python爬取微博内容json部分报错求助

rookieicrack

根据关键词用python爬取微博内容
comments_ID = []

def get_title_id():
    for page in range(2, 45):  # 每个页面大约有9个话题
        headers = {
            "User-Agent": UserAgent().chrome  # chrome浏览器随机代{过}{滤}理
        }
        time.sleep(1)
        # 该链接通过抓包获得(这里需要更改成你的话题url)
        api_url='https://m.weibo.cn/api/container/getIndex?containerid=231583&page_type=searchall='+str(page)
        print(api_url)
        rep1 = requests.get(url=api_url, headers=headers)
        rep=json.loads(rep1.text)
        # 获取ID值并写入列表comment_ID中
        for json1 in rep['data']['cards']:
            comment_ID = json1["card_group"][0]['mblog']['id']
            comments_ID.append(comment_ID)


报错内容如下`D:\software\python\python.exe D:/BaiduNetdiskDownload/weibo/weibotopic.py
https://m.weibo.cn/api/container/getIndex?containerid=231583&page_type=searchall=2
Traceback (most recent call last):

comment_ID = json1["card_group"][0]['mblog']['id']
KeyError: 'card_group'Process finished with exit code 1

改为
for json1 in rep['data']['cards']:
    comment_ID = json1[0]["card_group"][0]['mblog']['id']
    comments_ID.append(comment_ID)
又报错
D:\software\python\python.exe D:/BaiduNetdiskDownload/weibo/weibotopic.py
