Answer 1

BeautifulSoup erfordert den zurückgegebenen Inhalt, nicht die komplette Antwort. Versuchen Sie opens.text mit:

opens = r.post(url=url, data=data) 
soup = BeautifulSoup(opens.text, 'lxml') 
print(soup) 

Answer 2

ich hatte diesen Fehler vor, und ich hatte die Antwort. gibt es viele Ursachen für diesen Fehler. Dies kann dadurch verursacht werden, dass die beiden Seiten der Verbindung nicht darüber entscheiden, ob während einer Keepalive-Verbindung die Verbindung abgelaufen ist oder nicht.

Um das Problem im Detail zu untersuchen, können Sie Wireshark verwenden.

oder Sie können einfach erneut anfordern oder erneut verbinden.
