使用Firefox和Firebug。在触发ajax请求时打开“Console”选项卡。使用DEBUG=True，你可以得到django错误页面作为响应，你甚至可以在控制台选项卡中看到ajax响应的渲染html。

然后你就知道误差是什么了。

One CSRF token is assigned to every session ( i.e. every time you log in). So before you wish to get some data entered by user and send that as ajax call to some function which is protected by csrf_protect decorator, try to find the functions that are being called before you are getting this data from user. E.g. some template must be being rendered on which your user is entering data. That template is being rendered by some function. In this function you can get csrf token as follows: csrf = request.COOKIES['csrftoken'] Now pass this csrf value in context dictionary against which template in question is being rendered. Now in that template write this line: Now in your javascript function, before making ajax request, write this: var csrf = $('#csrf').val() this will pick value of token passed to template and store it in variable csrf. Now while making ajax call, in your post data, pass this value as well : "csrfmiddlewaretoken": csrf

这将工作，即使你没有实现django表单。

实际上，这里的逻辑是:您需要从请求中获得的令牌。 因此，您只需要在登录后立即找出被调用的函数。一旦你有了这个令牌，要么进行另一个ajax调用来获取它，要么将它传递给一些可以通过ajax访问的模板。

你可以把这个js粘贴到你的html文件中，记住把它放在其他js函数之前

<script>
  // using jQuery
  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;
  }

  function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
  }

  $(document).ready(function() {
    var csrftoken = getCookie('csrftoken');
    $.ajaxSetup({
      beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
          xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
      }
    });
  });
</script>

与所选答案相关，只是想对所选答案进行补充。

在这个回答中，关于. ajaxsetup(…)的解决方案。在Django settings.py中，如果你有

CSRF_USE_SESSIONS = True

这将导致所选的答案根本不起作用。在实现所选答案的解决方案时，删除该行或将其设置为False对我有用。

有趣的是，如果你在Django settings.py中设置了以下内容

CSRF_COOKIE_HTTPONLY = True

此变量不会导致所选答案的解决方案停止工作。

CSRF_USE_SESSIONS和CSRF_COOKIE_HTTPONLY都来自这个官方的Django文档https://docs.djangoproject.com/en/2.2/ref/csrf/

(我没有足够的代表来评论，所以我张贴我的输入一个答案)

Non-jquery回答:

var csrfcookie = function() {
    var cookieValue = null,
        name = 'csrftoken';
    if (document.cookie && document.cookie !== '') {
        var cookies = document.cookie.split(';');
        for (var i = 0; i < cookies.length; i++) {
            var cookie = cookies[i].trim();
            if (cookie.substring(0, name.length + 1) == (name + '=')) {
                cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                break;
            }
        }
    }
    return cookieValue;
};

用法:

var request = new XMLHttpRequest();
request.open('POST', url, true);
request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');
request.setRequestHeader('X-CSRFToken', csrfcookie());
request.onload = callback;
request.send(data);

将这一行添加到jQuery代码中:

$.ajaxSetup({
  data: {csrfmiddlewaretoken: '{{ csrf_token }}' },
});

和完成。
