我试图创建一个控制器，处理通过AJAX调用提交表单。
我试着按照拉威尔的文件，圣人文件没有工作。404（Not Found）页面没有找到
控制器

namespace App\Http\Controllers;

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

class NewsLetterSignupController extends Controller
{
    public function SignupToNewsletter(Request $request)
    {
        $validatedData = $request->validate([
            'firstName' => 'required|string|max:255',
            'lastName' => 'required|string|max:255',
            'email' => 'required|email',
        ]);
        return response()->json(['message' => 'Form submitted successfully']);
    }
}

路线

<?php
use Illuminate\Support\Facades\Route;

use App\Http\Controllers\NewsLetterSignupController;

Route::post('/signup', 'App\Http\Controllers\NewsLetterSignupController@SignupToNewsletter');
