ChatGPT实战100例 – (04) 自动化爬虫
一、需求与思路
需求:解析网页元素太复杂,要让他自动解析
操作步骤:
- ChatGPT编写相关脚本
- python跑起来
需要的前置技能:听说过python爬虫库requests和bs4
没听过?简单:
- requests是一个Python HTTP请求库,用于获取网页数据。
- bs4是BeautifulSoup的缩写,是一个HTML/XML解析库,用于从网页数据中提取信息。
二、油猴子脚本
问题:
写一段python的bs4库解析,试着从这段html中解析如下结构化信息:
图标 类别 标题 网址 简介
并使用json表示,使用英文字段
<div class="url-card io-px-2 col-6 col-2a col-sm-2a col-md-2a col-lg-3a col-xl-5a col-xxl-6a "> <div class="url-body default "> <a href="/sites/4661.html?menu-id=2331&mininav-id=4543" target="\_blank" data-id="4661" data-url="https://murf.ai" class="card no-c mb-4 site-4661" title="Murf AI"> <div class="card-body url-content d-flex align-items-center"> <div class="url-img rounded-circle mr-2 d-flex align-items-center justify-content-center"> <img class="lazy unfancybox loaded" src="https://api.iowen.cn/favicon/murf.ai.png" data-src="https://api.iowen.cn/favicon/murf.ai.png" height="auto" alt="Murf AI" data-was-processed="true"> </div> <div class="url-info flex-fill"> <div class="text-sm overflowClip\_1"> <strong>Murf AI</strong> </div> <p class="overflowClip\_1 m-0 text-muted text-xs"> AI语音生成器在20种语言。120+逼真的文本到语音的声音,创造完美的AI画外音。轻松地从文字转换为语音。</p> </div> </div> </a> <a href="/go/?url=aHR0cHM6Ly9tdXJmLmFpLw%3D%3D" target="\_blank" rel="external nofollow noopener" title="" class="togo text-center text-muted is-views" data-id="4661" data-toggle="tooltip" data-placement="right" data-original-title="直达"><i class="iconfont icon-goto"></i></a> </div></div>
回答:
英文的
Here’s a Python code to extract the structured information from the HTML and represent it in JSON format:
import requestsfrom bs4 import BeautifulSoupimport jsonurl = "页面的url"response = requests.get(url)soup = BeautifulSoup(response.content, "html.parser")results = []for card in soup.find_all("div", class_="url-card"): icon = card.find("img")["data-src"] category = card.find("a", class_="card")["data-id"] title = card.find("strong").text website = card.find("a", class_="card")["data-url"] description = card.find("p", class_="overflowClip_1").text result = { "icon": icon, "category": category, "title": title, "website": website, "description": description } results.append(result)json_result = json.dumps(results)print(json_result)
This code extracts the icon, category, title, website, and description of each tool listed on the page and saves them in a list of dictionaries. Finally, it converts the list to a JSON string and prints it.
三、部署
pip install requestspip install bs4
脚本跑起来就好
四、总结
关键是给他html,给目标,剩下就是喝枸杞红茶和等待了。
