I have created a form which is having a lot of fields and user can create an unlimited field in it. If a user spends more time on it CSRF token get expires and when he clicks on the submit LARAVEL return the error CSRF token mismatch. So how can I get new CSRF token by using ajax call so I can update the CSRF on a regular time of interval? I can not refresh or reload the form.

我创建了一个包含大量字段的表单,用户可以在其中创建无限字段。 如果用户花费更多时间,CSRF令牌将过期,当他点击提交LARAVEL时,返回错误CSRF令牌不匹配。 那么如何通过使用ajax调用获取新的CSRF令牌,以便我可以定期更新CSRF? 我无法刷新或重新加载表单。

    Just add this to your script

    <script type="text/javascript">
                    headers: {
                        'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')

    And make sure you have added token to your meta tag like below.

    <meta name="_token" content="{!! csrf_token() !!}" />

    I hope this will work for you.

    In below code you can get new token after login by regenerate() method and return response csrf_token().

    Your Controller inside the function
    public function refreshToken(Request $request)
         return response()->json([
    Javascript :
              url: "{{url('refresh-token')}}",
              type: 'get',
              dataType: 'json',
              success: function (result) {
                  $('meta[name="csrf-token"]').attr('content', result.token);
                      headers: {
                           'X-CSRF-TOKEN': result.token
               error: function (xhr, status, error) {
