Laravel Flash 消息在特定重定向路由的特定方法中不起作用

Question

我有一个很奇怪的问题。我的 Flash 消息在我创建 post 时不起作用，但在我删除或更新它时起作用，当我更改重定向方向时它也起作用。

所以在 store() 方法中，当我将创建的 post 保存到数据库时，我然后重定向到 /posts，如果我将它从 /posts 到 /anyotherroute 有效。

我的 update() 与 store() 相同，它也重定向到 /posts，但在更新时会出现 flash 消息，与 destroy() 相同。

有人知道这是为什么吗？

所以我刚刚注意到在本地主机上出现了闪现消息，但在共享主机上却没有。

商店()

public function store(Request $request){
$this->validate($request, [
  'title' => 'required',
  'body' => 'required',
  'cover_image' => 'image|nullable|max:1999'
]);

// Handle file upload

if($request->hasFile('cover_image')){
  // Get filename with the extension
  $fileNameWithExt = $request->file('cover_image')->getClientOriginalName();
  // Get just filename
  $fileName = pathinfo($fileNameWithExt, PATHINFO_FILENAME);
  // Get just ext
  $extension = $request->file('cover_image')->getClientOriginalExtension();
  // Filename to store 
  $fileNameToStore = $fileName . '_' . time() . '.' . $extension;
  // Upload Image 
  // $path = $request->file('cover_image')->storeAs('public/cover_images', $fileNameToStore);


  $file = $request->file('cover_image');
  Storage::disk('uploads')->put('posts_images/' . $fileNameToStore, File::get($file));
}else{
  $fileNameToStore = 'noimage.jpg';
}

// create post

$post = new Post;
$post->title = $request->input('title');
$post->body = $request->input('body');
$post->user_id = auth()->user()->id;
$post->cover_image = $fileNameToStore;
$post->save();

return redirect('/posts')->with('success', 'Post Created');

更新()

public function update(Request $request, $id){
$this->validate($request, [
  'title' => 'required',
  'body' => 'required',
  'cover_image' => 'image|nullable|max:1999'
]);

// Handle file upload

if($request->hasFile('cover_image')){
  // Get filename with the extension
  $fileNameWithExt = $request->file('cover_image')->getClientOriginalName();
  // Get just filename
  $fileName = pathinfo($fileNameWithExt, PATHINFO_FILENAME);
  // Get just ext
  $extension = $request->file('cover_image')->getClientOriginalExtension();
  // Filename to store 
  $fileNameToStore = $fileName . '_' . time() . '.' . $extension;
  // Upload Image 
  // $path = $request->file('cover_image')->storeAs('public/cover_images', $fileNameToStore);

  $file = $request->file('cover_image');
  Storage::disk('uploads')->put('posts_images/' . $fileNameToStore, File::get($file));
}

// create post
$post = Post::find($id);
$post->title = $request->input('title');
$post->body = $request->input('body');
if($request->hasFile('cover_image')){
  $post->cover_image = $fileNameToStore;
}
$post->save();

return redirect('/posts')->with('success', 'Post Updated');

消息()

    @if(count($errors) > 0)
  @foreach($errors->all() as $error)
    <div class="alert alert-danger">
      {{$error}}
    </div>

Answer 1

因此，由于某种原因，当我登录我的 google 帐户时，它没有出现在 Chrome 中。我去了我的笔记本电脑，在那里也使用了 Chrome，在笔记本电脑上它工作正常，然后我在我的电脑上更改了 google 帐户，它也工作正常。仅当我使用我的 google 帐户时它才不工作，即使我清除了历史记录、缓存和 cookie，但我想我不介意它是否对其他人有用。不管怎样，这真是个愚蠢的问题，很抱歉无缘无故地打扰你:(
