1:淘宝搜索地址:https://s.taobao.com/search?q=关键词
例:假如搜索书包,那么搜索地址便为 https://s.taobao.com/search?q=书包
2:翻页处理
可以发现淘宝每页44个商品,第i页url为 https://s.taobao.com/search?q=关键词&s=(i-1)*44

代码:
import requests
import re
def getHTMLText(url):
try:
r = requests.get(url)
r.raise_for_status()
r.encoding = r.apparent_encoding
#print(r.text)
return r.text;
except:
print("getHTMLText Error")
return ''
def parsePage(ilt, html):
try:
plt = re.findall(r'\"view_price\":\"[\d\.]*\"', html)
tlt = re.findall(r'\"raw_title\":\".*?\"', html)
for i in range(len(plt)):
price = eval(plt[i].split(':')[1])
title = tlt[i].split(':')[1]
ilt.append([price, title])
except:
print("parsePage Error")
def printGoodsList(ilt):
tplt = "{:4}\t{:8}\t{:16}"
print(tplt.format("序号", "价格", "商品名称"))
count = 0
for g in ilt:
count += 1
print(tplt.format(count, g[0], g[1]))
def main():
goods = 'iphone8'
start_url = 'https://s.taobao.com/search?q=' + goods
depth = 2
infoList = []
for i in range(depth):
try:
url = start_url + '&s=' + str(44*i)
html = getHTMLText(url)
parsePage(infoList, html)
except:
continue
printGoodsList(infoList)
main()
