如何用golang搜索抓取淘宝商品,第1张

您好

golang搜索抓取淘宝商品需要进行数据的引入,一般是if engine.ToString(val) != "hello" { t.FailNow() } } 传递进去的参数的生命周期是php控制的,在request shutdown的时候内存会被释放。 PHP 回调 Golang type greeting!

可以通过requests库re库进行淘宝商品爬虫爬取

import requests

import re

def getHTMLText(url):

try:

r= requests.get(url,timeout=30)

r.raise_for_status()

r.encoding = r.apparent_encoding

return r.text

except:

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 = eval(tlt[i].split(':')[1])

ilt.append([price,title])

except:

print("F")

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 = count +1

print(tplt.format(count,g[0],g[1]))

def main():

goods = '书包'

depth = 2

start_url = "https://s.taobao.com/search?q="+ goods

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()

这段代码在过去是可以爬取淘宝商品信息,但是因为淘宝的反扒技术升级,便不能让你大摇大摆地进出自如了。

此外也可以借助采集实现采集
