前言

今天的这个脚本，是一个别人发的外包，交互界面的代码就不在这里说了，但是可以分享下自动评论、自动点赞、自动关注、采集评论和视频的数据是如何实现的

开发环境

python 3.8 运行代码
pycharm 2021.2 辅助敲代码
requests 第三方模块

原理：

模拟客户端，向服务器发送请求

代码实现

1. 请求伪装

def __init__(self):
    self.headers = {
        'content-type': 'application/json',
        'Cookie': 'kpf=PC_WEB; kpn=KUAISHOU_VISION; clientid=3; did=web_ea128125517a46bd491ae9ccb255e242; client_key=65890b29; didv=1646739254078; _bl_uid=pCldq3L00L61qCzj6fytnk2wmhz5; userId=270932146; kuaishou.server.web_st=ChZrdWFpc2hvdS5zZXJ2ZXIud2ViLnN0EqABH2BHihXp4liEYWMBFv9aguyfs8BsbINQIWqgoDw0SimMkpXwM7PKpKdJcZbU12QOyeKFaG4unV5EUkkEswL0HnA8_A9z2ujLlKN__gRsxU2B5kIYgirTDPiVJ3uPN1sU9mqvog3auoNJxDdbKjVeFNK1wQ5HTM_yUvYvmWOx9iC8IKcvnmo9YnG_J9ske-t-wiCWMgSCA25HN6MRqCMxuhoSnIqSq99L0mk4jolsseGdcwiNIiC8rjheuewIA1Bk3LwkNIYikU2zobcuvgAiBbMnBuDixygFMAE; kuaishou.server.web_ph=55c7e6b2033ea94a3447ea98082642cd6f1a',
        'Host': 'www.ks.com',
        'Origin': 'https://www.ks.com',
        'Referer': 'https://www.ks.com/search/video?searchKey=%E9%BB%91%E4%B8%9D',
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.67 Safari/537.36',
    }
    self.url = 'https://www.ks.com/graphql'

2. 获取搜索内容的方法

def get_search(self, keyword, pcursor):
    """
    :param keyword: 关键词
    :param pcursor: 页码
    :return: 搜索作品
    """
    json = {

        'variables': {'keyword': keyword, 'pcursor': pcursor, 'page': "search"}
    }
    response = requests.post(url=self.url, json=json, headers=self.headers)
    json_data = response.json()
    print(json_data)
    return json_data

if __name__ == '__main__':
    kuaishou = KuaiShou()
    # 获取评论
    kuaishou.get_comments('3xzry7secwhunai', '')
    # 发布评论
    kuaishou.post_comment('爱你', '3xgz9zaku7hig96', '3xydesqbvtrvcuq')
    # 点赞
    kuaishou.is_like('3xydesqbvtrvcuq', '3xgz9zaku7hig96')
    # 关注
    kuaishou.is_follow('3xxhfqquuachnje')
    # 创作者信息
    kuaishou.get_userInfo('3xxhfqquuachnje')
    # 获取创作者作品
