rsa加解密（兼容微信小程序环境）

1、安装

npm i wxmp-rsa -S

2、创建一个js文件作为之后可复用的工具库，内容如下：

import { JSEncrypt } from 'wxmp-rsa'
// 定义公钥  这里要改为你自己的公钥
const publicKey = `
  -----BEGIN PUBLIC KEY-----
  MIGeMA0GCSqGSIb3DQEBAQUAA4GMADCBiAKBgFnWSUwsmGawhMJ30z6y5li2jcf1m7rPMZcwZOS3To8bk3OBaMGhVEc1F8GtJBbc1rn/HCLNL9zrCy21EefJON8tRFcYHnpseZSzh+349lIhS+MFw9x4JUddwSPDyxwha929cKzMuVoftu3CJ+kqDBVvxLk7iDBzUMqW3Kgehk2TAgMBAAE=
  -----END PUBLIC KEY-----
`
// 定义私钥  这里要改为你自己的私钥
const privateKey = `
-----BEGIN RSA PRIVATE KEY-----

`
const myEncrypt = new JSEncrypt()
myEncrypt.setPublicKey(publicKey)
myEncrypt.setPrivateKey(privateKey)
class rsaCode{
  encryptLong(data){//加密
    let datajson;
    if(typeof data !=="string"){
      datajson=JSON.stringify(data)
    }else{
      datajson=data
    }
    
    const cryptStr = myEncrypt.encryptLong(datajson)// 对需要加密的数据进行加密
    return cryptStr
  }
  decryptLong(cryptStr){//解密
    const originalStr = myEncrypt.decryptLong(cryptStr)
    return originalStr;
  }
}
export let rsa=new rsaCode();

3、在需要rsa加解密的组件使用工具

import {rsa} from '../../utils/rsaCode';

const cryptStr=rsa.encryptLong('要加密的内容')
//rsa.decryptLong(cryptStr)  解密
