利用Python抢购脚本，低价货源！

因为一开始只是想爬取电脑办公类目下的商品，所以没有定义函数。(好吧 我承认自己没有一个好的python编写习惯)

最后才写的for，看起来怪怪的。

一次差不多2900个商品链接。

Python代码：

import requests

import json

import re

import csv

dnbg = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=29&_=1495211171059‘ #电脑办公

shdq= ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=19&_=1495250002658‘ #生活电器

sjtx = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=30&_=1495251020781‘ #手机通讯

djd = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=25&_=1495251044176‘ #大家电

znsm = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=31&_=1495251057993‘ #智能数码

yljs = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=45&_=1495251084828‘ # 饮料酒水

jjjz = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=37&_=1495251148047‘ #家具家装

mytz = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=43&_=1495251122767‘ #母婴童装

spsx = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=44&_=1495250603966‘ #食品生鲜

ghjq = ‘https://ai.jd.com/index_new?app=Seckill&action=pcSeckillCategoryGoods&callback=pcSeckillCategoryGoods&id=32&_=1495251170952‘ #个护家清

def jdmiaosha(url): #开始只是想爬去电脑办公的 函数是后来加上去的

resp= requests.get(url).text

#print(resp)

resp = re.findall(r‘\((.+)\)‘,resp)[0] #提取纯json代码 不然解析会出错

#print(resp)

s = json.loads(resp)

with open("jd.csv","a",newline="") as datacsv:

csvwriter = csv.writer(datacsv,dialect = ("excel"))

csvwriter.writerow(["商品","价格","销售状态","链接"])

datacsv.close

for i in s[‘goodsList‘]:

sales_url = "https://item.jd.com/"+str(i[‘wareId‘])+".html"

if ‘soldRate‘ in i.keys():

sales_status = str(i[‘soldRate‘])+"%" # 区别是否开抢 确定销售状态

else:

if not i[‘startTimeContent‘]:

sales_status = "---"

else:

sales_status = i[‘startTimeContent‘]

print(‘商品：{0}\t价格：{1}\t销售状态:{2}\t链接:{3}.‘.format(i[‘wname‘],i[‘miaoShaPrice‘],sales_status,sales_url)) #格式化输出

with open("jd.csv","a",newline="") as datacsv: #写入到csv文件

csvwriter = csv.writer(datacsv,dialect = ("excel"))

csvwriter.writerow([i[‘wname‘],i[‘miaoShaPrice‘],sales_status,sales_url])

for url in [dnbg,shdq,sjtx,djd,znsm,yljs,jjjz,mytz,spsx,ghjq]:

jdmiaosha(url)

大功告成，利用Python秒杀京东抢购商品，自己也可以做微商，一手低价货源。
