Node JS 文件本地网络互传

AlphaBrate Net Transfer Project

准备工作

灵感来源

Idea来源：电脑经常剪完视频想发到手机上，不过用xx网盘，x信，xQ传的很慢，还有时候网线出问题，还很麻烦 (那个就是写个这玩意更麻烦)
不过我还是选择做一下
这是AlphaBrate Team的项目，在这篇文章中，作为其成员，我将提供代码解说。
项目源码：https://github.com/alphabrate/nettransfer/

环境配置

Node JS

引用库

express
os
glob
electron

库用途

本地服务器：Express
获取文件列表：glob
GUI：Electron
ipv4：os

主文件

服务器：server.js
GUI：gui/gui.js

开始制作

服务器

server.js

引用库

const express = require("express"); // localhost server
const { networkInterfaces } = require('os'); // use to get user ipv4
const glob = require("glob"); // use to read path

获取ipv4地址 (本地ip)

用于向用户展示可连接的连接

const nets = networkInterfaces(); // return of network interface
const results = Object.create(null); // defind result
for (const name of Object.keys(nets)) { // geting ip
    for (const net of nets[name]) {
        // Skip over non-IPv4 and internal (i.e. 127.0.0.1) addresses
        // 'IPv4' is in Node <= 17, from 18 it's a number 4 or 6
        const familyV4Value = typeof net.family === 'string' ? 'IPv4' : 4
        if (net.family === familyV4Value && !net.internal) {
            if (!results[name]) {
                results[name] = [];
            }
            results[name].push(net.address);
        }
    }
}
const ipv4 = results["Wi-Fi"][0]; // ipv4 of user

ipv4将会是向用户展示的地址

生成连接和创建本地服务器

const app = express(); //
app.use(express.static("files")); // use folder: files as the static lib.
const pt = 1345; // port
const link = "http://" + ipv4 + ":" + pt; // generate the link
const file = __dirname + "\\files"; // generate the path that user put 

app.listen(pt,()=>{
    console.log("(C) AlphaBrate"); // Copyright info
    console.log("The Web is ready, please go to 'Net Transfer' tab."); //
}); // create server.

用户可以通过 ipv4:1345 (link) 访问

主页

我们需要一个便于用户操作的主页

基础代码
app.get("/",(req,res)=>{
    // Get file list
});
获取文件列表 Get file list
frs = []; // List of files
glob("files/*", function (er, files) {
    files.forEach(w=>{
        frs.push(w.split("files/")[1]);
    });
    // Render HTML
});
渲染HTML Render HTML

res.end() html，向其 <script> 内添加 frs 列表，让他自己渲染

res.end(`<!DOCTYPE html>
    <html>
    <head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <title>Net Transfer</title>
        #STYLE#
    </head>
    <body>
        <div class="body">
            <h1>#SVG#</h1>
                <div style="display:flex;flex-direction:column;align-items:center;font-size:24px;" id="eta"></div>
        </div>
        <script>
                const files = ${JSON.stringify(frs)};
                files.forEach(w=>{
                    document.getElementById("eta").innerHTML += "<a href=" + w + ">" + w + "</a>";
                });
        </script>
    </body>
    </html>`)

#SVG# 被省略 (SVG图标)
#STYLE# 被省略 (CSS Style)

const files = ${JSON.stringify(frs)}; 将原本在server.js的变量：frs 套入了向用户展示的html的<script>中，<script> 对 files 的每个元素执行一次向 #eta 加上一个<a>

生成<a>的规则：
由于我们使用了 app.use(express.static("files"));，所有被请求的静态文件都会在/files/中寻找，所以我们只需要将用户定向到 /:file 就行了

GUI 页面制作

由于无法在 GUI 中在获取一次文件列表 (或比较麻烦)
我们选择用 server.js 将 GUI 页面制作出来后再用 electron 提供本地窗口

这里的代码和上个部分很相似

app.get("/app/gui",(req,res)=>{
    frs = [];
    glob("files/*", function (er, files) {
        files.forEach(w=>{
            frs.push(w.split("files/")[1]);
        });
        res.end(`<!DOCTYPE html>

    });

服务器部分完成

server.js 部分完成，我们大部分工作也完成了
看看server.js完成效果

不要忘记添加文件到/files里面哦

直接将页面重定向到server.js开设的/app/gui里去

GUI 部分完成

gui.js 部分完成，项目接近尾声了
看看gui.js完成效果

/gui $< npm test

> npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.

> > guiofnettransfer@1.0.0 test

GUI

编译

最后，我们只需要将其编译使其脱离Node JS 环境也能正常运行就行了

这是我们写的 Compile Workflow，可以参考一下

编译需要用到 pkg

1. Compile server.js
    $root> pkg server.js
    a. Change name to server.exe
    b. put the it to the compile version folder (compile/x.x.x/*)
2. Compile gui.js
    $root/gui> npm run make
    a. put all file of compiled folder to the compile version folder (compile/x.x.x/)
    b. change guiofnettransfer.exe to gui.exe
3. Compile main.bat
    a. change name to main.exe
