codeigniter 4 - 找不到控制器或其方法

Question

当我在本地服务器中测试时它运行良好，但是当我上传 000webhost 服务器时它显示错误。

错误 我的路线：

我的路线：

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

$routes->get('/komik/edit/(:segment)', 'komik::edit/$1');

$routes->delete('/komik/(:num)', 'komik::delete/$1');

$routes->get('/komik/(:any)', 'Komik::detail/$1');

有人可以帮助我吗？

一个错误

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

我尝试在 url 中隐藏详细信息的方法，它在本地服务器中运行良好，但为什么当我上传到网络托管时它显示错误

你好，我只是看看你的代码，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。调用您的控制器和方法而不创建路由。就这个namespace App\Controllers;use App\Models\Data_KomikModel;use App\Models\GambarModel;use App\Models\SoalModel;class Komik extends BaseController{&nbsp; &nbsp; protected $komikModel;&nbsp; &nbsp; public function __construct()&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; $this->komikModel = new Data_KomikModel();&nbsp; &nbsp; &nbsp; &nbsp; $this->gambarModel = new GambarModel();&nbsp; &nbsp; &nbsp; &nbsp; $this->soalModel = new SoalModel();&nbsp; &nbsp; &nbsp; &nbsp; // dd(session()->get('email'));&nbsp; &nbsp; }&nbsp; &nbsp; public function index()&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; if (!session()->has('username')) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return redirect()->to('/auth/login');&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; // $komik = $this->komikModel->findAll();&nbsp; &nbsp; &nbsp; &nbsp; $data = [&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'title' => 'Data Komik',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'komik' => $this->komikModel->getKomik()&nbsp; &nbsp; &nbsp; &nbsp; ];&nbsp; &nbsp; &nbsp; &nbsp; // $komikModel = new \App\Models\Data_KomikModel();&nbsp; &nbsp; &nbsp; &nbsp; // $komikModel = new Data_KomikModel();&nbsp; &nbsp; &nbsp; &nbsp; return view('dataKomik/komik', $data);&nbsp; &nbsp; }&nbsp; &nbsp; public function detail($slug)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; $komik = $this->komikModel->getKomik($slug);&nbsp; &nbsp; &nbsp; &nbsp; $gambar = $this->gambarModel->getGambar($slug);&nbsp; &nbsp; &nbsp; &nbsp; $soal = $this->soalModel->getDataSoal($slug);&nbsp; &nbsp; &nbsp; &nbsp; // dd($soal);&nbsp; &nbsp; &nbsp; &nbsp; $data = [&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'title' => 'Info Komik',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'komik' => $komik,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'gambar' => $gambar,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'soal' => $soal,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'validation' => \Config\Services::validation()&nbsp; &nbsp; &nbsp; &nbsp; ];&nbsp; &nbsp; &nbsp; &nbsp; if (empty($data['komik'])) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; throw new \CodeIgniter\Exceptions\PageNotFoundException('Judul Komik ' . $slug .

Answer 2

注意区分大小写，更改：$routes->get('/komik/create',&nbsp;'komik::create');到 ：$routes->get('/komik/create',&nbsp;'Komik::create');
