1.via bat:
const { exec, spawn } = require('node:child_process');

exec('my.bat', (err, stdout, stderr) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log(stdout);
});

// Script with spaces in the filename:
const bat = spawn('"my script.cmd"', ['a', 'b'], { shell: true });
// or:
exec('"my script.cmd" a b', (err, stdout, stderr) => {
  // ...
});

2.via powershell:
const { execFileSync } = require('node:child_process');

try {
  const stdout = execFileSync('powershell', ['123'], {
    // Capture stdout and stderr from child process. Overrides the
    // default behavior of streaming child stderr to the parent stderr
    stdio: 'pipe',

    // Use utf8 encoding for stdio pipes
    encoding: 'utf8',
  });

  console.log(stdout);
} catch (err) {
  if (err.code) {
    // Spawning child process failed
    console.error(err.code);
  } else {
    // Child was spawned but exited with non-zero exit code
    // Error contains any stdout and stderr from the child
    const { stdout, stderr } = err;

    console.error({ stdout, stderr });
  }
}
3.via python:
const { execFileSync } = require('node:child_process');

try {
  const stdout = execFileSync('python.exe', ['arg'], {
    // Capture stdout and stderr from child process. Overrides the
    // default behavior of streaming child stderr to the parent stderr
    stdio: 'pipe',

    // Use utf8 encoding for stdio pipes
    encoding: 'utf8',
  });

  console.log(stdout);
} catch (err) {
  if (err.code) {
    // Spawning child process failed
    console.error(err.code);
  } else {
    // Child was spawned but exited with non-zero exit code
    // Error contains any stdout and stderr from the child
    const { stdout, stderr } = err;

    console.error({ stdout, stderr });
  }
}
4.via 文件:

const { exec} = require('node:child_process') 
const os = require("os");
const iconv = require('iconv-lite');
const encoding = os.platform() == 'win32' ? 'cp936' : 'utf-8';
const binaryEncoding = 'binary';
// 执行命令并获取结果
const { argv } = require('node:process');



argv.forEach((args) => {
    const runExec = (powershell) => {   
        return new Promise((resolve, reject) => {
            exec(powershell, { encoding: binaryEncoding }, function(error, stdout, stderr) {
                if (error) {
                    reject(iconv.decode(new Buffer.from(error.message, binaryEncoding), encoding));
                } else {
                    resolve(iconv.decode(new Buffer.from(stdout, binaryEncoding), encoding));
                }
            });
        })
    }
    var url = process.argv.slice(2);
    
    runExec(`"POWERSHELL" C:\\Users\\34683\\dre\\dre\\crawl1.ps1 ${url}`).then(res => {
    
    
    
    const jsdom = require("jsdom");
    const dom = new jsdom.JSDOM(res)
    console.log(dom.window.document.title)
    }).catch(err => {
        console.log('执行失败', err);
    })

});




PS.
.如果不想使用绝对路径,可以使用path 来定义相对路径
const { execFileSync } = require('node:child_process');
const path = require('node:path');
const os = require("os");
const iconv = require('iconv-lite');

// 设置编码
const encoding = os.platform() == 'win32' ? 'cp936' : 'utf-8';

// 获取当前路径
const currentDir = process.cwd();

// 构建 PowerShell 脚本路径
const scriptPath = path.join(currentDir, 'crawl1.ps1');

try {
    // 使用 execFileSync 运行 PowerShell 脚本
    const stdout = execFileSync('powershell', [scriptPath], {
        // 设置同步执行
        stdio: 'pipe',
        encoding: 'utf8',
    });

    console.log(stdout);
} catch (err) {
    if (err.code) {
        // 子进程执行失败
        console.error(err.code);
    } else {
        // 子进程执行成功但出现错误
        const { stdout, stderr } = err;
        console.error({ stdout, stderr });
    }
}


.windows 中空格可能导致路径不完整而出错可以通过加入双引号而解决
:

const { exec } = require('node:child_process');
const path = require('node:path');
const os = require("os");
const iconv = require('iconv-lite');

// 设置编码
const encoding = os.platform() == 'win32' ? 'cp936' : 'utf-8';

// 获取当前路径
const currentDir = process.cwd();

// 构建 PowerShell 脚本路径，并确保路径包含空格时被正确处理
const scriptPath = path.join(currentDir, 'crawl1.ps1');

// 异步执行 PowerShell 脚本，路径用双引号包裹
exec(`powershell -ExecutionPolicy Bypass -File "${scriptPath}"`, { encoding: 'binary' }, (error, stdout, stderr) => {
    if (error) {
        console.error(iconv.decode(Buffer.from(error.message, 'binary'), encoding));
    } else {
        console.log(iconv.decode(Buffer.from(stdout, 'binary'), encoding));
    }

    if (stderr) {
        console.error(iconv.decode(Buffer.from(stderr, 'binary'), encoding));
    }
});
