我正在跟Laracast实验室，Tweety提要一起跟踪，直到我撞墙之前一切都很好。
我有一个PATCH可以更新用户个人资料，它可以工作并更新记录，但是验证没有。如果完全完成并且记录很好，则提交表单，但是如果表单验证在我的控制器的服务器端失败，我将得到以下信息：
Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException该路由不支持GET方法。支持的方法：POST。
我看过这里的FAQ部分，并搜索了已经问过的网络，并尝试了几个步骤来对此进行排序。我尝试过：
在编辑文件模板和控制器中使用$ user->用户名。
更改从PATCH到PUT的路线（还有POST，只需使用存储即可）
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：

Model：User
/**

*/
public function getRouteKeyName()
{
return 'username';
}
这是问题：
// 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。
如果您想要参数，则需要对该发布路线进行一些更改。例如
Route::patch('/profile-create/{user:username}','ProfileController@update')->name('update_profile');
