一个简单的ajax请求,一个简单的ajax请求发布为空

我有一个简单的ajax帖子请求。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: 。

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

这是打印请求信息时的输出。输出如下：

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，在网络选项卡中，它表示存在内部服务器错误，启动器为jquery.min.js：16。我不会透露这些信息。这包含一些信息吗？

如果我从POST更改为GET，服务器可以接收查询参数。但是如果我使用POST，则无法发布查询参数。怎么解释呢？
