获取与url一起提供的值

function getURLParameter(name) {
  name = name.replace(/[\[\]]/g, "\\$&");
  var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
      results = regex.exec(window.location.href);
  if (!results) return null;
  if (!results[2]) return '';
  return decodeURIComponent(results[2].replace(/\+/g, " "));
}

// 示例用法
var queryValue = getURLParameter('query');
var pageValue = getURLParameter('page');
console.log(queryValue);  // 输出 "cloud computing"
console.log(pageValue);  // 输出 "1"

const express = require('express');
const app = express();

app.get('/search', (req, res) => {
  const queryValue = req.query.query;
  const pageValue = req.query.page;
  res.send(`Query: ${queryValue}, Page: ${pageValue}`);
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
