  • sm4加密解密

    安装:

    npm install gm-crypt -S

     

    配置:

    onst SM4 = require('gm-crypt').sm4
    
    let sm4Config = {
      // encrypt/decypt main key; cannot be omitted
      key: 'JeF8U9wHFOMfs2Y8', //需要和后端一致
    
      // optional; can be 'cbc' or 'ecb'
      mode: 'cbc', // default
    
      // optional; when use cbc mode, it's �necessary
      iv: 'UISwD9fW6cFh9SNS', // default is null  cbc需要设置,ecb不需要
    
      // optional: this is the cipher data's type; Can be 'base64' or 'text'
      cipherType: 'base64' // default is base64
    }
    
    let sm4 = new SM4(sm4Config)

     

    加密:

    let plaintext = '中国国密加解密算法'
    let ciphertext = sm4.encrypt(plaintext)
    // ciphertext's result is 'j/+HgSpv8RZQI2YtSq0L1RnemiSokMm1VvLHSTt245U='

     

    解密:

    let ciphertext = 'j/+HgSpv8RZQI2YtSq0L1RnemiSokMm1VvLHSTt245U='
    let plaintext = sm4.decrypt(ciphertext)
    // plaintext's result is '中国国密加解密算法'

  • 导出插件file-saver.js

    可以将blob数据类型导出成图片、记事本txt,也可以将table、json导出成excel。

    官网:https://github.com/eligrey/FileSaver.js

    在线演示:https://www.jq22.com/jquery-info11353

     

    table导出成excel案例

    npm install file-saver --save
    npm install xlsx --save
    
    

     

    //以elm为例:
    在 table  添加 id='outTable'
    
    <el-table  id="outTable">

  • 群辉nas搭建git个人服务器

    1,安装git服务器

     

    2,创建用来存放git仓库的共享目录

     

    3,创建用来使用git的普通用户

     

    4,设置 Git Server ,允许刚创建的用户访问 Git Server

     

     

    5,打开NAS的家目录,并允许使用SSL连接

    NAS控制台-控件面板-用户账号-高级设置-家目录,启用家目录服务。如果不启用,则每次使用SSL登陆的时候会报一个目录不存在的错误。

    NAS控制台-控制面板-终端机和SNMP-终端机,启用SSH功能。

     

    6,登录ssh,切换超级管理员,并设置权限

    //创建仓库目录
    cd /volume1/gitReposTest/
    mkdir test.git

     

    然后继续 cd 进入仓库,初始化git仓库
    git init --bare

    接着是设置权限,按照图片顺序操作,即可

    到这里服务器端设置完成。

     

     

     

    客户端:

    //下载仓库,如果你做了内网穿透记得把ssh的默认22端口也映射出去
    git clone ssh://gitUserTest@192.168.2.98/volume1/gitReposTest/test.git
    
    //外网的:git clone ssh://gitUserTest@202.10.3.98:9000/volume1/gitReposTest/test.git

    接下来用常规操作即可:

    git add .
    git commit -m "add a file"
    git push
