↑ 关注 + 星标 ，每天学Python新技能 后台回复【 大礼包 】送你Python自学大礼 导读： 这篇文章利用简单的Python爬虫、邮件发送以及定时任务实现了每天定时发送睡前小故事的功能，是一篇步骤详尽的文章。 最近，某可爱要求我忙完之后给她每晚睡前讲讲小故事，我想了下，网络上应该有各种资源，小故事也都能搜得到，但是数量比较少，而且格式不够统一，提取比较困难。转念一想，面向儿童的睡前故事可能也比较适用，于是我准备从儿童睡前故事中取材，搜索之后发现有一个适合提取睡前故事的网址： tom61.com/ertongwenxue/ 一共有700则小故事，嗯，一天一则数量可以满足，html格式也比较统一，就决定是它了！ 查看网页源代码， ctrl+F 输入查询关键字幸福王国，定位到相关信息： 发现其故事链接包含在 dl 标签中的a标签中的 href 属性， /ertongwenxue/shuiqiangushi/2018-02-25/106432.html 点击后得到完整网址 tom61.com/ertongwenxue/ 接下来要做的就是提取出该链接： 1. 模拟浏览器访问网页，利用requests库请求访问 代码实现： def getHTMLText(url,headers): try: r=requests.get(url,headers=headers,timeout=30)

python学习之python爬虫原理

今天我们要向大家详细解说python爬虫原理，什么是python爬虫，python爬虫工作的基本流程是什么等内容，希望对这正在进行python爬虫学习的同学有所帮助! 前言 简单来说互联网是由一个个站点和网络设备组成的大网，我们通过浏览器访问站点，站点把HTML、JS、CSS代码返回给浏览器，这些代码经过浏览器解析、渲染，将丰富多彩的网页呈现我们眼前; 一、爬虫是什么? 如果我们把互联网比作一张大的蜘蛛网，数据便是存放于蜘蛛网的各个节点，而爬虫就是一只小蜘蛛， 沿着网络抓取自己的猎物(数据)爬虫指的是：向网站发起请求，获取资源后分析并提取有用数据的程序; 从技术层面来说就是 通过程序模拟浏览器请求站点的行为，把站点返回的HTML代码/JSON数据/二进制数据(图片、视频) 爬到本地，进而提取自己需要的数据，存放起来使用; 二、爬虫的基本流程： 用户获取网络数据的方式： 方式1：浏览器提交请求--->下载网页代码--->解析成页面 方式2：模拟浏览器发送请求(获取网页代码)->提取有用的数据->存放于数据库或文件中 爬虫要做的就是方式2; 1、发起请求 使用http库向目标站点发起请求，即发送一个Request Request包含：请求头、请求体等 Request模块缺陷：不能执行JS 和CSS 代码 2、获取响应内容 如果服务器能正常响应，则会得到一个Response
