用yui设置Django CSRF_TOKEN，但控制台显示“ django.request禁止（CSRF令牌丢失或不正确。）”。

Question

I use this code in html:

 <script>
  YUI().use('node', function(Y){
      var token = Y.Node.create("{% csrf_token %}");
      YUI.Env.CSRF_TOKEN = token._node.firstChild.getAttribute('value');;
  });
 </script>

And I use some javascript code to send POST method:

Y.io('http://10.0.3.71/dashboard/send_t2_data', {
        method: 'POST',
        data: {'name':'123456'},
        headers: {
                'Content-Type': 'application/json',
                },
        on: {
            success: function(id, response) {

            },
            failure: function(id, response) {

            }
         }
});

But the console says django.request Forbidden (CSRF token missing or incorrect.): /dashboard/send_t2_data when I submit all data.

I follow by the official document to edit YUI.Env.CSRF_TOKEN. But it seems that there is something wrong about my code. Why do I configure the environment variable named YUI.Env.CSRF_TOKEN but it does not effective?

Could someone helps me? Thanks a lot!

I'm not a YUI specialist but it seems you've forgetten the header X-CSRFToken with the csrftoken cookie.

So get the csrftoken cookie dans set the request header X-CSRFToken with the value. In pure javascript it gave (copy/paste from a project of mine):

var xhr = new XMLHttpResquest();
xhr.open('POST', YOUR-URL, YOU-DATA-AS-STRING);
xhr.setRequestHeader("X-CSRFToken", getCSRFCookie());
xhr.send(null);

If I understand your code :

Y.io('http://10.0.3.71/dashboard/send_t2_data', {
        method: 'POST',
        data: {'name':'123456'},
        headers: {
                'Content-Type': 'application/json',
                'X-CSRFToken': getcookie('csrftoken')
        },
        on: {
            success: function(id, response) {

            },
            failure: function(id, response) {

            }
         }
});

where the function getcookie('csrftoken') get the cookie named csrftoken
