ajax通过 csrf

当你通过ajax提交post请求时会出现如下内容：

解决：

1、新建一个js文件

function getCookie(name) {

    var cookieValue = null;

    if (document.cookie && document.cookie !== '') {

        var cookies = document.cookie.split(';');

        for (var i = 0; i < cookies.length; i++) {

            var cookie = jQuery.trim(cookies[i]);

            // Does this cookie string begin with the name we want?

            if (cookie.substring(0, name.length + 1) === (name + '=')) {

                cookieValue = decodeURIComponent(cookie.substring(name.length + 1));

                break;

            }

        }

    }

    return cookieValue;

}

var csrftoken = getCookie('csrftoken');

function csrfSafeMethod(method) {

  // these HTTP methods do not require CSRF protection

  return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));

}

 

$.ajaxSetup({

  beforeSend: function (xhr, settings) {

    if (!csrfSafeMethod(settings.type) && !this.crossDomain) {

      xhr.setRequestHeader("X-CSRFToken", csrftoken);

    }

  }

});
