Laravel 上的“Action App\Http\Controllers\CommentRepliesController@createReply 未定义”错误

Question

我正在尝试在帖子中添加回复 cmets 的选项，但我不断收到：

CommentRepliesController@createReply 未定义。

通过PostCommentsController@store 添加对帖子的回复非常有效。但是，当我尝试通过返回帖子或直接转到 URL 中的comment/reply 来添加对评论的回复时，它给了我上面的错误。

以下是我的路线：

Route::group(['middleware'=>'auth'], function(){
    Route::resource('comment/reply', 'CommentRepliesController@createReply');
});

以下是我的CommentRepliesController@createReply：

public function createReply(Request $request){
    $user = Auth::user();
    if($user->photo){
        $data = [
        'comment_id' => $request->comment_id,
        'author' => $user->name,
        'email' => $user->email,
        'photo' => $user->photo->file,
        'body' => $request->body
    ];       
    } else{
        $data = [
        'comment_id' => $request->comment_id,
        'author' => $user->name,
        'email' => $user->email,
        'body' => $request->body
    ];
    }

    CommentReply::create($data);
    $request->session()->flash('reply_message', 'Your reply has been submitted 
                                 and is awaiting moderation.');
    return redirect()->back();

}

以下是我的 post.blade.php：

@extends('layouts.blog-post')

@section('content')

    <!-- Blog Post -->

    <!-- Title -->
    <h1>{{$post->title}}</h1>

    <!-- Author -->
    <p class="lead">

提前谢谢你。

Laravel 资源路由通过一行代码将典型的“CRUD”路由分配给控制器。

Route::resource 自动使用资源控制器中的“CRUD”操作。请参阅文档here

如果您想在控制器中使用特定功能，请不要使用Route::resource。使用任何你想要的方法。例如，如果您的方法是 POST，请像这样使用 Route::post：

Route::group(['middleware'=>'auth'], function(){
    Route::post('comment/reply', 'CommentRepliesController@createReply');
});
