Jadi saya cuba bermain dengan bahagian hadapan dan belakang sedikit. Apabila cuba menghantar data dari bahagian hadapan ke pelayan saya mendapat

Akses kepada XMLHttpRequest di 'http://test.localhost/login' dari asal 'http://localhost:3000' telah disekat oleh dasar CORS: Respons kepada permintaan pra-penerbangan gagal Semakan Kawalan Akses: Tiada 'Kawalan-Akses' - Pengepala Allow-Origin' terdapat pada sumber yang diminta

Berikut ialah tetapan axios saya onClick:

export const login = (email, password) => {
  return axiosClient.post('/login', { email, password })
    .then(response => {
      // handle successful login
      return response.data;
    })
    .catch(error => {
      // handle failed login
      throw error;
    });
};

AxiosClient saya ialah:

import axios from "axios";
const axiosClient = axios.create({
  baseURL: process.env.REACT_APP_API_URL, (my localhost)
  headers: {
    'Content-Type': 'application/json',
    Accept: 'application/json',
  },
});
export default axiosClient;

Konfigurasi cors saya di bahagian belakang ialah

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class Cors
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure(\Illuminate\Http\Request): (\Illuminate\Http\Response|\Illuminate\Http\RedirectResponse)  $next
     * @return \Illuminate\Http\Response|\Illuminate\Http\RedirectResponse
     */
    public function handle($request, Closure $next)
    {
        $headers = [
            'Access-Control-Allow-Origin' => 'http://localhost:3000',
            'Access-Control-Allow-Methods' => 'GET, POST, PUT, DELETE, OPTIONS',
            'Access-Control-Allow-Headers' => 'Content-Type, Authorization',
        ];

        if ($request->isMethod('OPTIONS')) {
            return response()->json([], 200, $headers);
        }

        $response = $next($request);

        foreach ($headers as $key => $value) {
            $response->header($key, $value);
        }

        return $response;
    }
}
