fiddle python抓取微信公眾號文章
阿新 • • 發佈：2020-09-23
分析
1，先進行準備工作：使用fiddle抓包（大家可以自行百度怎麼使用哦）
2，開啟電腦端微信，找到需要爬取的公眾號
點選進入公眾號，再開啟fiddle，微信停留在這一步
**遇到的坑：
1，微信不能請求太頻繁，不然會無法進入文章頁面24小時
2，用fiddle抓取的這個連結有時效性，經測試大約30分鐘
測試程式碼如下
3，想讓爬取的url變成pdf需要使用pdfkit庫，大家可以自行百度哦
import requests,time data0 = time.time() while True: url = 'https://mp.weixin.qq.com/mp/profile_ext?action=getmsg&__biz=MzA5NjEwNjE0OQ==&f=json&offset=11&count=10&is_ok=1&scene=124&uin=MTczNjk0NDEwMw%3D%3D&key=827f3335bef33e45717c17a835620ed3e7c540ab72a526ab5b053adcaa860be393c02f9ac5dcd1f29e45d6568788ca024b2aef3a0ff57fea9324a750ff257637fdba0690f8531315bdfca09cb3b9face1b1a5eb7efd9a8fc4f6948dd63e5930be4109b6de50b4efea8dc446012adf7ea5d58ee9ee75620ef9b1d7086201a78dc&pass_ticket=jN5PzMHo4SdLo6xWe8i%2FvQ6x87AEnKHHtwMkpl%2FuH6TKwnoBj%2F01J3thBdOHmMTM&wxtoken=&appmsg_token=1075_HtI4fzr7%252F2AwFEgwfox68YcvhRovjfzSy9-Knw~~&x5=0&f=json' r = requests.get(url) if len(r.text) > 400: time.sleep(180) else: print("有效期為"+str(int(time.time()-data0)/60)+"分鐘") break
結果為
編寫程式碼
1，構造headers，使用這裡面的引數
