A brief discussion on the solution to Chinese garbled characters in node

'use strict';
const http = require("http");
let count = 0;
const server = http.createServer((req, res) => {
    res.write(`这是第${count++}个访问的`);
    res.end();
});
server.listen(2080, error => {
    if (error)
        throw error;
    console.log("启动成功")
});

后来查询资料，原来加一个头部代码就行：
设置 res.writeHead(200, {'Content-Type': 'text/html; charset=utf-8'});

'use strict';
const http = require("http");
let count = 0;
const server = http.createServer((req, res) => {
    res.writeHead(200, {'Content-Type': 'text/html; charset=utf-8'});
    res.write(`这是第${count++}个访问的`);
    res.end();
});
server.listen(2080, error => {
    if (error)
        throw error;
    console.log("启动成功")
});
