Get Blog Comments

It should be enough to set the size to 1000, if it is not enough, adjust it according to the actual situation.

def comment_list(username,article_id):
    url = f'https://blog.csdn.net/phoenix/web/v1/comment/list/{
      
      article_id}?page=1&size=1000'
    headers = {
    
    
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.140 Safari/537.36 Edge/18.17763',
        'Cookie': f'UserName={
      
      username}'
    }
    res = requests.get(url, headers=headers)
    comments = res.json()['data']['list']
    comment_dicts = []
    for comment in comments:
        if comment['info']['parentId'] == 0:
            content = comment['info']['content']
            userName = comment['info']['userName']
            nickName = comment['info']['nickName']
            comment_dict = {
    
    
                'userName': userName,
                'nickName': nickName,
                'content': content
            }
            comment_dicts.append(comment_dict)
    return comment_dicts

Extract users

There are several points to consider:

• exclude the author himself
• Have you commented as requested
• Extracted user duplicates
• The number of users to be extracted is less than the required number (of course, under normal circumstances, 3 or 5 are enough)

def select_users(username,base_content,comment_ds,num):
    users = []
    if base_content is None:
        for item in comment_ds:
            users.append(item['userName'])
    else:
        for item in comment_ds:
            # 筛选出按照要求评论的用户
            if item['content'] == base_content:
                users.append(item['userName'])
    # 移除作者自己
    if username in users:
        users.remove(username)
    if num > len(set(users)):
        print('待抽取用户个数不足抽取的个数！')
    else:
        selected_users = random.sample(users, num)
        if len(selected_users) != len(set(selected_users)):
            print('存在重复用户，请重新抽取！')
        else:
            print(f'中奖用户:{
      
      selected_users}')

program entry

Here is a demonstration of this blog by Boss Chen:

if __name__ == '__main__':
    # 你的username
    username = 'weixin_47343544'
    # 参与抽奖活动的博客id
    article_id = 131788124
    # 你要求的评论内容
    base_content = '学java就找陈老老老板'
    # base_content = None
    # 抽取人数
    num = 3
    comment_ds = comment_list(username, article_id)
    select_users(username, base_content, comment_ds, num)

Effect

哈哈，竟然抽到了自己。

Winning users: ['m0_64280701', 'H1727548', 'weixin_38093452']
