Answer 1

Route::post('category', 'categoryController@create');

改成

Route::post('category', ['as' => 'category',  'uses' => 'categoryController@create']);

Answer 2

in view:

$.ajaxSetup({
headers: {
    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
        }
});

 <meta name="csrf-token" content="{{ csrf_token() }}" /> <input type="hidden" name="_token" value="{{ csrf_token() }}"> 

in controller:

 /**
 * Determine if the session and input CSRF tokens match.
 *
 * @param \Illuminate\Http\Request $request
 * @return bool
 */
protected function tokensMatch($request)
{
    // If request is an ajax request, then check to see if token matches token provider in
    // the header. This way, we can use CSRF protection in ajax requests also.
    $token = $request->ajax() ? $request->header('X-CSRF-Token') : $request->input('_token');

    return $request->session()->token() == $token;
}
