Test (method)); } $.ajaxsetup ({beforesend:function (XHR, settings) {if(!csrfsafemethod (Settings.type) &&!this.crossdomain) {Xhr.setrequestheader ("X-csrftoken", Csrftoken);        }            }        }); function do () {$.ajax ({URL:"/app01/test/", Data:{id:1}, type:'POST', Success:function (data) {Console.log (data);          }            }); }    </script></body>
