Node.js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")
 })
