如何在Django中通过AJAX POST发送包含数组的对象

标签: arrays ajax django post

当用户点击按钮时,我试图通过Django中的AJAX POST发送一个带有数组的对象。我按照Django docs上的说明进行了操作。我试图在视图中使用logger.debug()查看数组中的特定指标,但无法访问内容。如何访问数组中的特定元素?

我的AJAX ......

var tags_selected = [1,2,3,4]

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;
}

var csrftoken = getCookie('csrftoken');

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

$.ajaxSetup({
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
            xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
    }
});

$("#filter").click(function(){
  $.ajax({
    type: 'POST',
    url: "/pensieve/filtertags",
    data: {'tags': tags_selected},
    success: function(res){
      console.log(res)
    },
    dataType: "json"
  });
})

我的观点......

def filter_tags(request):
    logger.debug(request.POST)
    return HttpResponse(json.dumps({'response': 111}), content_type="application/json")

我的DEBUG登录终端...

DEBUG - 2016-05-06:17:15:50 - <QueryDict: {u'tags[]': [u'142', u'122', u'138']}>

您可以使用printMessage方法获取tags[]数组的值。

示例:

getlist()
