CMD控制屏幕亮度

一开始用brightness，dev下可用，打包后执行报错，找了很多文章都没办法解决。后来想到执行CMD命令去设置( 如何在 Windows 中使用命令行调整屏幕亮度 )。测试打包后正常，无需管理员权限。

1. 引入exec

   const { exec } = require('child_process')
   

2. 获取屏幕亮度

   function getScreenBrightness() {return new Promise<number>((resolve,reject) => {exec('powershell.exe "(Get-WmiObject -Namespace root\\WMI -Class WmiMonitorBrightness).CurrentBrightness"', (error: Error | null, stdout: any) => {if (error) {console.log('get screen brightness error')reject(0)} else {resolve(stdout.trim())}})})
   }
   

3. 设置屏幕亮度（0~100）

   function setScreenBrightness(brightness: number): Promise<void> {return new Promise((resolve) => {const command = `WMIC /NAMESPACE:\\\\root\\wmi PATH WmiMonitorBrightnessMethods WHERE "Active=TRUE" CALL WmiSetBrightness Brightness=${brightness} Timeout=0`exec(command, (error: Error | null) => {if (error) {console.error(`Error: ${error.message}`)}resolve()})})
   }
