Question

我有以下函数应该批量插入IPv6 IP列表

def insertToDb(ipList):
  print("OK")
  try:
    conn = psycopg2.connect("dbname='mydb' user='myuser' host='hanno.db.elephantsql.com' password='mypass'")
  except:
    print("I am unable to connect to the database")
  cur = conn.cursor()
  try:
    cur.executemany("INSERT INTO ip (ip) VALUES(%s)", ipList)
    conn.commit()
  except Exception as e: print(e)
  print("Inserted!")

我收到以下消息

并非在字符串格式化期间转换所有参数

需要正确的格式是什么？

Answer 1

使用Logger logger = LoggerFactory.getLogger(HttpUtil.class); HttpLoggingInterceptor logging = new HttpLoggingInterceptor((msg) -> { logger.debug(msg); }); logging.setLevel(Level.BODY); client.addNetworkInterceptor(logging);，您可能只需要将executemany转换为如下所示的元组列表：

ipList

或者您也可以将列表的构建方式更改为：

params = [(ip,) for ip in iplist]
cur.executemany("INSERT INTO ip (ip) VALUES(%s)", params)

cur.executemany并非在字符串格式化期间转换所有参数
