Python爬蟲采集微博視頻數(shù)據(jù)

更新時(shí)間：2021年12月03日 16:00:42 作者：松鼠愛吃餅干

這篇文章主要介紹了利用Python爬蟲采集微博的視頻數(shù)據(jù)，文中有非常詳細(xì)的代碼示例,對(duì)正在學(xué)python的小伙伴們有很好地幫助,需要的朋友可以參考下

前言

隨時(shí)隨地發(fā)現(xiàn)新鮮事！微博帶你欣賞世界上每一個(gè)精彩瞬間，了解每一個(gè)幕后故事。分享你想表達(dá)的，讓全世界都能聽到你的心聲！今天我們通過python去采集微博當(dāng)中好看的視頻！

沒錯(cuò)，今天的目標(biāo)是微博數(shù)據(jù)采集，爬的是那些好看的小姐姐視頻

知識(shí)點(diǎn)

requests

pprint

開發(fā)環(huán)境

版本：python 3.8

-編輯器：pycharm 2021.2

爬蟲原理

作用：批量獲取互聯(lián)網(wǎng)數(shù)據(jù)(文本, 圖片, 音頻, 視頻)

本質(zhì)：一次次的請(qǐng)求與響應(yīng)

?案例實(shí)現(xiàn)

1. 導(dǎo)入所需模塊

import requests
import pprint

2. 找到目標(biāo)網(wǎng)址

打開開發(fā)者工具，選中Fetch/XHR，選中數(shù)據(jù)所在的標(biāo)簽，找到目標(biāo)所在url

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

3. 發(fā)送網(wǎng)絡(luò)請(qǐng)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. 獲取數(shù)據(jù)

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

5. 篩選數(shù)據(jù)

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. 保存數(shù)據(jù)

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................")

完整代碼

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................")
