Question

JSON：

laravel相当新，我的应用程序工作得很好，除了一件事，

当我去创建一个新帖子时，它无法保存到数据库并返回请求JSON页面。

非常感谢任何解决此问题的帮助！

我认为这个问题可能与雄辩有关，我所拥有的代码似乎无法找到错误。

创建帖子的控制器功能就是这个，

    public function create()
{
    $categories = Category::all();
    $tags = Tag::all();
    return view('posts.create')->withCategories($categories)->withTags($tags);
}

/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function store(Request $request)
{
    dd($request);
    // validate the data
    $this->validate($request, array(
            'title'         => 'required|max:255',
            'slug'          => 'required|alpha_dash|min:5|max:255|unique:posts,slug',
            'category_id'   => 'required|integer',
            'body'          => 'required'
        ));

    // store in the database
    $post = new Post;

    $post->title = $request->title;
    $post->slug = $request->slug;
    $post->category_id = $request->category_id;
    $post->body = Purifier::clean($request->body);

    $post->save();

    $post->tags()->sync($request->tags, false);

    Session::flash('success', 'The blog post was successfully save!');

    return redirect()->route('posts.show', $post->id);
}

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */

Answer 1

您的store()方法正在做的第一件事是：dd($request)。

dd()代表“dump and die”，它会转储传递给它的任何内容，然后调用die()。您看到的输出是$request变量的转储，然后脚本就会死掉。

Answer 2

如上所述，dd（$ request）返回请求的JSON值，您应该首次使用它来查看表单中是否传递了所有值，然后您应该省略它，将其用于测试目的仅
