如何在Node.js中encode一个字符串呢?是否也像在PHP中使用base64_encode()一样简单? 在Node.js中有许多encoding字符串的方法,而不用像在JavaScript中那样定义各种不同的全局函数.下面是如何在Node.js中将一个普通字符串encode成Base64格式的代码: var b = new Buffer('JavaScript'); var s = b.toString('base64'); // SmF2YVNjcmlwdA== 下面是decode b
普通字符串 编码解码: var b = new Buffer('JavaScript'); var s = b.toString('base64'); // SmF2YVNjcmlwdA== var b = new Buffer('SmF2YVNjcmlwdA==', 'base64') var s = b.toString(); // JavaScript 编码解码并转成hex var b = new Buffer('SmF2YVNjcmlwdA==', 'base64') var s = b

String转int.float.double.byte[].bitmap Int i = Integer.parseInt(str); Float f = Float.parseFloat(str); Double d = Double.parseDouble(str); //将16进制字符串转byte数组 public static byte[] hexStringToByte(String str) { if(str == null || str.trim().equals(""

上一篇写了通过webdriver在浏览器环境下异步调用js代码. 今天进入正题. 事实上有了executeAsyncScript,一切就呼之欲出了. 直接上代码: var compareImage=function(){ return function(){ eval(arguments[0]); var canvasBase64=arguments[1]; var expectBase64str=arguments[2]; var callback=arguments[ arguments.l
