo}", new { folder = "Scripts" }); routes.IgnoreRoute("{folder}/{*pathInfo}", new { folder = "Content" }); routes.IgnoreRoute("{folder}/{*pathInfo}", new { folder = "Resources" }); routes.EnableFriendlyUrls();

When prompted, localhost: 33120 / displays in the address bar localhost:33120/Views/Default?ReturnUrl=%‌​2f for localhost: 33120 / Default this address remains, but errors still occur.

Remove the runAllManagedModulesForAllRequests attribute

 <modules runAllManagedModulesForAllRequests="true"> <remove name="UrlRoutingModule" /> </modules>

It pushes all requests in asp.net, including requests to static files - and authorization rules begin to apply to them.

And better - remove this section entirely. Most likely you for some reason entered <remove name="UrlRoutingModule" /> , extensionless urls stopped working for you, and you googled a crutch in the form of runAllManagedModulesForAllRequests = "true".

Remove both crutches - and it will work.

And yes, since this is an ASP.NET MVC application - your links should lead to controller methods, for example /Default . For some reason, you have a view - Views/Default as your login page. Your page is at least somehow displayed only because you have removed the protection against direct access to Views / Web.config.

If we take into account that at the same time, that you are using server-side controls on the presentation ( runat="server" , btnLogin_OnClick ) - you have an ordinary Web Pages (not MVC) application in which you have for some reason routing and the pages are folded in Views folder. Try creating an ASP.NET MVC application and see where action handlers fit in it and where is the result display.

  • Thank you very much! Your decision helped, everything was displayed. PS true url remained localhost:33120/Views/Default?ReturnUrl=%2fViews%2fDefault.aspx , but I understood that you need to take into account your second part of the message and redo it? - onlNas
