即使提供csrf令牌后也出現403禁止錯誤

Question

以下是我的Ajax POST請求

這是在模板上

<script type="text/javascript">
    function submit_vote(){
        callback = function(data){
            alert(data.message);
        };

        $.post("{{request.get_full_path}}vote",{
            "rating" : $('#{{hash_id}}').raty('score')
        }, callback, "json");
    }
</script>

<div class="rating" id="{{hash_id}}" onclick="submit_vote()"></div>

在視圖上，就在這里

這是呈現存在Ajax腳本的模板的視圖

@csrf_protect
def show_rating(request, **kwargs):
    ....
    ....
    return render_to_response("rating.html",
                context,
                context_instance = RequestContext(request))

這是采用POST請求的視圖

@login_required
@csrf_protect
def submit_vote(request, **kwargs):
    if not request.method == "POST":
        raise Http404

    ...
    ...

    data = {"error" : False, "message" : "Thanks"}
    data = simplejson.dumps(data)
    return HttpResponse(data, mimetype="application/javascript")

嘗試上面的代碼后，我得到403禁止錯誤。通過使用django文檔，我向現有代碼中添加了另一個腳本（位於頂部）

<script type="text/javascript">
function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
function sameOrigin(url) {
    // test that a given url is a same-origin URL
    // url could be relative or scheme relative or absolute
    var host = document.location.host; // host + port
    var protocol = document.location.protocol;
    var sr_origin = '//' + host;
    var origin = protocol + sr_origin;
    // Allow absolute or scheme relative URLs to same origin
    return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||
        (url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||
        // or any other URL that isn't scheme relative or absolute i.e relative.
        !(/^(\/\/|http:|https:).*/.test(url));
}
$.ajaxSetup({
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && sameOrigin(settings.url)) {
            // Send the token to same-origin, relative URLs only.
            // Send the token only if the method warrants CSRF protection
            // Using the CSRFToken value acquired earlier
            xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
    }
});
</script>

現在我得到

Uncaught ReferenceError: csrftoken is not defined 

錯誤..

如何解決？ 實際上，我不了解Ajax，Jquery和JS ..只是試圖從網絡教程中構建一個簡單的請求！

Answer 1

您可以只在帖子請求中發送一個csrfmiddlewaretoken ，它應該是固定的。

$.post("{{request.get_full_path}}vote",{
        "rating" : $('#{{hash_id}}').raty('score'),
        "csrfmiddlewaretoken": {{csrf_token}},
    }, callback, "json");

您不需要任何其他腳本。
