用于获取http的Javascript变量 [英] Javascript variables for Get http

问题描述

我正在学习JavaScript，并且想做与PHP $_GET[Var] = $foo;类似的JavaScript我正在为项目编码基本的CDN类型服务器， 另外，我该如何提供要使用JavaScript下载的文件?计划是在NodeJS节点内运行此代码.抱歉，如果我不好解释，我会很糟糕.

I am learning JavaScript and would like to do the JavaScript equivalent of PHP's $_GET[Var] = $foo; I am coding a basic CDN type server for a project, also, how can I serve a file for download with JavaScript? The plan is to run this code inside a NodeJS node. Sorry if I explained this badly, I am terrible at explaining things.

推荐答案

要从Node.js应用提供现有文件，请在express和express.static之间使用:

To serve existing files from your Node.js app, use express with express.static: http://expressjs.com/en/starter/static-files.html

以下示例使用ECMAScript 2015元素，并假定Node.js 4或5的静态文件存储在public目录中:

Example below uses ECMAScript 2015 elements and assumes Node.js 4 or 5 with static files stored in public directory:

const http = require('http'); 
const express = require('express');

const app = express();
app.use(express.static('public'));

const server = http.createServer(app).listen(8080, serverCallback);

function serverCallback() {
  const host = server.address().address;
  const port = server.address().port;
  console.log(`Server listening on ${host}:${port}`);
}
