Blazor authorization #9474

carl.hallqvist created one month ago

exceptionWe have problem to get https://abp.io/docs/latest/framework/ui/blazor/authorization to work in our Blazor project. This is what we have:

@page "/"
@using Microsoft.AspNetCore.Authorization
@attribute [Authorize("CustomerService.Customers")]
@inherits MyProjectComponentBase

@* https://abp.io/docs/latest/framework/ui/blazor/authorization *@
#AuthorizeView Policy="CustomerService.Customers.Create">
    <p>You can only see this if you satisfy the "CustomerService.Customers.Create" policy.</p>
#/AuthorizeView>

The #  is instead of < since CB does render it? A bug in the Write component maybe?

This is the MyProject_Administration database, AbpPermissions table:

And this is the exception in the browser:

The error The AuthorizationPolicy named: 'CustomerService.Customers' was not found. indicates that you are using ASP.NET Core's policy-based authorization, but you have not registered a policy named CustomerService.Customers in your application's authorization configuration.
In ABP Blazor applications, permissions are typically checked using the ABP permission system, not by defining custom ASP.NET Core authorization policies for each permission. The correct way to check for a permission in a Blazor component is to use the @attribute [Authorize] without a policy name, or to use the AbpAuthorizeView component for permission checks.
To check for a specific permission, use the ABP permission name in the AbpAuthorizeView component, like this:

@page "/"
@using Volo.Abp.AspNetCore.Components.Authorization

@attribute [Authorize] <!-- This just requires authentication -->

<AbpAuthorizeView Permission="CustomerService.Customers.Create">
    <p>You can only see this if you have the 'CustomerService.Customers.Create' permission.</p>
</AbpAuthorizeView>

If you want to use the standard AuthorizeView, you must define the policy in your Startup.cs or Program.cs:

services.AddAuthorization(options =>
{
    options.AddPolicy("CustomerService.Customers", policy =>
        policy.RequireClaim("Permission", "CustomerService.Customers"));
});

But this is not the recommended ABP way.

Make sure you are using the correct ABP permission system and components for permission checks in Blazor.
