Python爬虫系列17-批量抓取某短视频平台某用户的全部作品

实战

第一步：请求网络；获取到网站返回的数据内容

import requests

cookies = {
    'did': 'web_87ee5530f7dc26c5c05dfe66acf70e14',
    'didv': '1649420428219',

    'kuaishou.server.web_ph': '1add9f8e5ac33f374cfd8dba6cde9f596395',
}

headers = {
    'Accept-Language': 'zh-CN,zh;q=0.9',
    'Connection': 'keep-alive','Origin': 'https://www.kuaishou.com',

# 携带的数据
json_data = {
    'operationName': 'visionProfilePhotoList',
    'variables': {
        'userId': '3xjs47vsmgzxgnu',
        'pcursor': '',
        'page': 'profile',
    },
    'query': 'fragment photoContent on PhotoEntity {\n  id\n  duration\n  caption\n  likeCount\n  viewCount\n  realLikeCount\n  coverUrl\n  photoUrl\n  photoH265Url\n  manifest\n  manifestH265\n  videoResource\n  coverUrls {\n    url\n    __typename\n  }\n  timestamp\n  expTag\n  animatedCoverUrl\n  distance\n  videoRatio\n  liked\n  stereoType\n  profileUserTopPhoto\n  __typename\n}\n\nfragment feedContent on Feed {\n  type\n  author {\n    id\n    name\n    headerUrl\n    following\n    headerUrls {\n      url\n      __typename\n    }\n    __typename\n  }\n  photo {\n    ...photoContent\n    __typename\n  }\n  canAddComment\n  llsid\n  status\n  currentPcursor\n  __typename\n}\n\nquery visionProfilePhotoList($pcursor: String, $userId: String, $page: String, $webPageArea: String) {\n  visionProfilePhotoList(pcursor: $pcursor, userId: $userId, page: $page, webPageArea: $webPageArea) {\n    result\n    llsid\n    webPageArea\n    feeds {\n      ...feedContent\n      __typename\n    }\n    hostName\n    pcursor\n    __typename\n  }\n}\n',
}

response = requests.post('https://www.kuaishou.com/graphql', cookies=cookies, headers=headers, json=json_data)
print(response.json())

如果学习上有遇到问题，想联系我可以加v：yiyi990805（备注：阿里云tony）即可。

第二步：对数据进行提取和解析

for tony in response.json()['data']['visionProfilePhotoList']['feeds']:
        print(tony['photo'])

接下来，大家按照这种方式进行数据的提取就可以了 ；视频的地址链接就在该数据中。如果大家不会保存，可以看我前面写的爬虫系列文章，都有讲解如何保存视频文件的。
实践才是检验真理的唯一标准。
