使用javascript将Base64解码为十六进制字符串 [英] Decode Base64 to Hexadecimal string with javascript

问题描述

$ b 示例：

 
 
 code> var base64Value =oAAABTUAAg ==
  

需要转换方法

输出（解码数据（十六进制）） A0000005350002

是正确的，因为我可以使用此网站 http://tomeko.net/online_tools/base64.php ？lang = en

并在Base64字符串中输入 oAAABTUAAg == 并获得 A0000005350002

我试过了什么？

https://github.com/carlo/ jquery-base64

https://jsfiddle.net/gabrieleromanato/qaght/

我发现了很多问题

解决方案

atob（）然后charCodeAt（）会给你二进制& toString（16）会给你十六进制数据。

function base64toHEX（base64）{ var raw = atob（base64）; var HEX =''; for（i = 0; i

Needing to convert a Base64 string to Hexadecimal with javascript.

Example:

var base64Value = "oAAABTUAAg=="

Need conversion method

Output (Decoded data (hexadecimal)) A0000005350002

I know this is correct because I can use this website http://tomeko.net/online_tools/base64.php?lang=en

and punch in Base64 string of oAAABTUAAg== and get A0000005350002

What have I tried?

I have found a lot of questions

解决方案

atob() then charCodeAt() will give you binary & toString(16) will give you hex.

function base64toHEX(base64) {

  var raw = atob(base64);

  var HEX = '';

  for ( i = 0; i < raw.length; i++ ) {

    var _hex = raw.charCodeAt(i).toString(16)

    HEX += (_hex.length==2?_hex:'0'+_hex);

  }
  return HEX.toUpperCase();

}

console.log(base64toHEX("oAAABTUAAg=="));
