Question

尝试将数据发布到数据库时，我一直收到此消息。以下是错误页面，控制器，型号，路由，视图和javascript代码。

通过研究该主题，我找到了一些解决方案，这些建议表明人们在混合发布和获取请求。这里不是这样吗？坦克帮你！

AjaxController.php

<?php

namespace App\Http\Controllers;

use Validator;

use Illuminate\Http\Request;

use App\DataTable;

use DataTables;

class AjaxController extends Controller
{
    public function index()
    {
        return view('ajax');
    }

    public function getData()
    {
        $data = DataTable::select('name', 'email');

        return DataTables::of($data)->make(true);
    }

    public function postData(Request $request)
    {
        $validation = Validator::make($request->all(), [
        'name' => 'required',
        'email' => 'required',
      ]);

        $errorArray = array();
        $succesOutput = '';

        if ($validation->fails()) {
            foreach ($validation->messages()->getMessages() as $field_name => $messages) {
                $errorArray = $messages;
            }
        } else {
            if ($request->get('buttonAction') == 'insert') {
                $data = new DataTable([
              'name' => $request->get('name'),
              'email' => $request->get('email')
            ]);

                $data->save();

                $succesOutput = '<div class="alert alert-succes">Tilføjet</div>';
            }
        }

        $output = array(
          'error' => $errorArray,
          'succes' => $succesOutput
        );
        echo json_encode($output);
    }
}

DataTable.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class DataTable extends Model
{
    protected $fillable = [
    'name', 'email'
  ];
}

Route::get('/ajax', 'AjaxController@index')->name('ajax');
Route::get('/ajax/getdata', 'AjaxController@getData')->name('ajax.getData');
Route::post('/ajax/postdata', 'AjaxController@postData')->name('ajax.postData');
