我有一个简单的 ajax 发布请求。请求已发送。但是为什么当我在views.py中打印request.POST时,它会说: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");
}
在views.py中,
def tryit(request):
print "request: ", request
这是我打印请求信息时的输出。输出包括如下。

But when I use fiddler, I can see the query parameter string. I am stuck here for a day. Please help. Thanks.
新更新:我使用 chrome,在 Network 选项卡中,它说存在内部服务器错误,并且发起程序是 jquery.min.js:16。我不理解这些信息。这是否包含一些信息?
如果我从 POST 更改为 GET,则服务器可以接收到查询参数。但是如果我使用 POST,则无法发布查询参数。怎么解释呢?
