getAllPermissions 这个方法是调用哪里的？

spatie/laravel-permission 扩展包里面

更明确的说，在vendor/spatie/laravel-permission/src/Traits/HasPermissions.php中。

    /**
     * Return all the permissions the model has, both directly and via roles.
     */
    public function getAllPermissions(): Collection
    {
        $permissions = $this->permissions;

        if ($this->roles) {
            $permissions = $permissions->merge($this->getPermissionsViaRoles());
        }

        return $permissions->sort()->values();
    }
