codeigniter 4 - 找不到控制器或其方法

Question

当我在本地服务器上测试时运行很好，但是当我将 000webhost 服务器上传到它时显示错误。

an error 我的路线：

我的路线：

$routes->get('/komik/create', 'komik::create');
$routes->get('/komik/edit/(:segment)', 'komik::edit/');
$routes->delete('/komik/(:num)', 'komik::delete/');
$routes->get('/komik/(:any)', 'Komik::detail/');

谁能帮帮我？

我的控制器

一个错误

Controller or its method is not found: \App\Controllers\komik::create

我试图在url中隐藏细节的方法，运行在本地服务器上没问题但是为什么当我上传到虚拟主机时显示错误

Answer 1

你好，我刚刚看了你的代码，我认为 codeigniter 4 在检测路由方面更强大。根据您的路线，您甚至不需要创建这些路线。在不创建路由的情况下调用您的控制器和方法。

就是这里


namespace App\Controllers;

use App\Models\Data_KomikModel;
use App\Models\GambarModel;
use App\Models\SoalModel;

class Komik extends BaseController
{
    protected $komikModel;
    public function __construct()
    {
        $this->komikModel = new Data_KomikModel();
        $this->gambarModel = new GambarModel();
        $this->soalModel = new SoalModel();
        // dd(session()->get('email'));

    }
    public function index()
    {
        if (!session()->has('username')) {
            return redirect()->to('/auth/login');
        }
        // $komik = $this->komikModel->findAll();
        $data = [
            'title' => 'Data Komik',
            'komik' => $this->komikModel->getKomik()
        ];
        // $komikModel = new \App\Models\Data_KomikModel();
        // $komikModel = new Data_KomikModel();

        return view('dataKomik/komik', $data);
    }

    public function detail($slug)
    {
        $komik = $this->komikModel->getKomik($slug);
        $gambar = $this->gambarModel->getGambar($slug);
        $soal = $this->soalModel->getDataSoal($slug);
        // dd($soal);
        $data = [
            'title' => 'Info Komik',

            return redirect()->to('/komik/create')->withInput();
        }

            return redirect()->to('/komik/edit/' . $this->request->getVar('slug'))->withInput();

        $fileSampul = $this->request->getFile('sampul');
        $komik = $this->komikModel->find($id);
        if ($fileSampul->getError() == 4) {
            $namaSampul = $this->request->getVar('sampulLama');
        } else {
            $namaSampul = $fileSampul->getRandomName();
            $fileSampul->move('img', $namaSampul);
            if ($komik['sampul'] != 'default.jpg') {

        </button>
      </div>');
        return redirect()->to('/komik');
    }
    //--------------------------------------------------------------------

}

然后在你的链接中使用这个

<a href="<?= base_url('komik/create')?>"> Create</a>

或

如果还需要使用路由，去掉路由前面的正斜杠代替


$routes->get('/komik/create', 'komik::create');
$routes->get('/komik/edit/(:segment)', 'komik::edit/');
$routes->delete('/komik/(:num)', 'komik::delete/');
$routes->get('/komik/(:any)', 'Komik::detail/');

使用这个

$routes->get('komik/create', 'komik::create');
$routes->get('komik/edit/(:segment)', 'komik::edit/');
$routes->delete('komik/(:num)', 'komik::delete/');
$routes->get('komik/(:any)', 'Komik::detail/');

我认为这有帮助！如果不引起我的注意

Answer 2

注意区分大小写，改成：

$routes->get('/komik/create', 'komik::create');

至：

$routes->get('/komik/create', 'Komik::create');
