Question

我想在AJAX中将一组数据发布到Django-Site。来自Javascript的代码：

var arr = {};
arr["first"] = "first";
arr["second"] = "second";
arr["third"] = "third";
var success = ""
    var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
     var rawtext = xmlhttp.responseText;

     document.getElementById("myDiv").innerHTML= jsonToHTMLTable(rawtext);
    }
  }
xmlhttp.open("POST","/AJAX?modus=create");  
xmlhttp.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
alert(JSON.stringify(arr));
xmlhttp.send({data:JSON.stringify(arr)});

但是当我调试（使用Eclipse）时，我没有看到数组或其他有用的字段。

这是来自django的代码：

def AJAX(request):
if request.method == 'POST':
    method = request.REQUEST.get("modus","")
    if method == 'create':
        test = request.POST['data']

如何访问我的数据？

我发现这部分错了（Javascript）：

这是新的JavascriptPart（适用于我）：

var arr = {};
arr["first"] = "first";
arr["second"] = "second";
arr["third"] = "third";
var success = ""
$.ajax({
type: "POST",
url: "/AJAX?modus=create",
data: {"data": JSON.stringify(arr)},
success: success,
dataType: "application/json",
headers: {"X-CSRFToken": getCookie('csrftoken')}
});

这是django-part（观点）：

def AJAX(request):
  if request.method == 'POST':
      method = request.REQUEST.get("modus","")
      if method == 'create':
          data = request.POST.get('data');

在Django中没有来自Ajax的POST数据
