          模擬登陸csdn失敗,幫忙看下哪里有問題

          從圖中得知表單需要哪些數據
          938215-20160809204500793-1563778880.png

          下面的兩行代碼保存cookies

          session = requests.Session()
          response = session.get(url, headers=headers).content

          下面的代碼獲取表單所需數據

          soup = BeautifulSoup(response, "lxml")
          # 解析頁面獲取表單必須的數據
          lt = soup.find(attrs={"type": "hidden", "name": "lt"})['value']
          execution = soup.find(attrs={"type": "hidden", "name": "execution"})['value']
          event_id = soup.find(attrs={"type": "hidden", "name": "_eventId"})['value']

          最后還是登錄失敗


          下面是完整代碼

          可以通過捉包得出, 登錄url 不是https://passport.csdn.net/acc...
          而是這個https://passport.csdn.net/acc...
          session.post(url,data=post_data, headers=headers)
          中的url 改回 https://passport.csdn.net/acc... 就可以登錄
