Laravel PATCH 适用于更新，但控制器中的验证失败

Question

我正在关注 Laracast 实验室、Tweety 提要，一切都很顺利，直到我碰壁。

我有一个补丁来更新用户配置文件，它可以工作并更新记录，但验证没有。如果完全完成并且记录很好，则表单提交，但如果表单验证在我的控制器中的服务器端失败，我得到如下：

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException 此路由不支持 GET 方法。支持的方法：POST。

我查看了此处的常见问题解答部分并搜索了已经询问过的网络并尝试了几个步骤来对此进行排序。我试过了：

1. 在我的编辑文件模板和控制器中使用 $user->username。

2. 将路径从 PATCH 更改为 PUT（以及 POST，只需使用 store）

3. 检查用户模型并确保我使用的“getRouteKeyName”工作正常，确实如此。
4. 检查路线是否有冲突，没有，顺序/动词没问题。

有人可以帮忙吗？下面是我的代码。

路线如下：

// Snippet for seeing all the database queries. 
//DB::listen(function($query){var_dump($query->sql, $query->bindings);});

use Illuminate\Support\Facades\Route;

 // Home view, no sign-in required. 
Route::get('/', function () {
return view('welcome');
});

// These routes require and use auth middleware.   
Route::middleware('auth')->group(function(){

// TWeets main page.
Route::get('/tweets/', 'TweetsController@index')->name('home');
// Store a new tweet
Route::post('/tweets/', 'TweetsController@store');

// Profile area, view and update

// Use the 'name' attribute in route/model binding instead of the primary key = user:name 
Route::get('/profile/{user:username}/', 'ProfileController@show')->name('profile');

// Show form to edit the profile
Route::post('/profile/{user:username}/edit','ProfileController@edit')->name('edit_profile');
//->middleware('can:edit,user'); // Don't forget the wildcard.

// Finally, update the users profile information.   
Route::patch('/profile/{user:username}','ProfileController@update')->name('update_profile');

// Handles the follow/unfollow on a toggle method.
Route::post('/profile/{user:username}/follow/','FollowsController@store');

// Logs you out & directs to the homepage.
Route::get('/logout', '\App\Http\Controllers\Auth\LoginController@logout');

});

Auth::routes();

控制器如下：

 /**
 * Update the users profile after validation
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function update(User $user)
{
        $validated = request()->validate([
            'name'=>'required',
            'username'=>'required',
            'password'=>'required',
            'password_confirmation'=>'required',
        ]);

         $user->update($validated);

    // Redirect to the tweets page which is called 'home'.
    return redirect(route('profile', $user->username));
}

模板：

<x-app>

<form class="w-full" method="POST" action="{{route('update_profile',$user)}}">

    @method('PATCH')
    @csrf

模型：用户

 /**
 * Laravel <=6 - use this method, after v6, you can do this on the route itself. 
 * Using this so we can use a user name in the route, instead of the ID Laravel normally uses for route/model binding. Now you can use /profile/mikethornley 
 * This will still enable route/model binding to work and still find the user
 * @return [type] [description]
 */
public function getRouteKeyName()
{
    return 'username';
}

Answer 1

这就是问题所在：

// Use the 'name' attribute in route/model binding instead of the primary key = user:name 
Route::get('/profile/{user:username}/', 'ProfileController@show')->name('profile');

// Finally, update the users profile information.   
Route::patch('/profile/{user:username}','ProfileController@update')->name('update_profile');

您的路线发生冲突...该帖子最终出现在 show() 方法中，这就是您收到错误的原因。

如果您想拥有参数，则需要对该发布路线进行一些更改。例如

Route::patch('/profile-update/{user:username}','ProfileController@update')->name('update_profile');
