Laravel中如何在同一/register URL下实现用户注册功能？

Hey there! No need to use resource controllers to make this work—we can set up separate HTTP method routes for the same /register URL, and tweak your controller and form to match. Let's break this down step by step:

1. Adjust Your Routes (web.php) #

Laravel lets you define routes for different HTTP methods on the same URL. We'll keep the GET route for showing the registration form, and add a POST route that points to your create() method to handle form submissions:

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

// Show register form (responds to GET requests)
Route::get('register', 'Authentication\RegisterController@index');
// Handle register form submission (responds to POST requests)
Route::post('register', 'Authentication\RegisterController@create');

Route::get('/login', function() {
    return view('auth.login');
})->name('login');

2. Fix Up the RegisterController #

Your current controller has a couple of small issues we need to resolve to get validation and user creation working properly:

• A typo in the validation rules (lame instead of lname)
• Incorrect validation logic in the validator() method
• Missing user creation logic after validation

Here's the corrected controller:

<?php

namespace App\Http\Controllers\Authentication;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\User; // Import your User model

class RegisterController extends Controller
{
    public function index()
    {
        return view('auth.register');
    }

    // Returns validation rules as an array
    protected function validator()
    {
        return [
            'fname' => 'required|string|max:255',
            'lname' => 'required|string|max:255', // Fixed typo from 'lame'
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6',
        ];
    }

    protected function create(Request $request)
    {
        // Run validation using our predefined rules
        $validatedData = $request->validate($this->validator());

        // Create and save the new user to the database
        User::create([
            'fname' => $validatedData['fname'],
            'lname' => $validatedData['lname'],
            'email' => $validatedData['email'],
            'password' => bcrypt($validatedData['password']), // Always hash passwords!
        ]);

        // Redirect to login page with a success message (adjust to your dashboard if needed)
        return redirect()->route('login')->with('success', 'Registration successful!');
    }
}

3. Update the Form Action in register.blade.php #

Right now your form is pointing to /register/create, but we need it to submit to our new POST route at /register. Update the action attribute:

<form class="form-signin" method="post" accept-charset="utf8" action="/register">
    @csrf
    <!-- Rest of your form content remains the same -->
</form>

Quick Additional Tips #

• Make sure your User model has fname, lname, email, and password listed in its $fillable property to allow mass assignment
• The success message we added can be displayed in your login view using @if(session('success')) <div class="alert-success">{{ session('success') }}</div> @endif
• You can customize the redirect destination after registration to point to your app's dashboard instead of the login page
