我的控制器功能

<?php

namespace App\Http\Controllers;

use App\News;
use Illuminate\Http\Request;

class NewsController extends Controller
{

    public function index()
    {
        $news=News::all();
        return view('news.index',['news'=>$news]);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
//        return view('news.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  \App\News  $news
     * @return \Illuminate\Http\Response

    public function show(News $news)
    {

    public function edit(News $news)
    {
        //

    /**

Answer 1

您有重叠的路线定义：

Route::get('/news','NewsController@index');
Route::get('/news','NewsController@create');

正在使用后者。

可能会将后者改为：

Route::get('/news/create', 'NewsController@create');

Answer 2

如果它没有显示任何内容，可能会关闭Laravel的错误报告功能。因为它几乎总是说出了什么错。也许你应该首先考虑一下。

Answer 3

您的路线出现问题。因为一旦您使用资源然后使用声明路线作为获取，首先您要清除您正在使用的路线。

以下是使用资源时的示例。

https://github.com/angular/material2/tree/master/src/material-examples/table-filtering

Answer 4

Remove这些行已经声明resource路由：

Route::get('/news','NewsController@index');
Route::get('/news','NewsController@create');

Answer 5

您的路线被第二条路线取代，这就是为什么它显示空白页面，因为您的create（）不会做任何事情，即空页。

我建议你重命名创建路线，如下所示请尝试以下代码：

Route::get('/news','NewsController@index');
Route::get('/news/create','NewsController@create');

Answer 6

尝试删除存储在storage -> framework -> cache folder

中的缓存

如果仍然失败，请尝试通过您的cmd致电composer dump-autoload重新加载您的源代码。

Laravel视图没有显示任何显示空白的内容
