Laravel 為什么我的圖片發布功能無法正常工作？

Question

基本信息

我正在使用 Laravel6.0 開發一個簡單的 Web 應用程序。
我做了一個圖片發布功能，但它不能正常工作。
沒有錯誤消息。

問題

我無法發布圖像。
沒有改變。
它只是過渡到同一頁面。
create2.blade.php是發布圖像的形式，我想在index2.blade.php上查看此圖像

代碼

對不起我糟糕的英語，但是，我需要幫助。
等待您的評論和答復！

Answer 1

您的路由文件中有兩個POST /stories/create定義。

   Route::post('/stories/create', 'StoriesController@upload');
   ...
   Route::post('/stories/create', 'StoriesController@add');

處理的最后一個將接收對此路由的請求。 您應該能夠通過運行php artisan route:list並查看哪些路由可用以及它們映射到哪些控制器來在命令行上驗證這一點。 在這種情況下，您可能會點擊添加方法而不是上傳方法。

作為立即修復，從路由文件中刪除第二個定義，重新運行php artisan route:list以查找更改，並查看網頁的行為是否有所不同。

看起來您將面臨類似的問題：

  Route::post('/profile/create', 'ProfileController@add');
  Route::post('/profile/create', 'ProfileController@store');
  Route::post('/profile/create', 'ProfileController@upload');

足智多謀的路由可以幫助標准化路由，並避免很多像這樣的頭痛和困惑。 https://laravel.com/docs/6.x/controllers#resource-controllers

特別是，如果您按照https://laravel.com/docs/6.x/controllers#restful-partial-resource-routes 中的描述定義路由，則可以使用php artisan route:list來驗證每個路由是哪些方法映射到，然后更新您的控制器以匹配。

Route::resource('stories', 'StoriesController')->only([
    'index', 
    'create', 
    'store',
]);
