推荐答案

我有同样的问题，并通过添加 ensure_csrf_cookie decorator 到您的视图：

I had the same problem, and resolved it by adding the ensure_csrf_cookie decorator to your view:

 from django.views.decorators.csrf import ensure_csrf_cookie
 @ensure_csrf_cookie
 def yourView(request):
     #...

它会在浏览器cookie中设置csrftoken，并且可以像这样创建ajax

It will set csrftoken in browser cookie and you can make ajax like this

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));
}
$.ajaxSetup({
    crossDomain: false, // obviates need for sameOrigin test
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type)) {
            xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
        }
    }
});
$.ajax({
        url: url,
        type: type,
        async: async,
        data: data,
        error: function (e) {},
        success: function (data) {
                returnFunction(data);
            }
    });
