php – Laravel动作未经授权

我正在尝试删除属于创建它的用户的帖子,但是我收到此错误(顺便说一下,这是在网络日志中)

“/Applications/MAMP/htdocs/eli42/vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.PHP”
line : 201 message : “This action is unauthorized.” trace : [{,…},…]

我正在使用laravel 5.5 policy,不确定我是否正确行事,我在我的AuthServiceProvider中注册了$protected policies

Post :: class => PostPolicy ::类,

路线

Route :: delete(‘auth / post / {id}’,’PostController @ destroy’);

PostPolicy.PHP

<?PHP

namespace App\Policies;

use App\User;
use App\Post;

use Illuminate\Auth\Access\HandlesAuthorization;

class PostPolicy
{
    use HandlesAuthorization;

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

    /**
     * Determine whether the user can create posts.
     *
     * @param  \App\User  $user
     * @return mixed
     */
    public function create(User $user)
    {
        //
    }

    /**
     * Determine whether the user can update the post.
     *
     * @param  \App\User  $user
     * @param  \App\Post  $post
     * @return mixed
     */
    public function update(User $user, Post $post)
    {
        //
    }

    /**
     * Determine whether the user can delete the post.
     *
     * @param  \App\User  $user
     * @param  \App\Post  $post
     * @return mixed
     */
    public function delete(User $user, Post $post)
    {
        //

        return $user->id === $post->user_id;

    }

PostController.PHP(此文件有更多代码,但我想突出显示删除功能)

<?PHP

namespace App\Http\Controllers;

use App\Post;
use App\User;
use App\Policies\TaskPolicy; 


use Illuminate\Http\Request;
use Illuminate\Http\Response;

class PostController extends Controller
{

    public function destroy($id, Post $post)
    {
        $mypost = $this->authorize('delete',$post);

        if($mypost){
             Post::destroy($id);

        }




    }
}

Main.js删除帖子

$scope.deletePost = function(post){
    var index = $scope.myposts.indexOf(post);

    if(index != -1){
        $scope.myposts.splice(index, 1);
    }

    $http.delete('auth/post/' + post.id);

};

HTML

   <button ng-click="deletePost(post)">x</button>

之前

后

解决方法:

你不需要检索帖子,让Laravel为你做这件事.

编辑您的路线如下：

Route :: delete(‘auth / post / {post}’,’PostController @ destroy’);

请注意,大括号之间的帖子将是Laravel找到的分配给帖子的变量名称.如果没有找到帖子,Laravel将返回Not Found 404.

然后在你的控制器中,你必须告诉Laravel你期望有一个帖子通过这条路线：

方法符号将是这样的：destroy(Post $post). $post是您路线中的{post}.

最后,对于授权,您将无法获得授权方法返回的帖子.您将Laravel找到的$post传递给authorize方法.

这是完整的方法：

public function destroy(Post $post)
{
    $this->authorize('delete', $post);

    if ($post->delete()) {
        return response()->json(['message' => 'deleted']);
    };

    return response()->json(['error' => 'something went wrong'], 400);
}
