Question

我正在使用 Laravel 8 制作简单的甘特图，但遇到了问题。当我进行路由时，打开页面时出现404错误。顺便说一下，我正在使用 xampp。另外我是Laravel初学者，参考了某个页面的教程。 https://docs.dhtmlx.com/gantt/desktop__howtostart_php_laravel.html

[查看] gantt.blade.php

    gantt.init("gantt_here");
  
    gantt.load("/api/data");
</script>
</body>

[控制器] GanttController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Task;
use App\Models\Link;

class GanttController extends Controller
{
    public function get(){
        $tasks = new Task();
        $links = new Link();
 
        return response()->json([
            "data" => $tasks->all(),
            "links" => $links->all()
        ]);
    }
}

[路线] api.php

<?php

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
| Here is where you can register API routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| is assigned the "api" middleware group. Enjoy building your API!
|
*/

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

Route::get('/data', 'GanttController@get');

我自己无法解决，但我想这是因为路由。有人可以帮我吗？

确保你的 xampp 的 apache 和 mysql 服务正在运行，并且建议以新的方式而不是旧的方式定义你的路由，因此，首先启动您的 xampp 服务并进行更改：

Route::get('/data', 'GanttController@get');

进入

Route::get('/data', [GanttController::class, 'get']);

这是 laravel 8.x 中的新功能，然后查看您的代码，您正在创建 Task 和 Link 的新实例，并尝试从中获取数据，这是错误的方法.

你应该得到这样的数据：

$tasks = Task::all();
$links = Link::all();

当我使用 api.php 时，Laravel8 找不到 404 错误
