使用Node.js在Rasberry Pi中将wifi凭据更新为wpa_supplicant.conf

sudo apt update
sudo apt install nodejs npm

const fs = require('fs');
const path = require('path');

// 新的Wi-Fi凭据
const newCredentials = {
  ssid: 'YourNewSSID',
  psk: 'YourNewPassword'
};

// wpa_supplicant.conf文件路径
const configFilePath = '/etc/wpa_supplicant/wpa_supplicant.conf';

// 读取现有配置文件
fs.readFile(configFilePath, 'utf8', (err, data) => {
  if (err) {
    console.error('Error reading file:', err);
    return;
  }

  // 更新凭据
  const updatedData = data.replace(
    /network=\{[\s\S]*?\}/g,
    `network={
      ssid="${newCredentials.ssid}"
      psk="${newCredentials.psk}"
    }`
  );

  // 写回文件
  fs.writeFile(configFilePath, updatedData, 'utf8', (err) => {
    if (err) {
      console.error('Error writing file:', err);
      return;
    }
    console.log('Wi-Fi credentials updated successfully.');
  });
});

sudo node update_wifi.js
