2.使用的时候用var api = require('../../utils/api.js')加载代码，然后使用api.SYNC_TABLE_URL 直接调用
3.调用方世和法也差不多。
1、下载MD5源文件(JS)2、在漏吵小程序模块中返脊侍使用require引入外部模块；也可以在index.html中直接全局引入md5.js文件。
因为源md5.js中没有队模块因为输出，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，我这边只野歼写了我需要得两种
b64Md5: b64_md5,
}
在js文件中使用require引入md5:
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：
md5.js 代码如下

用过 npm 的小伙伴肯定很熟悉 node_modules，但是「微信开发工具」是不认 node_modules 的 , 它认的是 miniprogram_npm；弊宴 而 miniprogram_npm 是通过 node_modules 转出来的， 它是通过「微信开发工具」的 “拦拦工具” ->“构建 npm” 生成出来的。
具体步骤如下：
1、 npm init
这里会产生 package.json 的配置文件
2、 npm install ** --p --s
安装需要的包，这里会产生 node_modules
3、「微信开发工具」走一遍 “工具” ->“构建 npm”
这里会产生 miniprogram_npm
4、「微信开发工具」的本地配置中 “使用 npm 模块” 勾上
5、使用包
引入的组件可以有第三方组件和 js 工具
1、 按照步骤安装库同时走一遍 “工具” ->“构建 npm”，产生\miniprogram_npm\weui-miniprogra
npm install weui-miniprogram --p --s
2、 在 app.wxss 引入全局样式
3、在需要使用的页面中引入控件和使用，
譬如 pages/index/index.json，然后就可以在 index.wxml
1、 按照步骤安装库同时走一租衡银遍 “工具” ->“构建 npm”，产生\miniprogram_npm\js-base64
npm install js-base64 --p --s
2、在 *.js 文件中用 require 或者 import 引入，然后使用
