arm下使用node.js

1.安装node

cd /usr/local/
  npm init -y
  npm config set registry https://registry.npmmirror.com
  npm install ffi-napi express cors

2.创建node.service

[Unit]  
Description=Service  
After=network.target  
  
[Service]  
Type=simple
WorkingDirectory=/usr/local/app  
ExecStart=/usr/bin/node /usr/local/app/server.js  
Restart=on-failure  
  
[Install]  
WantedBy=multi-user.target

3.编写server.js

const express = require('express');  
const ffi = require('ffi-napi');  
const cors = require('cors');
const { exec } = require('child_process');
const path = require('path');  
  
const app = express();  
const port = 3000;  
  
app.use(cors());

app.post('/api/test/:port', (req, res) => {  
    const port = req.params.port;  
    exec(`/usr/bin/test${port}`, (error, stdout, stderr) => {  
        if (error) {  
            console.error(`exec error: ${error}`);  
            return res.status(500).send('Internal Server Error');  
        }  
        res.send(stdout.trim());  
    });  
}); 



app.listen(port, () => {  
    console.log(`Node.js server listening at http://localhost:${port}`);  
});

4.编写调用的app.js

function test(port) {  
    const url = `/api/test/${port}`;  

    fetch(url, {  
        method: 'POST',  
        headers: {  
            'Content-Type': 'application/text', 
        },  

    })  
    .then(response => {  
        if (!response.ok) {  
            throw new Error('Network response was not ok ' + response.statusText);  
        }  
        return response.text(); 
    })  
    .then(data => {  
        console.log('Success:', data);  
    })  
    .catch(error => {  
        console.error('There was a problem with the fetch operation:', error);  
    });  
}  

5.编写shell脚本
