pymysql: TypeError: not all arguments converted during string formatting

Question

我一直在用头撞墙。我无法让这个插入查询工作。是因为我插入了多种数据类型（int、bool、strings、NoneType）并且我正在使用 %s 吗？任何帮助将不胜感激。谢谢！

class DBWork(object):
    def __init__(self, attackerip=None, victimip=None, shunlen=15, shuncount=1, shunreason=None, shunepoch=None,
                 shunerrorbool=False, shunerror=None, paloaddedepoch=None, paloremovedepoch=None,
                 lastshunlen=15):
        self.Id = None
        self.attackerip = attackerip
        self.victimip = victimip
        self.shunlen = shunlen
        self.shuncount = shuncount
        self.shunreason = shunreason
        self.shunepoch = shunepoch
        self.shundatetime = 'need to build this'
        self.shunerrorbool = shunerrorbool
        self.shunerror = shunerror
        self.paloaddedepoch = paloaddedepoch
        self.paloremovedepoch = paloremovedepoch
        self.lastshunlen = lastshunlen
        self.shunlen = shunlen
        self.newshunlen = lastshunlen * shuncount

    def HistoryInsert(self):
        insert_query = (
            "INSERT INTO `autoshun`.`shunhistory` "
            "(Id, attackerip, victimip, shunlen, shuncount, shunreason, shunepoch, shundatetime, shunerrorbool, "
            "shunerror, paloaddedepoch, paloremovedepoch) "
            "VALUES "
            "(NULL, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s );"
        )
        values = [None, self.attackerip, self.victimip, self.shunlen, self.shuncount, self.shunreason, self.shunepoch,
                  self.shundatetime, self.shunerrorbool, self.shunerror, self.paloaddedepoch, self.paloremovedepoch]
        print values
        self.cur.execute(insert_query, values)

sample = DBWork(attackerip='1.1.1.15', victimip='2.2.2.2',  shunlen=15, shuncount=1, shunreason='hax', shunerrorbool=True)

sample.DBConnect()
sample.HistoryInsert()

传入的值：

values = [None, '1.1.1.15', '2.2.2.2', 15, 1, 'hax', 'NULL', 'need to build this', False, 'NULL', 'NULL', 'NULL']

错误：

Traceback (most recent call last):

    sample.HistoryInsert()
  File "/home/dobbs/PycharmProjects/autoshun/sqlobjects.py", line 95, in HistoryInsert
    self.cur.execute(insert_query, values)

    query = self.mogrify(query, args)

    query = query % self._escape_args(args, conn)

Answer 1

继续并省略 id 字段。 MySQL 会知道该怎么做：

    insert_query = (
        "INSERT INTO `autoshun`.`shunhistory` "
        "(attackerip, victimip, shunlen, shuncount, shunreason, shunepoch, shundatetime, shunerrorbool, "
        "shunerror, paloaddedepoch, paloremovedepoch) "
        "VALUES "
        "(%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s );"
    )

    values = [self.attackerip, self.victimip, self.shunlen, self.shuncount, self.shunreason, self.shunepoch,
              self.shundatetime, self.shunerrorbool, self.shunerror, self.paloaddedepoch, self.paloremovedepoch]

因为您的查询有一个 NULL，而您正试图在没有 None.

参数的情况下传入 None
