Django CSRF检查Ajax POST请求失败

通过我的AJAX帖子，我可以使用一些帮助来遵守Django的CSRF保护机制。我遵循了这里的说明:

http://docs.djangoproject.com/en/dev/ref/contrib/csrf/

我已经复制了他们在该页面上的AJAX示例代码:

http://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax

我把一个警告打印getCookie('csrftoken')的内容之前的xhr。setRequestHeader调用，它确实被一些数据填充。我不确定如何验证令牌是正确的，但我被鼓励它正在寻找和发送一些东西。

但是Django仍然拒绝我的AJAX帖子。

这是我的JavaScript:

$.post("/memorize/", data, function (result) {
    if (result != "failure") {
        get_random_card();
    }
    else {
        alert("Failed to save card data.");
    }
});

下面是我从Django中看到的错误:

[23/Feb/2011 22:08:29] "POST / remember / HTTP/1.1" 403 2332

我肯定我遗漏了什么，也许很简单，但我不知道是什么。我在SO周围搜索了一下，看到了一些关于通过csrf_exempt装饰器关闭视图的CSRF检查的信息，但我发现那没什么吸引力。我已经尝试过了，它是有效的，但如果可能的话，我宁愿让我的POST以Django设计的方式工作。

为了以防有用，这里是我的视图正在做的事情的要点:

def myview(request):

    profile = request.user.profile

    if request.method == 'POST':
        """
        Process the post...
        """
        return HttpResponseRedirect('/memorize/')
    else: # request.method == 'GET'

        ajax = request.GET.has_key('ajax')

        """
        Some irrelevent code...
        """

        if ajax:
            response = HttpResponse()
            profile.get_stack_json(response)
            return response
        else:
            """
            Get data to send along with the content of the page.
            """

        return render_to_response('memorize/memorize.html',
                """ My data """
                context_instance=RequestContext(request))

谢谢你的回复!

下面是Django提供的一个简单的解决方案:

<script type="text/javascript">
// using jQuery
var csrftoken = jQuery("[name=csrfmiddlewaretoken]").val();

function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
// set csrf header
$.ajaxSetup({
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
            xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
    }
});

// Ajax call here
$.ajax({
    url:"{% url 'members:saveAccount' %}",
    data: fd,
    processData: false,
    contentType: false,
    type: 'POST',
    success: function(data) {
        alert(data);
        }
    });
</script>

如果你的表单在不使用JS的情况下可以在Django中正确地发布，你应该可以使用ajax逐步增强它，而不需要任何修改或混乱地传递csrf令牌。只需序列化整个表单，它将自动拾取所有表单字段，包括隐藏的csrf字段:

$('#myForm').submit(function(){
    var action = $(this).attr('action');
    var that = $(this);
    $.ajax({
        url: action,
        type: 'POST',
        data: that.serialize()
        ,success: function(data){
            console.log('Success!');
        }
    });
    return false;
});

我已经用Django 1.3+和jQuery 1.5+进行了测试。显然，这适用于任何HTML表单，而不仅仅是Django应用程序。

如果有人正在与axios作斗争，这有助于我:

import axios from 'axios';

axios.defaults.xsrfCookieName = 'csrftoken'
axios.defaults.xsrfHeaderName = 'X-CSRFToken'

使用Django 3.1.1和我尝试的所有解决方案都失败了。但是，在POST体中添加“csrfmiddlewaretoken”键是有效的。这是我打的电话:

$.post(url, {
  csrfmiddlewaretoken: window.CSRF_TOKEN,
  method: "POST",
  data: JSON.stringify(data),
  dataType: 'JSON',
});

在HTML模板中:

<script type="text/javascript">
  window.CSRF_TOKEN = "{{ csrf_token }}";
</script>

I've just encountered a bit different but similar situation. Not 100% sure if it'd be a resolution to your case, but I resolved the issue for Django 1.3 by setting a POST parameter 'csrfmiddlewaretoken' with the proper cookie value string which is usually returned within the form of your home HTML by Django's template system with '{% csrf_token %}' tag. I did not try on the older Django, just happened and resolved on Django1.3. My problem was that the first request submitted via Ajax from a form was successfully done but the second attempt from the exact same from failed, resulted in 403 state even though the header 'X-CSRFToken' is correctly placed with the CSRF token value as well as in the case of the first attempt. Hope this helps.

问候,

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>
