Require authorization on ALL Blazor pages


I am playing with Blazor and created a web app that is server hosted. I have to put an authorize line on top of the page like this @attribute [Authorize] to ensure the user is logged in.

It seems like I have to add this line to each page individually. Is there a global setting that protects ALL the pages in the app, except for the login page of course.


Solution

  • I believe that will work... Place the following code snippet in the _Imports.razor file

    @using Microsoft.AspNetCore.Authorization
    @attribute [Authorize]
    

    In that case, when the Index page is hit, the user will be redirected to the Login page. If you want to perform authentication before the Blazor App is being render, add the code snippet from above in the _Host.cshtml file

    Add the @attribute [AllowAnonymous] to specific pages you want to exculde from authentication, as for instance, the Index page.
