vue crypto-js加解密

1.安装crypto-js

npm install crypto-js --save

2.编写encrypt.js 

const CryptoJS = require('crypto-js'); 
import md5 from 'js-md5';
var key_str = 'B120F1D92561A123';  //16位12进制字符串 ---秘钥
var iv_str ='1A123B120F1D9256';    //16位12进制字符串 ---偏移量
var key = CryptoJS.enc.Utf8.parse(key_str);
var iv = CryptoJS.enc.Utf8.parse(iv_str);


//加密方法
export function Encrypt(str) {
    let srcs = CryptoJS.enc.Utf8.parse(JSON.stringify(str));
    var encrypted = CryptoJS.AES.encrypt(srcs, key, {
        iv: iv,
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.Pkcs7
    });
    return CryptoJS.enc.Base64.stringify(encrypted.ciphertext);
}

//解密方法
export function Decrypt(str) {
    var decrypted = CryptoJS.AES.decrypt(str, key, {
        iv: iv,
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.Pkcs7
    });
    return  JSON.parse(CryptoJS.enc.Utf8.stringify(decrypted));
}

key_str:加密秘钥

iv_str:偏移量

3.axios请求拦截 进行加解密

import {
    Encrypt,
    Decrypt
   
} from "./cryptoJS.js"

const service = axios.create({
    baseURL: BASE_URL, 
    timeout: 30 * 1000 
});

//请求拦截进行参数加密
service.interceptors.request.use(
    config => {

        if (config.method == 'get' && config.params) {
            config.params.sign = objKeySort(config.params);
            config.params = {
                mini_sign: Encrypt(config.params)
            }
        }
        if (config.method == 'post' && config.data) {
            config.data.sign = objKeySort(config.data);
            config.data = {
                mini_sign: Encrypt(config.data)
            }
        }
        return config;
    },
    error => {
        // Do something with request error
        Promise.reject(error);
    }
);


// respone拦截器
service.interceptors.response.use(
    response => {
        //响应时进行解密
        let data = response.data;
        if (data.data && data.data.result) {
            data.data = Decrypt(data.data.result);
        } 
      
        return data;
    },
    error => {
        Message({
            message: error.message,
            type: "error",
            duration: 5 * 1000
        });
        return Promise.reject(error);
    }
);
