?京東圖書評論有非常豐富的信息，這里面就包含了購買日期、書名、作者、好評、中評、差評等等。以購買日期為例，使用Python + Mysql的搭配進行實現，程序不大，才100行。相關的解釋我都在程序里加注了：

from selenium import webdriver
from bs4 import BeautifulSoup
import re
import win32com.client
import threading,time
import MySQLdb

def mydebug():
??? driver.quit()
??? exit(0)

def catchDate(s):
??? """頁面數據提取"""
??? soup = BeautifulSoup(s)
??? z = []
??? global nowtimes
???
??? m = soup.findAll("div",class_="date-buy")
??? for obj in m:
??????? try:
??????????? tmp = obj.find('br').contents
??????? except Exception, e:
??????????? continue
??????? if(tmp != ""):
??????????? z.append(tmp)
??????????? nowtimes += 1
??? return z

def getTimes(n,t):
??? """獲取當前進度"""
??? return "當前進度為：" + str(int(100*n/t)) + "%"
