Question

我是Laravel的初学者，所以我不确定我这样做是否正确，但一整天都在苦苦挣扎。以下是我的代码：

控制器：

<?php namespace virtualine\Http\Controllers;

use View;
use Form;
use Response;

use virtualine\Post;
use virtualine\Comment;


use virtualine\Http\Requests;
use virtualine\Http\Controllers\Controller;

use Illuminate\Http\Request;

class PostController extends Controller {

    public function index()
    {
        // $post = Post::orderBy('created_at', 'desc')->first();

        $post = Post::get();
        return Response::json($post);

        //return View::make('posts.index')
        //  ->with('posts', $posts);
    }

    public function create()
    {
        // return View::make('posts.create');
    }

    public function store()
    {
        Post::create(array(
            'question' => Input::get('question')
        ));

        return Response::json(array('success' => true));
    }

    public function show($id)
    {
        $post = Post::find($id);
        $comments = Comment::GetComments($id)->get();

        return Response::json(['question' => $post->question, "comments" => $comments]);
    }

    public function edit($id)
    {
        $post = Post::find($id);

        return Response::json($post);
    }

    public function update($id)
    {
        //
    }

    public function destroy($id)
    {
        Post::destroy($id);

        return Response::json(array('success' => true));
    }

}

路线：

Route::get('/', 'WelcomeController@index');

Route::get('home', 'HomeController@index');

Route::group(array('prefix' => 'api'), function() {
    Route::resource('posts', 'PostController',
    array('except' => array('index', 'store', 'destroy'))));
});

Route::controllers([
    'auth' => 'Auth\AuthController',
    'password' => 'Auth\PasswordController',
]);

我正在尝试使用上述路线来存储和删除记录。我能够查看它们但不能存储或删除任何内容。对于api / posts / 1 / destroy（GET），我得到：

TokenMismatchException in VerifyCsrfToken.php line 46:

at require_once('/Library/WebServer/Documents/virtualine/virtualine/public/index.php') in server.php line 21

对于api / posts / store我得到：

非常感谢任何帮助。

您必须使用表单数据发送csrf令牌，例如，如果您有一个名为add_question.blade.php的刀片文件，则包含以下格式：

 <form action="{{action('PostController@index')}}" method="post" ><input type="text" name="question" ><input type="submit"></form>

只需添加以下字段：

<input type="hidden" name="_token" value="{{ csrf_token() }}" />

所以看起来应该是这样的：

     <form  action="{{action('PostController@index')}}" method="post" ><input type="hidden" name="_token" value="{{ csrf_token() }}" /><input type="text" name="question" ><input type="submit"></form>

我试图在Laravel中创建一个基本API，但无法通过它保存或删除任何数据
