MD5

安装 md5-node

npm install md5-node

测试

var md5 = require('md5-node');
console.log(md5('123456'));//e10adc3949ba59abbe56e057f20f883e

字典序排序

比如b=1,a=2,c=3, 排完后是a=2,b=1,c=3

let dict = {a: 3, b:1, c:2};
for (let key of Object.keys(dict).sort()) {
  console.log(key, dict[key]);
}

获取时间戳(毫秒，秒)

/**
 * 获取当前时间戳(毫秒)
 */
function getNowMilliSecond(){
	return Math.floor(Date.now());
}
/**
 * 获取当前时间戳(秒)
 */
function getNowSceond(){
	return Math.floor(Date.now() / 1000);
}
 
//当前时间戳(毫秒)
console.log("curMilliSecond=%d",getNowMilliSecond());   //输出：curMilliSecond=1608090151913
//当前时间戳(秒)
console.log("curSecond=%d",getNowSceond());             //输出：curSecond=1608090151
