1、npm引入crypto-js依赖

npm install crypto-js -D

npm install crypto-js -D

若出现报错，我的报错如下（可能是因为使用了淘宝镜像）：

npm ERR! code 1

所以之后我使用淘宝镜像进行安装

cnpm install crypto-js -D

cnpm install crypto-js -D

安装成功：

√ Installed 1 packages
√ Linked 0 latest versions
√ Run 0 scripts
√ All packages installed (1 packages installed from npm registry, used 283ms(network 278ms), speed 4.58kB/s, json 1(1.27kB), tarball 0B)

2、创建js文件引入crypto-js并写入加密方法

在src-assets文件夹下创建js文件 cryp.js

在cryp.js文件中引入crypto-js并写入加密方法：

import CryptoJS from 'crypto-js'

var cryptoObj = {
    /* 加密 */
    encryptFunc: (message) => {
        var key = '12345678900';//前后端约定好的秘钥
        var keyHex = CryptoJS.enc.Utf8.parse(key);
        var encrypted = CryptoJS.AES.encrypt(message, keyHex, {
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.Pkcs7
        });
        return encrypted.toString();

    },
}

export default cryptoObj;

3、在需要加密的组件内使用cryptoObj加密方法

<script>
  import  cryptoJSObj  from  '@/assets/cryp.js'
  export default {
  name: 'Login',
  data(){
    // 手机号码验证
    var contactPhone = (rule, value, callback) => {
      if (!value) {
        return callback(new Error('手机号不能为空'))
      } else {
        const reg = /^1[3|4|5|7|8][0-9]\d{8}$/
        if (reg.test(value)) {
          callback()
        } else {
          return callback(new Error('请输入正确的手机号'))
        }
      }
    };
    return{
      loading:false,
      form: {
        account: '',
        password: '',
      },

      formRules: {// 新增或编辑验证规则
        account: [
          { required: true, message: '账号不能为空' }
        ],
        password: [
          { required: true, message: '请输入密码', trigger: 'blur' },
          { min: 13, message: '密码长度应大于12位', trigger: 'blur' },
          { pattern: /^(?=.*[a-zA-Z])(?=.*[1-9])(?=.*[\W]).{13,}$/, message: '必须包含大小写字母、数字的组合、特殊字符，长度大于12位' }
        ],
      },
    }
  },
  created() {

  },
  methods:{
    startLogin:(){
      let password=cryptoJSObj.encryptFunc(form.password)
      //此处password为加密后的密码，form.password为输入的密码
    },
  }
}
</script>

到这里就全部完成了。
