node.js - 如何利用nodejs进行前后端的数据传递？

Question

在html文件中引入的js代码里使用ajax请求向服务器端发送数据请求，将这些数据写入文件，再次读取文件时，如何将读取到的文件数据重新传递出来？

Answer 1

The front end sends a ajax request. According to the request method get,post, you can use the Route module express
or the route.post() method of route.get() . I have a small demo here for reference. Demo

Answer 2

Have you not graduated from elementary school? Or is it from a training institution? Please see the nodejs documentation
