Question

用代理池爬取数据正常爬取到，单单用一个代理爬取则全是广告

一个代理爬取

import urllib.request
url = 'https://www.baidu.com/s?wd=ip'
header = {
    'user-agent':' Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36 Edg/110.0.1587.50'
}

#代理IP
proxies = {
     'http':'111.225.153.46:8089'
}
request = urllib.request.Request(url=url,headers=header)

#handler处理器
handler = urllib.request.ProxyHandler(proxies)

opener = urllib.request.build_opener(handler)

respone = opener.open(request)

content  = respone.read().decode('utf-8')

with open(file='ipp.html',mode='w',encoding='utf-8') as fp:
    fp.write(content)

结果

代理池

import urllib.request
import random

url = 'https://cn.bing.com/search?q=ip'
header = {
    'user-agent':' Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36 Edg/110.0.1587.50'
}

#代理池
proxies_pool = [
    {'http':'211.97.2.196:9002'},
    {'http':'111.225.153.46:8089'}
]
request = urllib.request.Request(url=url,headers=header)

#从代理池里面随机抽取一个代理IP，我是选择跟上面一个代理IP一样的代理IP结果作为比较的
#即  'http':'111.225.153.46:8089'
proxies = random.choice(proxies_pool)

print(proxies)

handler = urllib.request.ProxyHandler(proxies)

opener = urllib.request.build_opener(handler)

respone = opener.open(request)

content = respone.read().decode('utf-8')

with open(file='ip_pool.html',mode='w',encoding='utf-8') as fp:
    fp.write(content)

结果

Answer 1

两次的引擎不一样？一个百度，一个必应。
我以前也做过类似的项目，百度反爬总是更猛，广告巨多
