以bilibili直播弹幕为例

导入相关库

import requests,json,time

设置请求头

url = 'https://api.live.bilibili.com/xlive/web-room/v1/dM/gethistory?roomid=26568219&room_type=0'
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36',
    }

数据处理

response = json.loads(requests.get(headers=headers, url=url).text)
    response = response['data']['room']
    for i in response:
        text = i['text']
        name = i['nickname']
        timeline = i['timeline']
        result = f'[{timeline}] {name}: {text}'
        if result not in item:
            item.append(result)
            print(result)
        time.sleep(0.5)

将读取到的str类型（json）转化为dict数据，并从中取出想要的数据进行输出
