Instagram 故事刮板：过程是什么？

Question

我正在尝试编写一个 Web scraping python 程序，该程序可以通过您的登录从用户那里获取故事。我想看看我是否能让它工作会很有趣，因为 4k Stogram 花钱只是为了更多的功能。

我登录成功了，但我不知道从这里去哪里。

from bs4 import BeautifulSoup
import json, random, re, requests, urllib.request
import urllib2

USERNAME = '*****'
PASSWD = '****'
account_purging = '****'

BASE_URL = 'https://www.instagram.com/accounts/login/'
LOGIN_URL = BASE_URL + 'ajax/'

headers_list = [

    ]

USER_AGENT = headers_list[random.randrange(0,(len(headers_list)+1))]

session = requests.Session()
session.headers = {'user-agent': USER_AGENT}
session.headers.update({'Referer': BASE_URL})
req = session.get(BASE_URL)
soup = BeautifulSoup(req.content, 'html.parser')
body = soup.find('body')

pattern = re.compile('window._sharedData')
script = body.find("script", text=pattern)

script = script.get_text().replace('window._sharedData = ', '')[:-1]
data = json.loads(script)

csrf = data['config'].get('csrf_token')
login_data = {'username': USERNAME, 'password': PASSWD}
session.headers.update({'X-CSRFToken': csrf})
login = session.post(LOGIN_URL, data=login_data, allow_redirects=True)

story_page = "https://www.instagram.com/stories" + "/" + account_purging

# stories url is:
request_headers_story = {
    "Accept:" : "video/webm,video/ogg,video/*;q…q=0.7,audio/*;q=0.6,*/*;q=0.5",
    "Accept-Language" : "en-US,en;q=0.5",
    "Connection" : "keep-alive",
    "DNT" : "1",
    "Host" : "scontent-ort2-1.cdninstagram.com",
    "Range" : "bytes=0-",
    "Referer" : story_page,
    "TE" : "Trailers",
    "User-Agent" : USER_AGENT
}

soup = session.post(story_page, data=request_headers_story, allow_redirects=True)
print(BeautifulSoup(soup.content, 'html.parser'))

我正在尝试获取 mp4 和 jpg 链接，并使用它稍后在数组或其他内容中下载。如果有什么可以指出我的方向，我将不胜感激。

我也在努力避免使用 api 因为，那只会让它变得无聊。

Answer 1

避免使用 api 解决此问题的更简单方法是使用 selenium。通过使用 selenium，您可以更快、更高效地登录并获取所需的图像和视频。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
#or driver = webdriver.Chrome()

注意：要抓取图片，您需要找到图片的 ID 或名称，然后执行以下操作：

driver.find_element_by_id("image_id")

或

driver.find_element_by_name("image_name")

如果您需要更多信息或说明，请查看 https://selenium-python.readthedocs.io/。

如果对您有帮助，请告诉我！
