python - 如何将字符串列表插入到mongodb数据库中？

Question

database = mongo_connect()
un = str(session['username'])

database.game.insert({'host': session['username'],
    'player_list':[un]})

如果我这样做，那么当我检索player_list时，我会得到一个unicode列表。我怎样才能获得字符串列表？谢谢

因为mongodb stores data in bson format, and since bson is utf8-encoded, you'll get only unicode strings .

无论如何，您都可以将 unicode 编码为 str；

player_list = [x.encode('utf-8') for x in player_list]
