知识点

• requests
• pprint

开发环境

• 版 本：python 3.8
  -编辑器：pycharm 2021.2

爬虫原理

• 作用：批量获取互联网数据(文本, 图片, 音频, 视频)
• 本质：一次次的请求与响应
  

案例实现

1. 导入所需模块

import requests
import pprint

2. 找到目标网址

打开开发者工具，选中Fetch/XHR，选中数据所在的标签，找到目标所在url

 https://www.weibo.com/tv/api/component?page=/tv/channel/4379160563414111/editor

3. 发送网络请求

headers = {
    'cookie': '',
    'referer': 'https://weibo.com/tv/channel/4379160563414111/editor',
    'user-agent': '',
}
data = {
    'data': '{"Component_Channel_Editor":{"cid":"4379160563414111","count":9}}'
}
url = 'https://www.weibo.com/tv/api/component?page=/tv/channel/4379160563414111/editor'
json_data = requests.post(url=url, headers=headers, data=data).json()

4. 获取数据

json_data_2 = requests.post(url=url_1, headers=headers, data=data_1).json()

5. 筛选数据

dict_urls = json_data_2['data']['Component_Play_Playinfo']['urls']
video_url = "https:" + dict_urls[list(dict_urls.keys())[0]]
print(title + "\t" + video_url)

6. 保存数据

video_data = requests.get(video_url).content
with open(f'video\\{title}.mp4', mode='wb') as f:
    f.write(video_data)
print(title, "爬取成功................")

完整代码

import requests
import pprint

headers = {
    'cookie': '添加自己的',
    'referer': 'https://weibo.com/tv/channel/4379160563414111/editor',
    'user-agent': '',
}
data = {
    'data': '{"Component_Channel_Editor":{"cid":"4379160563414111","count":9}}'
}
url = 'https://www.weibo.com/tv/api/component?page=/tv/channel/4379160563414111/editor'
json_data = requests.post(url=url, headers=headers, data=data).json()
print(json_data)

ccs_list = json_data['data']['Component_Channel_Editor']['list']
next_cursor = json_data['data']['Component_Channel_Editor']['next_cursor']
for ccs in ccs_list:
    oid = ccs['oid']
    title = ccs['title']
    data_1 = {
        'data': '{"Component_Play_Playinfo":{"oid":"' + oid + '"}}'
    }
    url_1 = 'https://weibo.com/tv/api/component?page=/tv/show/' + oid
    json_data_2 = requests.post(url=url_1, headers=headers, data=data_1).json()
    dict_urls = json_data_2['data']['Component_Play_Playinfo']['urls']
    video_url = "https:" + dict_urls[list(dict_urls.keys())[0]]
    print(title + "\t" + video_url)

    video_data = requests.get(video_url).content
    with open(f'video\\{title}.mp4', mode='wb') as f:
        f.write(video_data)
    print(title, "爬取成功................")
