HTTP代理使用样例

本文档包含编程请求http代理服务器的代码样例，供开发者参考。

样例使用说明

  1. 代码样例不能直接运行，因为代码中的订单号1834987042xxxxxx、代理IP和端口号117.69.63.102:43787、
     用户名username、密码password都是虚构的，请替换成您自己的信息。
  2. 代码样例正常运行所需的运行环境和注意事项在样例末尾均有说明，使用前请仔细阅读。
  3. 使用代码样例过程中遇到问题请联系售后客服，我们会为您提供技术支持。

注意事项

以下样例均为基础案例,运行是并不能保证能成功爬取到目标网站,目标网站通常具有反爬重机制,如跳转时需要输入验证码的页面
建议您在开发过程中基于基础样例进行如下改进

  1. 添加IP池管理
  2. 合理控制对目标网站的请求频率，建议对同一网站1个代理IP每秒请求不超过1次；
  3. 发出的http请求尽可能带上完整的header信息。

Python3

request

request (推荐)

使用提示

  1. 基于requests的代码样例支持访问http,https网页，推荐使用
  2. requests不是python原生库，需要安装才能使用: pip install requests

如需使用用户名密码+无界面方式认证代理,请使用使用 Selenium + PhantomJS

PhantomJS

用户名密码认证+无界面模式

使用提示

  1. 基于用户名密码+无界面方式使用 Selenium + PhantomJS认证代理
  2. 运行环境要求python⅔ + selenium + PhantomJS + Windows/Linux/macOS
  3. 点此下载PhantomJS（推荐使用2.1.1版）
  4. ${executable_path}：您本机PhantomJS驱动存放路径，如："C:\phantomjs-2.1.1-windows\bin\phantomjs.exe"

Python-Scrapy

使用提示

  1. http/https网页均可适用
  2. scrapy不是python原生库，需要安装才能使用: pip install scrapy
