关于动态爬取json格式文件

[96Jennifer]

请问朋友们知道为什么打印text显示jQuery,里面的data为null?
我跟着视频做的博主data里面都是字典表内容，这个是我的

import requests

headers={'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36'}
for i in range(1,2):
    param = {
        'cb': ' jQuery112408933494064226006_1636169759698',
        'pn': f' {i}',
        'pz': ' 20',
        'po': ' 1',
        'np': ' 1',
        'ut': ' bd1d9ddb04089700cf9c27f6f7426281',
        'fltt': ' 2',
        'invt': ' 2',
        'fid': ' f3',
        'fs': ' m:0 t:80',
        'fields': ' f1,f2,f3,f4,f5,f6,f7,f8,f9,f10,f12,f13,f14,f15,f16,f17,f18,f20,f21,f23,f24,f25,f22,f11,f62,f128,f136,f115,f152',
        '_': '1636169759852'
    }
    url = "http://49.push2.eastmoney.com/api/qt/clist/get"
    r = requests.get(url, params=param, headers=headers)
    print(r.text)

不知道哪里有问题？求解答。网址为“东方财富网”

@96jennifer 原因找到了
因为param中批量加入引号，引号与内容有空格，
更新代码
