    }

    // 创建新文章
    public function create()
    {

    // 保存新文章
    public function store(Request $request)
    {
        $article = Article::create($request->all());

        return redirect('/articles');
    }

    // 编辑文章
    public function edit(Article $article)
    {
        return view('articles.edit', ['article' => $article]);
    }

    // 更新文章
    public function update(Request $request, Article $article)
    {
        $article->update($request->all());

        return redirect('/articles/' . $article->id);
    }

    // 删除文章
    public function destroy(Article $article)
    {
        $article->delete();

        return redirect('/articles');
    }
}

2. Create a view

Create the following view file:

• resources/views/articles/index.blade.php
• resources/views/articles/show.blade.php
• resources/views/articles/create.blade.php
• ##resources/views/articles/edit.blade.php

3. Browse your application

Navigate to

http://localhost:8000/articles to view your CRUD application.
