【小程序】小程序request请求参数加盐并采用sha1+md5加密

最近遇到一个问题:在wx.request请求时传递的参数采用sha1+md5的方式加密:

之前在vue项目中可以下载utility插件进行方法调用↓

const utils = require("utility");

utils.sha1(utils.md5(xxxx + "盐"))

但是在小程序中我好像没有找到类似可用的插件,于是找到了民间大神的写法:
建议一个静态站utils,创建sha1和md5文件
【小程序】小程序request请求参数加盐并采用sha1+md5加密

我是在skey里用到了 把代码贴给你们:
【小程序】小程序request请求参数加盐并采用sha1+md5加密
这是一串先被md5加密再加盐被sha1的加密data,这个jiami方法就是进行这个操作的

这个skey只是我这个需求的一种写法(先md5后sha1),你们可以根据自己的需求来
skey:

let md5 = require('./md5')

let sha1 = require('./sha1')

export function jiami (data) {

for(let index in data){

data[index] = String(data[index])

}

var str = JSON.stringify(data);

str += '盐';

str = md5.hex_md5(str);

str += '盐'

str = sha1.hex_sha1(str);

return str;

}

// export const jiami = jiami;
