python爬虫如何设置代理ip

# 用到的库

import requests

# 写入获取到的ip地址到proxy

proxy = {

    'https':'221.178.232.130:8080'

}

# 用百度检测ip代理是否成功

url = 'https://www.baidu.com/s?'

# 请求网页传的参数

params={

    'wd':'ip地址'

}

# 请求头

headers = {

    'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36'

}

# 发送get请求

response = requests.get(url=url,headers=headers,params=params,proxies=proxy)

# 获取返回页面保存到本地，便于查看

with open('ip.html','w',encoding='utf-8') as f:

    f.write(response.text)
