Front-end ajax:

data = {};
$.ajax({
    type: "post",
    url: "url",
    dataType: "json",
    data: JSON.stringify(data),
    success: function(result) {
    }
});

Backend value:

import json
data = json.loads(request.body)
print data['key']

You must first determine what the content you pass to the backend looks like. It cannot be directly json.loads
Assume that the source code of the view corresponding method is as follows

def test(req):
    print(req.POST)   # 通过输出看看前端传过来的数据是什么
    return HttpResponse('test')

Only the json format that conforms to '{"aa":"xxx"...}' can be recognized and deserialized by json.loads. If the result returned is not like this json Format, then you need to adjust the front-end ajax to be able to construct such data. Specifically, you can construct it through dataType: json or through string splicing. For details, you can Google it yourself: ajax passes json data
