Node.js使用原生创建服务及实现静态资源托管/接口请求

1.环境

　　采用12.13.x版本

2.创建server.js

　　文件内容如下：

let http = require("http");
let fs = require("fs");

let server = http.createServer((req, res) => {
    if (req.url.indexOf("/api") !== -1) {
        console.log("这是接口地址")
    } else {
        let path = req.url === "/" ? "/index.html" : req.url;
        try {
            let data = fs.readFileSync("./www" + path);
            res.write(data);
            res.end();
        } catch (e) {
            let error = fs.readFileSync("./www/error.html");
            res.write(error);
            res.end();
        }
    }
});
server.listen(80, () => {
    console.log("server is running")
})
