シンプルな ajax 投稿リクエストがあります。リクエストが送信されます。しかし、view.py で request.POST を出力すると、次のように表示されるのはなぜですかrequest.POST: <QueryDict: {}>
。
if (start <= end) {
// fire a request to /tryit
var args = {
type: "POST",
url: "/tryit/",
data: {'x':x1, 'y': y1},
error: function() {
console.log("Error occurs");
},
success: function() {
console.log("save_modification works");
},
complete:done
};
$.ajax(args);
alert("ajax request is sent");
}
views.py で、
def tryit(request):
print "request: ", request
リクエスト情報を印刷したときの出力は次のとおりです。出力は以下のように含まれます。

But when I use fiddler, I can see the query parameter string. I am stuck here for a day. Please help. Thanks.
新しいアップデート: Chrome を使用していますが、[ネットワーク] タブに内部サーバー エラーがあり、イニシエータが jquery.min.js:16 であると表示されます。私はこの情報を理解していません。これには何らかの情報が含まれていますか?
POST から GET に変更すると、サーバーがクエリ パラメータを受け取ることができます。しかし、POST を使用すると、クエリ パラメーターを投稿できません。どのように説明できますか?
