终端导入crypto-js，执行一下命令

npm install crypto-js

成功后出现如图目录结构

uniapp新建utils目录

在utils目录下创建secret.js文件，文件内容如下：

//------------前后端用crypto.js加解密

//引入下载好的js文件
import CryptoJS from '../node_modules/crypto-js/crypto-js.js'

//---------------------加密方式
// 默认的 KEY 与 iv
const KEY = CryptoJS.enc.Utf8.parse('ABCDEFGHIJKLMNOP') // ''中与后台一样  密码
const IV = CryptoJS.enc.Utf8.parse('ABCDEFGHIJKLMNOP') // ''中与后台一样，


export function encrypt(word) {
  const key = KEY
  const iv = IV
  const srcs = CryptoJS.enc.Utf8.parse(word)
  var encrypted = CryptoJS.AES.encrypt(srcs, key, {
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.ZeroPadding
  })
  return CryptoJS.enc.Base64.stringify(encrypted.ciphertext)
}


export function decrypt(word) {
  const key = KEY
  const iv = IV
  const base64 = CryptoJS.enc.Base64.parse(word)
  const src = CryptoJS.enc.Base64.stringify(base64)
  var decrypt = CryptoJS.AES.decrypt(src, key, {
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.ZeroPadding
  })
  var decryptedStr = decrypt.toString(CryptoJS.enc.Utf8)
  return decryptedStr.toString()
}

1.3.1 界面引用

//方式1，绝对定位
import {encrypt,decrypt} from './utils/secret.js'
//方式2，绝对定位
import {encrypt,decrypt} from '@/utils/secret.js'
//方式3，相对定位
import {encrypt,decrypt } from '../../utils/secret.js'

1.3.2 调用加解密

let newpass=encrypt(password);//把密码加密后的密码

MySelfEDUtil.java 工具类

package com.cn.igwapi.common.util;

import org.apache.commons.codec.binary.Base64;
import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class MySelfEDUtil{
    // 使用AES-128-CBC加密模式，key需要为16位,key和iv可以相同！
    //密钥必须与前台的密钥保持一致
    private static String KEY = "ABCDEFGHIJKLMNOP";
    private static String IV = "ABCDEFGHIJKLMNOP";
    
    public static String encrypt(String data, String key, String iv) throws Exception
    {
        try
        {
            Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");// "算法/模式/补码方式"NoPadding PkcsPadding
            int blockSize = cipher.getBlockSize();

            byte[] dataBytes = data.getBytes();
            int plaintextLength = dataBytes.length;
            if (plaintextLength % blockSize != 0)
            {
                plaintextLength = plaintextLength + (blockSize - (plaintextLength % blockSize));
            }
            byte[] plaintext = new byte[plaintextLength];
            System.arraycopy(dataBytes, 0, plaintext, 0, dataBytes.length);
            SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
            IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());
            cipher.init(Cipher.ENCRYPT_MODE, keyspec, ivspec);
            byte[] encrypted = cipher.doFinal(plaintext);
            return new Base64().encodeToString(encrypted);
        }
        catch (Exception e)
        {
            e.printStackTrace();
            return null;
        }
    }

    
    public static String desEncrypt(String data, String key, String iv) throws Exception
    {
        try
        {
            byte[] encrypted1 = new Base64().decode(data);
            Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
            SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
            IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());
            cipher.init(Cipher.DECRYPT_MODE, keyspec, ivspec);
            byte[] original = cipher.doFinal(encrypted1);
            String originalString = new String(original);
            return originalString;
        }
        catch (Exception e)
        {
            e.printStackTrace();
            return null;
        }
    }

    
    public static String encrypt(String data) throws Exception
    {
        return encrypt(data, KEY, IV);
    }

    
    public static String desEncrypt(String data) throws Exception
    {
        return desEncrypt(data, KEY, IV);
    }
}

Main方法调试加解密

public static void main(String [] args){
    try {
        String realPassword = AesEncryptUtil.encrypt("123456");
        System.out.println("后端加密："+realPassword);
        String jm=AesEncryptUtil.desEncrypt(realPassword);
        System.out.println("解密后："+jm.trim());
    }catch (Exception e){
        e.printStackTrace();
    }
}

运行结果

至此前后端对应加解密就完成了，留个记录！！！
