The required anti-forgery form field “__RequestVerificationToken” is not present Error in user Registration

Question

I am using Membership.create user function, then the following error is occurring,

The required anti-forgery form field \"__RequestVerifi

Answer 1

In my case I was getting this error while making an AJAX post, it turned out to be that the __RequestVerificationToken value wasn't being passed across in the call. I had to manually find the value of this field and set this as a property on the data object that's sent to the endpoint.

i.e.

data.__RequestVerificationToken = $('input[name="__RequestVerificationToken"]').val();

Javascript

$(document).on('click', '#myForm .submitButton', function () {
  var myData = { ... };
  myData.__RequestVerificationToken = $('#myForm input[name="__RequestVerificationToken"]').val();

  $.ajax({
    type: 'POST',
    url: myUrl,
    data: myData,
    contentType: 'application/x-www-form-urlencoded; charset=utf-8',
    dataType: 'json',
    success: function (response) {
      alert('Form submitted');
    },
    error: function (e) {
      console.error('Error submitting form', e);
      alert('Error submitting form');
    },
  });
  return false; //prevent form reload
});
