前端js

var data = Array();
data.push({'a': 1, 'b': 2})
$.ajax({
    url: '.....',
    type: 'post',
    data: {'dataList': JSON.stringify(data)},
    success: function (res){
        .....  
    }
})

后端django

import json
.....
def ..():
      dataList = request.POST.get('dataList')
      print(json.loads(dataList)[0])

输出：{'a': 1, 'b': 2}
