如何在node.js(express.js)中获取浏览器语言？

npm install express

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

app.get('/', (req, res) => {
  const browserLanguage = req.headers['accept-language'];
  res.send(`浏览器语言：${browserLanguage}`);
});

app.listen(3000, () => {
  console.log('服务器已启动，监听3000端口');
});

node app.js

npm install accept-language-parser

const express = require('express');
const acceptLanguageParser = require('accept-language-parser');
const app = express();

app.get('/', (req, res) => {
  const browserLanguages = acceptLanguageParser.parse(req.headers['accept-language']);
  res.send(`浏览器语言：${JSON.stringify(browserLanguages, null, 2)}`);
});

app.listen(3000, () => {
  console.log('服务器已启动，监听3000端口');
});
