将Json导入数据框python

Question

我正在尝试将网页中的 JSON 导入数据框，这是我第一次尝试这样做，但我不明白我做错了什么。我想从 calendarEntries 中获取一个包含两列的数据框：productCode、settlement

import requests
import pandas as pd
import os
os.chdir('D:/')


def scrape(url):
    session = requests.Session()
    session.headers.update(
        {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:89.0) Gecko/20100101 Firefox/89.0'})
    time.sleep(rd.randint(0, 10))
    response = session.get(url, params={"_": int(time.time() * 1000)})
    return response


def main():
    option_url = f'https://www.cmegroup.com/CmeWS/mvc/ProductCalendar/Options/138'
    response = scrape(option_url)
    expiration=pd.read_json(response)
    print(expiration)
    
if __name__ == "__main__":
    main() 

Answer 1

pd.read_json 接受文件或缓冲区，但响应只是一个http响应，修改为pd.read_json(response.content)有效
