Question

我想迭代并调用与＆＃34; os＆＃34;

相关联的所有成员函数

var os = require('os'); 
var keye = Object.keys(os);
keye.forEach(f => os.f());

{ endianness: [Function: getEndianness],
  hostname: [Function: getHostname],
  loadavg: [Function: getLoadAvg],
  uptime: [Function: getUptime],
  freemem: [Function: getFreeMem],
  totalmem: [Function: getTotalMem],

  type: [Function: getOSType],
  release: [Function: getOSRelease],

  platform: [Function],
  tmpdir: [Function],
  tmpDir: [Function],

你需要这样的东西：

Object.keys(os).forEach(function (key) {
    if (typeof os[key] === 'function') {
        console.log(key, os[key]());
    }
});
