I've decided to implement my Rails site with only a single page load, and do everything else via AJAX. The problem is that the CSRF token which is generated in meta is invalidated once used to submit a signup or signin form. How can I update it without reloading the page?
推荐答案
您可以在您的Ajax调用的PUT，POST方法使用beforeSend如下图所示。
$阿贾克斯（{
键入：POST，
beforeSend：功能（XHR）{xhr.setRequestHeader（X-CSRF令牌'，$（'元[NAME =CSRF令牌]）ATTR（内容））}，
网址：您的网址，
数据：数据
}）;
You can use beforeSend like below in your ajax call for put, post methods.
$.ajax({
type: 'POST',
beforeSend: function(xhr) {xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'))},
url: your url,
data: data
});
