node.js 调用c动态库，选用哪种方法好

2种方法。 一种编程的时候，直接include库文件. 编好的程序使用时为 *** 作系统直接调用。 二种为编程的时候，使用LoadLibrary,FreeLibrary,GetProcAddress来动态装载程序。则编好的程序使用库文件时，是程序自己主动载入。

For this assignment, and web development in general you will need to exercise your "google-fu", your skill in using a search engine to find answers to problems.

You do not need to do much backend coding at all for Module 1. app.js should just contain hard coded response values.

You will need to add functionality to app.js, index.html, index.js and, if you wish, style.css.

We are using NodeJS runtime to create a simple web server

We are using ExpressJS framework for our API and routing: https://expressjs.com/en/starter/hello-world.html

An Application Programming Interface (API) is essentially just an interface, we're using to serve our set of routes for the client browser JavaScript to interact using HTTP protocol to access Backend functionality.

We're creating a RESTful API: https://restfulapi.net/

HTTP Methods to consider:

In Express it's very simple to create a single "route". A route is just an endpoint you can access from your JavaScript

Here's an example in app.js:

More information here: https://expressjs.com/en/guide/routing.html

Request contains the data sent from the Frontend JavaScript

Response is what we send back to the client after they make an AJAX call

Note that res.send() should take a JavaScript Native Object, NOT a string with JSON in it

You can parse a JSON string into a native object:

The stub provides app.get() and app.port() routes for handling .ged file upload/doanload requests from the browser. All .ged files must be placed ino the uploads/ directory.
