小程序如何使用md5

小程序如何使用md5

1、下载MD5源文件(JS);

2、在小程序模块中使用require引入外部模块;也可以在app.js中直接全局引入md5.js文件。

因为源md5.js中没有对模块进行输出,如果使用require需要export,所以在md5.js中需要加入以下代码:

module.exports =  {  hexMD5: hex_md5, //需要输出的加密算法,我这边只写了我需要得两种  b64Md5: b64_md5,}

在js文件中使用require引入md5:

推荐学习:小程序开发

const md5 = require('../../assets/js/md5/md5.js');

使用:

let b64 = md5.b64Md5(code); //code需要加密的数据

下面是我的文件结构:
