授权或者方法总是为laravel策略返回false

Question

I'm having trouble setting up policy in Laravel. I'm using Laravel voyager admin panel that comes integrated with Laravel policy concept. I have created policy for content model and assigned it to Content BREAD. Just to check the result, I simply returned true in view function. And yet, it still returns false.

Here is a snippet from ContentPolicy class:

    /*
     * Determine whether the user can view the content.
     *
     * @param  \App\User  $user
     * @param  \App\Content  $content
     * @return mixed
     */
    public function view(User $user, Content $content)
    {
        return true;
    }

and here in ContentController:

    public function view(Request $request)
    {
        $content=Content::all();

        return var_dump($this->authorize("view",$content));
    }

and here I registered my policy

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'App\Model' => 'App\Policies\ModelPolicy',
        Content::class => ContentPolicy::class

    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();
        Passport::routes();

        //
    }
}

It is worth to note that 'browse_admin' works fine in such case for laravel voyager.

I appreciate your help. Thanks in advance

Based on Laravel Documentation you should register your policies in AuthServiceProvider like this:

<?php

namespace App\Providers;

use App\Content;
use App\Policies\ContentPolicy;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        Content::class => ContentPolicy::class,
    ];

    /**
     * Register any application authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        //
    }
}
