如何在服务器上执行数据库操作。-使用Laravel 6.0？

<?php

namespace App\Http\Controllers;

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

class UserController extends Controller
{
    public function getUsers()
    {
        $users = DB::table('users')->get();

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

    public function getUser($id)
    {
        $user = DB::table('users')->where('id', $id)->first();

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

    public function createUser(Request $request)
    {
        $name = $request->input('name');
        $email = $request->input('email');

        $userId = DB::table('users')->insertGetId([
            'name' => $name,
            'email' => $email,
        ]);

        return response()->json(['id' => $userId]);
    }

    public function updateUser(Request $request, $id)
    {
        $name = $request->input('name');
        $email = $request->input('email');

        DB::table('users')->where('id', $id)->update([
            'name' => $name,
            'email' => $email,
        ]);

        return response()->json(['message' => 'User updated successfully']);
    }

    public function deleteUser($id)
    {
        DB::table('users')->where('id', $id)->delete();

        return response()->json(['message' => 'User deleted successfully']);
    }
}
