使用ipip.net 免费ip库，实现自己的ip归属地查询

一，准备数据库，创建表，导入ip,事先国家省城市都是空的，后面查询写入

CREATE TABLE `comsumer10` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `c0` int(11) NOT NULL,
  `c1` int(11) DEFAULT NULL,
  `c2` double(64,2) NOT NULL,
  `ip` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `country` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `region` varchar(45) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `city` varchar(45) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2612 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

二，python安装 ipip-datx,pymysql模块，https://github.com/hrghrghg/datx-python

import datx,pymysql

def check_ip(ip):
    c = datx.City("17monipdb.datx")
    return c.find(ip)

def get_conn():
    conn = pymysql.connect(host='192.168.80.200', port=3306, user='root', passwd='123', db='django', charset='utf8')
    return conn

def query_all(cur, sql, args):
    cur.execute(sql, args)
    return cur.fetchall()

def ip_region():
    conn = get_conn()
    cur = conn.cursor()
    k=0
    sql_ip = 'select ip from comsumer10 where country is NULL limit 10;'
    results=query_all(cur=cur,sql=sql_ip,args=None)
    for i in results:
        res = check_ip(i[0])   #获取指定ip的归属地函数
        if res:
            sql_add = "update comsumer10 set country='"+res[0]+"',region='"+res[1]+"',city='"+res[2]+"' where ip='"+i[0]+"';"
            print(sql_add)
            cur.execute(sql_add)
            conn.commit()
        k = k+1
        print("===>:",k,"(",len(results),")")
    cur.close()
    conn.close()


if __name__ == '__main__':
    ip_region()
