javascript – 使用ajax在laravel上的VerifyCsrfToken.php第67行中的TokenMismatchException

该视图有一个调用javascript函数的链接

@extends('layouts.main')

@section('content')
    <table class="table">
        <tr>
            <th>ID</th>
            <th>Nombre</th>
            <th>Opción</th>
        </tr>
    @foreach ($tasks as $task)
        <tr>
          <td>{{$task->id}}</td>
            <td>{{$task->name}}</td>
            <td><a href="javascript:void(0)" onclick="eliminar({{$task->id}})" class="btn btn-danger">Eliminar</a></td>
        </tr>
    @endforeach
    </table>
@stop

这是javascript代码

function eliminar(id){
  $.ajax({

           type: "DELETE",
           url: "task/"+id,
           success: function (data) {
               console.log(data);
           },
           error: function (data) {
               alert('Error:', data);
           }
    });
}

并使用ajax调用我想调用我的控制器的destroy方法

<?PHP

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Task;

class TaskController extends Controller
{
    /**
     * display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $tasks = Task::all();
        return view('mainview',['tasks' => $tasks]);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function 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  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        return "destroy";
    }
}

但是,当我点击链接时,我收到此错误：

TokenMismatchException in VerifyCsrftoken.PHP line 67

我是Laravel的新手,但我认为csrf适用于表格.

解决方法:

您应该将csrf_field添加到主刀片：

{{ csrf_field() }}

然后将_token添加到您的请求中：

var _token = $('input[name="_token"]').val();

function eliminar(id){
  $.ajax({
    type: "DELETE",
    url: "task/"+id,
    data: { _token : _token },
    success: function (data) {
      console.log(data);
    },
    error: function (data) {
      alert('Error:', data);
    }
  });
}

或者您可以在ajaxSetup中添加一次,它将影响对$.ajax或基于Ajax的衍生产品(如$.get())的所有调用：

$.ajaxSetup(
{
    headers:
    {
        'X-CSRF-Token': $('input[name="_token"]').val()
    }
});

看看CSRF Protection.

希望这可以帮助.
