本篇代码提供者: 青灯教育-巳月老师
知识点:
- 动态数据抓包
- requests发送请求
- json数据解析
开发环境:
运行代码
- python 3.8
辅助敲代码
- pycharm 2021.2
第三方模块
- requests
如果安装python第三方模块:
- win + R 输入 cmd 点击确定, 输入安装命令 pip install 模块名 (pip install requests) 回车
- 在pycharm中点击Terminal(终端) 输入安装命令
如何配置pycharm里面的python解释器?
选择file(文件) >>> setting(设置) >>> Project(项目) >>> python interpreter(python解释器)
点击齿轮, 选择add
添加python安装路径
pycharm如何安装插件?
选择file(文件) >>> setting(设置) >>> Plugins(插件)
点击 Marketplace 输入想要安装的插件名字 比如:翻译插件 输入 translation / 汉化插件 输入 Chinese
选择相应的插件点击 install(安装) 即可
安装成功之后 是会弹出 重启pycharm的选项 点击确定, 重启即可生效
基本思路流程（通用）
- 发送请求
- 获取数据
- 解析数据
- 保存数据
代码
导入模块
import requests # 发送请求 访问网站
import re
加入伪装
url = 'https://www.kuaishou.com/graphql'
# 伪装
headers = {

# 传数据
for page in range(1, 10):
json = {
'operationName': "visionSearchPhoto",
'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 visionSearchPhoto($keyword: String, $pcursor: String, $searchSessionId: String, $page: String, $webPageArea: String) {\n visionSearchPhoto(keyword: $keyword, pcursor: $pcursor, searchSessionId: $searchSessionId, page: $page, webPageArea: $webPageArea) {\n result\n llsid\n webPageArea\n feeds {\n ...feedContent\n __typename\n }\n searchSessionId\n pcursor\n aladdinBanner {\n imgUrl\n link\n __typename\n }\n __typename\n }\n}\n",

}
1. 发送请求
response = requests.post(url=url, headers=headers, json=json)
2. 获取数据
<Response [200]>: 请求成功
feeds = response.json()['data']['visionSearchPhoto']['feeds']
for feed in feeds:
author_id = feed['author']['id']
photo_id = feed['photo']['id']
print(author_id, photo_id)
caption = feed['photo']['caption']
photoUrl = feed['photo']['photoUrl']
print(caption, photoUrl)
caption = re.sub('[\\/:"?<>|\\n]', '', caption)
json_like = {
'operationName': "visionVideoLike",
'query': "mutation visionVideoLike($photoId: String, $photoAuthorId: String, $cancel: Int, $expTag: String) {\n visionVideoLike(photoId: $photoId, photoAuthorId: $photoAuthorId, cancel: $cancel, expTag: $expTag) {\n result\n __typename\n }\n}\n",
'variables': {
'cancel': 0,
'expTag': "1_i/2005246154318902369_xpcwebsearchxxnull0",
'photoAuthorId': author_id,
'photoId': photo_id
}
}
resp_ = requests.post(url=url, headers=headers, json=json_like)
# video_data = requests.get(photoUrl).content
# with open(f'video/{caption}.mp4', mode='wb') as f:
# f.write(video_data)
