Laravel 每当我尝试提交我创建的注册表单时，都会弹出错误“404 not found”

Question

我已经进入 laravel 几天了，我正在接受教程指导。我被引导创建一个注册和登录表格。问题是，每当我在填写注册表单后单击提交按钮时，都会收到“404，未找到”错误。我还在命令行上运行 "php artisan route:list" 并且我的注册路径列在那里。最糟糕的是我不知道错误来自哪里。

代码如下：

WEB.PHP
use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| 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 :: group (['middleware' => ['web']], function () {
   Route::get('/', function () {
    return view('welcome');
   });
   Route::post('/signup', [
        'uses' => 'UserController@postSignUp',
        'as' => 'signup'
   ]);
    
});
?>

伙计们，这是 UserController 文件

用户CONTROLLER.PHP

<?php
namespace App\Http\Controllers;

use App\user;
use Illuminate\Http\Request;

class UserController extends Controller {
    public function postSignUp(Request $request){
        $email = $request ['email'];
        $first_name = $request ['first_name'];
        $password = bcrypt($request ['password']);
        
        $user = new user();
        $user -> email = $email;
        $user -> first_name = first_name;
        $user -> password = $password;
        
        $user -> save();
        
        return redirect() -> back();
        
        
    }

    public function postSignIn (Request $request){
        
    
    }

}


?>

Answer 1

如果您尝试手动构建 url 并在浏览器中输入 /signup 会发生什么情况？如果你得到 404 尽管你在浏览器中硬输入 url 那么你在 web.php 中有问题另一个条目可能是

Answer 2

有几种情况可能会导致这种情况：

该路线不存在 - 不太可能，因为您已检查过 route:list
您重定向到的路由不存在 - 从 POST 请求到控制器的典型响应是 redirect() 到视图或路由。这可能是您的错误发生的地方。
您有两条或更多条路线对应 URL - 由于路线文件中路线从上到下的评估顺序，这可能是偶然发生的。

Answer 3

伙计们，我解决了。我使用命令提示符输入代码“php artisan serve --port= xxxx”，xxxx 是我连接 laravel 的新端口的编号，然后我能够在单击我创建的表单的注册按钮。我看到错误在哪里。所以我在 UserController.php 代码中忘记了一个美元符号。感谢你们的努力。
