我使用本教程安装了Laravel UI https://www.itsolutionstuff.com/post/laravel-9-authentication-using-breeze-tutorialexample.html
登录和注册表单都在http://localhost:8000/login中，但是登录后，如果我进入中间件内部的路由（http://localhost:8000/api/categories），我会被重定向到主页。如果我有中间件外部的路由，它可以工作，但不需要登录。

工作（至少在“类别”视图中显示）

Route::controller(App\Http\Controllers\API\CategoryController::class)->group(function(){
        Route::get('categories', 'index')->name('categories.index')
    });

不工作（重定向到主视图）

Route::group(['middleware' => 'auth:api'], function(){
    Route::controller(App\Http\Controllers\API\CategoryController::class)->group(function(){
        Route::get('categories', 'index')->name('categories.index')
    });
});

类别控制器

<?php

        return response()->json($cat);
    }

    /**

     *
     * @return \Illuminate\Http\Response

    public function create()

        $cat = $this->getCategories();
        return view('create-category',compact('cat'));
    }

            $cat = $cat->where('id', $category_id)->get()->keyBy('id');
        } else {
            $cat = $cat->whereNull('parent_id')->get()->keyBy('id');

            foreach($cat as $catID=>$catArray) {
                $subCat = $this->getChildCategory($catID, 'id');

                if ($subCat->first()) {
                    $cat[$catID]['subcat'] = $subCat;
                }
            }
        }
        return $cat;
    }

    public function createCategoryForm() {

    public function categoryDropown($child_id = null) {
        $cat = $this->getCategories();
    }

我已经使用Laravel有一段时间了，但这是第一次用Auth从头开始创建应用程序。我不知道我错过了什么。TIA
