本文主要介绍AIGC算法，readLink实现url识别pdf、html标题和内容

一、设计思路

• 识别url是pdf或者网页
• 网页处理逻辑，使用cheerio解析网页
• PDF处理逻辑，使用pdf-parse解析PDF文件
• 自定义的函数来提取标题和内容

二、可执行核心代码

const express = require("express");
const axios = require("axios");
const ytSearch = require("yt-search");
const cheerio = require("cheerio");const { PDFDocument } = require("pdf-lib");
const pdfParser = require("pdf-parse");const app = express();
const port = 3000;app.get("/read-link", async (req, res) => {const url = req.query.url;if (!url) {return res.status(400).send("URL is required");}try {const response = await axios.get(url, { responseType: "arraybuffer" });const contentType = response.headers["conte
