爬取的是整個(gè)筆趣閣的多個(gè)類型下的小說毅臊，分四層進(jìn)行爬取理茎，并存儲(chǔ)在mysql數(shù)據(jù)庫(kù)中，為網(wǎng)站提供數(shù)據(jù)源

代碼如下：

import urllib.request
# 數(shù)據(jù)庫(kù)的操作
import pymysql


class Sql(object):
    db = pymysql.connect(host="localhost", port=3306, db="novel", user="root", password="root", charset="utf8")

在mysql可視乎界面中新建了兩個(gè)表

  `id` int(20) NOT NULL AUTO_INCREMENT,
  `novelid` varchar(50) DEFAULT NULL,
