在CSRF攻击中，无辜的终端用户被攻击者欺骗，提交了一个他们不打算提交的web请求

选项1

from django.views.decorators.csrf import csrf_exempt
from django.http.response import JsonResponse


@csrf_exempt
def commentDeletePost(request):
    if request.is_ajax() and request.method == 'POST':
        try:
            comment = Comment.objects.get(pk=request.POST['pk'])
            if comment.author != request.user:
                return JsonResponse({'e': 'Forbidden'}, status=403) 
            comment.delete()
            return JsonResponse({}, status=200)
        execpt Comment.DoesNotExist:
            return JsonResponse({'e': 'Not Found'}, status=404)

选项2

<div id="csrf">
    {% csrf_token %}
</div>
<script type="text/javascript">
    window.crud = {
        commentDelete: function(
            pk, 
            success,
            error, 
        ){
            $.ajax({
                headers: {'X-CSRFToken': document.getElementById('csrf').querySelector('input').value},
                type: "POST", 
                url: "{% url 'comment-delete-post' %}",
                data: {
                    pk: pk,
                }, 
                success: success, 
                error: error,
            })
        }, 
    }
</script>

two options have its own advantage. First option will discard csrf token, which will not protecte your site from csrf attacks, but it will allow user to send more than one request with same Ajax function. the second option will restrict user to send one Ajax request only since csrf token can only be used once, but it is more secure. I personally prefer option 1, since Ajax functions such as like, star, unlike requires more than one Ajax call, and it is not a risky function to allow user call more than once.

因为它没有在当前的答案中任何地方说明，如果你没有将js嵌入到你的模板中，最快的解决方案是:

设置<script type="text/javascript">窗口。CSRF_TOKEN = "{{CSRF_TOKEN}}";</script>在你的模板中引用script.js文件，然后将csrfmiddlewaretoken添加到你的js文件中的数据字典中:

$.ajax({
            type: 'POST',
            url: somepathname + "do_it/",
            data: {csrfmiddlewaretoken: window.CSRF_TOKEN},
            success: function() {
                console.log("Success!");
            }
        })

{% csrf_token %}在<form></form>内放置html模板

翻译过来就是:

<input type='hidden' name='csrfmiddlewaretoken' value='Sdgrw2HfynbFgPcZ5sjaoAI5zsMZ4wZR' />

所以为什么不像这样在你的JS中grep它:

token = $("#change_password-form").find('input[name=csrfmiddlewaretoken]').val()

然后传递它，例如做一些POST，比如:

$.post( "/panel/change_password/", {foo: bar, csrfmiddlewaretoken: token}, function(data){
    console.log(data);
});

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>

将这一行添加到jQuery代码中:

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

和完成。
