1、图片转base64

var fs = require("fs");

var imageBuf = fs.readFileSync("D:\\Documents\\Desktop\\logo.gif");

console.log(imageBuf.toString("base64"));

 

2、转base64

var a= newBuffer('key1=value1&key2=value2').toString('base64');

 

undefined> a'a2V5MT12YWx1ZTEma2V5Mj12YWx1ZTI='>

newBuffer(a,'base64').toString()

 

'key1=value1&key2=value2'
