单击更新帖子按钮后，出现MethodNotAllowedHttpException错误

标签： php laravel forms

我正在尝试使用Laravel Framework使用Laravel的集体形式来更新帖子。但是，单击更新按钮后，出现错误“ MethodNotAllovedHttpEkception没有消息”。另外，当我单击子显示按钮以更新帖子时，URL上会出现问号符号，例如：Localhost:8000/edit?5。有人知道这里出什么问题吗？

我没有使用Laravel Form Collective，但是在您的刀片中，我发现了几个错误：

  1. 由于要更新，因此必须添加PUT方法
  2. 您必须添加CSRF令牌

请参阅this documentation link。

您的路线也有错误。更新功能需要$id才能找到特定的帖子（$id）。

因此，如下更改该路线：

Route::post('/edit/{$id}', 'MainController@update')->name('post.update');

如果修复后仍存在相同问题，请告知：）
