我一直收到此错误＆＃34; 500（内部服务器错误）发送@jquery.min.js：5ajax @jquery.min.js：5（匿名）@（索引）：260dispatch @jquery.min.js ：3v.handle @ jquery.min.js：3＆＃34;每当我尝试在laravel中使用ajax发布帖子请求时，我会真的很感激一些帮助。以下是我视图中的代码：

    <form action="" >

    <div class="switch-field">
    <h5>Academic Level</h5>
    <input class="changedVal" type="radio" id="highschool" name="academic_level" value="Highschool" />
    <label for="highschool">High School</label>
    <input class="changedVal" type="radio" id="college" name="academic_level" value="College" />
    <label for="college">College</label>
    <input class="changedVal" type="radio" id="university" name="academic_level" value="University" />
    <label for="university">University</label>
    <input class="changedVal" type="radio" id="masters" name="academic_level" value="Masters" />
    <label for="masters">Master's</label>
    <input class="changedVal" type="radio" id="phd" name="academic_level" value="Phd" />
    <label for="phd">PhD</label>
    </div>

    <div class="switch-field">
    <h5>Spacing</h5>
    <input class="changedVal" type="radio" id="double_spaced" name="spacing" value="Double Spaced" />
    <label for="double_spaced">Double Spaced</label>
    <input class="changedVal" type="radio" id="single_spaced" name="spacing" value="Single Spaced" />
    <label for="single_spaced">Single Spaced</label>
    </div>

    <div>
    <h5>No. of pages</h5>
    <input class="changedVal" type="number"  name="no_pages" min="1" max="10" value="1" />
    </div>

    <div class="switch-field" style="margin-bottom:25px;">
    <h5>Deadline</h5>
    <input class="changedVal" type="radio" id="14_days" name="deadline" value="14 Days" />
    <label for="14_days">14 Days</label>
    <input class="changedVal" type="radio" id="7_days" name="deadline" value="7 Days" />
    <label for="7_days">7 Days</label>
    <input class="changedVal" type="radio" id="5_days" name="deadline" value="5 Days" />
    <label for="5_days">5 Days</label>
    <input class="changedVal" type="radio" id="3_days" name="deadline" value="3 Days" />
    <label for="3_days">3 Days</label>
    <input class="changedVal" type="radio" id="48_hrs" name="deadline" value="48 Hrs" />
    <label for="48_hrs">48 Hrs</label>
    <input class="changedVal" type="radio" id="24_hrs" name="deadline" value="24 Hrs" />
    <label for="24_hrs">24 Hrs</label>
    </div>

    <input style="margin-left:-300px;margin-top:0px;width:200px;border:none;background-color:transparent;font-size:30px;color:#32c5d2;" type="text" id="testVal">

    <script type="text/javascript" >
    var coun=0;

    $('.changedVal').change(function(){

    var level=$('input[name=academic_level]:checked').val();
    var spacing=$('input[name=spacing]:checked').val();
    var pages=$('input[name=no_pages]').val();
    var deadline=$('input[name=deadline]:checked').val();

    var data={academic_level:level,spacing:spacing,pages:pages,deadline:deadline};

    console.log(data);
    $.ajax({
    url: '/pricecalculator',
    type: 'post',
    data: data,
    success: function(msg){

    console.log('data returned='+msg);

     $('#testVal').val(msg);
     }
     });
     });
     </script>

     </form>

以下代码是我的路线：

    Route::post('/pricecalculator', array('uses' => 'MainController@priceCalculator'));

以下代码是我的控制器：

   namespace App\Http\Controllers;

   use Illuminate\Http\Request;
   use App\Http\Requests;
   use Illuminate\Support\Facades\Input;
   use App\Http\Controllers\Controller;
   use App\Prices;
   use View;

   class MainController extends Controller
   {
   public function priceCalculator(Request $request)
   {
    $request->all();

    dd($request);
   }
   }

当您在laravel中发布帖子请求时，您必须在ajax标题中包含csrf token值，如：

$.ajax({
    url: 'login',
    method: 'post',
    data: {
        key: value
    },

    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    },
    success: function(response){

    }
});

如果没有这个，你将得到 500（内部服务器错误）
