python爬虫Socks代理

requests请求网页(无用户认证)

session = requests.session()
session.proxies = {'http': 'socks5://127.0.0.1:9050',
                   'https': 'socks5://127.0.0.1:9050'}
resp = session.get('https://api.github.com', auth=('user', 'pass'))
print(resp.status_code)

requests请求网页（有用户认证）

http/https网页均可适用
运行环境要求：requests >= 2.10.0
socks支持是requests的额外特性，需要安装才能使用: pip install requests[socks]

import requests

# 要访问的目标网页
page_url = "http://dev.kdlapi.com/testproxy"

# 代理服务器 提示：生成api链接时代理类型请勾选socks4/socks5
proxy = "59.38.241.25:23916"

# 用户名和密码(私密代理/独享代理)
username = "myusername"
password = "mypassword"

proxies = {
    'http': 'socks5://%s:%s@%s' % (username, password, proxy),
    'https': 'socks5://%s:%s@%s' % (username, password, proxy),
    # 提示：如果希望在代理服务器上进行dns解析，把socks5替换成socks5h
}

headers = {
    "Accept-Encoding": "gzip",  # 使用gzip压缩传输数据让访问更快
}


r = requests.get(page_url, proxies=proxies, headers=headers)

print(r.status_code)  # 获取Response的返回码

if r.status_code == 200:
    print(r.text)  # 获取页面内容

selenium请求网页(无用户认证)

运行环境要求selenium + chrome + chromedriver
socks5代理网页均可适用
请先下载chromedriver并将chromedriver添加到环境变量中

from selenium import webdriver

# 代理服务器
proxy_ip_port = '42.49.11.109:21080'
proxy = 'socks5://' + proxy_ip_port

# 目标网页
page_url = "https://dev.kuaidaili.com/testproxy"

co = webdriver.ChromeOptions()
co.add_argument('--proxy-server=%s' % proxy) # 设置代理
co.add_argument('--headless')  # 无窗口模式, 可选

# 启动chrome
driver = webdriver.Chrome(chrome_options=co)

# 抓取网页
driver.get(page_url)

# 输出网页内容
print(driver.page_source)

# 退出chrome
driver.quit()

co.add_argument("--start-maximized")  # 最大化窗口, 不加可能报错
co.add_extension(proxyauth_plugin_path) # 添加扩展

# 启动chrome, 抓取网页
