http.request中如何让URL不转义特殊字符？

以下是官方文档中的示例代码，当请求参数area为1｜2｜3时，将自动转义为 http://hello.world/?area=1%7c2%7c3&type=1&key=4 请教如何能让其不转义？

const request = require('http').get;
const BASE_URL = ''http://hello.world/;
let area = '1|2|3', type = 1, key = 4;
request(`${BASE_URL}?area=${area}&type=${type}&key=${key}`, (res) => {
		const { statusCode } = res;
		let error;
		if (statusCode !== 200) {
			error = new Error(`Request Failed.\nStatus Code: ${statusCode}`);
		}
		if (error) {
			console.error(error.message);
			res.resume();
			return;
		}
		res.setEncoding('utf8');
		let rawData = '';
		res.on('data', (chunk) => { rawData += chunk; });
		res.on('end', () => {
			try {
				const parsedData = JSON.parse(rawData);
				console.log(parsedData);
				callback(error, parsedData);
			} catch (e) {
				console.error(e.message);
			}
		});
	}).on('error', (e) => {
		console.error(`Got error: ${e.message}`);
	});
